    Before: GRIFFITH and SRINIVASAN, Circuit Judges, and
    SENTELLE, Senior Circuit Judge.
    Opinion for the Court filed by Senior Circuit Judge
    SENTELLE.
    SENTELLE, Senior Circuit Judge: Petitioner FirstEnergy
    Service Company is a diversified energy company acting on
    behalf of its affiliates American Transmission Systems, Inc.
    (“ATSI”) and a collection of ATSI Utilities. Like many
    electric utility companies, FirstEnergy is a voluntary member
    of a Regional Transmission Organization (“RTO”). In June
    2011, FirstEnergy transferred from one RTO to another. In
    doing so, it incurred costs related to transmission projects
    both from the organization it left, MISO, and from the one it
    entered, PJM. FirstEnergy filed a complaint with the Federal
    Energy Regulatory Commission (“FERC” or “the
    Commission”), contending that the imposition of costs from
    both RTOs on ATSI was unjust and unreasonable. The
    Commission disagreed and dismissed the complaint.
    FirstEnergy now petitions this court for review of FERC’s
    orders. For the reasons set forth below, we conclude that the
    Commission did not commit reversible error in its
    determination and therefore affirm the orders under review.
    BACKGROUND
    Statutory and Regulatory Overview
    Two related but distinct sections of the Federal Power
    Act (“FPA”) govern FERC’s adjudication of just and
    reasonable rates: section 205, codified at 16 U.S.C. § 824(d),
    and section 206, codified at 16 U.S.C. § 824(e). Section 205
    3
    confers upon FERC the duty to ensure that wholesale energy
    rates and services are just and reasonable. 16 U.S.C.
    § 824d(a). No public utility under FERC’s jurisdiction may
    “make or grant any undue preference or advantage to any
    person or subject any person to any undue prejudice or
    disadvantage” in establishing rates. 
    Id. § 824d(b).
    Section
    205 requires regulated utilities to file with the Commission
    tariffs outlining their rates for FERC’s approval.         
    Id. § 824d(c).
        Section 206 empowers FERC to make a
    determination on existing rates and to modify them if they are
    found to be “unjust, unreasonable, unduly discriminatory or
    preferential.” 
    Id. § 824e(a).
    An investigation under section
    206 may arise upon complaint or on FERC’s own initiative.

    No. 1 v. FERC, 
    272 F.3d 607
    (D.C. Cir. 2001) (per curiam),
    the Commission created RTOs, which operate the
    transmission grid to provide access for all “at rates established
    in a single, unbundled, grid-wide tariff.” NRG Power Mktg.,
    LLC v. Me. Pub. Utils. Comm’n, 
    558 U.S. 165
    , 169 n.1
    (2010). Generally, these are voluntary associations of
    transmission facilities that administer energy markets and file
    tariffs for a group of utilities under section 205. Two such
    RTOs are the Midwest Independent System Operator, Inc.
    (“MISO”) and PJM Interconnection, L.L.C. (“PJM”).
    MISO and PJM
    This case involves FirstEnergy’s relationship to both
    MISO and PJM. For years, FirstEnergy’s operations were
    4
    split between the two RTOs, requiring FirstEnergy to operate
    under two sets of rules. In August of 2009, FirstEnergy filed
    a “Realignment Request” seeking FERC’s “approval to
    realign FirstEnergy’s operations within a single RTO: PJM.”
    Realignment Request at 2. The Realignment Request asserted
    that “[m]oving ATSI into the RTO with which it has stronger
    electrical ties should reduce congestion and increase
    efficiency across both RTOs.” 
    Id. at 3.
    In June 2011,
    FirstEnergy transferred from MISO to PJM. Rehearing Order
    ¶ 4.
    In administering their respective markets, RTOs socialize
    the cost of new transmission projects among RTO members.
    MISO and PJM allocate such transmission project costs
    differently. Generally, MISO allocates costs among members
    at the time specific projects are approved. See Pub. Serv.
    Comm’n of Wisconsin v. FERC, 
    545 F.3d 1058
    , 1060–61
    (D.C. Cir. 2008) (describing and approving MISO’s Tariff
    Attachment FF, titled “Transmission Expansion Planning
    Protocol”). “[A] Party that withdraws from [MISO] shall
    remain responsible for all financial obligations incurred
    pursuant to this Attachment FF while a Member of
    [MISO]. . . .” Realignment Request at 39 (citing MISO
    Tariff, Attach. FF § III.A.2.i).
