    SENTELLE .
    PILLARD , Circuit Judge: Three electrical transmission
    companies, subsidiaries of the same parent company, petition
    for review of a decision by the Federal Energy Regulatory
    Commission (FERC) to reduce the enhanced return on equity
    FERC had previously authorized them to collect from
    ratepayers due to their status as standalone transmission
    companies. FERC calls such companies Transcos. Since 2003
    it has granted return-on-equity “adders” to Transcos because of
    what the Commission had concluded was a willingness and
    ability on their part to invest in transmission infrastructure—a
    policy objective that Congress endorsed in 2005 when it
    required FERC to formally establish incentive-based rate
    treatments for transmission companies. FERC consistently has
    premised companies’ eligibility for “Transco adders” on their
    standalone transmission status, which it has evaluated by
    looking to the companies’ ability to maintain operational
    3
    independence from other participants in the electrical market,
    such as companies invested in power generation.
    In 2016, two foreign-based companies with holdings in
    U.S. electrical markets acquired the parent company of the
    three petitioners. A group of transmission customers formally
    complained to FERC that the petitioners’ existing return-on-
    equity adders were no longer just and reasonable because the
    companies, post-merger, were no longer independent. FERC
    found the merger had reduced but not eliminated the three
    Transcos’ independence from other market participants and,
    based on that finding, reduced the adders at issue by half.
    Petitioners argue on appeal that, in so doing, FERC arbitrarily
    departed from a particular methodology for determining
    independence that they say FERC precedent requires. They
    claim that, under that methodology, they remained materially
    independent so the reductions were unjustified. They also
    argue that FERC exceeded its statutory authority by not
    expressly finding the existing adders unlawful before setting
    them at a new level. We conclude that neither claim has merit
    so deny the petition in full.
    BACKGROUND
    A. Regulatory Context
    In 2005, Congress amended the Federal Power Act to
    require FERC to take action within the year to promulgate a
    rule to establish “incentive-based . . . rate treatments for the
    transmission of electric energy,” that is, for the bulk movement
    of electricity across electrical grids. See Energy Policy Act of
    2005, Pub. L. No. 109-58, § 1241, 
    119 Stat. 594
    , 961 (codified
    as amended at 16 U.S.C. § 824s). Congress’s stated purpose
    was to “benefit[] consumers by ensuring reliability and
    reducing the cost of delivered power by reducing transmission
    congestion.” 16 U.S.C. § 824s(a). Congestion in the grid arises
    4
    when the demand for electricity exceeds the capacity of
    existing transmission infrastructure. That results in a grid that
    cannot accommodate consumer demand in certain areas
    through the transmission of low-cost generation, forcing the
    grid to instead draw on more expensive generation closer to the
    areas of high demand, which ultimately raises costs to
    consumers. Congress legislated in 2005 “against the backdrop
    of declining investment in transmission infrastructure and
    increasing electric load”—a combination ripe for transmission
    congestion. Promoting Transmission Investment Through
    Pricing Reform, Notice of Proposed Rulemaking, 
    113 FERC ¶ 61,182
     at P1 (2005). It intended the incentive-based rate
    treatments to help alleviate that problem by encouraging
    investments in transmission infrastructure, thereby improving
    the transmission system’s capacity and reliability. See San
    Diego Gas & Elec. Co. v. FERC, 
    913 F.3d 127
    , 130 (D.C. Cir.
    2019).
    The implementing rule FERC promulgated the following
    year established a series of categories of incentive-based rate
    treatments for public utilities. See 
    18 C.F.R. § 35.35
    (d). Two
    of these incentives were limited to standalone transmission
    companies, meaning companies that deal exclusively in the
    transmission of electricity, not its generation.               
    Id.
    §§ 35.35(b)(1), (d)(2). Under the incentive at issue in this case,
    FERC will authorize “[a] return on equity that both encourages
    Transco formation and is sufficient to attract investment” in
    transmission facilities and related technologies.              Id.
    § 35.35(d)(2)(i); see 16 U.S.C. § 824s(b)(2).
    The 2006 rule was the first codification of that incentive,
    but it reflected a preexisting FERC practice of granting
    independent and standalone transmission companies “adders”
    to their base return on equity. As its name suggests, a FERC-
    authorized return on equity determines the extent to which a
    5
    utility in the highly regulated electricity sector may earn a
    profit.     FERC ties “adders” to certain behaviors or
    characteristics of utilities, incentivizing needed actions by
    bumping up their returns on equity above the base level set by
    FERC. The first “Transco adders” were granted in 2003 to
    International Transmission Company and Michigan Electric
    Transmission Company (METC), two of the petitioners in this
    case. ITC Holdings Corp., 
    102 FERC ¶ 61,182
     (2003); METC,
    
    105 FERC ¶ 61,214
     (2003); see also METC, 
    113 FERC ¶ 61,343
     (2005).1 Each adder was worth 100 basis points, an
    amount equal to a single percentage point.
    FERC’s stated reason for codifying the Transco adder as
    one of several available incentives was Transcos’ positive track
    record of investing in transmission infrastructure. It explained
    that the three Transcos to which it had previously granted such
    adders, including petitioners International Transmission and
    METC, had “demonstrated the capability to invest, on a timely
    basis, significant amounts of capital in transmission projects
    and in efforts to reduce congestion.” Promoting Transmission
    Investment Through Pricing Reform, Notice of Proposed
    Rulemaking, 
    113 FERC ¶ 61182
     at P38. FERC concluded that
    their positive investment record was “related to the stand-alone
    nature of these entities,” explaining that “[b]y eliminating
    competition for capital between generation and transmission
    functions and thereby maintaining a singular focus on
    transmission investment, the Transco model responds more
    rapidly and precisely to market signals indicating when and
    where transmission is needed.” Promoting Transmission
    Investment Through Pricing Reform, Order No. 679, 
    116 FERC ¶ 61,057
     at P224 (2006) (Order No. 679). In addition,
    because Transcos deal only in transmission, they “provide non-

    6
    discriminatory access to all grid users.” 
    Id.
     Independent
    Transcos “have no incentive to maintain congestion in order to
    protect their owned generation”—a situation that might arise,
    for example, with an integrated utility whose highest-cost
    generation is brought on line when congestion impedes access
    to lower-cost power. 
    Id.
     FERC was careful to note that a
    Transco would be allowed an adder over the long term only if
    it “continue[d] to provide the benefits which we are trying to
    incentivize.” 
