    Before: ROGERS, GRIFFITH and PILLARD, Circuit Judges.
    PER CURIAM: This case involves challenges to the most
    recent reforms of electric transmission planning and cost
    allocation adopted by the Federal Energy Regulatory
    Commission pursuant to the Federal Power Act, 16 U.S.C.
    § 791a et seq. In Order No. 1000, as reaffirmed and clarified in
    Order Nos. 1000-A and 1000-B (together, “the Final Rule”), the
    Commission required each transmission owning and operating
    public utility to participate in regional transmission planning
    that satisfies specific planning principles designed to prevent
    undue discrimination and preference in transmission service, and
    that produces a regional transmission plan. The local and
    regional transmission planning processes must consider
    transmission needs that are driven by public policy
    requirements. Transmission providers in neighboring planning
    regions must collectively determine if there are more efficient
    or cost-effective solutions to their mutual transmission needs.
    The Final Rule also requires each planning process to have a
    method for allocating ex ante among beneficiaries the costs of
    6
    new transmission facilities in the regional transmission plan, and
    the method must satisfy six regional cost allocation principles.
    Neighboring transmission planning regions also must have a
    common interregional cost allocation method for new
    interregional transmission facilities that satisfies six similar
    allocation principles. Additionally transmission providers are
    required to remove from their jurisdictional tariffs and
    agreements any provisions that establish a federal right of first
    refusal to develop transmission facilities in a regional
    transmission plan, subject to individualized compliance review.
    Forty-five petitioners and sixteen intervenors (hereinafter
    “petitioners”) include state regulatory agencies, electric
    transmission providers, regional transmission organizations, and
    electric industry trade associations. They challenge the
    Commission’s authority to adopt these reforms, and they
    contend that the Final Rule is arbitrary and capricious and
    unsupported by substantial evidence. For the following reasons,
    we conclude their contentions are unpersuasive. We hold in Part
    II, that the Commission had authority under Section 206 of the
    Federal Power Act to require transmission providers to
    participate in a regional planning process. In Part III, we
    conclude that there was substantial evidence of a theoretical
    threat to support adoption of the reforms in the Final Rule. In
    Part IV, we hold that the Commission had authority under
    Section 206 to require removal of federal rights of first refusal
    provisions upon determining they were unjust and unreasonable
    practices affecting rates, and that determination was supported
    by substantial evidence and was not arbitrary or capricious; we
    further hold that the Mobile-Sierra objection to the removal is
    not ripe. In Part V, we hold that the Commission had authority
    under Section 206 to require the ex ante allocation of the costs
    of new transmission facilities among beneficiaries, and that its
    decision regarding scope was not arbitrary or capricious. In Part
    VI, we hold that the Commission reasonably determined that
    7
    regional planning must include consideration of transmission
    needs driven by public policy requirements. In Part VII, we
    hold that the Commission reasonably relied upon the reciprocity
    condition to encourage non-public utility transmission providers
    to participate in a regional planning process. Accordingly, we
    deny the petitions for review of the Final Rule.1
    I.
    A brief overview of the Federal Power Act (“FPA”) and
    subsequent changes to the electric industry sets the background
    for petitioners’ challenges to the Final Rule. Upon enacting the
    FPA, Congress determined that federal regulation of interstate
    electric energy transmission and its sale at wholesale is
    “necessary in the public interest,” FPA § 201(a), 16 U.S.C.
    § 824(a), and vested the Commission with “jurisdiction over all
    facilities for such transmission or sale,” 
    id. § 201(b)(1),
    16
    U.S.C. § 824(b)(1). The States would retain authority over “any
    other sale of electric energy” and facilities used for “generation
    of electric energy,” “local distribution,” or “transmission of
    electric energy in intrastate commerce.” 
    Id. The Commission
    was directed “to divide the country into regional districts for the
    voluntary interconnection and coordination of facilities for the
    generation, transmission, and sale of electric energy,” and
    assigned the “duty” to “promote and encourage such
    interconnection and coordination.” FPA § 202(a), 16 U.S.C.
    § 824a(a). Such public utilities, in turn, were required to file
    new rates for Commission approval, and Congress directed that
    “[a]ll rates and charges made, demanded, or received by any
    public utility for or in connection with the [jurisdictional]
    transmission or sale of electric energy . . . shall be just and
    reasonable,” and that “[n]o public utility shall, with respect to
    1
    Judge Rogers wrote Parts I, II.A–B, and III; Judge Griffith
    wrote Parts II.C, IV, and VI; and Judge Pillard wrote Parts V and VII.
    8
    any [jurisdictional] transmission or sale . . . subject any person
    to any undue prejudice or disadvantage” or “maintain any
    unreasonable difference in rates, charges, service, facilities, or
    in any other respect, either as between localities or as between
    classes of service.” FPA § 205(a)–(b), 16 U.S.C. § 824d(a)–(b).
    Additionally, Congress empowered the Commission to take
    action on its own motion in order to ensure that such rates,
    charges, and classifications, as well as “any rule, regulation,
    practice, or contract affecting such rate, charge, or
    classification,” are not “unjust, unreasonable, unduly
    discriminatory or preferential.” FPA § 206(a), 16 U.S.C.
    § 824e(a).
    When Congress enacted the FPA in 1935, electric utilities
    were mostly vertically integrated firms that constructed and
    operated their own generation, transmission, and distribution
    facilities. See New York v. FERC, 
    535 U.S. 1
    , 5 (2002). The
    firms acted as separate, local monopolies, and consumers paid
    a single “bundled” rate for delivered electricity. 
    Id. Sixty years
    later, the electric industry had experienced fundamental changes:
    Electric systems had become increasingly interconnected, long-
    distance transmission had become increasingly economical, and
    smaller, lower-cost power plants had begun to emerge as
    competitors to the vertically integrated utilities. See Order No.
    888, Promoting Wholesale Competition Through Open Access
    Non-Discriminatory Transmission Services by Public Utilities,
    F.E.R.C. Stats. & Regs. ¶ 31,036 at pp. 31,639–44, 61 Fed. Reg.
    21,540, 21,543–46 (1996).
    The Commission responded to these changes and market
    conditions by adopting reforms to the electric industry that were
    modeled after those it had adopted for the natural gas industry
    pursuant to the Natural Gas Act, 15 U.S.C. § 717 et seq. See
    generally Associated Gas Distribs. v. FERC, 
    824 F.2d 981
    (D.C.
    Cir. 1987) (reviewing Order No. 436). The Commission
    9
    concluded that the economic self-interest of electric
    transmission monopolists lay in denying transmission or
    offering it only on inferior terms to emerging competitors. See
    Order No. 888 at p. 31,682, 61 Fed. Reg. at 21,567. Given this
    intrinsic defect in how the market was shaping the electric
    industry, the Commission acted to foster “a successful transition
    to competitive wholesale electricity markets.” 
    Id. at p.
    31,652,
    61 Fed. Reg. at 21,550. In Order No. 888, the Commission
    required each jurisdictional electric public transmission provider
    to “functional[ly] unbundl[e]” its wholesale generation and
    transmission services and file an open-access transmission tariff
    (“OATT”) containing minimum terms of non-discriminatory
    transmission service. 
    Id. at pp.
    31,635–36, 31,653–54, 61 Fed.
    Reg. at 21,541, 21,551–52. Through these structural changes,
    the Commission sought to open the electric grid to all sources of
    electric power and thereby “ensure that customers have the
    benefits of competitively priced generation.” 
    Id. at p.
    31,652, 61
    Fed. Reg. at 21,550. To promote development of competitive
    markets, the Commission encouraged the formation of regional
    transmission organizations (“RTOs”) and independent system
    operators (“ISOs”) to coordinate transmission planning,
    operation, and use on a regional and interregional basis. 
    Id. at pp.
    31,655, 31,854–55, 61 Fed. Reg. at 21,552, 21,666–67. This
    court in Transmission Access Policy Study Group v. FERC, 
    225 F.3d 667
    (D.C. Cir. 2000) (“TAPS”), aff’d sub nom. New York,
    
    535 U.S. 1
    , upheld Order No. 888 in nearly all respects,
    concluding that the Commission had authority under FPA
    Section 206 to require open access as a generic remedy for
    systemic anti-competitive behavior, see 
    id. at 685–87.
    Congress also acted to spur investment in the electric
    transmission grid. Under the Electricity Modernization Act of
    2005, enacted as Title XII of the Energy Policy Act of 2005,
    Pub. L. No. 109-58, 119 Stat. 594, 941, the Commission was
    authorized: to grant permits for construction of interstate
    10
    transmission facilities in “national interest electric transmission
    corridors,” 
    id. § 1221(b)
    (codified at FPA § 216(b), 16 U.S.C.
    § 824p(b)); to subsidize the development of technology that
    would increase the capacity, efficiency, or reliability of
    transmission facilities, 
    id. §§ 1223–24
    (codified at 42 U.S.C.
    §§ 16422–23); to provide incentive-based rates for investments
    in transmission infrastructure, 
    id. § 1241
    (codified at FPA § 219,
    16 U.S.C. § 824s); and to require each “unregulated transmitting
    utility” to provide transmission services on terms and conditions
    “comparable to those under which [it] provides transmission
    services to itself and that are not unduly discriminatory or
    preferential,” 
    id. § 1231,
    (codified at FPA § 211A(b), 16 U.S.C.
    § 824j-1(b)). Further, the Commission was instructed to
    exercise its authority under the FPA “in a manner that facilitates
    the planning and expansion of transmission facilities to meet the
    reasonable needs of load-serving entities.” 
    Id. § 1233
    (codified
    at FPA § 217(b)(4), 16 U.S.C. § 824q(b)(4)). The Commission
    was to establish mandatory reliability standards for “bulk power
    system” operators in conjunction with the North American
    Electric Reliability Corporation (“NERC”), the industry’s self-
    regulatory organization. 
    Id. § 1211(a)
    (codified at FPA § 215,
    16 U.S.C. § 824o); see N. Am. Elec. Reliability Corp., 116
    F.E.R.C. ¶ 61,062 at ¶ 240 (July 20, 2006).
    In 2007, the Commission issued Order No. 890, Preventing
    Undue Discrimination and Preference in Transmission Service,
    F.E.R.C. Stats. & Regs. ¶ 31,241, 72 Fed. Reg. 12,266 (2007).
    Noting that the United States had “witnessed a decline in
    transmission investment relative to load growth,” the
    Commission found that the resulting grid congestion “can have
    significant cost impacts on consumers.” 
    Id. ¶¶ 60,
    421, 72 Fed.
    Reg. at 12,276, 12,318. Concluding that transmission providers
    lacked incentives to plan and develop new transmission facilities
    in a manner consistent with the public interest, the Commission
    found that the “lack of coordination, openness, and
    11
    transparency” in transmission planning had “result[ed] in
    opportunities for undue discrimination” because “participants
    ha[d] no means to determine whether the plan developed by the
    transmission provider in isolation is unduly discriminatory.” 
    Id. ¶¶ 57–61,
    421–425, 72 Fed. Reg. at 12,275–76, 12,318. To
    “remedy these transmission planning deficiencies” and “prevent
    undue discrimination in the rates, terms and conditions of public
    utility transmission service,” Order No. 890 required each
    transmission provider to establish an open, transparent, and
    coordinated transmission planning process that complied with
    nine planning principles. 
    Id. ¶ 425
    & app. C, attachment K, 72
    Fed. Reg. at 12,318, 12,531. Transmission providers were also
    required “to open their transmission planning process to
    customers, coordinate with customers regarding future system
    plans, and share necessary planning information with
    customers.” 
    Id. ¶ 3,
    72 Fed. Reg. at 12,267.
    By late 2008, the electric industry was reporting that an
    estimated $298 billion of investment in new electric
    transmission facilities would be needed between 2010 and 2030
    to maintain current levels of reliable electric service across the
    United States. See Marc W. Chupka et al., Transforming
    America’s Power Industry: The Investment Challenge
    2010–2030, at 37 (Nov. 2008). NERC, the electric industry’s
    self-regulator, projected that in the next decade a 9.5% to 15%
    increase in circuit miles of transmission would be needed to
    maintain reliability and to “unlock” and integrate renewable
    resources like wind generation that are likely to be remote from
    demand centers.         NERC, 2009 Long-Term Reliability
    Assessment 26 (Oct. 2009); NERC, 2008 Long-Term Reliability
    Assessment 15 (Oct. 2008). The Energy Department had
    similarly determined that “under any future electric industry
    scenario,” a “[s]ignificant expansion of the transmission grid
    will be required” to “increase reliability, reduce costly
    congestion and line losses, and supply access to low-cost remote
    12
    resources, including renewables.” Dep’t of Energy, 20% Wind
    Energy by 2030: Increasing Wind Energy’s Contribution to
    U.S. Electricity Supply 93 (July 2008).
    In September 2009, the Commission convened three
    regional technical conferences to “examine whether existing
    transmission planning processes adequately consider needs and
    solutions on a regional or interconnection-wide basis to ensure
    adequate and reliable supplies at just and reasonable rates.”
    FERC, Notice of Technical Conferences, Docket No. AD09-8-
    000, at 2 (June 30, 2009). The conferences were also to
    “explore whether existing processes are sufficient to meet
    emerging challenges to the transmission system, such as the
    development of interregional transmission facilities, the
    integration of large amounts of location-constrained generation,
    and the interconnection of distributed energy resources.” 
    Id. While the
    Commission was evaluating the adequacy of Order
    No. 890’s reforms, Congress provided $80 million to the
    Department of Energy “for the purpose of facilitating the
    development of regional transmission plans,” through analysis
    of future demand and transmission requirements and technical
    assistance to transmission providers in developing
    interconnection-based transmission plans for the Eastern,
    Western, and Texas Interconnections. American Recovery and
    Reinvestment Act of 2009, Pub. L. No. 111-5, div. A, 123 Stat.
    115, 139.
    In June 2010, the Commission published a Notice of
    Proposed Rulemaking. Transmission Planning and Cost
    Allocation by Transmission Owning and Operating Public
    Utilities, 131 F.E.R.C. ¶ 61,253, 75 Fed. Reg. 37,884 (2010)
    (“NPRM”).       The Commission explained that although
    substantial improvements in the transmission planning process
    had occurred as a result of compliance with Order No. 890,
    “significant changes in the nation’s electric power industry”
    13
    since then required consideration of additional reforms. See 
    id. ¶ 33,
    75 Fed. Reg. at 37,889. Among other things, the
    Commission identified “a trend of increased investment in the
    country’s transmission infrastructure” due principally to
    investment in transmission of renewable energy sources. 
    Id. ¶ 33
    & n.41, 75 Fed. Reg. at 37,889. Although governmental
    reforms and market forces had resulted in expansion of the
    transmission grid, the Commission concluded that this positive
    trend highlighted deficiencies in existing transmission planning
    and cost allocation processes that would inhibit the construction
    of new transmission facilities and adversely affect rates if left
    unremedied. See 
    id. ¶¶ 32–42,
    75 Fed. Reg. at 37,889–90. The
    Commission identified five general deficiencies in Order No.
    890, see 
    id. ¶¶ 35–41,
    75 Fed. Reg. at 37,889–90, and proposed
    additional reforms “to correct [those] deficiencies . . . so that the
    transmission grid can better support wholesale power markets
    and thereby ensure that Commission-jurisdictional services are
    provided at rates, terms and conditions that are just and
    reasonable and not unduly discriminatory or preferential,” 
    id. ¶ 1,
    75 Fed. Reg. at 37,885.
    In August 2011, the Commission issued Order No. 1000,
    which adopted the proposed reforms. Transmission Planning
    and Cost Allocation by Transmission Owning and Operating
    Public Utilities, F.E.R.C. Stats. & Regs. ¶ 31,323, 76 Fed. Reg.
    49,842 (2011). Under Order No. 1000:
    (1) Each transmission provider must participate in a
    regional transmission planning process that complies with the
    planning principles in Order No. 890, produces a regional
    transmission plan for development of new regional transmission
    facilities, and includes procedures to identify transmission needs
    driven by public policy requirements established by federal,
    state, or local laws or regulations and evaluate potential
    14
    solutions to those needs. 
    Id. ¶¶ 2,
    146, 203–05, 76 Fed. Reg. at
    49,845, 49,867, 49,876–77.
    (2) Neighboring transmission planning regions must
    establish interregional coordination procedures that provide for
    sharing information and planning data as well as the
    identification and joint evaluation of interregional transmission
    facilities that could address transmission needs more efficiently
    or cost-effectively than separate regional transmission facilities.
    
    Id. ¶¶ 393,
    396, 76 Fed. Reg. at 49,907.
    (3) Transmission providers must remove from
    jurisdictional tariffs and agreements any provisions that
    establish a federal right of first refusal for an incumbent
    transmission developer to construct new regional transmission
    facilities included in a regional transmission plan. 
    Id. ¶ 313,
    76
    Fed. Reg. at 49,895–96. An “incumbent” transmission provider
    refers to a public utility transmission provider that develops a
    transmission project within its own retail distribution service
    territory, while a “non-incumbent” transmission provider refers
    to either a transmission developer without a retail distribution
    service territory or a public utility transmission provider that
    proposes a transmission project outside its existing retail
    distribution service territory. 
    Id. ¶ 225,
    76 Fed. Reg. at 49,880.
    (4) Each transmission provider must demonstrate that
    the regional planning process in which it participates has
    established appropriate qualification criteria for transmission
    developers, identified the information that a transmission
    developer must submit in proposing a regional transmission
    project, and has a selection process for transmission projects that
    is transparent and not unduly discriminatory. 
    Id. ¶¶ 323–31,
    76
    Fed. Reg. at 49,897–99.
    15
    The cost-allocation reforms in Order No. 1000 require each
    transmission provider to include in its OATT a method (or set of
    methods) for allocating ex ante the costs of new regional
    transmission facilities that complies with six regional cost
    allocation principles. 
    Id. ¶ 558,
    76 Fed. Reg. at 49,929. Those
    principles include cost causation, under which “[t]he cost of
    transmission facilities must be allocated to those within the
    transmission planning region that benefit from those facilities in
    a manner that is at least roughly commensurate with estimated
    benefits.” 
    Id. ¶ 586,
    76 Fed. Reg. at 49,932. Transmission
    providers in neighboring transmission planning regions are
    similarly required to establish a common method (or set of
    methods) for allocating ex ante the costs of a new transmission
    facility to be located in both planning regions that complies with
    interregional cost allocation principles closely tracking the
    regional cost allocation principles. 
    Id. ¶¶ 578,
    611, 76 Fed. Reg.
    at 49,931, 49,936. Participant funding of new transmission
    facilities (i.e., allocating the costs of a transmission facility only
    to entities that volunteer to bear those costs) is not permitted as
    a regional or interregional cost allocation method. 
    Id. ¶¶ 723–25,
    76 Fed. Reg. at 49,949–50.
    Upon rehearing, the Commission clarified and reaffirmed
    the reforms in Order No. 1000. See Order No. 1000-A, 139
    F.E.R.C. ¶ 61,132, 77 Fed. Reg. 32,184 (2012); Order No. 1000-
    B, 141 F.E.R.C. ¶ 61,044, 77 Fed. Reg. 64,890 (2012). The
    Commission rejected requests to eliminate or substantially
    modify Order No. 1000 and provided clarifications relating to
    scope, terminology, and underlying reasons for certain reforms.
    See, e.g., Order No. 1000-A ¶¶ 3, 190, 204, 216, 77 Fed. Reg. at
    32,186, 32,215, 32,217, 32,219. Notably, the Commission
    stated that it was “not requiring . . . providers to eliminate a
    federal right of first refusal before the Commission makes a
    determination regarding whether an agreement is protected by
    16
    a Mobile-Sierra[2] provision.” 
    Id. ¶ 389,
    77 Fed. Reg. at 32,245.
    In Order No. 1000-B, the Commission provided clarifications
    and restated that the obligation to remove federal rights of first
    refusal would arise only after an individualized determination.
    See Order No. 1000-B ¶¶ 8, 11, 40, 72, 77 Fed. Reg. at 64,892,
    64,897, 64,902.
    Petitioners challenge the Final Rule on the grounds that the
    Commission lacked statutory authority, made factual findings
    that were unsupported by substantial evidence, and acted in a
    manner that was arbitrary or capricious or contrary to law. In
    addressing these contentions, the court is bound to apply the
    following standards of review.
    The court reviews challenges to the Commission’s
    interpretation of the FPA under the familiar two-step framework
    of Chevron U.S.A. Inc. v. Natural Resources Defense Council,
    Inc., 
    467 U.S. 837
    (1984). If the court determines “Congress
    has directly spoken to the precise question at issue,” and “the
    intent of Congress is clear, that is the end of the matter.” 
    Id. at 842.
    If, however, “the statute is silent or ambiguous with
    respect to the specific issue,” then the court must determine
    “whether the agency’s answer is based on a permissible
    construction of the statute.” 
    Id. at 843.
    “No matter how it is
    framed, the question a court faces when confronted with an
    agency’s interpretation of a statute it administers is always,
    simply, whether the agency has stayed within the bounds of its
    statutory authority,” City of Arlington v. FCC, 
    133 S. Ct. 1863
    ,
    1868 (2013) (emphasis omitted), and the court will defer to the
    Commission’s reasonable interpretation of statutory ambiguities
    concerning both the scope of its statutory authority and the
    application of that authority, see 
    id. 2 United
    Gas Pipe Line Co. v. Mobile Gas Serv. Corp., 
    350 U.S. 332
    (1956); FPC v. Sierra Pac. Power Co., 
    350 U.S. 348
    (1956).
    17
    The court must uphold the Final Rule unless it is arbitrary,
    capricious, an abuse of discretion, or otherwise not in
    accordance with law. See Midwest ISO Transm. Owners v.
    FERC, 
    373 F.3d 1361
    , 1368 (D.C. Cir. 2004) (citing 5 U.S.C.
    § 706(2)(A)). The Commission must “examine the relevant data
    and articulate a satisfactory explanation for its action including
    a rational connection between the facts found and the choice
    made.” Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. State Farm
    Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983) (internal quotation
    marks omitted). The Commission’s factual findings are
    conclusive if supported by substantial evidence. 16 U.S.C.
    § 825l(b). Substantial evidence “is such relevant evidence as a
    reasonable mind might accept as adequate to support a
    conclusion,” Murray Energy Corp. v. FERC, 
    629 F.3d 231
    , 235
    (D.C. Cir. 2011) (internal quotation marks omitted), and requires
    “more than a scintilla” but “less than a preponderance” of
    evidence, Fla. Gas Transm. Co. v. FERC, 
    604 F.3d 636
    , 645
    (D.C. Cir. 2010) (quoting FPL Energy Me. Hydro LLC v. FERC,
    