    PJM, in contrast, reallocates transmission project costs on
    a yearly basis pursuant to Schedule 12 of its tariff. The tariff
    allocates these costs to each transmission owner based on its
    share of PJM’s total load, and recalculates the allocations on
    an annual basis. See Realignment Order ¶ 98.
    A key feature of PJM’s [regional transmission
    expansion] process, and of cost allocation based upon
    it, is to annually restudy and consider modifications to
    5
    the portfolio of projects in the plan as the needs of the
    region change. Unlike the one-time allocation of costs
    of lower voltage projects, providing for an annual
    reallocation of the costs of high voltage facilities pro
    rata based on load-ratio share will help ensure that,
    over time, the costs of these projects are allocated to
    those who are likely to benefit.
    PJM Interconnection, L.L.C., 138 FERC ¶ 61,230 P 62
    (2012), on reh’g, 142 FERC ¶ 61,216 (2013), vacated on
    other grounds, Ill. Commerce Comm’n v. FERC, 
    2014 WL 2873936
    (7th Cir. June 25, 2014). PJM does not allocate
    regional transmission costs to withdrawing transmission
    owners. See Duquesne Light Co., 122 FERC ¶ 61,039, reh’g
    denied, 124 FERC ¶ 61,219 P 164 (2008) (“[A] departing
    transmission owner leaving PJM would, pursuant to
    [Schedule 12], no longer be subject to these charges; it would
    not have a zonal annual peak load [with which to calculate its
    costs] as it would no longer be a zone in PJM.”).
    Due to these differing methodologies, a transmission
    owner that withdraws from MISO is still responsible for its
    share of transmission costs allocated prior to its withdrawal.
    Conversely, a utility that withdraws from PJM is no longer
    responsible for costs in ensuing yearly allocations; any costs
    going forward are redistributed among PJM members at that
    time, regardless of when the projects were approved. Because
    FirstEnergy withdrew from MISO and joined PJM, it is
    responsible for both its prior MISO costs and its share of the
    yearly reallocation for so-called legacy projects in PJM
    approved before it joined. Realignment Request at 35.
    6
    Proceedings Before the Commission
    In effecting its transfer from MISO to PJM, FirstEnergy
    submitted filings under both section 205 and section 206.
    Through these submissions, it sought to secure termination of
    ATSI’s participation in MISO and to garner approval of its
    integration into PJM.
    On August 17, 2009, FirstEnergy (on behalf of ATSI)
    submitted its Realignment Request under FPA section 205.
    FirstEnergy requested approval of its withdrawal from MISO
    and permission to transfer into PJM under the terms set forth
    in an ATSI-PJM Integration Agreement.            Realignment
    Request at 18, 27–35 & Ex. 1. ATSI reported that, under the
    Integration Agreement, the ATSI Utilities would “continue to
    pay for qualifying [MISO] regional facilities planned and
    approved before June 1, 2011,” but would “not pay for PJM
    legacy . . . projects that were approved by the PJM Board
    prior to ATSI’s entry into PJM.” 
    Id. at 35.
    The ATSI Utilities
    would, “of course, pay for qualifying [PJM] projects planned
    and approved by the PJM Board after their June 1, 2011 date
    when their load is integrated into PJM.” 
    Id. PJM itself
    “support[ed] FirstEnergy’s implementation plan for
    integrating ATSI into the PJM region” and “believe[d] that
    FirstEnergy has met the applicable requirements of exiting
    [MISO] and joining PJM.” PJM Comments on Realignment
    at 2. PJM went on to note that nothing in the language of
    Schedule 12 contemplates cost allocation when a new
    member joins PJM. 
    Id. at 11–12
    (Schedule 12 was “not
    designed with the scenario in mind of an altogether new
    Transmission Zone joining PJM.”).
    Additionally, FirstEnergy sought specific findings from
    the Commission as to two matters: (1) a waiver of certain
    7
    PJM auction procedures with which it would be unable to
    comply due to timing, Realignment Request at 11–12; see
    also Realignment Order ¶ 59; and (2) an exemption from PJM
    reallocation costs for projects approved prior to ATSI’s
    integration (“legacy projects”), Realignment Request at 35.