    Id.
     at P226.
    Since 2003, FERC has weighed a Transco’s ownership and
    business structure in the course of deciding whether to grant a
    requested Transco adder. FERC emphasized from the outset
    that “[i]ndependent ownership and operation of transmission is
    an important policy objective of the Commission,” citing
    among the benefits of independence the “lessened potential for
    discrimination, improved access to capital markets for
    transmission investment, improved asset management, and
    development of innovative services.” METC, 
    105 FERC ¶ 61,214
     at P20; see also ITC Holdings Corp., 
    102 FERC ¶ 61,182
     at P68. FERC assessed the Transcos’ ability to operate
    independently from market participants—entities that sell
    generation or other services that could be affected by a
    Transco’s actions and thus might bear on investment decisions.
    In 2003, International Transmission was indirectly owned
    by a limited partnership, so in assessing International
    Transmission’s independence FERC considered the roles and
    affiliations of the owner’s general and limited partners. See
    ITC Holdings Corp., 
    102 FERC ¶ 61,182
     at PP39-44. The
    Commission determined the general partners were of little
    concern because they lacked financial ties to market
    participants and that, while the limited partners had interests in
    generation holdings, they would nonetheless not affect
    International Transmission’s operational independence on
    7
    account of their limited voting rights in those other interests.
    
    Id.
     When International Transmission went public two years
    later, FERC continued to permit its adder on the condition that
    no market participant acquire more than five percent of the
    company’s stock. See ITC Holdings Corp., 
    111 FERC ¶ 61,149
    at PP18-26 (2005).
    Soon after that decision, FERC issued a policy statement
    clarifying its policy on Transco independence.            The
    Commission announced that Transcos with “market
    participants as passive minority equity owners” were
    permissible. Policy Statement Regarding Evaluation of
    Independent Ownership & Operation of Transmission, 
    111 FERC ¶ 61,473
     at PP1-2 (2005). It underscored, however, that
    it would evaluate rate proposals “to ensure that passive
    ownership does not affect the independent operation, planning
    and construction of their transmission system.” 
    Id.
    FERC continued its practice of evaluating Transco
    independence when it codified the Transco adder in 2006.
    FERC defined a Transco as simply a standalone transmission
    company, “regardless of whether it is affiliated with another
    public utility.” Order No. 679, 
    116 FERC ¶ 61,057
     at P201. In
    so doing, the Commission declined to “exclude affiliated
    Transcos with active ownership by market participants.” 
    Id.
     at
    P202. But the preamble to FERC’s 2006 rule stressed that their
    independence remained “an important component of the
    positive contribution of Transcos [to] investment in needed
    transmission infrastructure,” noting specifically that
    International Transmission and METC were “totally
    independent of market participants.” 
    Id.
     at P240; see also 
    id.
    at P202. FERC thus determined that it would “consider the
    level of independence of a Transco as part of [its] analysis” in
    determining “appropriate incentives.” 
    Id.
     at P239. It stated
    that a Transco with active ownership by market participants
    8
    could receive the adder “to the extent it can show, for example,
    why active ownership by an affiliate does not affect the
    integrity of its investment planning, capital formation, and
    investment processes or how its business structure provides
    support for transmission investments in a way similar to the
    structure of non-affiliated Transcos or Transcos with only
    passive ownership by market participants.” 
    Id.
     at P240.
    Since codifying the Transco adder in 2006, FERC has
    granted it to twelve entities. See Electric Transmission
    Incentives Policy Under Section 219 of the Federal Power Act,
    Notice of Proposed Rulemaking, 
    170 FERC ¶ 61,204
     at P90 &
    n.106 (2020). One of the twelve is the third petitioner in this
    case, ITC Midwest. See Midcontinent Indep. Sys. Operator,
    Inc., 
    150 FERC ¶ 61,252
     (2015). FERC found ITC Midwest
    to be “fully independent” but, unlike in earlier cases, granted
    the Transco a 50—instead of 100—basis point adder. 
    Id.
     at
    P45. It concluded that its earlier decisions granting 100 basis
    points were “based on the specific circumstances of the
    applicants and market conditions at the time of their
    applications” and determined that 100 basis points was
    “excessive for the Transco Adder at this time.” 
    Id.
     FERC has
    since recognized 50 basis points to be presumptively the
    appropriate size for a Transco adder.2
    2
    In a notice of proposed rulemaking published in 2020, FERC
    proposes eliminating the Transco adder entirely. See Electric
    Transmission Incentives Policy Under Section 219 of the Federal
    Power Act, Notice of Proposed Rulemaking, 
    170 FERC ¶ 61,204
    . It
    states “that the circumstances have changed significantly since Order
    No. 679,” that “the key reasoning underpinning [FERC’s] policy . . .
    no longer appl[ies],” and that “the Transco business model has not
    enhanced the deployment of transmission infrastructure sufficiently
    to justify incentives based on this business model beyond those

    B. Administrative Proceedings
    ITC Holdings is the parent company of the three
    petitioners in this case.3 All three are members of the
    Midcontinent     Independent       System    Operator,     Inc.
    (Midcontinent Region), a regional transmission organization.
    A regional transmission organization is a FERC-approved
    non-profit, independent organization that administers the grid
    on a regional basis on behalf of transmission-owning member
    utilities. The Midcontinent Region operates in the Eastern
    Interconnection, one of the three major electrical grids in the
    continental United States.      The Midcontinent Region’s
    geographic footprint encompasses Manitoba, Canada, and
    extends south across fifteen U.S. states, most of which are in
    the Midwest, with a few in the South.
    In 2016, ITC Holdings was acquired by Fortis, Inc., and
    GIC (Ventures) Private Limited in a merger transaction
    authorized by FERC. See Fortis Inc., 
    156 FERC ¶ 61,219
    (2016). Fortis is a Canadian holding corporation whose
    holdings include electric distribution and natural gas utilities in
    the United States. GIC Ventures is an investment company
    indirectly owned by the government of Singapore. As a result
    of the merger transaction, Fortis now owns 80.1 percent of ITC
    Holdings and GIC Ventures owns the remaining 19.9 percent.
    incentives available to all public utilities.” 
    Id.
     at P90-91. FERC
    noted that “the Transco business model that the Commission
    envisioned in approving Transco incentives . . . was one of robust
    independence,” but that, “currently, the majority of Transcos have
    started out as, or become, transmission affiliates of integrated
    utilities.” 