    287 F.3d 1151
    , 1160 (D.C. Cir. 2002)). When applied to
    rulemaking proceedings, the substantial evidence test “is
    identical to the familiar arbitrary and capricious standard,”
    which “requires the Commission to specify the evidence on
    which it relied and to explain how that evidence supports the
    conclusion it reached.” Wis. Gas Co. v. FERC, 
    770 F.2d 1144
    ,
    1156 (D.C. Cir. 1985) (internal quotation marks omitted).
    Furthermore, in rate-related matters, the court’s review of
    the Commission’s determinations is particularly deferential
    because such matters are either fairly technical or “involve
    policy judgments that lie at the core of the regulatory mission.”
    Alcoa Inc. v. FERC, 
    564 F.3d 1342
    , 1347 (D.C. Cir. 2009)
    (internal quotation mark omitted). The court owes the
    Commission “great deference” in this realm because “[t]he
    statutory requirement that rates be ‘just and reasonable’ is
    obviously incapable of precise judicial definition,” Morgan
    18
    Stanley Capital Grp. Inc. v. Pub. Util. Dist. No. 1, 
    554 U.S. 527
    ,
    532 (2008), and “the Commission must have considerable
    latitude in developing a methodology responsive to its
    regulatory challenge,” Am. Pub. Gas Ass’n v. FPC, 
    567 F.2d 1016
    , 1037 (D.C. Cir. 1977) (citing Permian Basin Area Rate
    Cases, 
    390 U.S. 747
    , 790 (1968)).
    II.
    Mandatory Regional Planning: Statutory Authority. In
    adopting the transmission planning reforms in the Final Rule,
    the Commission relied on FPA Section 206. See Order No.
    1000 ¶ 99, 76 Fed. Reg. at 49,860. Petitioners contend that
    although “[FPA] Sections 205 and 206 empower [the
    Commission] to ensure that transactions involving voluntary
    planning arrangements are just, reasonable, and
    nondiscriminatory,” the Commission lacks authority “to
    mandate transmission planning in the first instance” because the
    FPA “only allows [the Commission] to regulate existing
    voluntary commercial relationships.” Pet’rs’ Threshold Br. 3.
    Petitioners also contend that Sections 201 and 202(a) preclude
    the Commission’s planning mandate.
    In addressing issues of statutory interpretation, the court
    must begin with the text, turning as need be to the structure,
    purpose, and context of the statute. See Caraco Pharm. Labs.,
    Ltd. v. Novo Nordisk A/S, 
    132 S. Ct. 1670
    , 1680–81 (2012); N.Y.
    State Conference of Blue Cross & Blue Shield Plans v. Travelers
    Ins. Co., 
    514 U.S. 645
    , 655 (1995); Petit v. U.S. Dep’t of Educ.,
    
    675 F.3d 769
    , 781–82 (D.C. Cir. 2012).
    A.
    Section 206(a) provides, in relevant part:
    19
    Whenever the Commission, after a hearing held upon
    its own motion or upon complaint, shall find that any
    rate, charge, or classification, demanded, observed,
    charged, or collected by any public utility for any
    transmission or sale subject to the jurisdiction of the
    Commission, or that any rule, regulation, practice, or
    contract affecting such rate, charge, or classification is
    unjust, unreasonable, unduly discriminatory or
    preferential, the Commission shall determine the just
    and reasonable rate, charge, classification, rule,
    regulation, practice, or contract to be thereafter
    observed and in force, and shall fix the same by order.
    16 U.S.C. § 824e(a)(emphasis added). By its plain terms,
    Section 206 instructs the Commission to remedy “any . . .
    practice” that “affect[s]” a rate for interstate electricity
    transmission services “demanded” or “charged” by “any public
    utility” if such practice “is unjust, unreasonable, unduly
    discriminatory or preferential.” 
    Id. The text
    does not define
    “practice,” although use of the word “any” amplifies the breadth
    of the delegation to the Commission. See United States v.
    Gonzales, 
    520 U.S. 1
    , 5 (1997).
    In the Final Rule, the Commission identified underlying
    problems with “existing transmission planning processes” and
    found that those processes “have a direct and discernable affect
    [sic] on rates,” explaining that “[i]t is through the transmission
    planning process that . . . providers determine which
    transmission facilities will more efficiently or cost-effectively
    meet the needs of the region, the development of which directly
    impacts the rates, terms and conditions of jurisdictional service.”
    Order No. 1000 ¶¶ 112, 116, 76 Fed. Reg. at 49,862. The
    Commission concluded that “for the pro forma OATT (and,
    consequently, public utility transmission providers’ OATTs) to
    be just and reasonable and not unduly discriminatory or
    20
    preferential, it must be revised.” 
    Id. ¶ 116,
    76 Fed. Reg. at
    49,862. To remedy the identified systemic problems, the
    Commission mandated that all transmission providers not only
    participate in a planning process that is open and transparent as
    Order No. 890 requires, but also one that is regional in scope
    and produces a transmission plan whereby providers have the
    information needed to determine which projects satisfy local and
    regional needs more efficiently and effectively. Also, the plan
    must consider transmission needs driven by public policy
    requirements, not be impeded by federal rights of first refusal
    allowing preferences in favor of incumbents, and allocate ex
    ante among beneficiaries the costs of new transmission
    facilities. See 
    id. ¶¶ 146–48,
    151, 203, 313, 499, 76 Fed. Reg.
    at 49,867–68, 49,876, 49,895–96, 49,921.
    Petitioners challenge neither the Commission’s conclusion
    that the current transmission planning processes are “practices”
    under Section 206, see, e.g., 
    id. ¶ 58,
    76 Fed. Reg. at 49,853, nor
    its conclusion that such transmission planning practices directly
    affect rates, see 
    id. ¶ 112,
    76 Fed. Reg. at 49,862; see also Oral
    Arg. Tr. at 10:5–19. Neither can they dispute that the
    Commission is obligated by the plain text of Section 206 to
    ensure that such practices are just and reasonable and not unduly
    discriminatory or preferential. Instead petitioners maintain
    essentially that a lack of regional transmission planning was not
    an existing practice subject to the Commission’s authority under
    Section 206, and that “the decision whether to coordinate
    planning is left, in the first instance, to utilities.” Pet’rs’
    Threshold Br. 8. Petitioners rely on Atlantic City Electric Co.
    v. FERC, 
    295 F.3d 1
    , 10 (D.C. Cir. 2002), for the proposition
    that the Commission is “limited under section 206 to
    investigat[ing] the reasonableness of the terms of existing
    utility-customer relationships.” Pet’rs’ Threshold Br. 8. But in
    Atlantic City the court stated that Section 206 permits the
    Commission “to initiate changes to existing utility rates and
    21
    
    practices,” 295 F.3d at 10
    , which is what the Commission claims
    to have done in the Final Rule. Petitioners’ reliance on Atlantic
    City is misplaced because it begs the question of what “practice”
    means.
    The authority and obligation that Congress vested in the
    Commission to remedy certain practices is broadly stated and
    the only question is what limits are fairly implied. On the one
    hand, Section 206 cannot be fairly viewed as the type of “subtle
    device” at issue in MCI Telecommunications Corp. v. AT&T
    Co., 
    512 U.S. 218
    , 224, 231 (1994), on which petitioners rely.
    There, the Supreme Court rejected the agency’s attempt to
    interpret its statutory authority to “modify any requirement” to
    extend to a fundamental change to a tariff-filing requirement of
    “enormous importance to the statutory scheme.” 
    Id. On the
    other hand, in California Independent System Operator Corp. v.
    FERC, 
    372 F.3d 395
    , 398 (D.C. Cir. 2004) (“CAISO”), this court
    held that the Commission had exceeded its authority under
    Section 206 by calling for the replacement of a public utility’s
    board of directors. The court explained that “[t]he word
    ‘practices’ is a word of sufficiently diverse definitions that the
    only realistic approach to determining Congress’s ‘plain
    meaning,’ if any, is to regard the word in its context.”
    Understood in the context of Section 206’s transactional terms,
    the court observed, “[i]t is quite a leap” to move from the
    authority to regulate rates, charges, classifications and closely
    related matters to “an implication that by the word ‘practice,’
    Congress empowered the Commission . . . to reform completely
    the governing structure of [an ISO].” 
    Id. Significantly for
    present purposes, the court distinguished such an expansive
    interpretation of the word “practices” from Commission action
    to “effect a reformation of some ‘practice’ in a more traditional
    sense of actions habitually being taken by a utility in connection
    with a rate found to be unjust or unreasonable.” 
    Id. 22 Reforming
    the practices of failing to engage in regional
    planning and ex ante cost allocation for development of new
    regional transmission facilities is not the kind of interpretive
    “leap” that concerned the court in CAISO but rather involves a
    core reason underlying Congress’ instruction in Section 206.
    This is illustrated by the court’s decision in TAPS, 
    225 F.3d 667
    .
    There, the court upheld Order No. 888 mandating the
    unbundling of generation and transmission services and the
    filing of OATTs as a remedy for the refusal of transmission-
    owning facilities to offer transmission to emerging competitors
    on non-discriminatory terms. The Commission found that these
    facilities “c[ould] be expected to act in their own interest to
    maintain their monopoly” by either “denying transmission
    access outright” or “by providing transmission services to
    competitors only at comparatively unfavorable rates, terms, and
    conditions.” 
    Id. at 683–84.
    Although some facilities had
    voluntarily opened their transmission facilities to third parties,
    the Commission concluded that “relying upon voluntary
    arrangements . . . would not remedy the fundamentally anti-
    competitive structure of the transmission industry.” 
    Id. at 684.
    The court deferred to the Commission’s reasonable
    interpretation that it had “authority under FPA §§ 205 and 206
    to require open access as a generic remedy to prevent undue
    discrimination.” 
    Id. at 687.
    Notably, then, in TAPS, the court
    agreed with the Commission’s interpretation here that a failure
    to act qualifies as a “practice” under Section 206 that it must
    remedy when the failure to act is “unjust, unreasonable, unduly
    discriminatory or preferential,” 16 U.S.C. § 824e(a), and directly
    affects or is closely related to jurisdictional rates, see 
    CAISO, 372 F.3d at 403
    .
    Petitioners attempt to distinguish TAPS by characterizing
    regional transmission plans as “regional planning agreements”
    and “[a]greements to coordinate transmission planning” that
    require transmission providers to take on “binding” commercial
    23
    obligations. See Oral Arg. Tr. at 3:19–21, 11:6–13; Pet’rs’
    Threshold Br. 13. They rely on Otter Tail Power Co. v. United
    States, 
    410 U.S. 366
    (1973), for the proposition that Congress
    intended the formation of such agreements to be “voluntary” and
    “governed in the first instance by business judgment,” 
    id. at 374;
    see Oral Arg. Tr. at 3, 11:6–13; Pet’rs’ Threshold Br. 8, 13.
    This misperceives what the Commission has required in the
    Final Rule. In Order No. 1000, the Commission expressly
    “decline[d] to impose obligations to build or mandatory
    processes to obtain commitments to construct transmission
    facilities in the regional transmission plan.” Order No. 1000 ¶
    159, 76 Fed. Reg. at 49,870. More generally, the Commission
    disavowed that it was purporting to “determine what needs to be
    built, where it needs to be built, and who needs to build it.” 
    Id. ¶ 49,
    76 Fed. Reg. at 49,852. As the Commission explained on
    rehearing, “Order No. 1000’s transmission planning reforms are
    concerned with process” and “are not intended to dictate
    substantive outcomes.” Order No. 1000-A ¶ 188, 77 Fed. Reg.
    at 32,215. The substance of a regional transmission plan and
    any subsequent formation of agreements to construct or operate
    regional transmission facilities remain within the discretion of
    the decision-makers in each planning region.
    In TAPS, the court rejected petitioners’ interpretation of
    Otter Tail. That was an antitrust enforcement action in which
    the Supreme Court held that an electric power company was not,
    by reason of the Commission’s authority under the FPA to
    compel involuntary interconnections of power, immune from
    antitrust regulation for its refusals to sell at wholesale or to
    transfer power to 
    municipalities. 410 U.S. at 373
    . The Court
    noted that, as originally proposed, the FPA would have made
    public utilities common carriers and empowered the
    Commission to order the wheeling of power if it was “necessary
    or desirable in the public interest,” but these provisions were
    eliminated and replaced by involuntary wheeling authority
    24
    “subject to limitations unrelated to antitrust considerations” in
    order to “preserve the voluntary action of the utilities.” 
    Id. at 373–74
    (internal quotation marks omitted). Based on this
    legislative history, the Court explained that “Congress rejected
    a pervasive regulatory scheme for controlling the interstate
    distribution of power in favor of voluntary commercial
    relationships,” and that “[w]hen these relationships are governed
    in the first instance by business judgment and not regulatory
    coercion, courts must be hesitant to conclude that Congress
    intended to override the fundamental national policies embodied
    in the antitrust laws.” 
    Id. at 374
    (emphasis added). In TAPS,
    this court concluded that “while Otter Tail may represent a
    general rule that [the Commission]’s authority to order open
    access is limited, the FPA, like the [Natural Gas Act], makes an
    exception to that rule where [the Commission] finds undue
    