    On October 19, 2009, FirstEnergy submitted a section
    206 filing (“Complaint”) to the Commission.           In the
    Complaint, ATSI through FirstEnergy alleged that if FERC
    denied its legacy projects exemption request, Schedule 12 of
    the PJM tariff would be unjust and unreasonable as applied to
    ATSI. Complaint at 2–3 (noting that the parallel 206 filing
    was made in response to arguments by “several parties in [the
    Realignment Proceeding] . . . that the ATSI Utilities had no
    right to seek this relief absent the filing of a section 206
    complaint”).
    FERC issued two orders responsive to petitioner’s filings.
    Order Addressing RTO Realignment Request and Complaint,
    129 FERC ¶ 61,249 (December 17, 2009) (“Realignment
    Order”); Order Addressing Remaining Requests for
    Rehearing and Clarification, 140 FERC ¶ 61,226 (September
    20, 2012) (“Rehearing Order”). In the Realignment Order,
    FERC held that ATSI satisfied the requirements to withdraw
    from MISO, Realignment Order ¶ 48, and accepted the
    integration plan into PJM, 
    id. ¶ 78.
    The Commission also
    granted the auction waiver ATSI sought. 
    Id. However, FERC
    denied the legacy projects exemption.
    
    Id. ¶ 111.
        FERC applied the section 206 standard to
    FirstEnergy’s requested exemption, explaining that it “cannot
    find . . . that allocating a portion of [those] costs to new
    entrants is unjust and unreasonable, or unduly discriminatory
    or preferential.” 
    Id. ¶ 7.
    The Commission further found that
    8
    FirstEnergy was responsible for the costs attributable to its
    decision to transfer between RTOs. “While we have held that
    companies are free to join and exit RTOs, we have applied the
    existing tariffs for each RTO in determining the costs to be
    allocated to the transmission owners seeking to exit and/or
    enter.” 
    Id. ¶ 113.
    It is up to FirstEnergy to “determine
    whether such a move is cost-justified.” 
    Id. FirstEnergy timely
    filed two requests for rehearing on
    January 15, 2010 and January 19, 2010. FirstEnergy raised
    two principal arguments: First, it contended that FERC had
    unlawfully and irrationally dismissed its complaint under
    section 206 on the ground that the challenged tariff provision
    had previously been found reasonable when initially filed
    under FPA section 205. Second, it contended that FERC’s
    ruling violated cost causation principles and resulted in
    reallocating sunk costs. Rehearing Request at 3–4, 6, 16–18.
    Thirty-two months later, on September 20, 2012, FERC
    issued its order denying rehearing on the legacy projects
    issue. Rehearing Order ¶ 21. “Specifically, we cannot find
    on this record that PJM’s tariff is unjust and unreasonable in
    allocating to a new member, such as ATSI, a share of the
    costs of regional transmission expansion projects . . . that
    were planned prior to the new member’s integration into
    PJM.” 
    Id. The Commission
    also rejected FirstEnergy’s
    arguments on cost causation and sunk costs, noting for the
    first time that “[c]ost causation also includes the allocation of
    ‘costs to serve’ that party including those facilities that benefit
    the party.” 
    Id. ¶ 26.
    Finally, FERC found that the costs
    FirstEnergy incurred in its transfer were not duplicative: the
    costs associated with MISO are a contract exit fee not based
    on a finding of benefits, while PJM’s costs are related to the
    benefit flowing to FirstEnergy. 
    Id. ¶ 34.
    Fundamentally, the
    9
    Commission was “not persuaded that . . . PJM’s tariff is
    unjust and unreasonable. RTO participation is voluntary, as
    the Commission has made clear on numerous occasions.
    ATSI, in considering the merits of its membership in PJM,
    elected to proceed and, thus, cannot now claim that PJM’s
    [transmission project] cost allocation methodology created a
    barrier to entry.” 
    Id. ¶ 31.
                         Petition for Review
    Petitioner seeks review of both orders before this Court.