    Id.
     at P90.
    3
    ITC Holdings acquired METC in 2006, after METC had been
    granted a Transco adder. See ITC Holdings Corp., 
    116 FERC ¶ 61,271
     (2006).
    10
    Both Fortis and GIC Ventures have representatives on ITC
    Holdings’ board.
    After the merger, a group of ITC Holdings transmission
    customers—including companies involved in the generation,
    distribution, and retail sale of electricity and organizations of
    municipal utilities—filed a complaint with FERC under
    Section 206 of the Federal Power Act asserting that the three
    adders held by the petitioners in this case, worth approximately
    $24 million in annual revenues, were no longer just and
    reasonable, as required by the Federal Power Act. 16 U.S.C.
    § 824d(a). As a result of the merger, the three ITC subsidiaries
    (collectively, ITC) were affiliated with market participants that
    generate, purchase, and/or sell electricity in the Eastern
    Interconnection. The complainants argued that petitioners’
    independence could be affected by ITC’s operations, so
    petitioners were no longer entitled to an incentive reserved for
    independent Transcos.
    The complainants identified two Fortis subsidiaries that
    generate, purchase, and sell electricity over the Eastern
    Interconnection grid—one in Ontario, which borders the
    Midcontinent Region, and the other in New York. And they
    identified two GIC Ventures subsidiaries that operate in PJM,
    a regional transmission organization that covers much of the
    Rust Belt region and that borders the Midcontinent Region in
    the Midwest. One of those GIC Ventures subsidiaries markets
    and sells electricity in and around Pittsburgh, and the other
    owns generation close to the Midcontinent Region, in Illinois,
    Michigan, and Ohio. Explaining how the affiliates might
    compromise ITC’s independence, the complainants noted that
    Fortis’s subsidiaries operate on an integrated basis, raising the
    risk, for example, that ITC could make transmission decisions
    biased in favor of the Ontario and New York companies. They
    contended that the three Transcos’ membership in the
    11
    Midcontinent Region, which, like all regional transmission
    organizations, is itself required to be independent from market
    participants and collectively oversees the transmission
    operations of its members, was insufficient to guard against the
    risks posed by ITC’s lack of independence. The consumers
    argued that the adder’s “entire point is the belief that ratepayers
    gain by placing transmission ownership in an entity that has no
    reason to even wish to discriminate for or against any subset of
    transmission users, in part because discrimination can take
    subtle forms that are difficult to detect and remedy.”
    Complaint at 10 (J.A. 69).
    In its answer to the complaint, ITC claimed that the
    complainants assumed the wrong level of analysis, arguing that
    participants’ status is appropriately assessed at the level of an
    individual regional transmission system, not across the entire
    Eastern Interconnection. ITC pointed out that neither GIC nor
    Fortis has subsidiaries in the Midcontinent Region’s markets.
    It asserted that it accordingly remained independent of the
    relevant market participants. As support, ITC cited FERC’s
    recent decision in NextEra Energy Transmission N.Y., Inc., 
    162 FERC ¶ 61,196
     (2018), which granted an adder to an Eastern
    Interconnection Transco even though its parent company
    owned 38,000 megawatts of generation in different regions
    within the Interconnection—generation holdings that ITC
    argued “dwarf[ed] the Fortis and GIC Ventures interests”
    identified by complainants. Answer at 18 (J.A. 179).
    Even if market-participant status were assessed on an
    Interconnection-wide basis, ITC argued, it maintained
    sufficient independence under criteria identified in Order No.
    679, FERC’s preamble to the 2006 rule, because its affiliations
    did not affect the integrity of its investment planning, capital
    formation, or investment processes. The ITC companies
    continued to plan their transmission operations through the
    12
    Midcontinent Region, free of influence from Fortis, GIC, or
    any affiliates; they established capital plans independently
    before they were used by Fortis management; and they
    maintained their own financing, funding their programs
    through debt issuances and equity infusions.
    In October 2018, FERC granted the complaint in part,
    finding that the merger had reduced ITC’s independence. It
    stated that Order No. 679 “established criteria for use in
    determining whether an entity with active ownership by a
    market participant is sufficiently independent to qualify for a
    Transco Adder,” including the criteria identified by ITC—an
    “entity’s ‘integrity of investment planning, capital formation,
    and investment processes’”—“‘as well as how its business
    structure provides support for transmission investments.’”
    Consumers Energy Co. v. Int’l Transmission Co., 
    165 FERC ¶ 61,021
     at P67 (2018) (Complaint Order) (quoting Order No.
    679, 
    116 FERC ¶ 61,057
     at PP239-40). FERC drew from
    Order No. 679 three specific criteria relevant to independence:
    investment planning, capital formation, and business structure.
    It assessed ITC’s post-merger status under each one.
    First, with regard to investment planning, FERC found that
    ITC “demonstrate[s] some level of independence by
    developing [its] own capital expansion plans.” 
    Id.
     at P69. But
    it also found that Fortis’s evaluation of “capital expenditures
    on a consolidated basis for its entire corporate family . . .
    indicate[s] . . . some level of coordination [with] and control”
    over ITC. 
    Id.
    Second, with regard to capital formation, FERC again
    noted that ITC “demonstrate[s] some level of independence in
    that [it] can issue [its] own debt independently from Fortis and
    GIC.” 
    Id.
     at P70. But Fortis’s annual report revealed that “ITC
    13
    Holdings can no longer issue its own common stock, and, to
    some degree, [ITC] rel[ies] on Fortis for financing.” 
    Id.
    Third, with regard to business structure, FERC yet again
    found that ITC “demonstrate[s] some level of independence”
    because the majority of ITC Holdings’ board of directors “is
    unaffiliated with Fortis and GIC.” 
    Id.
     at P71. But its
    independence was materially decreased because the
    representatives of Fortis and GIC on ITC Holdings’ Board
    “provide some oversight,” and executives across all of Fortis’s
    utility subsidiaries “meet[] regularly to discuss business
    operations.” 
    Id.
    In addition to those three criteria, FERC noted “certain
    minor potential conflicts of interest associated with other assets
    owned by Fortis and GIC.” 
    Id.
     at P72. But it concluded that
    “such concerns are largely attenuated by the location of such
    assets and the fact that they are largely subject to small
    ownership shares by Fortis and GIC.” 
    Id.