    discrimination.” 225 F.3d at 686
    –87 (citing Associated Gas
    
    Distributors, 824 F.2d at 998
    ). The court thus recognized that
    Otter Tail did not purport to limit the Commission’s Section 206
    authority to remedy practices affecting rates that are unduly
    discriminatory. Rather, the Supreme Court in Otter Tail
    concluded that the FPA does not preempt the field of electric
    utility regulation.
    In their Reply Brief, petitioners attempt to inject another
    reason the Commission lacked authority under Section 206,
    maintaining that the Commission’s regional planning mandate
    “is not requiring a change to existing practices,” but is instead
    “a directive to engage in new practices by unlawfully
    compelling formation of new commercial relationships,” i.e.,
    “coordinated planning arrangements.” Pet’rs’ Threshold Reply
    Br. 11. The court ordinarily refuses to address arguments first
    presented in a reply brief, see Domtar Me. Corp. v. FERC, 
    347 F.3d 304
    , 309–10 (D.C. Cir. 2003), because the opposing party
    has no opportunity to respond. We note, however, that to the
    extent this is not a reiteration of petitioners’ Otter Tail
    25
    argument, it is based on a false premise. Commission-mandated
    transmission planning is not new. See Order No. 890 ¶ 3, 72
    Fed. Reg. at 12,267. The Final Rule builds on Order No. 890’s
    requirements in light of changed circumstances and is simply the
    next step in a series of related reforms that began no later than
    Order No. 888. See Order No. 1000 ¶ 99, 76 Fed. Reg. at
    49,860. For the reasons discussed, we conclude, consistent with
    the deferential standard in step two of the Chevron 
    analysis, 467 U.S. at 843
    , that the Commission reasonably interpreted Section
    206 to authorize the Final Rule’s planning mandate. See 
    TAPS, 225 F.3d at 687
    , aff’d sub nom. New York, 
    535 U.S. 1
    .
    B.
    Petitioners’ principal objection, in any event, is that Section
    202(a) bars the Commission from mandating transmission
    planning.
    Section 202(a) provides, in relevant part:
    For the purpose of assuring an abundant supply of
    electric energy throughout the United States with the
    greatest possible economy and with regard to the
    proper utilization and conservation of natural
    resources, the Commission is empowered and directed
    to divide the country into regional districts for the
    voluntary interconnection and coordination of facilities
    for the generation, transmission, and sale of electric
    energy . . . . It shall be the duty of the Commission to
    promote and encourage such interconnection and
    coordination within each such district and between
    such districts.
    16 U.S.C. § 824a(a) (emphasis added). The Commission
    concluded Section 202(a) posed no bar to adoption of the
    challenged transmission planning reforms because
    26
    “coordination” refers to the coordinated operation of existing
    transmission facilities, not to the planning of future facilities.
    See Order No. 1000 ¶ 100, 76 Fed. Reg. at 49,860; Order No.
    1000-A ¶ 123, 77 Fed. Reg. at 32,206. The Commission
    explained that the coordinated operation contemplated by
    Section 202(a), as a practical matter, “can occur only after the
    facilities are interconnected.” Order No. 1000-A ¶ 124, 77 Fed.
    Reg. at 32,206. By contrast, “[t]he planning of new
    transmission facilities occurs before they can be
    interconnected,” and thus “any transmission planning relevant
    to [new transmission] facilities occurs prior to those matters that
    [Section 202(a)] mandates be voluntary.” 
    Id. ¶ 125,
    77 Fed.
    Reg. at 32,206.
    In petitioners’ view, the meaning of “coordination” is “self-
    evident,” Pet’rs’ Threshold Br. 11, and Central Iowa Power
    Cooperative v. FERC, 
    606 F.2d 1156
    (D.C. Cir. 1979), confirms
    that Section 202(a) precludes the Commission from requiring
    planning arrangements. Petitioners contend that “coordination”
    plainly encompasses transmission planning because “the
    coordination of transmission facilities is exactly what is done in
    transmission planning.” Pet’rs’ Threshold Br. 11. The statutory
    text, however, does not unambiguously establish the meaning of
    “coordination” that petitioners advance. As the Supreme Court
    has observed, “context matters,” Caraco 
    Pharm., 132 S. Ct. at 1681
    , and “‘[a] word is known by the company it keeps’—a rule
    that ‘is often wisely applied where a word is capable of many
    meanings in order to avoid the giving of unintended breadth to
    the Acts of Congress,’” Dolan v. U.S. Postal Serv., 
    546 U.S. 481
    , 486 (2006) (quoting Jarecki v. G.D. Searle & Co., 
    367 U.S. 303
    , 307 (1961)). The “coordination” addressed in Section
    202(a) is textually limited to coordination for purposes of
    generation, transmission and sale, all activities that require
    operating facilities. Section 202(a) is silent regarding the
    Commission’s authority with respect to pre-operational planning
    27
    designed as a remedy to practices affecting rates that are unjust,
    unreasonable, or unduly discriminatory or preferential; that
    authority is addressed in Section 206. Petitioners’ suggestion
    that “[r]eading ‘coordination’ to exclude coordinated
    transmission planning undermines the [FPA]’s purpose to
    preserve the voluntary nature of [commercial] relationships,”
    Pet’rs’ Threshold Br. 13, misperceives the nature of the Final
    Rule, which, as discussed, addresses process. By characterizing
    mandated transmission planning as mandating binding
    commercial relationships, petitioners’ approach fails for the
    same reasons their reliance on Otter Tail is unavailing.
    Central Iowa, 
    606 F.2d 1156
    , is not dispositive of the
    meaning of “coordination” in the context of planning for new
    transmission facilities. There, the court rejected challenges to
    the Commission’s approval, pursuant to Section 205, of a
    power-pooling agreement that “provide[d] a mechanism for
    coordinated daily operation of generation facilities” but did not
    establish a fully integrated electric system with central dispatch
    of generating units. 
    Id. at 1161.
    In addressing objections on
    antitrust grounds, the court observed that “Congress has decided,
    as a matter of general policy, that power pooling arrangements,
    rather than unrestrained competition between electric facilities,
    are in the public interest,” 
    id. at 1162,
    and that in enacting
    Section 202(a) “Congress was ‘confident that enlightened self-
    interest will lead the utilities to cooperate . . . in bringing about
    the economies which can alone be secured through . . . planned
    coordination.’” 
    Id. (quoting S.
    Rep. No. 74-621, at 49 (1935)).
    Although “Section 202(a) recognizes that power pooling can
    yield benefits of efficiency and economy,” nonetheless
    “Congress decided to make such coordination voluntary, with
    limited exceptions.” 
    Id. at 1167
    (emphasis added). Because of
    the “expressly voluntary nature of coordination under section
    202(a),” the court held that “the Commission could not have
    mandated adoption of the [power pooling] Agreement, and
    28
    failure . . . to establish a fully integrated electric system could
    not justify rejection of the Agreement filed.” 
    Id. at 1168
    (footnote omitted). The court acknowledged, however, that the
    Commission had authority under Section 206 “to order changes
    in the limited scope of the Agreement . . . if, in the absence of
    such modifications, the Agreement presented ‘any rule,
    regulation, practice or contract [that was] unjust, unreasonable,
    unduly discriminatory or preferential.” 
    Id. (alteration in
    original) (quoting 16 U.S.C. § 824e(a)). The court cautioned
    that “a pooling plan is [not] unlawful under section 206 merely
    because a more comprehensive arrangement might better
    achieve the purposes of section 202(a).” 
    Id. Petitioners maintain
    that Central Iowa “left no doubt that
    ‘coordination’ encompassed joint transmission planning”
    because the court “quot[ed] approvingly the definition found in
    [the Commission’s] own 1970 National Power Survey.” Pet’rs’
    Threshold Br. 9. That definition stated that “[a]s used in this
    chapter, [c]oordination is joint planning and operation of bulk
    power facilities by two or more electric systems for improved
    reliability and increased efficiency which would not be
    attainable if each system acted independently.” Central 
    Iowa, 606 F.2d at 1168
    n.36 (emphasis in original) (quoting FPC, The
    1970 National Power Survey I-17-1 to I-17-2 (1971)). The
    survey describes different degrees of power pooling among
    operating facilities, noting variables, including “managerial
    views with respect to planning, marketing, competition, and
    retention of prerogatives.” 
    Id. Neither the
    definition nor the
    description is inconsistent with the Commission’s interpretation
    of Section 202(a) in the Final Rule. The court, in any event, did
    not present the quotation as a definitive interpretation of the
    meaning of “coordination” as would bar the Commission’s
    adoption of planning reforms under Section 206. To the extent
    the court in Central Iowa interpreted Section 202(a) to mean that
    “Congress intended coordination and interconnection
    29
    arrangements be left to the ‘voluntary’ action of the utilities,”
    Atlantic 
    City, 295 F.3d at 12
    , there is nothing to suggest that the
    court purported to interpret the meaning of “coordination” in
    regard to the planning of future facilities. Petitioners’ view of
    Central Iowa thus fails to “trump[] [the Commission’s
    permissible] construction” of “coordination.” Nat’l Cable &
    Telecomms. Ass’n v. Brand X Internet Servs., 
    545 U.S. 967
    , 982
    (2005).
    Similarly, petitioners’ several grammatical objections to the
    Commission’s interpretation of Section 202(a) fail to
    demonstrate it is impermissible. Although the Commission
    acknowledged that “coordination,” viewed in isolation, might be
    read to include regional transmission planning, the Commission
    relied on other textual cues to conclude that “coordination”
    instead referred only to coordinated operation. Section 202(a)
    identified two activities that the Commission was to
    encourage — the “interconnection and coordination of
    facilities.” From the sequence of these terms, the Commission
    concluded that “coordination” referred to the coordination of
    operations that could occur only after facilities were
    interconnected. See Order No. 1000-A ¶¶ 123–25, 77 Fed. Reg.
    at 32,206. Petitioners suggest the Commission’s “artificial
    reliance on the sequence of the terms ‘interconnection’ and
    ‘coordination’ . . . creates an unnatural reading.” Pet’rs’
    Threshold Br. 13. Because “interconnection and coordination”
    are “phrased in the conjunctive,” petitioners conclude that there
    “is no logical or grammatical reason why the term coordination
    should be qualified by the term interconnection.” 
    Id. at 14.
    But
    reliance on the text and its structure to discern congressional
    intent is a well-recognized method of statutory interpretation.
    See, e.g., U.S. Nat’l Bank of Or. v. Indep. Ins. Agents of Am.,
    Inc., 
    508 U.S. 439
    , 455 (1993); see also ANTONIN SCALIA &
    BRYAN A. GARNER, READING LAW: THE INTERPRETATION OF
    LEGAL TEXTS 167 (2012). It is neither ungrammatical nor
    30
    unnatural to read “and” to suggest a chronological sequence.
    See DAVID CRYSTAL, THE CAMBRIDGE ENCYCLOPEDIA OF THE
    ENGLISH LANGUAGE 213 (1995); 2 GEORGE O. CURME, A
    GRAMMAR OF THE ENGLISH LANGUAGE: SYNTAX 162 (1980).
    “Nouns joined by coordinating conjunctions are usually treated
    as a single, compounded unit, and a postmodifying prepositional
    phrase is most naturally read to modify that single unit.”
    ConocoPhillips Co. v. EPA, 
    612 F.3d 822
    , 839 (5th Cir. 2010)
    (footnotes omitted) (citing SIDNEY GREENBAUM, OXFORD
    ENGLISH GRAMMAR 233 (1996)). Petitioners so fail to
    demonstrate that the Commission impermissibly construed
    “interconnection and coordination” as a single, sequential unit
    modified by the clause “of facilities for the generation,
    transmission, and sale of electric energy.” Petitioners likewise
    fail to show that the Commission impermissibly construed
    Section 202(a) to refer only to currently operating facilities; the
    post-modifying prepositional phrase contains only operational
    nouns (“generation, transmission, and sale”), as opposed to pre-
    operational nouns (e.g., “planning,” “development,” or
    “construction”).
    Neither do petitioners demonstrate that the Commission’s
    interpretation of Section 202(a) was arbitrary and capricious
    because it departed from a prior interpretation without
    explanation. Pointing to the Commission’s references to
    “coordination” in other contexts, they show no “flip flop,”
    Pet’rs’ Threshold Br. 16, requiring further explanation by the
    Commission. For example, the Commission’s statement that
    “[l]ong-range planning is an indispensable element to the
    accomplishment of the objective of Section 202(a),” Order No.
    383-4, Reliability and Adequacy of Electric Service Reporting
    Data, 56 F.P.C. 3547, 3548 (1976), is not inconsistent with
    interpreting Section 202(a) to refer to operating facilities. The
    Commission’s statement in Public Service Co. of Indiana, 59
    F.P.C. 1351, 1355 (1977), that “[t]he importance of encouraging
    31
    coordinated planning and operation of bulk power supply
    systems has been a cornerstone of Commission policy for many
    years,” refers to a package of activities and was not addressing
    whether mandated pre-operational transmission planning is
    barred by Section 202(a). Neither did the Commission
    determine in Mid-Continent Area Power Pool Agreement, 58
    F.P.C. 2622 (1977), “that directing joint transmission planning
    was beyond its authority,” Pet’rs’ Threshold Br. 16–17; instead
    the Commission found that a lack of single-system planning was
    not unjust, unreasonable, or unduly discriminatory, see 58 F.P.C.
    at 2637.
    C.
    Petitioners contend that even if Section 206 does not bar the
    Commission from mandating regional transmission planning,
    FPA Section 201(a) does. Section 201(a) authorizes the
    Commission to regulate “transmission of electric energy in
    interstate commerce” but also provides that this authority
    “extend[s] only to those matters which are not subject to
    regulation by the States.” 16 U.S.C. § 824(a). Petitioners assert
    that the mandate infringes on the States’ traditional regulation
    of transmission planning, siting, and construction, violating the
    federalism principle recognized in Section 201(a). We disagree.
    Petitioners’ contention that the challenged orders intrude on
    the States’ traditional role in regulating siting and construction
    requires little discussion. Even assuming arguendo that siting
    and construction are matters “subject to regulation by the States”
    within the meaning of Section 201(a), petitioners’ contention
    simply cannot be squared with the language of the orders, which
    expressly and repeatedly disclaim authority over those matters.
    See, e.g., Order No. 1000 ¶¶ 107, 156, 227, 253 n.231, 257, 259,
    287, 337, 339, 76 Fed. Reg. at 49,861, 49,869, 49,880,
    49,885–87, 49,891, 49,899–900; Order No. 1000-A ¶¶ 105,
    186–94, 377–79, 77 Fed. Reg. at 32,203, 32,215–16, 32,243–44.
    32
    The orders neither require facility construction nor allow a party
    to build without securing necessary state approvals. See Order
    No. 1000 ¶¶ 66, 159, 227, 76 Fed. Reg. at 49,854, 49,870,
    49,880; Order No. 1000-A ¶¶ 186–91, 377–79, 77 Fed. Reg. at
    32,215–16, 32,243–44.
    Petitioners’ argument that the orders interfere with state
    regulation of planning, however, poses a closer question.
    Petitioners correctly contend that the Commission used the
    challenged orders to further regulate the transmission planning
    process. And, petitioners maintain, because state regulators
    were already substantially involved in regulating that process,3
    the orders encroach on their authority in violation of Section
    201(a)’s statement that the Commission’s authority “extend[s]
    only to those matters which are not subject to regulation by the
    States.” 16 U.S.C. § 824(a). But while petitioners’ argument is
    not without force, relevant precedent suggests that Section
    201(a) does not stand in the way of the orders’ planning
    mandate.
    In New York v. FERC, 
    535 U.S. 1
    , the Court rejected a
    state’s argument that Section 201(a) barred the Commission
    from ordering certain utilities to “transmit competitors’
    electricity over [their] lines on the same terms that the utilit[ies]
    applie[d] to [their] own energy transmissions.” 
    Id. at 4–5,
    20–24. The Court’s substantial discussion of Section 201 yields
    several insights into the provision’s meaning that are helpful in
    resolving petitioners’ argument.
    3
    For example, the Florida Public Service Commission is
    statutorily vested with authority to “plan[], develop[], and
    main[tain] . . . a coordinated electric power grid” throughout the state.
    FLA. STAT. § 366.04(5); see also Joint Br. of State Pet’rs’ 20–22
    (citing state statutes related to planning).
    33
    First, the Commission possesses greater authority over
    electricity transmission than it does over sales. See 
    id. at 17,
    19–20. Even though Section 201(b) does “limit FERC’s sale
    jurisdiction to that at wholesale,” there is no textual warrant for
    the suggestion that the Commission lacks jurisdiction over retail
    transmission. 
    Id. at 17.
    That is, the FPA preserves for the States
    relatively more sales authority than transmission authority.
    Second, Section 201(a)’s reference to a sphere of state
    authority is “a mere policy declaration” that should not be read
    in derogation of other specific provisions granting the
    Commission authority, including Section 201(b)’s grant of
    authority over “transmission of electric energy in interstate
    commerce.” 
    Id. at 17,
    22 (internal quotation marks omitted).
    As long as the Commission’s activity falls within one of these
    specific jurisdictional grants, the “prefatory language of section
    201(a)” does “not undermine FERC’s jurisdiction.” 
    Id. at 22.
    And the authority that Section 201(b) affords to the Commission
    has expanded over time because transmissions on the
    interconnected grids that have now developed “constitute
    transmissions in interstate commerce.” 
    Id. at 7,
    16.
    Taken together, these points support the Commission’s
    assertion of authority over transmission planning matters in the
    challenged orders, notwithstanding petitioners’ contention that
    the orders intrude on the States’ authority. First, because the
    planning mandate relates wholly to electricity transmission, as
    opposed to electricity sales, it involves a subject matter over
    which the Commission has relatively broader authority.4
    Second, because the orders’ planning mandate is directed at
    4
    This fact distinguishes this case from Electric Power Supply
    Ass’n v. FERC, 
    753 F.3d 216
    (D.C. Cir. 2014), a case cited by
    petitioners where this court struck down a Commission attempt to
    regulate an aspect of retail electricity sales. 
    Id. at 218.
                                     34
    ensuring the proper functioning of the interconnected grid
    spanning state lines, cf. Duke Power Co. v. FPC, 
    401 F.2d 930
    ,
    935 (D.C. Cir. 1968) (explaining that the “major emphasis” of
    the FPA “is upon federal regulation of those aspects of the
    industry which—for reasons either legal or practical—are
    beyond the pale of effective state supervision”), the mandate fits
    comfortably within Section 201(b)’s grant of jurisdiction over
    “the transmission of electric energy in interstate commerce.” Cf.
    New York v. 
    FERC, 535 U.S. at 15
    (recognizing that the Court
    has “construed broadly” the grant of jurisdiction in Section 201);
    United States v. Pub. Utils. Comm’n of Cal., 
    345 U.S. 295
    , 299
    (1953) (recognizing that federal authority under the FPA extends
    to the “transmission of electric energy in interstate commerce”
    and that FPA Section 206 is among those provisions that grant
    “authority in connection with such interstate transmission
    operations”). Given that fit, New York v. FERC teaches that
    there is no reason to think that the “prefatory” statement of
    federalism “policy” in Section 201(a) poses an obstacle to the
    Commission’s assertion of authority. 
    See 535 U.S. at 17
    , 22.
    Accordingly, we reject petitioners’ challenge because Section
    201 does not preclude the Commission’s regulation of
    transmission planning in the Final Rule.
    Because we hold that the Final Rule does not interfere with
    the traditional state authority that is preserved by Section 201,
    and that the Commission permissibly interpreted “coordination”
    in Section 202(a) to refer to existing facilities, we turn in Part III
    to petitioners’ contention that the Commission failed to meet its
    evidentiary burden under Section 206.
    III.
    “Theoretical Threat” as a Basis for Section 206
    Rulemaking. The Commission concluded that “the narrow
    focus of current planning requirements and shortcomings of
    35
    current cost allocation practices create an environment that fails
    to promote the more efficient and cost-effective development of
    new transmission facilities, and that addressing these issues is
    necessary to ensure just and reasonable rates.” Order No. 1000
    ¶ 52, 76 Fed. Reg. at 49,852. It described the problem to be
    remedied as a “theoretical threat” that was “significant enough
    to justify the requirement[s] imposed by th[e] Final Rule.” 
    Id. (citing Nat’l
    Fuel Gas Supply Corp. v. FERC, 
    468 F.3d 831
    (D.C. Cir. 2006)). The Commission concluded that the threat
    “stem[med] from the absence of planning processes that take a
    sufficiently broad view of both the tasks involved and the means
    of addressing them.” 
    Id. Although maintaining
    that the “actual
    experiences of problems cited in the record . . . provide
    additional support for [its] action,” the Commission stated its
    remedy was “justified sufficiently by the ‘theoretical threat.’”
    
    Id. ¶ 53,
    76 Fed. Reg. at 49,852–53; see Order No. 1000-A ¶ 57,
    77 Fed. Reg. at 32,195.
    Petitioners contend that the “theoretical threat” described by
    the Commission fails to satisfy its evidentiary burden under
    Section 206, and therefore the Final Rule does not constitute
    reasoned decisionmaking. They also contend the Commission
    failed to give reasoned consideration to objections that the Final
    Rule violates FPA Section 217(b)(4), 16 U.S.C. § 824q(b)(4),
    which requires the Commission to facilitate the planning and
    expansion of transmission to meet the needs of load-serving
    entities. Neither contention withstands analysis.
    A.
    Petitioners maintain both that the Commission relied solely
    upon speculation to conclude existing transmission planning
    practices were deficient, and that the Commission is improperly
    seeking to optimize already just and reasonable planning
    practices. Similarly, they maintain that the Commission relied
    on speculation in concluding the remedies imposed by the Final
    36
    Rule will be economically beneficial. In petitioners’ view, the
    Commission has not met the “high bar” identified in National
    Fuel for agency action “based solely on theory” because it has
    failed to explain why evidence of abuse is undetectable, why the
    cost of the Final Rule is justified, and why case-specific
    resolution is not feasible. See Pet’rs’ Threshold Br. 28 (citing
    National 
    Fuel, 468 F.3d at 844
    –45). Petitioners have
    misconceived the nature of the Commission’s evidentiary
    burden.
    To regulate a practice affecting rates pursuant to Section
    206, the Commission must find that the existing practice is
    “unjust, unreasonable, unduly discriminatory or preferential,”
    and that the remedial practice it imposes is “just and
    reasonable.” 16 U.S.C. § 824e(a). These findings must be
    supported by “substantial evidence,” 5 U.S.C. § 706(2)(E),
    which the court has long held does not necessarily mean
    empirical evidence. Where the “[p]romulgation of generic rate
    criteria clearly involves the determination of policy goals or
    objectives, and the selection of means to achieve them,” the
    “[c]ourts reviewing an agency’s selection of means are not
    entitled to insist on empirical data for every proposition on
    which the selection depends.” Associated Gas 
    Distributors, 824 F.2d at 1008
    . So long as a prediction is “at least likely enough
    to be within the Commission’s authority” and it is based on
    reasonable economic propositions, the court will uphold it. 
    Id. “Agencies do
    not need to conduct experiments in order to rely
    on the prediction that an unsupported stone will fall; nor need
    they do so for predictions that competition will normally lead to
    lower prices.”