    FirstEnergy contends generally that FERC erred in its
    treatment of the complaint and arbitrarily and capriciously
    required ATSI to pay for PJM’s legacy transmission costs.
    According to FirstEnergy, such a requirement is “contrary to
    cost causation principles and FERC’s well-established policy
    against reallocating sunk costs.” Pet. Br. at 3. Moreover,
    petitioner argues, FERC’s blanket adherence to PJM’s tariff is
    an arbitrary and capricious failure to meaningfully consider
    the merits of its section 206 filing.
    We disagree, and deny FirstEnergy’s petition for review.
    For the reasons discussed below, we hold that the
    Commission correctly determined that FirstEnergy had not
    carried its burden under FPA section 206 of demonstrating
    that Schedule 12 of PJM’s tariff was unjust and unreasonable
    as applied to ATSI.
    STANDARD OF REVIEW
    We review final orders of the Commission under the
    arbitrary and capricious standard of the Administrative
    Procedure Act, 5 U.S.C. § 706(2)(A). An agency action will
    be upheld if the agency “articulate[d] a satisfactory
    10
    explanation for its action including a ‘rational connection
    between the facts found and the choice made.’ ” Motor
    Vehicle Mfrs. Ass’n of United States, Inc. v. State Farm Mut.
    Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983) (quoting Burlington
    Truck Lines, Inc. v. United States, 
    371 U.S. 156
    , 168 (1962)).
    The Commission’s factual findings will be upheld if
    supported by substantial evidence. 16 U.S.C. § 825l(b).
    DISCUSSION
    We begin by addressing petitioner’s concern that “the
    orders on review effectively deny a utility’s right to file a
    complaint under FPA section 206 to request modification of
    an RTO tariff when joining an RTO.” Pet. Br. at 22. The
    Commission did in this case dismiss petitioner’s complaint.
    Realignment Order ¶ 111. Petitioner contends that the
    Commission’s dismissal was a wholesale discarding of
    FirstEnergy’s filing which operates as a violation of rights
    guaranteed to petitioner under Atlantic City Elec. Co. v.
    FERC, 
    295 F.3d 1
    (D.C. Cir. 2002). Pet. Br. at 22.
    Specifically, FERC’s orders purportedly run afoul of Atlantic
    City, where we held that FERC may not lawfully compel a
    public utility that joins an RTO to surrender its statutory right
    to exit the organization under section 205. 
    See 295 F.3d at 9
    –
    10. We disagree. FERC did not preclude petitioner from
    asserting its Complaint, or exercising any statutory right. It
    did not indulge in the sort of wholesale dismissal of
    petitioner’s arguments that petitioner posits. Instead, FERC
    addressed petitioner’s Complaint on the merits. Rehearing
    Order ¶¶ 21, 29, 32; see Realignment Order ¶ 112 (“ATSI’s
    voluntary choice to move from one RTO to another does not
    cause either of [the transmission cost allocation]
    methodologies to no longer be just and reasonable or not
    unduly discriminatory simply because each produces a
    11
    different result.”). The linguistic choice by FERC to state
    that it was “dismiss[ing]” FirstEnergy’s Complaint rather than
    “denying” it does not convert that which is substantively
    sufficient into redressible error. Realignment Order ¶ 111.
    “The deeper problem with FERC’s holding,” petitioner
    tells us, “is that it is unlawful and irrational to dismiss any
    complaint under FPA section 206 on the ground that the
    challenged tariff provision was previously found reasonable
    when initially filed under FPA section 205.” Pet. Br. at 24.
    Perhaps that is true as an abstract statement of law. However,
    we cannot agree that FERC’s review was so hollow. The
    treatment given the provision under review was meaningful,
    as discussed below, and not the recitation petitioner describes.
    “Just and Reasonable” Determination
    “Generally speaking, section 205 covers rate filings by
    jurisdictional public utilities [and] invokes just and reasonable
    standards for filed rates . . . .” Ala. Power Co. v. FERC, 
    993 F.2d 1557
    , 1571 (D.C. Cir. 1993). “Section 206 empowers
    the Commission, on its own motion or upon complaint, to
    investigate rates and to determine the lawfulness of such
    rates.” 
    Id. The statutory
    “just and reasonable” standard is
    the same under section 205 and section 206. See, e.g., Bos.