     It did not respond
    directly to ITC’s suggestion that, under NextEra, the location
    of those interests outside of the regional transmission
    organization by itself required a finding of continued
    independence. In the order’s recitals, however, FERC did note
    complainants’ efforts to distinguish NextEra. See 
    id.
     at P58.
    Complainants had argued that the ITC Transcos—“incumbent
    transmission owners of virtually all of the transmission
    facilities in their respective zones”—are materially different
    from the Transco in NextEra—“a new entrant to the relevant
    region, with ‘no transmission plant in service,’ and no
    established financial history to support external financing.”
    Reply at 13-14 (J.A. 274-75) (quoting NextEra, 
    162 FERC ¶ 61,196
     at P22). The NextEra Transco “sought a transco
    incentive for a single project, for which it was the non-
    incumbent developer selected through a competitive
    solicitation,” whereas the ITC companies were granted adders
    14
    “on the basis of their promised full independence from market
    participants.” Id. at 14 (J.A. 275).
    Considering the independence criteria in combination,
    FERC concluded that ITC’s independence had been materially
    reduced by the merger. Based on the reduced level of
    independence, it determined it was “appropriate to revisit the
    appropriate level” of its Transco adders. Complaint Order, 
    165 FERC ¶ 61,021
     at P73. Citing its decision granting ITC
    Midwest an adder in 2015, FERC stated that current policy was
    for “a fully independent transmission company” to receive a 50
    basis point adder. 
    Id.
     And “[b]ecause the merger ha[d]
    reduced, but not eliminated, [ITC’s] level of independence,”
    the Commission determined that a 25 basis point adder
    “appropriately encourages the Transco business model in these
    circumstances and promotes corresponding consumer
    benefits.” 
    Id.
    One Commissioner dissented, stating that he would have
    eliminated the adder entirely because ITC was no longer
    “sufficiently independent to justify” an adder at any level. 
    Id.
    (Glick, Comm’r, dissenting).
    ITC filed a request for rehearing before the Commission.
    It argued that FERC had failed to identify the applicable legal
    standard for independence, and had not explained whether the
    Fortis and GIC subsidiaries that its order suggested present
    “minor potential conflicts of interest” were properly considered
    market affiliates. Request for Rehearing at 7 (J.A. 293). It also
    argued that FERC departed without explanation from its most
    recent precedent granting Transco adders, NextEra and
    GridLiance West Transco LLC, 
    164 FERC ¶ 61,049
     (2018).
    ITC noted again the NextEra Transco’s generation holdings in
    the Eastern Interconnection, and added that the GridLiance
    Transco was controlled by a limited partnership whose
    15
    majority partner owned generation throughout the country. See
    Request for Rehearing at 10-11 (J.A. 296-97). ITC claimed
    that FERC had “offer[ed] no basis for treating [ITC] differently
    from” those Transcos. Id. at 10 (J.A. 296).
    FERC denied ITC’s request for rehearing in July 2019.
    Consumers Energy Co. v. Int’l Transmission Co., 
    168 FERC ¶ 61,035
     at PP 16-20 (2019) (Rehearing Order). The
    Commission first held that it had applied the appropriate
    independence standard, which it identified as the criteria
    described in Order No. 679. It disagreed with ITC’s suggestion
    that market affiliates outside the relevant regional transmission
    organization should not be considered at all, noting that Order
    No. 679 “places no geographic limitation on the scope of
    relevant affiliate relationships.” 
    Id.
     at P12. And it explained
    that its conclusion was consistent with NextEra, in which
    FERC deemed the Transco independent despite affiliates
    “located inside and outside” the relevant region. 
    Id.
     at P13
    (emphasis in original) (quoting NextEra, 
    162 FERC ¶ 61,196
    at P51).
    FERC then affirmed its conclusion that ITC was no longer
    fully independent after the merger, disagreeing with ITC that
    NextEra and GridLiance required a contrary conclusion.
    FERC noted that it found on the facts of both of those cases
    that those Transcos’ market affiliates “did not ‘affect the
    integrity of [the Transcos’] investment planning, capital
    formation, and investment processes.’” 
    Id.
     at P17 (quoting
    NextEra, 
    162 FERC ¶ 61,196
     at P51). ITC claimed it was more
    independent than the Transco in NextEra, the Commission
    noted, but failed to explain “how [it is] more independent.” 
    Id.
    at P20. “The Commission evaluates the independence of each
    Transco on a case-by-case basis based on each proceeding,”
    FERC explained, and “evidence in this record specifically
    demonstrate[d] that [ITC’s] affiliate relationships reduced the
    16
    independence of its invest[ment] planning, capital formation,
    investment processes, and business structure.” 
    Id.
    ITC petitioned us for review.
    DISCUSSION
    We uphold FERC’s final orders unless they are arbitrary
    or capricious, an abuse of discretion, or otherwise not in
    accordance with the law. FERC v. Elec. Power Supply Ass’n,
    
    136 S. Ct. 760
    , 782 (2016); NextEra Energy Res., LLC v.
    FERC, 
    898 F.3d 14
    , 20 (D.C. Cir. 2018). We review the
    Commission’s factual findings for substantial evidence. 16
    U.S.C. § 825l(b). “[I]n 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.’” S.C. Pub. Serv. Auth. v. FERC, 
    762 F.3d 41
    , 54
    (D.C. Cir. 2014) (quoting Alcoa Inc. v. FERC, 
    564 F.3d 1342
    ,
    1347 (D.C. Cir. 2009)).
    ITC’s petition raises two claims. First, it argues that FERC
    arbitrarily and capriciously departed from precedent
    establishing a particular methodology to assess Transco
    independence. Second, it argues that FERC exceeded its
    statutory authority by reducing ITC’s Transco adders without
    first finding the adders to be unjust and unreasonable. We
    consider each challenge in turn.
    A. Independence Analysis
    FERC expressly declined in Order No. 679 to “establish a
    specific methodology to factor the level of independence into
    any request for [return on equity]-based incentives for
    Transcos,” stating that it would instead “evaluate the specific
    attributes of a particular proposal, including the level of
    17
    independence, to determine appropriate incentives.” 