    1. Prior to Order No. 1000, the deficiencies in transmission
    planning and cost allocation practices were well-understood and
    not based on guesswork, as petitioners claim. For example, the
    Commission addressed the dangers posed by inadequate
    planning in Order No. 888 when it encouraged transmission
    providers to form RTOs and ISOs. 
    See supra
    Part I. Growth in
    demand without growth in transmission investment led to the
    Commission’s adoption of the transmission planning reforms in
    Order No. 890. These reforms addressed congestion as well as
    the lack of specificity regarding how customers and other
    stakeholders should be treated in the transmission planning
    process. See id.; Order No. 890 ¶¶ 422–25, 72 Fed. Reg. at
    12,318.      Industry consultants thereafter projected that
    considerable expansion of the electric transmission grid was
    likely to occur between 2010 and 2030. 
    See supra
    Part I. The
    Department of Energy reached a similar conclusion. See 
    id. At the
    Commission’s 2009 technical conferences, participants
    confirmed problems with existing and non-existing regional
    planning and cost allocation practices in the electric industry.
    See, e.g., Ron Lehr of Am. Wind Energy Assoc. on behalf of
    Interwest Energy Alliance & W. Grid Grp. (Sep. 3, 2009
    Technical Conference in Phoenix, AZ) (commenting on
    difficulty, absent regional planning, of renewable suppliers
    entering the planning process to challenge incumbents); Steve
    Gaw, Policy Dir., Wind Coalition (Sept. 10, 2009 Technical
    Conference in Atlanta, GA) (opening remarks identifying
    significant cost implications of the lack of a policy on
    interregional cost allocation).
    Comments during the rulemaking, including comments
    from the regulated industry, referred to similar problems. For
    example, industry economists at The Brattle Group “identified
    approximately 130 mostly conceptual and often overlapping
    planned transmission projects,” with a total cost of over $180
    38
    billion, and concluded that “a large portion of these projects will
    not be built due to overlaps and deficiencies in transmission
    planning and cost allocation processes.” Order No. 1000 ¶ 38,
    76 Fed. Reg. at 49,850. Other commenters agreed that existing
    transmission planning and cost allocation practices were
    deficient and “provide[d] specific examples of
    developments . . . demonstrat[ing] the need for reform.” 
    Id. ¶¶ 32–37,
    76 Fed. Reg. at 49,849–50 (summarizing comments
    from, inter alia, Colorado Independent Energy Association and
    Iberdrola Renewables). The Commission rejected comments
    characterizing factual examples as “anecdotal,” emphasizing
    that “[a] wide range of concerns have been raised by
    commenters,” who “have experienced unjust and unreasonable,
    or unduly discriminatory or preferential practices in the
    transmission planning aspects of the transmission service
    provided by public utility transmission providers.” 
    Id. ¶¶ 50,
    58,
    76 Fed. Reg. at 49,852–53.
    The threat to just and reasonable rates arose, in the
    Commission’s judgment, from existing planning and cost
    allocation practices that could thwart the identification of more
    efficient and cost-effective transmission solutions. In proposing
    reforms to the planning requirements of Order No. 890, the
    Commission identified “significant changes in the nation’s
    electric power industry,” including the proliferation of
    renewable energy resources whose viability depended upon the
    development of new transmission facilities. NPRM ¶¶ 33 &
    n.41, 150–53, 75 Fed. Reg. at 37,889, 37,904. These changes
    presented “significant challenges” to the development and cost
    allocation of interstate transmission projects. 
    Id. ¶¶ 33–34
    &
    n.41, 152–54, 75 Fed. Reg. at 37,889, 37,904. They also
    highlighted deficiencies in Order No. 890’s transmission
    planning and cost allocation processes, which the Commission
    identified as: (1) the lack of a requirement for a regional
    transmission plan, (2) the failure of current transmission
    39
    planning processes to account for transmission needs driven by
    public policy requirements (e.g., State renewable energy
    standards), (3) the failure to address obstacles to non-incumbent
    transmission project developers’ participation in regional
    transmission planning processes, (4) the relative lack of
    coordination between transmission planning regions, and (5) the
    lack of rate structures that provide for the allocation and
    recovery of costs for transmission projects located either within
    a non-RTO transmission planning region or in more than one
    transmission planning region. See 
    id. ¶¶ 35–41,
    75 Fed. Reg. at
    37,889–90.
    Additionally, the recent increase in transmission investment
    reported by the Edison Electric Institute and NERC indicated the
    need “to ensure that . . . transmission planning and cost
    allocation requirements are adequate to support more efficient
    and cost-effective investment decisions moving forward.” Order
    No. 1000 ¶ 44, 76 Fed. Reg. at 49,851. Industry also had
    reported a longer-term period of investment in new transmission
    facilities was on the horizon, driven “in large part” by “changes
    in the mix of generation resources” as a result of increasing
    reliance on natural gas and large-scale renewable generation.
    See 
    id. ¶¶ 44–45,
    76 Fed. Reg. at 49,851 (collecting sources).
    The Commission noted that “[t]ransmission planning is a
    complex process that requires consideration of a broad range of
    factors” and that “the development of transmission facilities can
    involve long lead times and complex problems.” 
    Id. ¶ 50,
    76
    Fed. Reg. at 49,852. Under the circumstances, the Commission
    concluded that the threat to just and reasonable rates was acute.
    See 
    id. ¶¶ 43–46,
    76 Fed. Reg. at 49,851.
    2. Yet petitioners contend that a nationwide rulemaking
    was not appropriate.       Initially they suggest that the
    Commission’s statement in issuing Order No. 1000 that
    “transmission planning processes have seen substantial
    40
    improvements” since Order No 890 was issued, Order No. 1000
    ¶ 43, 76 Fed. Reg. at 49,851, was an acknowledgment that
    “existing voluntary planning processes work quite well,” Pet’rs’
    Threshold Br. 22, and no reform is needed. Current
    transmission planning practices, they maintain, “cannot be
    unreasonable simply because they may not produce an optimal
    outcome” or “some alternative might produce a better or ‘more
    efficient’ outcome.” 
    Id. at 23
    (emphasis in original). Petitioners
    also contend that the Commission “largely ignored evidence of
    existing, successful planning processes” in some parts of the
    country, such as the Southeast. 
    Id. at 28.
    Neither contention is
    persuasive.
    As discussed, the Commission explained why existing
    transmission planning and cost allocation practices were
    inadequate. Order No. 890, for example, did not require
    transmission providers to “identify and evaluate transmission
    alternatives at the regional level that may resolve the region’s
    needs more efficiently or cost-effectively than solutions
    identified in the local transmission plans of individual public
    utility transmission providers.” Order No. 1000 ¶ 78, 76 Fed.
    Reg. at 49,856. Without “a robust process [] in place to identify
    and consider regional solutions to regional needs,” 
    id. ¶ 320,
    76
    Fed. Reg. at 49,897, the Commission concluded that some
    transmission providers were merely “confirm[ing] the
    simultaneous feasibility of transmission facilities contained in
    their local transmission plans” and overlooking more efficient
    or cost-effective regional transmission alternatives, 
    id. ¶¶ 78–80,
    320, 76 Fed. Reg. at 49,856–57, 49,897.
    Furthermore, in deciding to proceed by a nationwide rule
    rather than case-by-case adjudication, the Commission did not
    ignore that “some current practices in some regions” may have
    already been satisfying “a minimum set of requirements that
    must be met” under the Final Rule. Order No. 1000-A ¶ 66, 77
    41
    Fed. Reg. at 32,196. Rather, it understood that “the present is
    not a prediction of the future” and emphasized that “all of these
    requirements are not satisfied in all regions.” 
    Id. ¶¶ 65–66,
    77
    Fed. Reg. at 32,196. Although recognizing that concerns driving
    the need for reforms “may not affect each region of the country
    equally,” the Commission stated it “remain[ed] concerned” that
    the requirements under Order No. 890 “are inadequate to ensure
    the development of more efficient and cost-effective
    transmission.” Order No. 1000 ¶ 60, 76 Fed. Reg. at 49,853.
    Based on its expertise and experience, the Commission’s
    determination that the current planning and cost allocation
    practices were unjust or unreasonable “warrants substantial
    deference from this court.” Cities of Bethany v. FERC, 
    727 F.2d 1131
    , 1137 (D.C. Cir. 1984). “[T]he Commission may rely on
    ‘generic’ or ‘general’ findings of a systemic problem to support
    imposition of an industry-wide solution.” Interstate Natural
    
    Gas, 285 F.3d at 37
    (citing 
    TAPS, 225 F.3d at 687
    –88, and
    Wisconsin 
    Gas, 770 F.2d at 1166
    & n.36). Its acknowledgment
    of relative improvement since Order No. 890 did not
    demonstrate that the Commission abused its discretion in
    deciding to proceed by rulemaking, having concluded that
    “existing transmission planning processes are unjust and
    unreasonable or unduly discriminatory or preferential.” Order
    No. 1000 ¶ 116, 76 Fed. Reg. at 49,862. That some commenters
    may engage in sufficient transmission planning processes “is as
    unastonishing as it is irrelevant,” Wisconsin 
    Gas, 770 F.2d at 1157
    , because petitioners have not shown that the deficiencies
    identified by the Commission “exist[] only in isolated pockets,”
    Associated Gas 
    Distributors, 824 F.2d at 1019
    . Absent such an
    extreme “disproportion of remedy to ailment,” the Commission
    could reasonably proceed to address a systemic problem with an
    industry-wide solution. Id.; see also Interstate Natural 
    Gas, 285 F.3d at 37
    –38; infra Part III.C.
    42
    B.
    No more persuasive is petitioners’ position that, absent
    empirical evidence of planning abuses, the Commission relied
    only on speculation to conclude that the reforms required by the
    Final Rule are just and reasonable. Petitioners point in
    particular to the Commission statements that its planning and
    cost allocation reforms “might,” “may,” or “could” improve
    outcomes. E.g., Order No. 1000 ¶¶ 6, 47, 81, 148, 76 Fed. Reg.
    at 49,845, 49,852, 49,857, 49,868. Citing Algonquin Gas
    Transmission Co. v. FERC, 
    948 F.2d 1305
    , 1313–14 (D.C. Cir.
    1991), petitioners contend that the use of such conditional words
    shows that “there is no underlying theory at all, only conjecture
    about how utility practices might change for the better if [the
    Final Rule’s] mandates are adopted.” Pet’rs’ Threshold Br.
    24–25.
    The Commission’s reticence to make definitive claims
    about the future does not make its determination legally
    deficient because “a forecast of the direction in which future
    public interest lies necessarily involves deductions based on the
    expert knowledge of the agency.” Transcontinental 
    Gas, 365 U.S. at 29
    . The Commission explained that its use of such
    words must be understood in context: “When making a generic
    factual prediction, one is not predicting what will occur with
    certainty in every instance but rather what it is reasonable to
    conclude will occur with sufficient frequency and to a sufficient
    degree to conclude that the reforms are needed.” Order No.
    1000-A ¶ 73, 77 Fed. Reg. at 32,197. Although qualified
    statements, like economic models, “do not always have the
    reassuring concreteness of empirical observations,” Am. Pub.
    
    Gas, 567 F.2d at 1037
    , the Commission, as was true in
    Associated Gas 
    Distributors, 824 F.2d at 1008
    –09, based its
    remedial findings on “well-established general principles” — for
    example, that competition will normally lead to lower prices.
    See Order No. 1000-A ¶ 70, 77 Fed. Reg. at 32,197; see also 
    id. 43 ¶
    60, 77 Fed. Reg. at 32,195. The analysis by The Brattle Group
    confirms that it required no speculation by the Commission to
    conclude, “based on [its] expertise and knowledge of the
    industry, . . . that regional transmission planning is more
    effective if it results in a transmission plan, is open and
    transparent, and considers all transmission needs.” 
    Id. ¶ 60,
    77
    Fed. Reg. at 32,195. Similarly, the Commission’s predictive
    judgment that “the presence of multiple transmission developers
    would lower costs to customers,” Order No. 1000 ¶ 268, 76 Fed.
    Reg. at 49,888 (internal quotation marks omitted), was
    permissibly grounded in basic economic principles. As the
    Commission observed, petitioners’ reference to “unsupported
    assertion[s],” Algonquin 
    Gas, 948 F.2d at 1313
    , “confuse[s] a
    theoretical threat, [which is] a potential threat that has not yet
    materialized, with a theory used in an academic discipline,
    [which is] an area of activity that is not comparable to the tasks
    or responsibilities entrusted to a regulatory agency.” Order No.
    1000-A ¶ 70, 77 Fed. Reg. at 32,197. See generally Sacramento
    Mun. Util. Dist. v. FERC, 
    616 F.3d 520
    , 530–31 (D.C. Cir.
    2010).
    Petitioners maintain as well that the Commission’s
    underlying theory is “significant[ly] flaw[ed]” because its
    finding that competition in the electricity transmission market
    will be beneficial fails to recognize that electric transmission is
    a natural monopoly. Pet’rs’ Threshold Br. 31–32. They suggest
    there would be no construction of competing transmission
    systems and firms would not compete by charging lower prices
    to consumers. Yet this misconceives the basis for the
    competitive benefits predicted by the Commission. The leading
    antitrust treatise, on which petitioners rely, instructs that
    “competition for a natural monopoly can be just as beneficial to
    consumers as competition within an ordinary market.” III

    44
    ANTITRUST POLICY: THE LAW OF COMPETITION AND ITS
    PRACTICE 34 (4th ed. 2011). Known as the theory of contestable
    markets, the principle states that even in a naturally
    monopolistic market the threat of competitive entry (e.g.,
    through competitive bidding) will lead firms to lower their costs,
    which thereby generally lowers cost-based utility rates. See
    generally HOVENKAMP, FEDERAL ANTITRUST POLICY at 34;
    Harold Demsetz, Why Regulate Utilities?, 11 J.L. & Econ. 55
    (1968). For example, the comments of LS Power Transmission,
    LLC (“LS Power”), a non-incumbent transmission developer,
    provided specific examples of non-incumbent developers
    submitting substantially lower cost estimates for transmission
    projects than incumbents: In the Texas Competitive Renewable
    Energy Zone program, “some entities attempted to distinguish
    themselves through return on equity concessions or other rate-
    related proposals,” including one proposal estimated to save
    customers 8–10% annually compared to incumbent provider
    rates. Reply Comments of LS Power Transmission, LLC at 24
    n.80 (Nov. 12, 2010). LS Power’s own experience in proposing
    a transmission project in the Midwest ISO region was that its
    per-mile estimated cost was nearly half that of the incumbent
    developer’s. See Comments of LS Power Transmission, LLC at
    7–9 & n.15 (Nov. 23, 2009).
    Because petitioners point to no “inexplicable distortion” in
    the competition theory that would render the Commission’s
    determination arbitrary and capricious, see Associated Gas
    
    Distributors, 824 F.2d at 1008
    (citing Elec. Consumers Res.
    Council v. FERC, 
    747 F.2d 1511
    , 1514 (D.C. Cir. 1984)), the
    court appropriately defers to the Commission’s expertise and
    experience, and holds that the Commission has met its burden to
    support the remedies in the Final Rule with substantial evidence.
    C.
    45
    Petitioners’ reliance on National Fuel, 
    468 F.3d 831
    , is
    misplaced. There, the Commission had sought to expand
    standards of conduct based on a “theoretical threat of undue
    preferences and a claimed record of abuse,” 
    id. at 839
    (emphasis
    added), but failed to cite a single example of abuse by the parties
    to whom the extended standards would apply, 
    id. at 841.
    Having failed to support both grounds on which it had purported
    to act, the Commission failed, the court held, to meet the
    substantial evidence test. See 
    id. at 843–44.
    In remanding the
    case, the court volunteered “guidance” in the event that the
    Commission decided to proceed solely on the basis of a
    “theoretical threat.” 
    Id. at 844.
    Petitioners here contend that the
    Commission failed to meet National Fuel’s “high bar” in
    promulgating the Final Rule. Pet’rs’ Threshold Br 28.
    The “guidance” in National Fuel did not purport to establish
    a generally applicable standard for agency regulation based on
    a “theoretical threat.” Rather, it was designed to “merely
    illustrate the kind of analysis” the Commission might undertake
    on remand. National 
    Fuel, 468 F.3d at 845
    . But even were the
    court to assume that the three-part guidance applied, the
    Commission met that burden. First, petitioners misread
    National Fuel as requiring the Commission to “explain why
    evidence of abuse is undetectable.” Pet’rs’ Threshold Br. 28.
    All the court said was that “[i]f [the Commission] believes that
    the nature of the alleged misconduct renders it undetectable,”
    then the Commission “would have to say, for example, why
    such evidence of abuse was detected [earlier].” National 
    Fuel, 468 F.3d at 844
    . The Commission made no such claim here; it
    identified the conduct that led it to conclude the requirements of
    Order No. 890 were inadequate to meet current and future
    challenges in the electric transmission industry. 
    See supra
    Part
    III.A.
    46
    Second, the Commission reasonably balanced the costs
    stemming from deficient transmission planning and cost
    allocation practices against the growth in demand for
    transmission service, concluding that the public interest in just
    and reasonable electricity rates outweighed claimed burdens and
    warranted implementing the reforms now. See Order No. 1000-
    A ¶¶ 91–94, 77 Fed. Reg. at 32,200–01. The Brattle Group’s
    report was but one example of record evidence documenting the
    costs of inefficient and irregular planning. Industry projections,
    and the reasons therefor, established the likelihood of huge
    growth in demand for electric service. The Commission
    concluded that the required reforms “will promote considerable
    economic benefits in the form of lower congestion, greater
    reliability, and greater access to generation resources.” 
    Id. ¶ 586,
    77 Fed. Reg. at 32,275. It also concluded that it was
    “prudent” to act now rather than “wait for systemic problems to
    undermine transmission planning.” Order No. 1000 ¶ 50, 76
    Fed. Reg. at 49,852. Further, while acknowledging that the
    mandated transmission planning process, like most high-stakes
    processes, may engender some disagreements or conflicts, 
    id. ¶ 330,
    76 Fed. Reg. at 49,898, the Commission encouraged
    transmission providers to consider ways to minimize disputes
    (e.g., through additional transparency mechanisms). 
    Id. And it
    anticipated that some reforms, particularly to cost allocation
    practices, would reduce conflicts and “aid in the development
    and construction of new transmission, as stakeholders will be
    able to see clearly who is benefitting from, and subsequently
    who has to pay for, the transmission investment.” 
    Id. ¶ 669,
    76
    Fed. Reg. at 49,943. Through these reforms, then, stakeholders
    will “necessarily” determine ex ante “that the benefits associated
    with [a particular] set of transmission facilities outweigh the
    costs.” 
    Id. ¶ 499,
    76 Fed. Reg. at 49,921.
    Petitioners err in suggesting that the Commission ignored
    the loss of efficiencies caused by undermining vertical
    47
    integration, see Pet’rs’ Threshold Br. 34–37, which “occurs
    when a firm provides for itself some input that it might
    otherwise purchase on the market.”              IIIB AREEDA &
    HOVENKAMP ¶ 755a. The Commission acknowledged the
    potential efficiencies of vertical integration but concluded they
    provided “no basis for claiming that vertical integration requires
    the exclusion of nonincumbent transmission developers.” Order
    No. 1000-A ¶ 90, 77 Fed. Reg. at 32,200. The Commission
    observed it “would expect that vertically-integrated public
    utilities will be well positioned to compete in a transmission
    development process that is open to nonincumbent transmission
    developers.” 
    Id. Petitioners not
    only mischaracterize the
    Commission’s response as an attempt to shift the burden on
    incumbent providers to justify maintaining vertical integration,
    see Pet’rs’ Threshold Reply Br. 3, 18–19, their reliance on
    authority dealing with “vertical integration between a [natural
    gas] pipeline and its affiliates,” National 
    Fuel, 468 F.3d at 840
    (emphasis added), is misplaced, see Pet’rs’ Threshold Br. 34.
    Based on its experience and expertise, the Commission
    anticipated that natural market forces would indicate whether
    vertical integration provides any net competitive advantage in
    the context of transmission development. See Order No. 1000-A
    ¶ 90, 77 Fed. Reg. at 32,200. Petitioners offer no basis for
    concluding that the Commission’s judgment regarding the role
    that vertical integration will play in a competitive transmission
    planning process is arbitrary and capricious. On rehearing the
    Commission also observed that “[t]he existence of vertical
    integration does not imply that the vertically integrated public
    utility must be a monopoly.” Order No. 1000-A ¶ 90, 77 Fed.
    Reg. at 32,200; see IIIB AREEDA & HOVENKAMP ¶ 759e5.
    Petitioners’ response that the Commission’s analysis “has
    conflated the concepts of monopoly and vertical integration,”
    Pet’rs’ Threshold Br. 36, is ipse dixit contradicted by the Areeda
    treatise upon which it relies.
    48
    Third, the Commission explained that the problem it was
    addressing was “systemic,” Order No. 1000 ¶ 50, 76 Fed. Reg.
    at 49,852, and “not one that can be addressed adequately or
    efficiently through the adjudication of individual complaints,”
    which “by their nature focus on discrete questions of a specific
    case,”id. ¶ 52, 76 Fed. Reg. at 49,852. In the Commission’s
    judgment, “[r]ules setting forth general principles are necessary
    to ensure that adequate planning processes are in place.” 
    Id. “[T]he decision
    whether to proceed by rulemaking or
    adjudication lies within the broad discretion of the agency,” and
    deference to the Commission’s decision here is “particularly
    appropriate” because “‘the breadth and complexity of the
    Commission’s responsibilities demand that it be given every
    reasonable opportunity to formulate methods of regulation
    appropriate for the solution of its intensely practical
    difficulties.’” Wisconsin 
    Gas, 770 F.2d at 1166
    (quoting
    Permian Basin Area Rate 
    Cases, 390 U.S. at 790
    ) (citing SEC
    v. Chenery Corp., 
    332 U.S. 194
    , 202–03 (1947)).
    Finally, petitioners’ reliance on FPA Section 217(b)(4) is
    also misplaced. That provision, in pertinent part, requires the
    Commission to exercise its authority “in a manner that facilitates
    the planning and expansion of transmission facilities to meet the
    reasonable needs of load-serving entities to satisfy the[ir]
    service obligations.” 16 U.S.C. § 824q(b)(4). Petitioners
    maintain “[i]t is implausible to characterize load serving
    entities’ loss of control over the development of needed facilities
    as ‘facilitating’ their ability to plan and expand the transmission
    system.” Pet’rs’ Threshold Br. 40–41. The Commission
    determined, however, that “[g]reater participation by
    transmission developers in the transmission planning process
    may lower the cost of new transmission facilities, enabling more
    efficient or cost-effective deliveries by load serving entities and
    increased access to resources.” Order No. 1000 ¶ 291, 76 Fed.
    Reg. at 49,892; see Order No. 1000-A ¶ 178, 77 Fed. Reg. at
    49
    32,213–14. Petitioners offer no basis to reject the Commission’s
    conclusion that the Final Rule “supports the development of
    needed transmission facilities, which ultimately benefits load-
    serving entities,” and that “serv[ing] the interests of other
    stakeholders . . . does not place [the Final Rule] in conflict with
    section 217.” Order No. 1000 ¶ 108, 76 Fed. Reg. at 49,861; see
    also infra Part VI.B.
    IV.
    Removal of Federal Rights of First Refusal. In addition
    to attacking the transmission planning mandate generally,
    petitioners raise a host of challenges to the requirement that
    public utilities remove certain rights of first refusal from their
    tariffs and agreements.5 See Order No. 1000 ¶¶ 67, 225, 76 Fed.
    Reg. at 49,854, 49,880. We conclude that the removal mandate
    is a legitimate exercise of the Commission’s authority and reject
    petitioners’ arguments.
    A.
    Prior to the removal mandate, utilities’ tariffs and
    agreements routinely included rights of first refusal. These
    rights gave incumbent utilities the option to construct any new
    transmission facilities in their particular service areas, even if
    the proposal for new construction came from a third party. In
    practice, incumbents were likely to exercise their rights of first
    refusal once the benefits of a new project were demonstrated.
    In this way, rights of first refusal discouraged non-incumbents
    5
    Under the FPA, a tariff is the mechanism through which a
    regulated utility sets its rates unilaterally. See NRG Power Mktg., LLC
    v. Me. Pub. Utils. Comm’n, 
    558 U.S. 165
    , 171 (2010). Rates may also
    be set by agreement between utilities and power purchasers. See 
    id. 50 from
    proposing transmission facilities.6 Not only would non-
    incumbents be unlikely to recoup the full benefits of their
    proposal, but they would not even be able to recoup the costs of
    identifying the need and making a proposal that would address
    it. 
    Id. ¶¶ 256–57,
    76 Fed. Reg. at 49,886.
    The Commission feared that this lack of an incentive for
    non-incumbents to propose needed infrastructure would
    ultimately give rise to unlawful rates for customers. By
    deterring proposals from non-incumbents, rights of first refusal
    would impede the identification of some cost-efficient projects,
    resulting in the development of transmission facilities “at a
    higher cost than necessary.” 
    Id. ¶¶ 228–30,
    76 Fed. Reg. at
    49,880–81. Those higher costs would then be passed on to
    customers, yielding rates that were “not just and reasonable,”
    