    Edison Co. v. FERC, 
    233 F.3d 60
    , 64 (1st Cir. 2000) (“[T]he
    utility sets the rates in the first instance, subject to a basic
    statutory obligation that rates be just and reasonable and not
    unduly discriminatory or preferential. FERC . . . can
    investigate a newly filed rate (section 205), or an existing rate
    (section 206), and, if the rate is inconsistent with the statutory
    standard, order a change in the rate to make it conform to that
    standard.” (internal citations omitted)); Kan. Gas & Elec. Co.
    v. FERC, 
    758 F.2d 713
    , 716 (D.C. Cir. 1985) (“FERC
    12
    evaluated the proposed rates under Sections 205 and 206 of
    the Federal Power Act, both of which require the Commission
    to determine that the rates are just and reasonable.” (internal
    quotation marks and citation omitted)).
    “Because [petitioner] is challenging . . . existing rates, its
    claim must be brought pursuant to § 206, rather than § 205, of
    the FPA.” Sithe/Independence Power Partners, L.P. v.
    FERC, 
    165 F.3d 944
    , 948 (D.C. Cir. 1999). Section 206(a)
    provides that “[w]henever the Commission, after a hearing
    held upon its own motion or upon complaint, shall find that
    any rate . . . is unjust, unreasonable, unduly discriminatory or
    preferential, the Commission shall determine the just and
    reasonable rate . . . .” 16 U.S.C. § 824e(a). Under section
    206, “the burden of proof to show that any rate, charge,
    classification, rule, regulation, practice, or contract is unjust,
    unreasonable, unduly discriminatory, or preferential shall be
    upon . . . the complainant.” 
    Id. § 824e(b).
    Thus, we consider this complaint on a typical section 206
    standard.       Here, FirstEnergy bears the burden of
    demonstrating that, as applied to ATSI, Schedule 12 of PJM’s
    tariff is unjust and unreasonable. FERC argues on brief that a
    section 206 filing carries with it a dual burden: petitioner
    “first must show that the existing rate or practice is unjust,
    unreasonable, unduly discriminatory or preferential, and then
    must demonstrate that its own proposal is a just and
    reasonable replacement.”       Br. for FERC at 4 (citing
    Blumenthal v. FERC, 
    552 F.3d 875
    , 881 (D.C. Cir. 2009)).
    To begin our analysis, we note that FERC does hold
    petitioner—and indeed any filer under section 206 save the
    Commission itself—to too high a standard. The “just and
    reasonable” lodestar is no loftier under section 206 than under
    13
    section 205, and it is only FERC who is required to shoulder
    the “dual burden” when it institutes a section 206 proceeding.
    See, e.g., Ala. Power 
    Co., 993 F.2d at 1571
    (“While the
    proponent of a rate change under § 206, here FERC, has the
    burden of proving that the existing rate is unlawful . . . the
    party filing a rate adjustment with the Commission under
    § 205 bears the burden of proving the adjustment is lawful.”
    (internal citations omitted)). As petitioner correctly notes,
    we rejected the above “dual burden” reasoning in Blumenthal
    as “unnecessary to our holding and inaccurate insofar as it
    implied that a challenge to rates must propose alternative rates
    that are just and reasonable.” Md. Pub. Serv. Comm’n v.
    FERC, 
    632 F.3d 1283
    , 1285 n.1 (D.C. Cir. 2011). It is “the
    Commission’s job—not the petitioner’s—to find a just and
    reasonable rate.” 
    Id. However, clarification
    of this standard here is cold
    comfort to petitioner. Regardless of whether it is charged
    with completing step two, proposing new just and reasonable
    rates, it still must complete step one, demonstrating that
    PJM’s existing rates are unjust and unreasonable. Our
    question then is whether petitioner met its burden as to the
    existing rates, and we agree with the Commission that it did
    not. We hold that FERC did not err in rejecting each of
    petitioner’s arguments as failing to demonstrate that PJM’s
    Schedule 12 was unjust and unreasonable as applied to ATSI.
    Cost Causation and Sunk Cost Allocation
    FirstEnergy first argues that the Commission’s failure to
    meaningfully engage on the cost concerns attendant PJM’s
    tariff renders the orders before us arbitrary and capricious.