    116 FERC ¶ 61,057
     at P239. ITC nonetheless suggests that FERC
    established just such a methodology in two orders decided
    before this case: NextEra and GridLiance. In those cases,
    FERC granted the Transco adder after finding that the Transco
    at issue could operate independently of market affiliates inside
    and outside its transmission region. The analysis was similar
    in both: FERC noted that affiliates outside the relevant region
    “[were] distant from . . . and [did] not participate in [the
    regional system’s] markets” and that affiliated holdings inside
    the region were small and had the sale of their generation
    output committed under long-term contracts. GridLiance, 
    164 FERC ¶ 61,049
     at P43; accord NextEra, 
    162 FERC ¶ 61,196
     at
    P51. From these two cases ITC argues that FERC “established
    its methodology for applying Order No. 679’s general guidance
    to assess the independence of transmission subsidiaries that are
    part of corporate families that include some generation
    holdings.” Pet’rs Br. 21. According to ITC, under the
    NextEra/GridLiance methodology, FERC first categorizes
    affiliated holdings based on whether they are inside or outside
    the transmission region: Those outside have no effect on a
    Transco’s independence because they are geographically
    distant and outside the regional system’s markets, and those
    inside do not affect a Transco’s independence if they are small
    and their output is committed under long-term contracts. ITC
    claims FERC “departed without acknowledgment or
    explanation from its geographically focused methodology” in
    this case, instead applying “a new corporate-structure test.”
    Pet’rs Br. 22.
    ITC’s argument that FERC departed from an established
    methodology fails at the outset because FERC, consistent with
    its stated intent in Order No. 679, never established any
    definitive methodology, let alone the one ITC claims it did.
    FERC has consistently applied a case-by-case approach to
    18
    determining Transco independence, considering ownership
    and business structure as part of that inquiry since it first
    granted a Transco adder in 2003. When the adder was codified
    in 2006, Order No. 679 built on prior practice by identifying
    certain criteria that ITC now mistakenly claims constitute “a
    new corporate-structure test.”
    In Order No. 679, FERC extended eligibility for a Transco
    adder to “[a] transco with active ownership by a market
    participant . . . to the extent it can show, for example, why
    active ownership by an affiliate does not affect the integrity of
    its investment planning, capital formation, and investment
    processes or how its business structure provides support for
    transmission investments in a way similar to the structure of
    non-affiliated Transcos or Transcos with only passive
    ownership by market participants.” Order No. 679, 
    116 FERC ¶ 61,057
     at P240. FERC considered precisely those criteria in
    its order reducing ITC’s adders. It found that ITC was no
    longer fully independent based on a multi-factored assessment
    of its investment planning, capital formation, and business
    structure.
    The precedents that ITC argues established a different
    methodology in fact concluded that the Transcos were
    independent according to the Order No. 679 criteria. In
    NextEra, FERC held in the same paragraph from which ITC
    draws its test that, “[b]ased on the record here . . . [the Transco]
    has demonstrated that its relationship to its affiliated market
    participants will not affect the integrity of [its] investment
    planning, capital formation, and investment processes.” 
    162 FERC ¶ 61,196
     at P51. FERC then turned to the geographical
    facts presented on the NextEra record to inform that bottom-
    line finding. 
    Id.
     Its analysis in GridLiance was similar. FERC
    began there by noting it “found [the Transco] ha[d]
    demonstrated that its relationship to its affiliates will not affect
    19
    the integrity of [its] investment planning, capital formation, and
    investment processes.” 
    164 FERC ¶ 61,049
     at P43. Only then
    did it go on to consider the location and details of the Transco’s
    affiliated holdings. 
    Id.
     Nowhere in either decision did FERC
    suggest that the geographical factors it weighed in concluding
    that the Transcos at issue were independent were the only
    criteria to be considered under Order No. 679. Based on a plain
    reading of NextEra and GridLiance, and bolstered by the
    deference that we owe FERC in the interpretation of its own
    precedent, see Mo. Pub. Serv. Comm’n v. FERC, 
    783 F.3d 310
    ,
    316 (D.C. Cir. 2015), we conclude those decisions do not
    establish a methodology for assessing independence.
    ITC argues that our cases requiring that an agency provide
    a reasoned explanation when it departs from precedent demand
    vacatur here. But because FERC adopted no exclusively
    “geographically focused methodology” from which to depart,
    FERC had no obligation to explain specifically why its inquiry
    here was broader. West Deptford Energy, LLC v. FERC, 
    766 F.3d 10
     (D.C. Cir. 2014), one of the cases on which ITC relies,
    illustrates the difference. The issue in West Deptford was
    which tariff governs an “interconnection agreement” between
    a generator and a regional transmission organization when the
    organization’s tariff is amended in the course of a generator
    seeking access to the organization’s network—the tariff in
    place when the generator’s request is first made, or the tariff in
    place when the “interconnection agreement” is executed or
    filed. Id. at 12. FERC decided in that case that the earlier tariff
    governs, despite what “appeared to be an unbroken
    Commission practice of holding that interconnection
    agreements filed after the designated effective date of an
    amended tariff are governed by the amended tariff.” Id. at 21.
    We held that the “one-off decision in this case to deviate” from
    settled agency practice was arbitrary. Id. FERC claimed a right
    to employ a case-by-case approach in making the timing
    20
    decision, but we dismissed the commission’s “paean to
    administrative flexibility” as unreasoned. Id. at 20. ITC argues
    FERC made the same mistake here, claiming a right to assess
    Transco independence case-by-case but failing to support its
    decision to do so with adequate reasoning or explanation.
    What ITC overlooks is that the regulatory background and
    established commission precedent here support a case-by-case
    approach in a way they did not in West Deptford. In West
    Deptford, the practice at issue was uniform, and FERC’s
    claimed adoption of a case-by-case approach arrived in the
    single decision in which it deviated from that uniform practice.
    We explained that a case-by-case approach as applied to that
    issue was in tension with the Federal Power Act’s prioritization
    of predictability and uniformity in tariff terms, and that FERC
    had entirely failed to “identify[] the relevant factors that would
    govern a case-by-case analysis.” Id. at 21. Here, by contrast,
    FERC expressly adopted a case-by-case approach to
    transmission incentives generally, and the Transco adder
    specifically, in Order No. 679. See 
    116 FERC ¶ 61,057
     at P43,
    P239. It explained that a “case-by-case approach ensures that
    the incentives granted will be tailored to particular
    circumstances.” 
    Id.
     at P43. With regard to the adder, FERC
    stressed that it would “evaluate the specific attributes of a
    particular proposal, including the level of independence,” in
    granting any adder. 