    id., in violation
    of the FPA. The Commission’s concerns were
    particularly acute in light of its expectation that a massive
    amount of transmission facility development would take place
    during the next two decades as renewable energy sources were
    integrated into the grid. See 
    id. ¶¶ 29,
    44–47, 76 Fed. Reg. at
    49,849, 49,851–52.
    To address this problem created by rights of first refusal, the
    Commission proposed requiring their elimination. NPRM ¶ 89,
    75 Fed. Reg. at 37,896. The Federal Trade Commission
    submitted comments supporting the Commission’s proposal,
    observing that rights of first refusal reduce investment
    6
    As explained in Part I, an “incumbent” transmission provider
    is “an entity that develops a transmission project within its own retail
    distribution service territory or footprint.” Order No. 1000 ¶225, 76
    Fed. Reg. at 49,880. By contrast, a “non-incumbent” transmission
    provider is either “a transmission developer that does not have a retail
    distribution service territory or footprint” or “a public utility
    transmission provider that proposes a transmission project outside of
    its existing retail distribution territory or footprint. 
    Id. 51 opportunities
    for non-incumbents.     Several state utility
    commissions and municipal utilities echoed that view. See
    Order No. 1000 ¶¶ 231–37, 76 Fed. Reg. at 49,881–82.
    A number of incumbents responded that there was no need
    for the removal mandate because current processes were
    working well and attracting new developers. 
    Id. ¶ 239,
    76 Fed.
    Reg. at 49,882–83. Banning rights of first refusal, argued the
    incumbents, would require empirical evidence that they were
    adversely affecting rates. Such evidence did not exist, they
    claimed, because incumbents were better suited to develop
    transmission infrastructure, due to their expertise and
    relationships with state regulators. Any lower costs the
    Commission anticipated from removing rights of first refusal
    from tariffs and agreements would be offset by inefficiencies in
    the transmission planning process—such as a loss of economies
    of scale and scope—that would necessarily accompany the entry
    of new players less experienced in the development of
    transmission than the incumbents. Moreover, the incumbents
    contended, removing rights of first refusal posed significant
    risks to transmission system reliability and integrity, since non-
    incumbents might lack the financial backing or technical
    expertise necessary to complete projects on time. 
    Id. ¶¶ 240–50,
    76 Fed. Reg. at 49,883–85.
    The Commission proceeded with the proposed ban, 
    id. ¶¶ 253–56,
    76 Fed. Reg. at 49,885–86, but limited its reach to
    those facilities whose costs would be allocated according to the
    principles established in the regional transmission plan. This
    limitation was born of the Commission’s concern that a
    complete ban could potentially threaten grid reliability if non-
    incumbents failed to complete needed projects in a timely
    fashion. The upshot was that rights of first refusal could be
    retained for facilities located wholly within the service territory
    of an incumbent whose development costs would not be spread
    52
    to other parties (which the challenged orders refer to as “local
    transmission facilit[ies]”). 
    Id. ¶¶ 63,
    258, 76 Fed. Reg. at
    49,854, 49,886.
    The Commission further addressed reliability concerns with
    several additional requirements. For example, the Commission
    required each region to craft “criteria for determining an entity’s
    eligibility to propose a transmission project for selection in the
    regional transmission plan,” contemplating that these criteria
    would serve as benchmarks for prospective developers, who
    would be required to “demonstrate . . . the necessary financial
    resources and technical expertise to develop, construct, own,
    operate and maintain transmission facilities.” 
    Id. ¶¶ 323–24,
    76
    Fed. Reg. at 49,897. The Commission also required each region
    to implement procedures for periodically reevaluating its
    transmission plan to determine if development delays required
    identification of alternative solutions, 
    id. ¶¶ 263,
    329, 76 Fed.
    Reg. at 49,887, 49,898, thereby increasing the likelihood that
    potential threats to reliability would be identified and mitigated
    before they materialized.
    On rehearing, the Commission responded to objections by
    some incumbents who argued that the Commission could not
    lawfully strip them of their rights of first refusal without finding
    that those rights harmed the public interest. Specifically, they
    asserted that their rights were protected by the Mobile-Sierra
    doctrine. See NRG Power Mktg., LLC v. Me. Pub. Utils.
    Comm’n, 
    558 U.S. 165
    , 167 (2010). The Commission promised
    to consider the petitioners’ Mobile-Sierra arguments when it
    reviewed the new OATTs that they were required to file to
    comply with the orders. Order No. 1000-A ¶¶ 388–89, 77 Fed.
    Reg. at 32,245.
    B.
    53
    Petitioners rest their first challenge to the right of first
    refusal mandate on FPA Section 206. The Commission
    concluded that including rights of first refusal in tariffs and
    agreements was a “practice . . . affecting . . . rate[s]” within the
    meaning of the statute. Petitioners, who bear the burden of
    demonstrating agency error, see Telecomms. Research & Action
    Ctr. v. FCC, 
    801 F.2d 501
    , 510 (D.C. Cir. 1986), challenge that
    determination, but we uphold it under the Chevron framework,
    see, e.g., Bhd. of R.R. Signalmen v. Surface Transp. Bd., 
    638 F.3d 807
    , 811 (D.C. Cir. 2011).
    We begin by asking whether “Congress has directly
    spoken” to the issue of whether the inclusion of rights of first
    refusal in tariffs and agreements constitutes a practice that
    affects rates. See Bhd. of R.R. 
    Signalmen, 638 F.3d at 811
    (internal quotation marks omitted). If it has, we give effect to
    Congress’s unambiguously expressed intent. 
    Id. On its
    face,
    Section 206 seems ambiguous. Not only does it say nothing
    about rights of first refusal, but it does not even tell us what
    constitutes a practice affecting rates. Even so, petitioners raise
    two arguments that the statute unambiguously forecloses the
    Commission’s mandate.
    Petitioners first argue that the relationship between rights of
    first refusal and rates is too attenuated to trigger the
    Commission’s authority under Section 206, which is limited to
    practices “affecting” a rate. Petitioners rely primarily on
    CAISO, 
    372 F.3d 395
    . In that case, the court explained that the
    Commission’s Section 206 authority “is limited to those
    methods or ways of doing things on the part of the utility that
    directly affect the rate or are closely related to the rate, not all
    those remote things beyond the rate structure that might in some
    sense indirectly or ultimately do so.” 
    Id. at 403.
    The structure
    of a corporate board, we held, was too far removed from the
    rates that would ultimately be charged by a utility to qualify as
    54
    a “practice . . . affecting” a “rate” within the meaning of Section
    206. See 
    id. Petitioners contend
    that the relationship between rights of
    first refusal and rates is just as attenuated. We disagree. Unlike
    the corporate governance matters at issue in CAISO, a generally
    accepted principle of economics directly connects rights of first
    refusal to rates. Transmission service providers recoup the costs
    of their transmission facilities through their rates. See, e.g., Pub.
    Serv. Comm’n of Wis. v. FERC, 
    545 F.3d 1058
    , 1060–61 (D.C.
    Cir. 2008). The lower those costs, the lower their rates. See
    NEPCO Mun. Rate Comm. v. FERC, 
    668 F.2d 1327
    , 1335 (D.C.
    Cir. 1981) (“[A] regulated utility is allowed to recover from
    ratepayers all of its expenses, including income taxes, plus a
    reasonable return on capital invested in the enterprise and
    allocated to public use.”). And basic economic principles make
    clear that rights of first refusal are likely to have a direct effect
    on the costs of transmission facilities because they erect a
    barrier to entry: namely, non-incumbents are unlikely to
    participate in the transmission development market because they
    will rarely be able to enjoy the fruits of their efforts. See IIB
    PHILLIP E. AREEDA ET AL., ANTITRUST LAW 71 (3d ed. 2007)
    (“[A] barrier to entry is best defined as any factor that permits
    firms already in the market to earn returns above the competitive
    level while deterring outsiders from entering. In the perfectly
    competitive model, prices above the competitive level attract
    entry until the newcomers restore total market output to the
    competitive level, thus bringing about competitive
    performance.” (footnote omitted)). See generally 2 THE NEW
    PALGRAVE: A DICTIONARY OF ECONOMICS 156 (John Eatwell
    et al. eds., 1987) (“Entry—and its opposite, exit—have long
    been seen to be the driving forces in the neoclassical theory of
    competitive markets.”).
    55
    The relationship between rights of first refusal and rates is
    far more direct than the relationship between corporate
    governance and rates. See Order No. 1000 ¶ 289, 76 Fed. Reg.
    at 49,891; Order No. 1000-A ¶¶ 76–90, 77 Fed. Reg. at
    32,198–200. Nothing suggests that replacing the members of a
    board will necessarily affect rates. The new board members
    may manage the company well, manage it poorly, or merely stay
    the course. We simply do not know. The challenged orders
    here provide what was lacking in CAISO: an economic principle
    that directly ties the practice the Commission sought to regulate
    to rates. Compare 
    CAISO, 372 F.3d at 403
    .7
    Petitioners’ next argument is based on a comparison of the
    FPA and the Natural Gas Act (“NGA”). The NGA contains a
    provision analogous to Section 206 of the FPA that gives the
    Commission authority to regulate “practice[s] . . . affecting . . .
    rate[s]” for natural gas. See 15 U.S.C. § 717d. But the NGA
    also contains a separate provision expressly authorizing the
    Commission to regulate certain matters relating to the
    construction of natural gas pipelines. See 
    id. § 717f
    (allowing
    the Commission to order “a natural-gas company to extend or
    improve its transmission facilities” or to “establish physical
    connection of its transportation facilities with the facilities of”
    other natural gas distributors). Petitioners argue that the
    existence of this separate “construction” provision proves that
    7
    For similar reasons, United States v. Pennsylvania Railroad
    Co., 
    242 U.S. 208
    (1916), which petitioners cite, does not aid their
    argument. Although that opinion’s reasoning is difficult to follow,
    petitioners claim that that the decision established that Section 206 is
    “manifestly concerned about practices that directly relate[] to the . . .
    service provided customers.” Pet’rs’ Rights of First Refusal Br. 13.
    But, as already explained, because rights of first refusal are directly
    tied to rates charged for electricity transmission, such rights do
    directly relate to the service that is provided (i.e., the provision of
    electricity transmission service).
    56
    the Commission’s “practices affecting rates” power under the
    NGA does not authorize regulation of gas pipeline construction
    matters: if it did, there would be no need for the separate
    provision. See Corley v. United States, 
    556 U.S. 303
    , 314
    (2009) (“[A] statute should be construed so that effect is given
    to all its provisions, so that no part will be inoperative or
    superfluous, void or insignificant.” (internal quotation marks
    omitted)). Pointing to statements in our case law observing the
    similarity between the NGA and FPA and suggesting that
    interpretations of one should strongly inform interpretations of
    the other, see, e.g., Ky. Utils. Co. v. FERC, 
    760 F.2d 1321
    , 1325
    n.6 (D.C. Cir. 1985), petitioners contend that the same “practices
    affecting rates” language in Section 206 of the FPA must
    likewise not include a grant of authority to the Commission to
    regulate the building of transmission infrastructure on the grid.
    Petitioners’ argument is unconvincing and certainly does
    not demonstrate that Section 206 unambiguously precludes the
    Commission’s assertion of authority. In the first place, although
    we have observed the similarity between the FPA and NGA, and
    posited that the two statutes “should be interpreted consistently,”
    
    TAPS, 225 F.3d at 686
    , where the texts of the acts differ in some
    material respect, interpretations will diverge as well. Perhaps
    petitioners’ real point is that the NGA demonstrates that any
    time that Congress wants to give the Commission authority over
    construction matters, it does so clearly and directly. But the
    superfluity canon does not compel such an expansive reading of
    the NGA “construction” provision that petitioners invoke.
    Rather than give the Commission blanket authority over all
    construction-related matters, the provision instead authorizes it
    to order “a natural-gas company to extend or improve its
    transmission facilities” or “establish physical connection of its
    transportation facilities with the facilities of” other natural gas
    companies. See 15 U.S.C. § 717f(a). And the challenged orders
    do not require transmission providers to do either of these
    57
    activities. Thus, even assuming an absolute obligation to
    interpret the NGA and FPA in lockstep, there would be no
    superfluity. The NGA “construction” provision gives the
    Commission authority over different matters than those it
    addressed in the challenged orders.
    Because Section 206 does not unambiguously resolve the
    question of whether rights of first refusal are practices affecting
    rates, we move to Chevron step two, which requires us to uphold
    an agency’s reasonable interpretation of a statute it administers.
    See Brand X Internet 
    Servs., 545 U.S. at 980
    . As is clear from
    our discussion above, we think that the Commission’s reading
    of Section 206 is reasonable. Petitioners give us no persuasive
    reason to think otherwise. The only Chevron step two argument
    that they advance maintains that the Commission’s construction
    of Section 206 interferes with the States’ traditional authority to
    deny or approve transmission facility siting and construction.8
    But, as discussed already, 
    see supra
    Part II.C, the challenged
    orders take great pains to avoid intrusion on the traditional role
    of the States, making clear that although federal rights of first
    refusal were being removed, “nothing in th[e] Final Rule is
    intended to limit, preempt, or otherwise affect state or local laws
    or regulations with respect to construction of transmission
    facilities, including but not limited to authority over siting or
    permitting of transmission facilities.” Order No. 1000 ¶ 227, 76
    Fed. Reg. at 49,880. Thus, States retain control over the siting
    and approval of transmission facilities.            Even if the
    8
    Assuming that petitioners’ CAISO and superfluity arguments
    were Chevron step two arguments would not aid petitioners. The
    direct economic relationship between rights of first refusal and rates
    forecloses any suggestion that characterizing these rights as practices
    affecting rates was somehow impermissible. And, as explained,
    petitioners’ superfluity argument is unpersuasive.
    58
    Commission’s mandate opens up opportunities for non-
    incumbents, such developers must still comply with state law.
    In sum, Section 206 is ambiguous, and the Commission
    reasonably concluded that inclusion of rights of first refusal in
    tariffs and agreements is a “practice . . . affecting [a] rate.” The
    Commission therefore was authorized to regulate rights of first
    refusal to the extent it found their inclusion was unjust or
    unreasonable, which brings us to petitioners’ next challenge.
    C.
    Petitioners contend that the Commission did not support
    with substantial evidence, see 16 U.S.C. § 825l(b), its finding
    that the practice of including rights of first refusal in
    Commission tariffs and agreements was unjust or unreasonable.
    Although the Commission was not required to do more than
    “specify the evidence on which it relied and . . . explain how that
    evidence support[ed] the conclusion it reached,” see Wisconsin
    
    Gas, 770 F.2d at 1156
    (internal quotation marks omitted),
    petitioners claim that the right of first refusal removal mandate
    does not clear even that low hurdle. They contend that the
    mandate rested on a mere prediction, which can never support
    a finding that a “practice” is “unjust” or “unreasonable.” But
    this argument is one we have already addressed and rejected.
    