    Id.
     at P239. And FERC identified factors
    relevant to determining independence in the case of a Transco
    with active market affiliates—the factors applied in the case at
    hand—even as it declined to identify any particular
    methodology for weighing them. 
    Id.
     at P240. Unlike in West
    Deptford, then, FERC’s multi-factored assessment of ITC’s
    independence was not a departure from established precedent
    but a continuation of it.
    21
    At bottom, ITC’s claim is that FERC’s case-by-case
    determinations cannot be reconciled with one another on their
    facts, and that FERC failed to acknowledge or justify those
    inconsistencies. ITC argues that, whatever the ultimate finding
    as to the Order No. 679 criteria in NextEra and GridLiance, the
    only facts FERC actually considered in making those findings
    were the location and nature of the affiliated holdings. And in
    those analyses, the only market affiliates that FERC concluded
    could affect independence were those operating in the same
    regional markets as the Transcos at issue; affiliates or holdings
    outside those markets were found to have no effect on a
    Transco’s independence. ITC argues that if FERC had limited
    itself to those same geographical considerations in this case, it
    would have found ITC to be independent even after the merger,
    as neither GIC nor Fortis has subsidiaries operating in the
    Midcontinent Region. Additionally, ITC insists that, even if
    the Order No. 679 criteria FERC assessed were determinative,
    ITC has “at least as much independence from a corporate-
    structure perspective” as did the Transcos at issue in NextEra
    and GridLiance. Pet’rs Br. 33-34. Like ITC, those Transcos
    were reliant on parent companies for financial support, and,
    unlike ITC, neither was governed by its own board of majority-
    independent directors, but each was subject to the direction of
    its parent company’s board.
    The complainants below, now intervenors on appeal, have
    offered a possible rejoinder to ITC’s claim that the cases cannot
    be reconciled under a geographical analysis. They note that,
    while the market affiliates in this case are outside the
    Midcontinent Region, they are located in bordering areas close
    enough to be affected by ITC’s decisions. Whatever the merit
    of that argument, ITC’s first claim fails for a simpler reason:
    because, as discussed, FERC has never used a “geographically
    focused methodology” to determine independence, it was
    22
    under no obligation to reconcile the cases under the terms of
    such a test.
    ITC’s second claim—that FERC failed to analyze ITC’s
    structural independence relative to NextEra and GridLiance—
    is more clearly on point. As context for assessing that claim, it
    is worth considering the distinct procedural postures in which
    the cases arrived before FERC. Both NextEra and GridLiance
    involved proceedings under Section 205 of the Federal Power
    Act. See 16 U.S.C. § 824d. “Section 205 enables a utility to
    propose changes in its own rates.” Emera Me. v. FERC, 
    854 F.3d 9
    , 24 (D.C. Cir. 2017). Ratepayers can then challenge
    filed rates before they go into effect. See 16 U.S.C. § 824d(d)-
    (e). When a utility seeks to increase its rate, it bears the burden
    of demonstrating that the increase is just and reasonable. Id.
    § 824d(e).      Under FERC’s 2006 rule implementing
    transmission incentives, a utility’s request for incentive-based
    rate treatments must be made in a section 205 filing. 
    18 C.F.R. § 35.35
    (d).
    This case, on the other hand, arose in response to a
    complaint filed pursuant to Section 206 of the Federal Power
    Act. See 16 U.S.C. § 824e. “Section 206 empowers FERC to
    modify existing rates upon complaint or on FERC’s own
    initiative.” Emera Me., 854 F.3d at 24. Its procedures “are
    ‘entirely different’ and ‘stricter’ than those of section 205.” Id.
    (quoting City of Anaheim v. FERC, 
    558 F.3d 521
    , 525 (D.C.
    Cir. 2009)). Unlike in a Section 205 proceeding, the proponent
    of a rate change under Section 206 “bears ‘the burden of
    proving that the existing rate is unlawful.’” 
    Id.
     (quoting Ala.
    Power Co. v. FERC, 
    993 F.2d 1557
    , 1571 (D.C. Cir. 1993)).
    Against this procedural backdrop, the reason for FERC’s
    assertedly inconsistent analyses comes into sharper relief.
    Unlike in the case at hand, which arose entirely in response to
    23
    a Section 206 complaint that ITC was no longer independent,
    the issue of independence was not central in NextEra or
    GridLiance. The utilities in those cases requested several
    incentives in their Section 205 filings, only one of which was
    the Transco adder. NextEra, 
    162 FERC ¶ 61,196
     at P1;
    GridLiance, 
    164 FERC ¶ 61,049
     at P1. In both cases, several
    parties intervened to challenge elements of the Transcos’
    requests, but in neither did a party challenge the standard for
    assessing a Transco’s independence.
    In GridLiance, the only challenge raised to granting a
    Transco adder was based on the adder’s interaction with the
    overall return on equity and other incentives at issue. 
    164 FERC ¶ 61,049
     at PP33-36. No party even questioned the
    Transco’s decisional independence.
    In NextEra, the closest that any party got to an
    independence-centered challenge was the claim by an
    intervenor representing ratepayers that the Transco should not
    be treated as a standalone entity because it was supported by
    the financial strength of a parent company. See Notice of
    Intervention and Protest of the N.Y. State Public Service
    Comm’n at 6-7, NextEra, 
    162 FERC ¶ 61,196
    . That intervenor
    argued that the proposed base return on equity was sufficient
    to compensate investors for the project’s risks, rendering other
    incentives redundant. At no point did any party challenge or
    even discuss the criteria by which FERC assesses
    independence, and FERC’s order reflects as much. The
    Commission merely noted that “a Transco adder under Order
    No. 679 is not based on the specific risks of an applicant’s
    project, but based upon whether the applicant qualifies under
    the independence standard for a Transco and ‘continues to
    provide the benefits which we are trying to incentiv[ize].’” 
    162 FERC ¶ 61,196
     at P52 (quoting Order No. 679, 
    116 FERC ¶ 61,057
     at P226).
    24
    Here, by contrast, ratepayers came forward with evidence
    central to their claim that ITC’s independence had been
    reduced by the merger. FERC weighed that evidence against
    the Order No. 679 criteria and found that ITC’s independence
    had been reduced but not eliminated. In its request for
    rehearing ITC argued that FERC “offer[ed] no basis for”
    treating ITC differently from the Transcos in NextEra and
    GridLiance, but its only support for that assertion concerned
    the location of market affiliates, Request for Rehearing at 10-
    11 (J.A. 296-97), which FERC’s initial order made clear was
    not decisive in this case. As to the Order No. 679 criteria, ITC
    explained in its request for rehearing why it thought that FERC
    had gotten the analysis wrong, but it did not compare its
    decisional independence to that of the Transcos in those earlier
    cases. It asserted it was more independent than the NextEra
    Transco, but ITC did not even support that conclusory claim
    with any comparison of the factors that it contends demonstrate
    its greater independence, as it has sought to do here. For
    instance, ITC asserted its board was majority-independent
    without discussing how that compared to the board
    composition of the other Transcos; it does that for the first time
    in its petition to this court.
    None of this is to suggest ITC bore a burden of
    demonstrating it was more independent that the Transcos at
    issue in NextEra and GridLiance. It is simply to underscore as
    we consider how its precedents fit together that FERC was not
    confronted with any “significant showing that analogous
    cases” under Order No. 679 had “been decided differently.”
    LeMoyne-Owen Coll. v. NLRB, 
    357 F.3d 55
    , 61 (D.C. Cir.
    2004). Based on the evidence before FERC on rehearing and
    the case-by-case analysis Order No. 679 requires, it was
    reasonable for FERC to stand by its initial finding
    notwithstanding ITC’s standalone assertion of greater
    independence. FERC concluded that, while it “determined that
    25
    the integrity of [the NextEra Transco’s] investment planning,
    capital formation, and investment processes were unaffected by
    its affiliate relationships,” the “evidence in this record
    specifically demonstrate[d] that [ITC’s] affiliate relationships
    reduced the independence of its investment planning, capital
    formation, investment processes, and business structure.”
    Rehearing Order, 
    168 FERC ¶ 61,035
     at P20.
    FERC surely could have more extensively investigated
    investment planning, business structure, and capital formation
    in NextEra and GridLiance. It acknowledged as much in a
    recent decision raising the same issue as the one presented here.
    See Kansas Corp. Comm’n v. ITC Great Plains, LLC, 
    173 FERC ¶ 61,160
     at P8 (2020). FERC’s failure to address the
    Order No. 679 criteria more clearly in earlier cases, however,
    did not prevent it from considering all relevant evidence
    brought to its attention in this case.
    It is FERC’s duty under Section 206 to assess a
    complaint’s allegations that a utility’s existing rate is unjust or
    unreasonable. If FERC finds such allegations to be supported,
    it is then required to “determine the just and reasonable rate . . .
    [and] fix the same by order.” 16 U.S.C. § 824e. Here, FERC
    determined that ITC’s adders—then set at a level reserved for
    fully independent Transcos—were no longer appropriate. That
    finding triggered section 206’s requirement that it set a new just
    and reasonable rate. In view of the deference that we owe
    FERC in rate-related matters, we cannot conclude that this
    finding was undermined by other cases in which it faced
    different claims in procedurally distinct proceedings and
    reached different results based on distinct records.
    B. Section 206 Finding
    ITC also argues that FERC exceeded its statutory authority
    in the manner that it reduced the adders. Section 206 requires
    26
    “FERC to show that an existing rate is unlawful before ordering
    a new rate.” Emera Me., 854 F.3d at 24. ITC argues that FERC
    violated that mandate by failing to find the existing adders to
    be unjust or unreasonable before reducing them by half. See
    id. at 21.
    ITC’s claim fails, however, as FERC’s analysis clearly
    tracked “the two-step procedure mandated by section 206.” Id.
    at 22. In response to a complaint that expressly alleged the
    Transco adders had “been rendered unjust and unreasonable”
    as a result of the merger, FERC reassessed ITC’s
    independence. Complaint Order, 
    165 FERC ¶ 61,021
     at P1.
    Finding that the merger had reduced ITC’s independence,
    FERC reasonably concluded that the existing 50 basis point
    adder—a level reserved for “fully independent” Transcos—
    was no longer appropriate. Complaint Order, 
    165 FERC ¶ 61,021
     at P73; see also Rehearing Order, 
    168 FERC ¶ 61,035
    (Glick, Comm’r, dissenting in part) (concurring in the holding
    that “the Commission did not err in concluding that the then-
    existing ROE adder was unjust and unreasonable”). Only then
    did it proceed to set a new rate. Because the merger had
    reduced “but not eliminated” ITC’s independence, FERC
    concluded that a 25 basis point adder “appropriately
    encourages the Transco business model in these circumstances
    and promotes corresponding consumer benefits.” 
    Id.
    ITC’s challenge to that conclusion seems to rest primarily
    on FERC’s failure to use the words “unjust and unreasonable”
    at the first step. But because FERC granted a complaint that
    itself explicitly alleged the existing adders were unjust and
    unreasonable and its analysis tracked the two-step procedure of
    Section 206, its failure to “use the magic words . . . did not
    reflect a fatal flaw in its decision.” TransCanada Power Mktg.

    504 F.2d 203
    , 213 n.19 (D.C. Cir. 1974).
    This case is not like Emera Maine, our precedent on which
    ITC relies in claiming that FERC’s unjust-and-unreasonable
    finding must be expressed in those exact terms. See 854 F.3d
    at 24. In Emera Maine, FERC began by applying a
    methodology that identified a new just and reasonable rate.
    Based only on the fact that the newly identified rate was
    numerically lower than the existing rate, FERC concluded the
    existing rate was unjust and unreasonable, despite the fact that
    the existing rate also remained within a broader zone of
    reasonableness. Id. at 26. FERC in Emera Maine thus “never
    actually explained how the existing [rate] was unjust and
    unreasonable.” Id. It instead skipped to Section 206’s second
    step and reasoned backward from there, claiming that its
    analysis “generating a new just and reasonable [rate]
    necessarily proved that Transmission Owners’ existing [rate]
    was unjust and unreasonable.” Emera Me., 854 F.3d at 26; see
    also id. at 18-19 (contending that “both of the burdens of proof
    under . . . Section 206 can be satisfied using a single [return-
    on-equity] analysis” (quoting Coakley v. Bangor Hydro-Elec.
    Co., 
    150 FERC ¶ 61,165
     at P32 (2015))). The opinion under
    review is markedly different: All but a single paragraph of
    FERC’s analysis here concerned the first-step issue of whether
    the merger reduced ITC’s independence such that an adder
    level reserved for fully independent Transcos could no longer
    be considered just and reasonable as applied to ITC.