    See supra
    Part III. To repeat: at least in circumstances where
    it would be difficult or even impossible to marshal empirical
    evidence, the Commission is free to act based upon reasonable
    predictions rooted in basic economic principles. See Order No.
    1000-A ¶ 80, 77 Fed. Reg. at 32,199 (responding to the
    argument that “the Commission has not identified an instance
    where federal rights of first refusal have led to adverse effects
    on rates” by noting that “[w]e do not think it is surprising that
    there is limited evidence of exclusion of nonincumbent
    transmission developers” given that rights of first refusal give
    rise to a “situation that discourages [nonincumbents] from
    59
    proposing projects in the first place”). In this case, the
    Commission rested its right of first refusal ban on competition
    theory, determining that rights of first refusal posed a barrier to
    entry that made the transmission market inefficient, that
    transmission facilities would therefore be developed at higher-
    than-necessary cost, and that those amplified costs would be
    passed on to transmission customers.
    Petitioners argue, however, that reliance on competition
    theory is misplaced. They contend that because transmission is
    a natural monopoly, the right of first refusal ban is really nothing
    more than a regulation that makes non-incumbents eligible to
    own transmission lines, and argue that there is no reason to think
    that who owns a line will affect rates. But much more is at work
    in the orders than this argument assumes. While they
    undoubtedly will have some effect on line ownership, the focus
    of the orders is on improving the process through which needed
    infrastructure is identified and planned. As already explained,
    there is ample reason to think that injecting competition into the
    planning process will help to ensure that rates remain just and
    reasonable. 
    See supra
    Parts III.B and IV.B.
    In response, petitioners offer two reasons to doubt the effect
    of competition on rates. Neither is persuasive. First, they argue
    that Commission rules predating the challenged orders that
    required transmission providers to seek and accept input from
    interested stakeholders in planning for transmission
    infrastructure development already made likely that cost-
    effective solutions to transmission needs would be identified.
    Although petitioners are no doubt correct that the previous
    regime improved transmission planning, non-incumbent
    developers were not likely to participate in that regime because
    rights of first refusal left them with little to gain. See Order No.
    1000 ¶ 229, 76 Fed. Reg. at 49,881. By removing a pre-existing
    barrier to entry, the orders make it more likely that those key
    60
    parties will actually join that process, making the transmission
    development process more competitive, which, in the
    Commission’s reasoned expert judgment, will help to ensure
    that rates are just and reasonable. See 
    id. ¶¶ 256–57,
    76 Fed.
    Reg. at 49,886; see also Order No. 1000-A ¶¶ 76–90, 77 Fed.
    Reg. at 32,198–200.
    Petitioners also argue that the market for infrastructure
    development was already competitive prior to the challenged
    orders because non-incumbents have always been allowed to
    pursue so-called “merchant transmission projects,” whose
    construction costs are “recovered through negotiated rates
    instead of cost-based rates.” Order No. 1000 ¶ 119, 76 Fed.
    Reg. at 49,863; see also Blumenthal v. FERC, 
    552 F.3d 875
    (D.C. Cir. 2009) (discussing the difference between these types
    of rates). But those pursuing merchant projects are limited to
    charging what the market will bear, whereas other developers
    are guaranteed rates that both compensate for their costs and
    provide a reasonable rate of return. The risk of a merchant
    project is substantially greater than the risk of a project eligible
    for cost-based rates (the type of project the right of first refusal
    ban targets), see Order No. 1000 ¶ 163, 76 Fed. Reg. at 49,870,
    making it significantly less likely that merchant projects will be
    proposed (as a higher anticipated payout would be needed to
    justify taking on additional risk). Petitioners give no persuasive
    reason to doubt that the right of first refusal ban targeted a real
    deficiency in the transmission infrastructure development
    market and thus fail to satisfy their “burden of demonstrating”
    that the Commission erred. See Nat’l Small Shipments Traffic
    Conference, Inc. v. ICC, 
    725 F.2d 1442
    , 1455 (D.C. Cir. 1984).
    We accordingly reject petitioners’ challenges regarding the
    Commission’s Section 206 authority to require removing rights
    of first refusal.
    D.
    61
    Petitioners next contend that even if the Commission had
    the necessary authority, its ban on rights of first refusal was
    “arbitrary, capricious . . . or otherwise not in accordance with
    law” for a variety of reasons. See 5 U.S.C. § 706(2)(A). But
    petitioners have failed to shoulder their burden of demonstrating
    that the Commission misstepped. See Lomak Petroleum, Inc. v.
    FERC, 
    206 F.3d 1193
    , 1198 (D.C. Cir. 2000).
    1. Petitioners first argue that the Commission failed to
    consider the costs of the ban, claiming that they swamp any
    anticipated competitive benefit. Petitioners point to the loss of
    the advantages of vertical integration, interference with existing
    planning processes which allegedly were open and collaborative,
    and a reduction of transmission system reliability. Contrary to
    petitioners’ claim, however, the Commission squarely addressed
    each of these costs, satisfying its obligation to engage in
    reasoned decision-making. See State 
    Farm, 463 U.S. at 43
    .
    As to the asserted loss of the benefits of vertical integration,
    the Commission explained that removing rights of first refusal
    did not “diminish[] the importance” of factors such as
    incumbents’ “unique knowledge of their own transmission
    systems, familiarity with the communities they serve, economies
    of scale, experience in building and maintaining transmission
    facilities, and access to funds needed to maintain reliability.”
    Order No. 1000 ¶ 260, 76 Fed. Reg. at 49,887. Even with the
    ban, incumbents remained “free to highlight [their] strengths to
    support transmission project(s)” during the regional
    transmission planning process, such that there was no need to
    categorically exclude non-incumbent transmission developers
    from “presenting [their] own strengths in support of . . .
    proposals or bids.” 
    Id. Although the
    Commission shared the view of the petitioners
    that the “collaborative nature of current regional transmission
    62
    planning processes” was valuable and worthy of preservation, it
    did not expect the ban to disrupt those processes. 
    Id. ¶ 258,
    76
    Fed. Reg. at 49,886. Earlier planning mandates had already
    required transmission providers to implement measures for
    weighing alternative solutions and deciding which ones would
    best meet the region’s needs. See 
    id. Petitioners contend
    ,
    however, that the challenged orders are nearly certain to disrupt
    existing planning processes because they create a perverse
    incentive for incumbents to avoid participating fully in that
    planning. Petitioners predict that incumbents will now prefer to
    construct only projects for which they may retain rights of first
    refusal, projects which must be both wholly located within the
    incumbent’s service territory and not submitted for regional cost
    allocation, in order to minimize encroachment on their service
    territory. But this argument overlooks that the Commission
    determined that, even with the ban, incumbents have incentives
    to propose projects in the regional transmission planning
    process. Only such projects are eligible for mandatory cost
    allocation, which allows the incumbent to spread the costs of
    new infrastructure among all who benefit from it. See Order No.
    1000-A ¶¶ 179, 423, 77 Fed. Reg. at 32,214, 32,251.
    The petitioners also argued before the Commission that the
    non-incumbents’ lack of experience might so delay the
    development of transmission infrastructure that capacity would
    be unavailable when needed. The Commission reasonably
    rejected this argument, concluding that several aspects of the
    Final Rule adequately addressed reliability concerns. First, the
    orders anticipate that some non-incumbents might not be up to
    the task and call for each region to establish minimum standards
    designed to ensure that those selected to build new infrastructure
    have the necessary resources and expertise. Second, the orders
    require regions to put in place processes for monitoring the
    progress of projects in their region and assessing whether
    63
    unanticipated delays require alternative solutions.9 Third, the
    orders sought to minimize the risk that the non-incumbents’
    poor performance would harm incumbents by limiting the ban’s
    scope, permitting incumbents to retain rights of first refusal for
    upgrades to their existing transmission facilities and for “local”
    facilities. Fourth, the orders require “all entities” that operate
    regional transmission facilities, “incumbent and nonincumbent
    alike” to register with NERC and comply with all applicable
    reliability standards. See Order No. 1000 ¶¶ 260, 262–64, 266,
    342, 76 Fed. Reg. at 49,887–88, 49,900; Order No. 1000-A
    ¶¶ 425, 428, 442–43, 77 Fed. Reg. at 32,251–52, 32,254. The
    Commission carefully considered the risk that its right of first
    refusal ban might harm grid reliability and responded with a
    package of reforms designed to prevent that risk from
    materializing.10
    9
    Petitioners’ briefing takes primary aim at this requirement,
    suggesting that monitoring is unlikely to solve reliability concerns in
    light of the long lead times for transmission infrastructure construction
    projects and the unacceptability of short-term, stop-gap solutions (e.g.,
    rolling blackouts) where needed infrastructure is not in place. But this
    straw-man argument overlooks the other aspects of the Commission’s
    response to reliability concerns.
    10
    The orders belie petitioners’ assertion that the Commission
    failed to address comments raising concerns that potential state
    sanctions and civil liability might result if non-incumbent delays led
    to interrupted electricity service. On rehearing, the Commission
    reasonably determined that because these concerns were speculative,
    see Order No. 1000-A ¶ 482, 77 Fed. Reg. at 32,259, they “require[d]
    no response,” see Home Box Office, Inc. v. FCC, 
    567 F.2d 9
    , 35 n.58
    (D.C. Cir. 1977). The Commission did not need to promise total
    immunity from any conceivable reliability-related risks to make its
    decision rational.
    64
    2. Section 215 of the FPA directs the Commission to
    designate an Electric Reliability Organization (ERO) to
    “establish and enforce reliability standards for the bulk-power
    system, subject to Commission review.”               16 U.S.C.
    § 824o(a)(2). The Commission has designated NERC as the
    ERO. See generally 
    Alcoa, 564 F.3d at 1344
    –45 (providing
    background about NERC). NERC, not the Commission, has
    primary responsibility for creating mandatory standards
    designed to “provide for an adequate level of reliability of the
    Bulk-Power System.” See N. Am. Electric Reliability Corp., 116
    F.E.R.C. ¶ 61,062 at ¶ 25. In fact, when the Commission
    disapproves of a NERC reliability standard, it can only remand
    the standard to NERC. 16 U.S.C. § 824o(d)(4). It may not
    modify the standard directly. The Commission may, however,
    order NERC to address specific problems on remand. 
    Id. § 824o(d)(5).
    Importantly, though, FPA Section 215 does not
    authorize the Commission or NERC to “order the construction
    of additional generation or transmission capacity.” 
    Id. § 824o(i)(2).
    The petitioners argue that several components of the ban on
    rights of first refusal violate Section 215. They first target the
    requirements that transmission providers must (1) periodically
    evaluate the progress of infrastructure construction projects that
    could impact system reliability, and (2) submit a NERC
    mitigation plan designed to prevent any reliability concerns from
    materializing.      Operating from the premise that these
    requirements are new, petitioners argue that only NERC, and not
    the Commission, could impose them. But their argument fails
    because its premise is false. Existing NERC reliability standards
    already required such monitoring and mitigation. See Order No.
    1000-A ¶ 479, 77 Fed. Reg. at 32,259; see also Cal. Indep. Sys.
    Operator Corp., 143 F.E.R.C. ¶ 61,057 at ¶ 269 (Apr. 18, 2013).
    See generally NERC Reliability Standards for the Bulk Electric
    Systems of North America, Transmission Planning and Facilities
    65
    Connection Series, available at http://www.nerc.com/pa
    /Stand/Pages/AllReliabilityStandards.aspx?jurisdiction=United
    States (last visited Aug. 1, 2014). Thus, because the challenged
    orders did not modify NERC’s reliability standards, the
    Commission did not need to follow the process prescribed by
    Section 215 for changing them.11
    Petitioners also argue that the orders’ duty to develop
    mitigation plans runs afoul of Section 215’s declaration that it
    “does not authorize [NERC] or the Commission to order the
    construction of additional . . . transmission capacity.” 16 U.S.C.
    § 824o(i)(2). They contend that a non-incumbent’s failure to
    complete a transmission project might require an incumbent to
    step in and complete construction. But though this may be the
    ideal method of mitigation, other approaches are also possible.
    See, e.g., Conn. Dep’t of Pub. Util. Control v. FERC, 
    569 F.3d 477
    , 480 (D.C. Cir. 2009) (explaining that certain end users of
    power can “reduce their demand during shortages”); see also
    Electric Power Supply Ass’n v. FERC, 
    753 F.3d 216
    , 221 (D.C.
    Cir. 2014) (“Demand response will also increase system
    reliability.”).  More importantly, the challenged orders
    repeatedly make clear that incumbents are never required to
    mitigate by constructing new capacity. See Order No. 1000
    ¶ 344, 76 Fed. Reg. at 49,900; Order No. 1000-A ¶ 490, 77 Fed.
    11
    In petitioners’ right of first refusal reply brief, they assert
    that the orders’ mitigation requirement is new because it requires
    transmission providers to submit a mitigation plan before a reliability
    violation occurs. Petitioners contend that this “modifies the current
    NERC enforcement process, which does not permit a mitigation plan
    until a violation exists.” Pet’rs’ Rights of First Refusal Reply Br. 22.
    But petitioners failed to raise this argument with sufficient
    particularity in their opening brief. See Pet’rs’ Rights of First Refusal
    Br. 43–47. Accordingly, we refrain from addressing it. See, e.g.,
    Domtar Me. 
    Corp., 347 F.3d at 309
    –10.
    66
    Reg. at 32,260. Accordingly, the challenged orders do not
    violate Section 215’s bar against requiring construction.
    In comments submitted during the rulemaking process,
    incumbents expressed concern that they might be penalized by
    NERC for reliability violations stemming from the failures of
    non-incumbents beyond their control. The Commission
    responded by promising not to penalize incumbents for such
    reliability violations. See Order No. 1000-A ¶ 480, 77 Fed. Reg.
    at 32,259.       Petitioners contend that this promise was
    incompatible with Section 215 because NERC, not the
    Commission, is the entity directed to police reliability standards
    and NERC lacks authority to waive noncompliance penalties.
    What petitioners miss, however, is that even if NERC imposed
    such a penalty on an incumbent, the Commission, which is
    authorized to review all NERC penalties, would be able to honor
    the promise it made in the challenged orders by freeing that
    incumbent from the penalty. See 16 U.S.C. § 824o(e)(2).
    Petitioners thus fail to demonstrate that the challenged orders
    violate Section 215.
    3. According to the petitioners, the orders’ right of first
    refusal removal mandate violates the Mobile-Sierra doctrine,
    which presumes that freely-negotiated wholesale-energy
    contracts are just and reasonable unless found to seriously harm
    the public interest. See NRG Power 
    Mktg., 558 U.S. at 167
    .
    Some of the petitioners argue that the Commission unlawfully
    deprived them of their rights of first refusal without making the
    finding required to rebut the Mobile-Sierra presumption. But
    this argument misconstrues the challenged orders, which, as
    noted already, make clear that the Commission will hear the
    petitioners’ Mobile-Sierra arguments when it reviews the new
    OATTs that utilities must file to comply with the orders. Order
    No. 1000-A ¶¶ 388–89, 77 Fed. Reg. at 32,245; cf. also Mobil
    Oil Exploration & Producing Se. Inc. v. United Distrib. Cos.,
    67
    
    498 U.S. 211
    , 230 (1991) (explaining that an agency has “broad
    discretion in determining how best to handle related, yet
    discrete, issues in terms of procedures” and that an agency is
    free to treat a particular issue in a “different proceeding” where
    that “proceeding would generate more appropriate information
    and where the agency was addressing the question”); 
    TAPS, 225 F.3d at 709
    .
    To the extent petitioners are asking us to weigh in now on
    whether or how Mobile-Sierra will ultimately apply to particular
    contracts, we decline their invitation.          Given that the
    Commission deferred consideration of the issue, the “decision
    has [not yet] been formalized and its effects [have not been] felt
    in a concrete way by the challenging parties.” Associated Gas
    
    Distributors, 824 F.2d at 1007
    (internal quotation marks
    omitted). Thus, our involvement would be premature. See
    Nevada v. Dep’t of Energy, 
    457 F.3d 78
    , 85–86 (D.C. Cir. 2006)
    (clarifying that an issue is not “fit for judicial review” where
    “further administrative action is needed to clarify the agency’s
    position” (internal quotation marks omitted)).
    We also see no need to enter an order precluding the
    Commission from holding, in later proceedings, that petitioners
    may not raise their argument because it is collaterally barred.
    As explained, the challenged orders make clear that the
    Commission will consider the issue during compliance. See
    Order No. 1000 ¶ 292, 76 Fed. Reg. at 49,892; Order No. 1000-
    A ¶¶ 388–89, 77 Fed. Reg. at 32,245. We have no reason to
    doubt that the Commission will honor its promise. See Comcast
    Corp. v. FCC, 
    526 F.3d 763
    , 769 n.2 (D.C. Cir. 2008)
    (explaining that this court presumes that an “agency acts in good
    faith”). If it fails to do so, its decision will be reviewable.
    68
    Finding no merit in any of petitioners’ right of first refusal
    challenges, we deny those portions of their petitions that attack
    the ban.
    V.
    Cost Allocation. As a key element of the regional planning
    process, the Final Rule requires transmission providers to devise
    methods for allocating the costs of certain new transmission
    facilities to those entities that benefit from them. In keeping
    with the overall approach of the transmission planning reforms,
    the Final Rule uses a light touch: it does not dictate how costs
    are to be allocated. Rather, the Rule provides for general cost
    allocation principles and leaves the details to transmission
    providers to determine in the planning processes.
    Two groups of petitioners challenge the cost allocation
    provisions on nearly opposite grounds. One, the Joint
    Petitioners, contends that the Commission lacks sufficient
    statutory authority to adopt the cost allocation requirements.
    The other, the International Transmission Company Petitioners
    (“ITC Petitioners”), asserts that the Commission acted
    arbitrarily and capriciously in adopting them, essentially because
    the agency did not go far enough. We disagree on both counts.
    A.
    Before the current reforms, the Commission did not
    mandate that the costs of new transmission facilities be allocated
    ex ante to those who would benefit from those facilities. The
    Commission has since concluded that the lack of any method or
    process to ensure that new facilities were paid for by those that
    benefitted from them created perverse incentives—indeed, a sort
    of tragedy of the transmission commons.
    69
    As the Commission explained, the challenges associated
    with allocating the cost of new or improved transmission
    facilities have become more pressing as the need for such
    infrastructure has grown. Order No. 1000 ¶ 485, 76 Fed. Reg.
    at 49,919. That is because “constructing new transmission
    facilities requires a significant amount of capital and, therefore,
    a threshold consideration for any company considering investing
    in transmission is whether it will have a reasonable opportunity
    to recover its costs.” 
    Id. In the
    Commission’s view, the lack of
    methods that ascertain the beneficiaries of new and improved
    transmission facilities and allocate costs to entities that benefit
    “creates significant risk for transmission developers that they
    will have no identified group of customers from which to
    recover the cost of their investment.” 
    Id. The Commission
    reasoned:
    [T]he risk of the free rider problems associated with
    new transmission investment is particularly high for
    projects that affect multiple utilities’ transmission
    systems and therefore may have multiple beneficiaries.
    With respect to such projects, any individual
    beneficiary has an incentive to defer investment in the
    hopes that other beneficiaries will value the project
    enough to fund its development. . . . [O]n one hand, a
    cost allocation method that relies exclusively on a
    participant funding approach, without respect to other
    beneficiaries of a transmission facility, increases this
    incentive and, in turn, the likelihood that needed
    transmission facilities will not be constructed in a
    timely manner. On the other hand, if costs would be
    allocated to entities that will receive no benefit from a
    transmission facility, then those entities are more likely
    to oppose selection of the facility in a regional
    transmission plan for purposes of cost allocation or to
    70
    otherwise impose obstacles that delay or prevent the
    facility’s construction.
    
    Id. ¶ 486,
    76 Fed. Reg. at 49,919 (footnote omitted).
    The Commission anticipated that such misalignment of
    incentives would become more acute due to the “growing need
    for new transmission facilities [including those] that cross . . .
    regions” created by “the expansion of regional power markets.”
    
    Id. ¶ 484,
    76 Fed. Reg. at 49,919. In addition, the Commission
    noted that the “increasing adoption of state resource policies,
    such as renewable portfolio standards, has contributed to the
    rapid growth of renewable energy resources that are frequently
    remote from load centers.” 
    Id. In short,
    the Commission
    recognized that, unless costs were allocated to those who
    benefit, needed expansion and improvement of the power grid
    would not likely occur. The Commission accordingly concluded
    that “existing cost allocation methods may not appropriately
    account for benefits associated with new transmission facilities
    and, thus, may result in rates that are not just and reasonable or
    are unduly discriminatory or preferential.” 
    Id. ¶ 487,
    76 Fed.
    Reg. at 49,919.
    For these reasons, in the Final Rule, the Commission
    required each public utility transmission provider to participate
    in a regional transmission planning process that includes, with
    regard to cost allocation, both:
    (1) “[a] regional cost allocation method for the cost of
    new transmission facilities selected in a regional
    transmission plan for purposes of cost allocation”; and
    (2) “an interregional cost allocation method for the cost
    of certain new transmission facilities that are located in
    two or more neighboring transmission planning regions
    71
    and are jointly evaluated by the regions in the
    interregional transmission coordination procedures
    required by this Final Rule.”
    Order No. 1000 Summary, 76 Fed. Reg. at 49,842.
    The reforms do not require any particular provider to pay
    for new facilities or dictate precisely how costs must be
    allocated. Instead, the Commission requires public utilities to
    have in place a method or methods for allocating the costs of
    new transmission facilities “in a manner that is at least roughly
    commensurate with the benefits received by those who will pay
    those costs,” and for ensuring that costs are not “involuntarily
    allocated to entities that do not receive benefits.” 
    Id. ¶ 10,
    76
    Fed. Reg. at 49,846.
    To implement these reforms, the Commission requires each
    public utility transmission provider to include in its OATT both
    “a method, or set of methods, for allocating the costs of new
    transmission facilities selected in the regional transmission plan”
    and “a method or set of methods for allocating the costs of new
    interregional transmission facilities.” 
    Id. ¶ 482,
    76 Fed. Reg. at
    49,918. Each utility in a region “must include the same cost
    allocation method or methods adopted by the region.” 
    Id. ¶ 482,
    76 Fed. Reg. at 49,919; Order No. 1000-A ¶ 523, 77 Fed. Reg.
    at 32,266. The Commission also required both regional and
    interregional cost allocation method(s) to adhere to six specified
    principles, including, for example, that costs must be allocated
    roughly commensurately with benefits, that those entities that
    receive no benefit must not be involuntarily allocated costs, and
    that the allocation method(s) for the costs of a regional facility
    must assign costs within the transmission planning region unless
    entities outside the region voluntarily assume them. See Order
    No. 1000 ¶¶ 586–87, 76 Fed. Reg. at 49,932–33.
    72
    Thus, although the Final Rule requires each public utility in
    a region to include the same cost allocation method(s) in its
    OATT, it does not dictate either how the costs should be
    allocated in any more detail than those general principles, nor
    does the Rule specify how costs should be recovered (i.e., how
    the new facilities should be paid for). The Commission,
    moreover, requires cost allocation only for new transmission
    facilities that are chosen for cost allocation during the regional
    planning process—meaning that cost allocation will be triggered
    only in cases in which the transmission providers in a region, in
    consultation with stakeholders, evaluate a given facility and
    determine that its benefits merit cost allocation under the
    regional cost allocation method(s). 
    Id. ¶ 539,
    76 Fed. Reg. at
    49,926–27; Order No. 1000-A ¶ 579, 77 Fed. Reg. at 32,274.
    B.
    Petitioners dispute the Commission’s authority to adopt the
    cost allocation reforms under Section 206 of the FPA. The key
    inquiry here, as in Parts II.A and 
    IV.B supra
    is whether cost
    allocation constitutes a “practice” “affecting . . . rate[s]” under
    Section 206 of the FPA such that the Commission may fix it by
    order. 16 U.S.C. § 824e(a).
    Petitioners do not dispute that the allocation of costs of new
    transmission facilities is a “practice” that at least in principle can
    “affect” a “rate.” This court has previously held that the
    Commission has “clear” authority to reallocate capacity and
    production costs. La. Pub. Serv. Comm’n v. FERC, 
    522 F.3d 378
    , 389–90 (D.C. Cir. 2008); Miss. Indus. v. FERC, 
    808 F.2d 1525
    , 1540 (D.C. Cir. 1987) (“[D]istribution of [a facility’s]
    costs and capacity in [a cost-sharing agreement] inevitably
    affects [the allocated companies’] generation costs and, by
    extension, their wholesale rates.”). Indeed, quite recently we
    noted that “in principle, a ‘beneficiary pays’ approach is a just
    and reasonable basis for allocating the costs of regional
    73
    transmission projects, even if it leads to reallocating sunk costs.”
    FirstEnergy Serv. Co. v. FERC, -- F.3d --, No. 12-1461, 
    2014 WL 3538062
    , at *7 (D.C. Cir. July 18, 2014).
    The central thrust of Joint Petitioners’ statutory argument is
    that Section 206 does not authorize the Commission to require
    utilities to pay for the costs of transmission facilities developed
    by entities with whom they have no prior contractual or
    customer relationship and from whom they do not take
    transmission service. Joint Br. of Pet’rs/Intervenors Concerning
    Cost Allocation 2 (“Joint Pet’rs’ Br.”). In the Joint Petitioners’
    view, Section 206 unambiguously forecloses the Commission
    from mandating the allocation of costs beyond pre-existing
    commercial relationships, and the cost allocation reforms thus
    fail at Chevron step one.
    No such limitation exists in the statutory text. Section 206
    empowers the Commission to fix any “practice” affecting rates,
    and the Commission reasonably understood beneficiary-based
    cost allocation—or its absence—to be a practice affecting rates.
    Section 206 nowhere limits cost allocation to entities with pre-
    existing commercial relationships. To the contrary, it empowers
    the Commission to fix “any rate” “demanded, observed,
    charged, or collected by any public utility for any
    transmission . . . subject to the jurisdiction of the Commission,”
    and “any . . . practice” “affecting such rate.” 16 U.S.C.
    § 824e(a) (emphasis added). The use of “any” to describe
    “rate,” “public utility,” and “transmission” bestows authority on
    the Commission that is not cabined to pre-existing commercial
    relationships of any given utility. See 
    Gonzales, 520 U.S. at 5
    .
    The beneficiary-based cost allocation reforms are not clearly a
    “remote thing[] beyond the rate structure,” as was the personnel
    and structure of the corporate board in 
    CAISO, 372 F.3d at 403
    .
    Instead, “the statute is silent or ambiguous with respect to the
    74
    specific issue.”

    also supra
    Part

    We therefore defer, at Chevron step two, to the
    Commission’s interpretation of the Act if it is permissible.