    ITC also claims that, “even if FERC had paid lip service
    to Section 206’s requirements,” its analysis could not support
    its finding that the existing adders were unjust or unreasonable.
    Pet’rs Br. 42. ITC argues that FERC’s analysis “rests on
    speculation rather than facts and evidence,” specifically
    criticizing FERC’s reliance on what ITC calls two
    28
    “unremarkable fact[s]”: (1) Fortis’s consolidated reporting of
    capital expenditures and (2) regular meetings of executives
    across Fortis’s regulated utilities. Id. 42-43. But ITC simply
    asserts without explanation that FERC was wrong in finding
    the consolidated planning “indicates some level of
    coordination and control.” Rehearing Order, 
    168 FERC ¶ 61,035
     at P19. ITC also does not challenge FERC’s finding
    that the ITC companies are dependent on Fortis for financing
    or that Fortis and GIC have members on ITC Holdings’ board
    who can “provide some oversight to ITC Holdings’
    executives.” Complaint Order, 
    165 FERC ¶ 61,021
     at PP70-
    71.     FERC’s analysis was thus not “based on sheer
    speculation,” as ITC contends. City of Centralia v. FERC, 
    213 F.3d 742
    , 749 (D.C. Cir. 2000). There was instead substantial
    evidence to support FERC’s finding that the merger had
    reduced ITC’s independence, thereby rendering the existing
    adders unjust and unreasonable.

    For the foregoing reasons, we deny the petition for review
    filed by International Transmission Company, ITC Midwest,
    LLC, and Michigan Electric Transmission Company, LLC.
    So ordered.
    SENTELLE, Senior Circuit Judge, dissenting: Federal agencies
    are creatures of statute. They have no power to act except as
    directed by Congress. See Michigan v. EPA, 
    268 F.3d 1075
    , 1081
    (D.C. Cir. 2001). In the Federal Power Act, Congress directed
    FERC to set “just and reasonable” rates for electric transmission.
    16 U.S.C. §§ 824d(a), 824e. Section 205 applies when a utility
    company proposes a new rate; the company must show that the
    proposal is just and reasonable. See § 824d(a). Section 206 applies
    when FERC alters an existing rate, either sua sponte or at a third
    party’s request. See § 824e. To alter an existing rate under § 206,
    FERC must first find that the existing rate is unjust or unreasonable.
    See § 824e(a); Fed. Power Comm’n v. Sierra Pac. Power, 
    350 U.S. 348
    , 353 (1956) (describing this finding as a “condition precedent”
    to FERC’s § 206 authority).
    Here, FERC altered ITC’s rate under § 206 without finding the
    existing rate unjust or unreasonable. Put differently, FERC acted
    outside its statutory authorization. The majority affirms FERC’s
    action by assuming that because FERC deemed the new rate more
    “appropriate,” it must have considered the old rate unjust or
    unreasonable. See ante at 26; accord Consumers Energy Co. v.
    Int’l Transmission Co., 
    165 FERC ¶ 61,021
     at P73, 
    2018 WL 5267539
     at *16 (2018). Yet under SEC v. Chenery Corp., we can
    only affirm for the reasons FERC offered, without assuming
    alternative conclusions FERC did not provide. See 
    318 U.S. 80
    , 87-
    88 (1943). So although I agree that FERC did not arbitrarily or
    capriciously depart from its precedent, I disagree with the decision
    to deny ITC’s petition for review. I would vacate and remand for
    FERC to consider whether ITC’s original rate was unjust or
    unreasonable.
    In my judgment, this case is governed by Emera Maine v.
    FERC, 
    854 F.3d 9
     (D.C. Cir. 2017). In that case, consumer-side
    stakeholders filed a complaint under § 206 of the Federal Power
    Act, alleging that a transmission company’s rates had become
    unjust and unreasonable. In response, FERC reduced the rates to a
    level it deemed more just and more reasonable without expressly
    2
    finding the prior rate unjust or unreasonable. When the
    transmission company appealed to this Court, FERC argued “that
    by setting a new just and reasonable [rate], it necessarily found that
    [the transmission company’s] existing [rate] was unjust and
    unreasonable.” 854 F.3d at 15. The Emera Maine court rejected
    FERC’s argument, concluding that “[w]ithout a showing that the
    existing rate is unlawful, FERC has no authority to impose a new
    rate.” Id. at 25. Today’s decision resurrects what Emera Maine laid
    to rest nearly four years ago.
    The majority attempts to distinguish Emera Maine because, in
    that case, FERC “never actually explained how the existing [rate]
    was unjust and unreasonable,” as Congress requires. Ante at 27
    (alteration in original) (quoting 854 F.3d at 26). Yet the same could
    be said about FERC’s decision here. FERC explains only why the
    new rate is more “appropriate.” Int'l Transmission Co., 
    165 FERC ¶ 61,021
     at P73. Explaining why the new rate is more
    appropriate does not explain whether the original rate was unjust or
    unreasonable.
    The majority’s distinction-without-a-difference gives short
    shrift to Emera Maine and to our other decisions holding that
    “section 206 mandates a two-step procedure that requires FERC to
    make an explicit finding that the existing rate is unlawful before
    setting a new rate.” 854 F.3d at 24; see also Am. Gas Ass’n v.
    FERC, 
    912 F.2d 1496
    , 1504 (D.C. Cir. 1990) (“[T]he directive to
    impose a just and reasonable rate . . . is triggered only by the
    Commission’s finding that the existing one is ‘unjust[ or]
    unreasonable . . . .’” (quoting § 824e(a))); City of Bethany v. FERC,
    
    727 F.2d 1131
    , 1143 (D.C. Cir. 1984) (“[U]nder section 206,
    FERC itself may establish the just and reasonable rate, provided
    that it first determines that a rate set by a public utility is unjust[ or]
    unreasonable . . . .”). By retreating from that well-reasoned and
    workable rule, we invite FERC to further erode congressional
    limits on its delegated power.
    3
    FERC dismisses those congressional limits as “magic words,”
    alluding to Hanna Diyab’s Ali Baba and the Forty Thieves.
    Respondent Br. 26, 36. Yet FERC would do well to remember that
    when Ali Baba’s brother forgot the magic words, he could not
    escape the thieves’ cave. Although “unjust” or “unreasonable” are
    congressional requirements rather than magic words, I would
    likewise refuse to allow FERC to escape a trap of its own making.
    I respectfully dissent.