    . We believe that it is.
    First, as noted above, nothing in the statutory language or
    context limits the Commission’s authority to fixing only
    practices affecting pre-existing commercial relationships.
    Second, the Commission’s adoption of a beneficiary-based
    cost allocation method is a logical extension of the cost
    causation principle. Under that basic tenet, which we have
    repeatedly embraced, “costs are to be allocated to those who
    cause the costs to be incurred and reap the resulting benefits.”
    Nat’l Ass’n of Regulatory Util. Comm’rs v. FERC, 
    475 F.3d 1277
    , 1285 (D.C. Cir. 2007) (“NARUC”). And we have
    “endorsed the approach of ‘assign[ing] the costs of system-wide
    benefits to all customers on an integrated transmission grid.’”
    
    Id. (alteration in
    original) (quoting W. Mass. Elec. Co. v. FERC,
    
    165 F.3d 922
    , 927 (D.C. Cir. 1999)).
    The physics of electrical transmission supports the
    Commission’s conclusion that even transmission providers
    distant from new transmission facilities—including those that do
    not have pre-existing commercial relationships with a
    transmission developer—may benefit from those new facilities.
    Because “there is no way to determine what path electricity
    actually takes between two points [on a power grid] or indeed
    whether the electricity at the point of delivery was ever at the
    point of origin,” “all of the individual facilities used to transmit
    electricity are treated as if they were part of a single machine.”
    75
    N. States Power Co. v. FERC, 
    30 F.3d 177
    , 179 (D.C. Cir.
    1994). And because “a transmission system performs as a
    whole[,] the availability of multiple paths for electricity to flow
    from one point to another contributes to the reliability of the
    system as a whole.” 
    Id. The Commission
    accordingly
    determined that “in an interconnected electric transmission
    system, the enlargement of one path between two points can
    provide greater system stability, lower line losses, reduce
    reactive power needs, and improve the throughput capacity on
    other facilities.” Order No. 1000-A ¶ 562, 77 Fed. Reg. at
    32,271. There is a strong scientific basis for the Commission’s
    conclusion that “[e]ntities that contract for service on the
    transmission grid cannot ‘choose’ to affect only the transmission
    facilities for which they have entered into a contract” and
    “cannot claim that they are not using or benefiting from such
    transmission facilities simply because they did not enter a
    contract to use them.” 
    Id. ¶ 561,
    77 Fed. Reg. at 32,271.
    As the Commission recognized, the free rider problem it
    identified stems from the fact that an entity that uses part of the
    transmission grid may obtain benefits from improvements to and
    expansion of transmission facilities on another part of that grid,
    regardless of whether that entity has a contract for service on the
    improved part of the grid. 
    Id. ¶ 562,
    77 Fed. Reg. at 32,271.
    The Commission therefore reasonably identified the lack of
    beneficiary-based cost allocation as a practice likely to result in
    rates that are not just and reasonable or are unduly
    discriminatory or preferential. Order No. 1000 ¶ 487, 76 Fed.
    Reg. at 49,919. And, as explained in Part 
    II.A supra
    , whether a
    threat of unjust or unreasonable rates derives from a practice or
    the absence thereof, Section 206 empowers the Commission to
    address it.
    The plain text of the statute and the Commission’s
    reasoning show the Commission’s construction to be wholly
    76
    reasonable. Joint Petitioners point to a number of cases for the
    contrary conclusion, none of which requires a different result.
    First, Joint Petitioners contend that the Mobile-Sierra line
    of cases prevents the Commission from requiring cost allocation
    other than as established by voluntary contractual or commercial
    relationships. The Mobile-Sierra cases neither govern our
    inquiry nor require that conclusion. Mobile and Sierra address
    the Commission’s authority “to modify rates set bilaterally by
    contract rather than unilaterally by tariff.” Morgan 
    Stanley, 554 U.S. at 532
    (addressing the scope of the Mobile-Sierra doctrine);
    see also Mobile, 
    350 U.S. 332
    ; Sierra, 
    350 U.S. 348
    . Neither
    Mobile-Sierra nor their progeny addressed the issue here: the
    Commission’s power under Section 206 to require public
    utilities to include in their OATTs rate-affecting provisions,
    such as cost allocation method(s) that may be adopted during
    regional transmission planning. The precedents relevant to that
    issue establish that the Commission may act by generic rule, as
    it did here, without first finding that the rates charged by
    individual utilities are unjust or unlawful when it “conclu[des]
    that any tariff violating the rule would have such adverse effects
    on the interstate gas [or energy] market as to render it ‘unjust
    and unreasonable.’” Associated Gas 
    Distributors, 824 F.2d at 1008
    ; see also Interstate Natural 
    Gas, 285 F.3d at 37
    –38; cf.
    Entergy Servs., Inc. v. FERC, 
    319 F.3d 536
    , 545 (D.C. Cir.
    2003).
    The contract cases do not bear the weight Joint Petitioners
    place on them. They reflect a premise of the FPA’s regulatory
    system in which contractual agreements voluntarily devised by
    regulated companies coexist with tariffs. See Morgan 
    Stanley, 554 U.S. at 531
    –34. But Mobile and Sierra do not wall off
    certain “private commercial matters,” Joint Pet’rs’ Br. 10, as
    beyond the Commission’s authority where those matters are
    unjust, unreasonable, or unduly discriminatory “practice[s]”
    77
    “affecting” “rate[s]” pursuant to Section 206. See 16 U.S.C.
    § 824e(a). The statutory question here is instead one we review
    under Chevron, and, as explained above, we conclude that the
    Commission’s interpretation is reasonable.
    Second, to the extent petitioners rely on Fort Pierce
    Utilities Authority v. FERC, 
    730 F.2d 778
    (D.C. Cir. 1984), for
    the proposition that the cost allocation reforms are
    impermissible as tantamount to joint rates, that assertion is
    unpersuasive. In Fort Pierce, several Florida municipal electric
    utilities (“Florida Cities”) sought review of a Commission order
    establishing the transmission rates of the largest electric utility
    in Florida, Florida Power & Light. 
    Id. at 779–80.
    The Florida
    Cities claimed that those rates were excessive and
    discriminatory, in violation of the FPA, because the Commission
    had failed to order Florida Power & Light to file joint rates with
    a second large utility, Florida Power Corporation. 
    Id. This court
    upheld the Commission’s adoption of separate, not joint,
    rates. 
    Id. Due to
    the methodology used to calculate the rates of
    each transmission provider, the Commission concluded and this
    court agreed that to permit the Cities to pay only a joint (or
    averaged) rate instead of the sum of two individual rates would
    have the effect of discriminating against non-joint-rate
    customers by forcing them to subsidize the Cities’ rates for no
    justifiable reason. 
    Id. at 783–84.
    The cost allocation reforms here are not tantamount to
    mandating joint rates under Fort Pierce. The Commission in
    Fort Pierce rejected the Cities’ proposal of a joint rate because,
    due to the rate formula used, such a rate would discriminatorily
    shift costs away from the beneficiaries of transmission service.
    
    Id. at 783.
    By contrast, the cost allocation reforms here are
    aimed at ensuring that the costs of new transmission services are
    in fact allocated to those that benefit from them. Order No.
    1000 ¶ 10, 76 Fed. Reg. at 49,846. In any event, the reforms do
    78
    not require any rate, joint or otherwise, to be paid; indeed, they
    do not require any utility to pay any cost or define the
    mechanism for doing so, leaving to the transmission providers
    to devise for themselves cost allocation methodologies and
    recovery mechanisms.
    We therefore reject the Joint Petitioners’ challenges to the
    Commission’s authority to adopt the cost allocation reforms
    under Section 206.
    C.
    In contrast to the Joint Petitioners, the ITC Petitioners
    contend that the cost allocation requirements adopted in the
    Final Rule were arbitrary and capricious because the
    Commission did not mandate further cost allocation reforms.
    Specifically, the ITC Petitioners argue that the Commission
    acted arbitrarily and capriciously by (1) failing to require the
    allocation of the costs of extra-high voltage (“EHV”) electrical
    transmission lines between regions, and (2) requiring
    interregional transmission lines to be approved by each
    transmission planning region in which the line is located. Br. of
    Pet’rs Int’l Transmission Co. 2 (“ITC Br.”). The ITC Petitioners
    complain that the Final Rule fails to require cost allocation to
    extra-regional beneficiaries.
    Principle 4 of the six regional cost allocation principles
    directs that the allocation method for “the cost of a regional
    facility must allocate costs solely within that transmission
    planning region unless another entity outside the region or
    another transmission planning region voluntarily agrees to
    assume a portion of those costs.” Order No. 1000 ¶ 586, 76 Fed.
    Reg. at 49,932; see also 
    id. ¶ 657,
    76 Fed. Reg. at 49,941. The
    Final Rule specifies that “an interregional transmission facility
    must be selected in both of the relevant regional transmission
    plans for purposes of cost allocation in order to be eligible for
    79
    interregional cost allocation pursuant to an interregional cost
    allocation method required under this Final Rule.” 
    Id. ¶ 400,
    76
    Fed. Reg. at 49,908. And “public utility transmission providers
    in a transmission planning region will not be required to accept
    allocation of the costs of an interregional transmission project
    unless the region has selected such transmission facility in the
    regional transmission plan for purposes of cost allocation.” 
    Id. ¶ 443,
    76 Fed. Reg. at 49,914.
    The Commission thus limited required cost allocation to
    within regions, noting that doing so, “may lead to some
    beneficiaries of transmission facilities escaping cost
    responsibility because they are not located in the same
    transmission planning region as the transmission facility.” 
    Id. ¶ 660,
    76 Fed. Reg. at 49,942. It chose this approach because
    “allowing one region to allocate costs unilaterally to entities in
    another region would impose too heavy a burden on
    stakeholders to actively monitor transmission planning processes
    in numerous other regions, from which they could be identified
    as beneficiaries and be subject to cost allocation.” Id.; see also
    Order No. 1000-A ¶¶ 507–12, 707–12, 77 Fed. Reg. at
    32,263–64, 32,291–92. The Commission declined to require
    cost allocation more broadly because “the resulting regional
    transmission planning processes would amount to
    interconnectionwide transmission planning with corresponding
    cost allocation, albeit conducted in a highly inefficient manner.”
    Order No. 1000 ¶ 660, 76 Fed. Reg. at 49,942.
    The ITC Petitioners contend that Cost Allocation Principle
    4 is inconsistent with the cost causation principle and is
    therefore presumptively unjust. The cost causation principle
    requires costs “to be allocated to those who cause the costs to be
    incurred and reap the resulting benefits.” 
    NARUC, 475 F.3d at 1285
    ; see also K N Energy, Inc. v. FERC, 
    968 F.2d 1295
    , 1300
    (D.C. Cir. 1992). “Not surprisingly, we evaluate compliance
    80
    with this unremarkable principle by comparing the costs
    assessed against a party to the burdens imposed or benefits
    drawn by that party. Also not surprisingly, we have never
    required a ratemaking agency to allocate costs with exacting
    precision.” Midwest ISO Transmission 
    Owners, 373 F.3d at 1368
    –69 (citation omitted).
    The ITC Petitioners urge that Cost Allocation Principle 4 is
    arbitrary and capricious because it is inconsistent with the cost
    causation principle, insofar as the Final Rule does not fully
    allocate costs to those out-of-region entities who benefit simply
    because they are not within the same “rather arbitrar[ily]” drawn
    region in which the new facility is located. ITC Br. 17. The
    ITC Petitioners further argue that the Commission’s concern
    about the monitoring burden that extra-regional cost allocation
    would create is exaggerated and could be mitigated by, for
    example, limiting out-of-region cost allocation to EHV facilities
    or to adjacent regions, because (1) only a small number of EHV
    lines are likely to have benefits beyond the region in which they
    are located; and (2) those benefits would extend only to adjacent
    regions. 
    Id. at 6.
    In the Final Rule, the Commission recognized both that
    Cost Allocation Principle 4 may lead to some beneficiaries
    escaping cost responsibility, Order No. 1000 ¶ 660, 76 Fed. Reg.
    at 49,942, and that limiting involuntary interregional cost
    allocation to EHV lines or adjacent regions “might mitigate” the
    monitoring burden on some stakeholders, Order No. 1000-A
    ¶ 711, 77 Fed. Reg. at 32,292. But nothing requires the
    Commission to ensure full or perfect cost causation. Rather, the
    cost causation principle requires that “all approved rates reflect
    to some degree the costs actually caused by the customer who
    must pay them.” K N 
    Energy, 968 F.2d at 1300
    (emphasis
    added); see also Pub. Serv. Comm’n of 
    Wis., 545 F.3d at 1066
    –67.
    81
    We recognize that “feasibility concerns play a role in
    approving rates,” such that the Commission “is not bound to
    reject any rate mechanism that tracks the cost-causation
    principle less than perfectly.” Sithe/Independence Power
    Partners, L.P. v. FERC, 
    285 F.3d 1
    , 5 (D.C. Cir. 2002); see also
    Carnegie Natural Gas Co. v. FERC, 
    968 F.2d 1291
    , 1293–94
    (D.C. Cir. 1992) (noting that there is “no requirement in the Act
    itself that rates precisely match cost causation and
    responsibility” and that instead “the Commission may rationally
    emphasize other, competing policies and approve measures that
    do not best match cost responsibility and causation”). The
    Commission is, moreover, “free to undertake reform one step at
    a time,” and “[w]e can overturn its gradualism only if it truly
    yields unreasonable discrimination or some other kind of
    arbitrariness.” Interstate Natural 
    Gas, 285 F.3d at 35
    . As such,
    the Commission’s balancing of the competing goals of reducing
    monitoring burdens and adopting policies that ensure that cost
    allocation maximally reflects cost causation is wholly
    reasonable under the deferential review we accord in rate-related
    matters. See 
    Alcoa, 564 F.3d at 1347
    .
    The ITC Petitioners’ second contention is that the
    requirement that interregional facilities be approved by each
    region in order to qualify for cost allocation is redundant with
    the required interregional coordination and will stifle the sorts
    of interregional solutions that the Final Rule aims to foster. But
    as laid out in the Rule, the bulk of planning occurs within
    regions. The Commission adopted region-based planning for
    interregional facilities on the basis that doing so would give
    stakeholders “the opportunity to participate fully in the
    consideration of interregional transmission facilities” and that
    “stakeholder participation in the various regional transmission
    planning processes will enhance the effectiveness of
    interregional transmission coordination.” Order No. 1000 ¶ 465,
    76 Fed. Reg. at 49,916–17. This was neither arbitrary nor
    82
    capricious. The Commission reasonably concluded that
    requiring neighboring regions to share regional plans and jointly
    evaluate potential interregional facilities was complementary to,
    rather than redundant with, regional planning.
    We therefore reject the challenges to the cost allocation
    reforms.
    VI.
    Public Policy Requirement. Petitioners raise three
    challenges to the orders’ requirement that regions establish
    procedures that account for the impact federal, state, and local
    laws and regulations (i.e., public policy requirements) will have
    on transmission systems. None is persuasive. According to the
    Commission, this mandate responds to a recent proliferation of
    laws and regulations affecting the power grid. For example, the
    Commission expects that many States will require construction
    of new transmission infrastructure to integrate sources of
    renewable energy, such as wind farms, into the grid and that
    new federal environmental regulations will shape utilities’
    decisions about when to retire old coal-based generators. Plans
    that fail to account for such laws and regulations, the
    Commission reasoned, would not adequately reflect future
    needs. See Order No. 1000-A ¶¶ 205–06, 336, 77 Fed. Reg. at
    32,217–18, 32,236.
    The orders allow regions to address in a flexible manner the
    impact such public policy requirements will have on
    transmission. Rather than mandating any particular outcome,
    the challenged orders require transmission providers to establish
    procedures to address the effects of public policy on the
    electricity grid. See Order No. 1000 ¶¶ 109, 111, 206–10, 76
    Fed. Reg. at 49,861–62, 49,877–78; Order No. 1000-A ¶¶ 209,
    318–21, 77 Fed. Reg. at 32,218, 32,234. A utility must
    83
    “describe these procedures in sufficient detail in its OATT such
    that the process for stakeholders to provide input and offer
    transmission proposals regarding transmission needs they
    believe are driven by public policy requirements in the regional
    transmission planning process is transparent to all interested
    stakeholders.” NorthWestern Corp., 143 F.E.R.C. ¶ 61,056 at ¶
    84 (2013). Plans are not required to take every need into
    account, see Order No. 1000-A ¶¶ 320–21, 77 Fed. Reg. at
    32,234; instead, regions must only create procedures to
    “identify, out of the larger set of potential transmission needs
    driven by public policy requirements that may be proposed,
    those transmission needs for which transmission solutions will
    be evaluated in the . . . regional transmission planning process.”
    NorthWestern Corp., 143 F.E.R.C. ¶ 61056 at ¶ 85.
    A.
    Petitioners assert that the Commission lacks statutory
    authority to promote the public welfare. See NAACP v. FPC,
    
    425 U.S. 662
    , 669–70 (1976) (noting that the FPA did not grant
    the Commission “a broad license to promote the general public
    welfare”). It is difficult to understand petitioners’ precise
    argument, but they seem to argue that the Commission can only
    exercise authority to promote goals specified in the FPA and that
    the public policy mandate cannot be justified with respect to any
    of those goals. This argument misunderstands the nature of the
    mandate. It does not promote any particular public policy or
    even the public welfare generally. The mandate simply
    recognizes that state and federal policies might affect the
    transmission market and directs transmission providers to
    consider that impact in their planning decisions. In this regard,
    the requirement is no different from other facets of the planning
    process. The providers assess what transmission capacity is
    required to fulfill a variety of needs (such as reliability of the
    grid, geographic expansion, and now public policy
    requirements) and then plan how to develop that capacity. See
    84
    Order No. 1000 ¶¶ 11, 21, 76 Fed. Reg. at 49,846, 49,848. This
    fits comfortably within the Commission’s authority under
    Section 206. Unlike the employment discrimination by power
    companies that the Court held was beyond the Commission’s
    jurisdiction in NAACP, the public policy mandate bears directly
    on the provision of transmission service. Petitioners’ argument
    that the orders seek to unlawfully promote the general welfare
    is misplaced.
    B.
    Petitioners next argue that the orders’ public policy mandate
    violates Section 217(b)(4) of the FPA, which states that the
    Commission “shall exercise [its authority] under this chapter in
    a manner that facilitates the planning and expansion of
    transmission facilities to meet the reasonable needs of load-
    serving entities to satisfy [their] service obligations.” 16 U.S.C.
    § 824q(b)(4).12 Petitioners argue that by failing to require
    regions to specifically consider the needs of load-serving
    entities, the Commission unlawfully demoted those needs in
    violation of the plain meaning of Section 217(b)(4).
    This contention, however, misses the mark. Section
    217(b)(4) creates a requirement for the Commission, not for
    utilities. It requires that the Commission act in such a way to
    facilitate “the planning and expansion of transmission facilities
    to meet the reasonable needs of load-serving entities to satisfy
    [their] service obligations.” This section would only be violated
    if the Commission exercised its authority in a manner that was
    at odds with the needs of load-serving entities. Here, however,
    the Commission did no such thing. The ability of load-serving
    entities to meet their service obligations depends on their ability
    12
    A “load-serving entity” is a utility with an obligation
    created under law or contract to provide electricity service to end-use
    customers or to a distribution utility. 16 U.S.C. § 824q(a)(2)–(3).
    85
    to deliver power when it is needed. A failure to meet those
    obligations occurs when the utility must engage in practices
    such as rolling blackouts because of insufficient transmission
    capacity. Thus, Section 217(b)(4) requires the Commission to
    facilitate the planning of a reliable grid, which is exactly what
    the Commission has done in the challenged orders. The orders
    seek to ensure that adequate transmission capacity is built to
    allow load-serving entities to meet their service obligations. See
    Order 1000 ¶¶ 44–46, 76 Fed. Reg. at 49,851; Order 1000-A
    ¶¶ 170, 173, 77 Fed. Reg. at 32,213. The Commission has
    therefore “facilitate[d]” the planning of a more reliable grid and
    thus complied with the dictates of Section 217(b)(4).
    Petitioners also appear to make a separate argument that the
    Commission acted arbitrarily and capriciously by abandoning
    without explanation a previous interpretation of Section
    217(b)(4). According to petitioners, the Commission previously
    held that Section 217(b)(4) requires a categorical preference for
    load-serving entities, which it failed to incorporate into the
    challenged orders. They cite Order No. 681, in which the
    Commission concluded that Section 217(b)(4) creates a “general
    ‘due’ preference for load serving entities to obtain long-term
    firm transmission service.” See Long-Term Firm Transmission
    Rights in Organized Electricity Markets, F.E.R.C. Stats. & Regs.
    ¶ 31,226, at ¶ 320, 71 Fed. Reg. 43,564, 43,597 (2006). But we
    defer to the Commission’s reasonable interpretation of Order
    No. 681, see Indiana Util. Regulatory Comm’n v. FERC, 
    668 F.3d 735
    , 740 (D.C. Cir. 2012), and the Commission explains in
    the challenged orders that Order No. 681 did not establish that
    Section 217(b)(4) creates a preference for load-serving entities
    in the “broader context of planning new transmission capacity.”
    Order 1000-A ¶ 171, 77 Fed. Reg. at 32,213 (emphasis added).
    Instead, the Commission says, Order No. 681 established a
    preference for load-serving entities only with regard to existing
    capacity. 
    Id. This interpretation
    is reasonable. So limited,
    86
    Order No. 681 is not inconsistent with Order No. 1000 regarding
    the meaning of Section 217(b)(4). See Order 1000-A ¶¶ 171–72,
    77 Fed. Reg. at 32,213.
    C.
    Petitioners also argue that the orders’ public policy mandate
    is too vague, complaining that transmission providers will have
    great difficulty discerning exactly what the orders require of
    them. Their chief concern is that the Commission did not
    provide guidance on how regions should weigh and reconcile
    competing public policy requirements.
    But petitioners’ attack is once again based on a
    misunderstanding of the orders. The orders merely require
    regions to establish processes for identifying and evaluating
    public policies that might affect transmission needs. See Order
    No. 1000 ¶¶ 205–11, 214–16, 76 Fed. Reg. at 49,877–79; Order
    No. 1000-A ¶¶ 318, 327–29, 332–33, 77 Fed. Reg. at 32,234–36.
    The regions are free to choose their own manner of determining
    how best to identify and accommodate these policies. Our
    precedent makes clear that the Commission’s choice to afford
    regions such broad discretion does not render its mandate
    impermissibly vague. See Am. Exp.-Isbrandtsen Lines, Inc. v.
    Fed. Mar. Comm’n, 
    389 F.2d 962
    , 967 (D.C. Cir. 1968). In
    American Export, the petitioners argued that an agency order
    directing them to modify certain parts of their tariffs was void
    for vagueness because it left “unanswered such questions as:
    What will be the measure of damages and what sort of tribunal
    will fix them? What is an unusual delay? Who shall have the
    burden of proof of causation?” 
    Id. “Despite these
    questions,”
    however, the court found “no legitimate basis for complaint
    about the order’s indefiniteness.” 
    Id. Instead, the
    court
    suggested that the “petitioners should welcome the leeway and
    flexibility the Commission has given them in framing a . . . rule.
    Any vagueness in the Commission’s order should make
    87
    compliance with it that much easier. . . . It hardly behooves
    them to complain that they have been left too many options in
    undertaking this task.” 
    Id. Likewise, here,
    allowing regional
    flexibility does not make the mandate impermissibly vague.
    Utilities must come up with a procedure for evaluating needs
    driven by public policy, just as they evaluate needs driven by
    economic and reliability concerns. The details of the procedure,
    and how the utilities consider or weigh different needs, are left
    to their discretion.
    To show that the public policy mandate has sown confusion,
    petitioners point to tariffs rejected by the Commission for failure
    to comply with this requirement. But the Commission found no
    fault in the adequacy of the utilities’ procedures; the
    Commission rejected the tariffs because they failed to include,
    in certain respects, any procedures at all. See, e.g., S. Carolina
    Elec. & Gas Co., 143 F.E.R.C. ¶ 61,058 at ¶ 119 (2013) (“While
    SCE&G states in its transmittal letter that proposed transmission
    solutions to address transmission needs driven by public policy
    requirements will be evaluated in the same open and
    nondiscriminatory manner as other proposed regional
    transmission solutions for purposes of cost allocation, such
    information is not set forth in its tariff.” (footnote omitted));
    NorthWestern Corp., 143 F.E.R.C. ¶ 61,056 at ¶ 84
    (“NorthWestern has not established actual procedures in its
    OATT to identify at the regional level those transmission needs
    driven by public policy requirements for which potential
    transmission solutions will be evaluated. For example, it is not
    clear in NorthWestern’s OATT when and how stakeholders can
    propose transmission needs driven by public policy
    requirements for potential evaluation in the . . . regional
    transmission planning process.”). Rejection of tariffs that
    utterly fail to establish the procedures required by the public
    policy mandate tells us nothing about whether the mandate is
    impermissibly vague.
    88
    We find all of the challenges to the public policy mandate
    to be without merit and thus uphold the mandate.
    VII.
    Reciprocity. Petitioners raise two challenges to the Final
    Rule’s reciprocity condition. The reciprocity principle,
    instituted by the Commission in the Final Rule and two prior
    orders, requires non-public utility transmission providers that
    choose to access a public utility’s transmission lines to provide
    in exchange “reciprocal” transmission service, that is, service
    provided on comparable terms. See Order No. 1000 ¶¶ 818–19,
    76 Fed. Reg. at 49,961; Order No. 890 ¶¶ 162–192, 72 Fed. Reg.
    at 12,290–94; Order No. 888 at pp. 31,690–92, 61 Fed. Reg. at
    21,541–42. The Final Rule includes as part of the reciprocity
    condition that non-public utilities must participate in
    transmission planning and cost allocation in exchange for open
    access. Order No. 1000 ¶¶ 818–19, 76 Fed. Reg. at 49,961.
    Two groups of petitioners attack the Rule’s reciprocity
    condition on nearly opposite grounds. The Joint Petitioners
    argue that the Commission changed course from past practice
    without reasoned explanation by expanding the previous
    reciprocity condition to include planning and cost allocation
    requirements. The Edison Electric Institute (“Edison”), by
    contrast, contends that the Commission did not go far enough.
    Edison claims that the Commission acted arbitrarily and
    capriciously by allowing non-public utilities to participate
    voluntarily in the planning and cost allocation requirements of
    the orders, whereas Edison contends their participation should
    be mandatory. In particular, Edison asserts that the Commission
    should have invoked its power under Section 211A of the FPA
    to require non-public utility participation. Both contentions
    miss the mark.
    89
    The reciprocity condition before us is fundamentally the
    same as that contained in two prior Commission orders, Order
    Nos. 888 and 890. None requires non-public utilities to take any
    particular action. But all require such utilities, if they choose to
    take transmission service from a public utility, to provide
    reciprocal transmission service on comparable terms. The
    current orders simply apply that principle to transmission
    planning and cost allocation, such that any utility drawing from
    a public utility’s transmission lines must participate in planning
    and cost allocation processes. The Commission provided a
    reasoned and adequate basis for doing so, and was not arbitrary
    or capricious in deciding to stop at a conditional rather than a
    categorical requirement for non-public utilities. Section 211A
    does not require the Commission to mandate non-public utility
    participation in planning and cost allocation, and the
    Commission reasonably declined invoke its Section 211A
    authority to adopt such a mandate in favor of the order’s
    incremental and incentive-based approach.
    A.
    The Commission first established the reciprocity condition
    in Order No. 888 as part of its “ambitious program of market-
    based reforms.” Morgan 
    Stanley, 554 U.S. at 535
    . As
    previously discussed, Order No. 888 required each transmission
    provider to file a pro forma OATT offering transmission service
    to all customers on an equal basis. In efforts to further open
    access to transmission services, the Commission established
    that, when non-public utilities use the open public lines, they are
    subject to the same conditions as public utilities. See Order No.
    888 at p. 31,760, 61 Fed. Reg. at 21,613 (stating that “[a]ny
    public utility that offers non-discriminatory open access
    transmission for the benefit of customers should be able to
    obtain the same non-discriminatory access in return”). That
    reciprocity condition, which is carried forward in Order Nos.
    890 and 1000, appears in section 6 of the pro forma OATT and
    90
    authorizes public utilities to refuse to offer non-public utilities
    access unless the non-public utilities reciprocate by “agree[ing]
    to provide comparable transmission service to” the transmission-
    providing public utilities “on similar terms and conditions.” 
    Id. app. D
    Pro Forma OATT § 6, 61 Fed. Reg. at 21,710; see also
    Order No. 890 ¶ 163, 72 Fed. Reg. at 12,290.
    Non-public utilities are not subject to Section 206 of the
    FPA, and so are not directly governed by Order No. 1000 and its
    planning and cost allocation requirements. By conditioning
    non-public utilities’ access to the open systems of public utilities
    on the former’s adherence to the planning and cost allocation
    requirements, however, the Final Rule encourages non-public
    utilities to participate in planning and cost allocation. See Order
    No. 1000-A ¶ 773, 77 Fed. Reg. at 32,301 (“[T]hose [including
    non-public utilities] that ‘take advantage of open access,
    including improved transmission planning and cost allocation,
    should be expected to follow the same requirements as public
    utility transmission providers.’” (quoting Order No. 1000 ¶ 818,
    76 Fed. Reg. at 49,961)).
    In proposing that reciprocity condition, the Commission
    explained that, under Order No. 890, both public and non-public
    utilities had collaborated in a number of regional transmission
    planning processes. Encouraged by that collaboration, the
    Commission employed that voluntary and incentive-based
    approach in the orders now under review. NPRM ¶ 43, 75 Fed.
    Reg. at 37,890; see also Order No. 1000 ¶ 815, 76 Fed. Reg. at
    49,960. The Commission concluded that it was not “necessary
    at this time to invoke [the] authority under FPA section 211A,
    which allows [the Commission] to require non-public utility
    transmission providers to provide transmission services on a
    comparable and not unduly discriminatory or preferential basis.”
    NPRM ¶ 43, 75 Fed. Reg. at 37,890; see also Order No. 1000
    ¶ 815, 76 Fed. Reg. at 49,960. Instead, it chose to wait to
    91
    “exercise its authority under FPA section 211A on a case-by-
    case basis” if it “finds on the appropriate record that non-public
    utility transmission providers are not participating in the
    regional transmission planning and cost allocation processes.”
    NPRM ¶ 43, 75 Fed. Reg. at 37,890; see also Order No. 1000 ¶
    815, 76 Fed. Reg. at 49,960.
    In justifying the revised reciprocity condition, the
    Commission explained that:
    [N]on-public utility transmission providers will benefit
    greatly from the improved transmission planning and
    cost allocation processes required for public utility
    transmission providers because a well-planned grid is
    more reliable and provides more available, less
    congested paths for the transmission of electric power
    in interstate commerce. Those that take advantage of
    open access, including improved transmission planning
    and cost allocation, should be expected to follow the
    same requirements as public utility transmission
    providers.
    Order No. 1000 ¶ 818, 76 Fed. Reg. at 49,961.
    In Order No. 1000-A, the Commission denied rehearing on
    Order No. 1000’s reciprocity requirement, again emphasizing
    that the reciprocity requirement it adopted was unchanged from
    that in Order Nos. 888 and 890. Order No. 1000-A ¶¶ 754, 771,
    77 Fed. Reg. at 32,297–98, 32,300.
    B.
    The Joint Petitioners challenge the reciprocity condition,
    urging that the Commission expanded it beyond prior orders,
    without reasoned explanation, by including within it the
    92
    planning and cost allocation requirements.        We reject this
    contention.
    The requirement of reciprocity in the Final Rule is the same
    as in the prior orders. The Final Rule changes the condition
    only by altering the substantive requirements of the pro forma
    OATT, centrally by requiring public utilities to engage in
    transmission planning and cost allocation. As noted above, it
    does not require non-public utilities to take any action unless
    they choose to obtain transmission service from a public utility.
    Order No. 1000 ¶ 819, 76 Fed. Reg. at 49,961.
    The Joint Petitioners contend that the previous orders
    limited a non-public utility’s reciprocity obligation to the public
    utility that provided it with transmission access, and that the
    orders here impermissibly alter that scope without reasoned
    basis. The Joint Petitioners misconstrue the prior orders as
    limiting reciprocity to two utilities—a non-public utility and the
    public utility from which it takes transmission. The prior orders
    were not as narrowly bilateral as the Joint Petitioners assert.
    Instead, Order No. 890 required non-public utilities that were
    either members of, or took transmission service from, a power
    pool, Regional Transmission Group (“RTG”), RTO, ISO, or
    other such group to provide in return comparable services to all
    members of such groups. Order No. 890 app. C Pro Forma
    OATT § 6, 72 Fed. Reg. at 12,509; see also Order No. 888 app.
    D Pro Forma OATT § 6, 61 Fed. Reg. at 21,710; 
    id. at p.
    31,760, 61 Fed. Reg. at 21,613 (Order No. 888’s reciprocity
    condition required reciprocal transmission to any power pool or
    RTG of which the non-public utility was a member). And Order
    No. 890 explicitly determined that comparable service for
    reciprocity purposes includes compliance with the transmission
    planning reforms instituted by Order No. 890. See Order No.
    890 ¶ 441, 72 Fed. Reg. 12,321; Order No. 890-A ¶ 214,
    Preventing Undue Discrimination and Preference in
    93
    Transmission Service, 73 Fed. Reg. 2984, 3008–09 (2008)
    (stating on rehearing that a non-public utility with reciprocity
    obligations that does not adopt a planning process that complies
    with Order No. 890 may be at risk of being denied open access
    transmission services by public utilities); see also NPRM ¶ 10,
    75 Fed. Reg. at 37,886. The Final Rule’s reciprocity condition
    was not the radical swerve the Joint Petitioners decry.
    The Final Rule did change the requirements for public
    utilities—by requiring both transmission planning and cost
    allocation—and in so doing altered what constitute comparable
    terms for non-public utilities that choose to seek Commission-
    jurisdictional transmission service. See Order No. 1000-A ¶
    776, 77 Fed. Reg. at 32,301 (“Order No. 1000 applied the
    reciprocity provisions of Order Nos. 888 and 890 to provide that
    . . . a public utility transmission provider [may] refuse to offer
    open access transmission service to any non-public utility
    transmission provider that does not provide comparable
    reciprocal transmission service insofar as it is capable of doing
    so, including regional planning and cost allocation.”). Even if
    we were to view the Commission’s alteration of what constitutes
    comparable service under the pro forma OATT as a change in
    course, however, the agency acknowledged that it was altering
    the content of the reciprocal obligations. See, e.g., 
    id. And the
    Commission provided an adequate justification for that
    change—namely, that non-public utilities that take service from
    public utilities will benefit greatly from the reforms announced
    in the Final Rule, because “a well-planned grid is more reliable
    and provides more available, less congested paths for the
    transmission of electric power in interstate commerce.” 
    Id. ¶ 778,
    77 Fed. Reg. 32,301.
    In sum, the Commission’s adoption of the reciprocity
    condition in the Final Rule fully complied with the requirement
    that an agency “display awareness that it is changing
    94
    position[s]” and “show that there are good reasons for the new
    policy.” FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515
    (2009).
    C.
    Petitioner Edison, by contrast, takes the position that the
    Commission has authority under Section 211A of the FPA to
    mandate that non-public utilities comply with the Final Rule,
    including its regional planning and cost allocation requirements,
    and that the agency acted arbitrarily and capriciously in failing
    to so mandate. We reject that contention as well.
    In Edison’s view, “[w]ithout a mandate to participate, non-
    public utility transmission providers will receive the[] benefits
    [of transmission planning and new facilities] without being
    assessed commensurate costs.” Initial Br. of Pet’r Concerning
    FPA § 211A at 5 (“Edison Br.”). Edison argues that “[t]he
    record demonstrates” that non-public utility transmission
    providers will not in fact voluntarily participate in transmission
    planning or cost allocation. 
    Id. at 7.
    In support, Edison cites
    comments by non-public utilities to the effect that they are
    committed to participating in the planning and cost allocation
    processes but cannot commit to being bound by the building
    expansion programs that may result because those programs
    have not yet been determined. 
    Id. According to
    Edison, the
    Commission must therefore mandate the participation of non-
    public utilities under Section 211A of the FPA, and its failure to
    do so was arbitrary and capricious.
    Section 211A(b) of the FPA provides in relevant part:
    [T]he Commission may, by rule or order, require an
    unregulated transmitting utility to provide transmission
    services—
    (1) at rates that are comparable to those that the
    unregulated transmitting utility charges itself; and
    95
    (2) on terms and conditions (not relating to rates) that
    are comparable to those under which the unregulated
    transmitting utility provides transmission services to
    itself and that are not unduly discriminatory or
    preferential.
    16 U.S.C. § 824j-1(b).
    Congress’ use of the word “may” in Section 211A plainly
    permits, but does not mandate, the Commission to require a non-
    public utility to provide transmission service on given terms.
    See, e.g., Wagner v. FEC, 
    717 F.3d 1007
    , 1012 (D.C. Cir. 2013);
    McCreary v. Offner, 
    172 F.3d 76
    , 83 (D.C. Cir. 1999). As such,
    the statute does not require the Commission to go as far as
    Edison urges.
    The Commission, moreover, adequately explained that its
    past successful experience with voluntary participation under
    Order No. 890 led to its decision to take a conditional incentive-
    based approach to reciprocity in planning and cost allocation, at
    least at this juncture. Order No. 1000 ¶ 815, 76 Fed. Reg. at
    49,960. The Commission thus articulated a satisfactory
    explanation for its predictive judgment that non-public utilities
    are likely to participate voluntarily, and we owe that judgment
    deference. “‘[I]t is within the scope of the agency’s expertise to
    make . . . a prediction about the market it regulates, and a
    reasonable prediction deserves our deference notwithstanding
    that there might also be another reasonable view.’”
    Constellation Energy Commodities Grp., Inc. v. FERC, 
    457 F.3d 14
    , 24 (D.C. Cir. 2006) (ellipses in original) (quoting Envtl.
    Action, Inc. v. FERC, 
    939 F.2d 1057
    , 1064 (D.C. Cir. 1991)).
    The evidence that Edison cites for the proposition that non-
    public utilities will not participate does not “flatly contradict[]”
    the Commission’s conclusion. Edison Br. 7. Edison points to
    comments from non-public utilities expressing concerns about
    mandatory cost allocation, but those comments do not
    96
    contravene the Commission’s judgment that such utilities are
    likely to participate in planning and cost allocation when it is a
    condition of access to public transmission service.
    Nor was the Commission’s approach arbitrary and
    capricious because it “creates undue discrimination” between
    public and non-public utilities. Edison Br. 10. Edison
    complains the Rule foists the costs of new facilities on regulated
    public utilities while giving non-public utilities a free ride. The
    Commission was under no statutory obligation to regulate non-
    public utilities, and it provided a reasoned basis for choosing a
    conditional approach, grounded in a prediction that non-public
    utilities would in fact participate, and leaving for another day
    whether to require non-public utilities’ participation pursuant to
    its Section 211A authority. Order No. 1000 ¶ 815, 76 Fed. Reg.
    at 49,960.
    The Commission’s decision to adopt a reciprocity condition
    embracing voluntary and incentive-based participation by non-
    public utilities was accordingly neither arbitrary nor capricious.
    We therefore need not reach whether the Commission has
    authority under Section 211A to mandate the participation of
    non-public utilities.
    Edison additionally contends that the Commission acted
    arbitrarily and capriciously by failing to respond adequately to
    its arguments to the Commission on rehearing. That contention,
    too, is without merit.         Following the Commission’s
    announcement in the Notice of Proposed Rulemaking that it
    planned to use a voluntary approach, a number of commenters
    raised materially identical arguments to those Edison raised in
    its request for rehearing. Compare Order No. 1000 ¶ 812, 76
    Fed. Reg. at 49,960 (summarizing comments asserting that the
    Commission has authority to require non-public utilities’
    participation under Section 211A and that its failure to do so
    “will result in an inequitable burden for jurisdictional utilities
    97
    and their customers”) and 
    id. ¶¶ 815,
    817–18, 821, 76 Fed. Reg.
    at 49,960–61 (responding to those concerns), with Order No.
    1000-A ¶¶ 767–70, 77 Fed. Reg. at 32,299–300 (summarizing
    Edison’s comment that the Commission “erred by relying on
    non-public utility transmission providers to voluntarily
    participate in regional transmission planning and cost allocation
    processes” instead of exercising its authority under Section
    211A). “While an agency must consider and explain its
    rejection of ‘reasonably obvious alternative[s],’ it need not . . .
    respond to every comment made. Rather, an agency must
    consider only ‘significant and viable’ and ‘obvious’
    alternatives.” Nat’l Shooting Sports Found., Inc. v. Jones, 
    716 F.3d 200
    , 215 (D.C. Cir. 2013) (brackets in original) (citations
    omitted).      The Commission adequately addressed the
    commenters’ concerns that voluntary participation by non-public
    utilities would undermine the Commission’s objectives and
    sufficiently explained its reasons for declining, at that time, to
    require non-public utility compliance under Section 211A.
    For these reasons, we reject the challenges to the reciprocity
    condition.
    Accordingly, we deny the petitions for review.