    We cannot agree with this characterization of the orders on
    review. FERC considered each of the arguments raised by
    14
    petitioner and appropriately concluded that they did not
    render application of Schedule 12 unjust and unreasonable.
    That the Commission did not agree with petitioner’s
    assessment of the effects Schedule 12 would have on
    FirstEnergy does not render its determination arbitrary and
    capricious.
    FirstEnergy alleged that it cannot be just and reasonable
    to require it to pay both MISO’s system-wide costs as an exit
    fee and PJM’s system-wide costs as a condition of its entry to
    PJM. Complaint at 8. However, the Commission reasonably
    found that the payment structures for MISO and PJM are
    wholly distinct from each other and undertaken for separate
    purposes. Rehearing Order ¶¶ 33–34. As a result, “ATSI’s
    voluntary choice to move from one RTO to another does not
    render [either methodology] unjust or unreasonable . . .
    simply because each methodology produces a different
    result.” 
    Id. ¶ 33.
    We are satisfied that this is a reasonable
    basis on which to reject the section 206 complaint.
    The Commission went on to point out that “ATSI and the
    PJM transmission owners are free to negotiate the terms of
    ATSI’s entrance into PJM” and that PJM would “have both a
    will and an incentive to facilitate ATSI’s realignment on a
    mutually beneficial basis.” Realignment Order ¶ 114. This
    strategy may have been especially effective given that PJM
    agrees that Schedule 12 did not contemplate integration of
    new transmission owners or allocating legacy costs to them.
    
    Id. ¶ 113
    n.75; PJM Comments on Realignment Request at
    11–12. Petitioner incorrectly characterizes this finding as
    “[breaking] new ground by holding that a complaint could be
    rejected because FERC prefers that the parties file a
    negotiated proposal under FPA section 205.” Pet. Br. at 30.
    One does not follow from the other—FERC rejected the
    15
    complaint because it found that the rates as applied were not
    unjust and unreasonable; that it suggested an alternative via
    negotiation does not change this determination. In any event,
    petitioner did have the opportunity to negotiate with PJM in
    the eighteen months between the Realignment Order and
    FirstEnergy’s integration into the RTO and could have at that
    point submitted a section 205 filing with new terms alongside
    PJM. Such an approach would have allowed FirstEnergy to
    avoid its burden as to the existing tariff. See 16 U.S.C.
    § 824d. Instead, it made the choice to join PJM without such
    a negotiated agreement, and is unable to demonstrate the
    requisite “unjust and unreasonable” showing that it must
    establish under section 206.
    In addition to its argument on duplicative costs, petitioner
    also contends that Schedule 12 presents inescapable fallacies
    concerning cost causation and reallocation of sunk costs.
    However, in principle, a “beneficiary pays” approach is a just
    and reasonable basis for allocating the costs of regional
    transmission projects, even if it leads to reallocating sunk
    costs. As the Commission found, cost causation “includes the
    allocation of ‘costs to serve’ that party including those
    facilities that benefit the party.” Rehearing Order ¶ 26.
    “Even if a new member was not using the system when a
    particular project was planned or authorized, the new member
    may nevertheless use and benefit from the new facility in the
    future.” 
    Id. PJM’s comments
    that Schedule 12 was not
    implemented with new RTO members in mind are immaterial.
    Because FirstEnergy will use and benefit from the new
    facilities, 
    id. ¶ 26
    & n.27, we defer to FERC’s conclusion that
    the costs FirstEnergy will incur are not unjust and
    unreasonable under a “costs to serve” approach.
    16
    FirstEnergy goes on to complain that the transmission
    costs here are also “sunk” in that investment decisions about
    these facilities were made before petitioner sought to join
    PJM. Pet. Br. at 51–54. Petitioner notes that FERC has in
    other cases shied away from redistributing costs that have
    already been incurred, or are sunk. See PJM Interconnection,
    L.L.C., Opinion No. 494, 119 FERC ¶ 61,063 at P 53 (2007),
    reh’g denied, Opinion No. 494-A, 122 FERC ¶ 61,082
    (2008), reh’g denied, 124 FERC ¶ 61,033 (2008), reh’g and
    clarification denied, 127 FERC ¶ 61,092 (2009), aff’d in
    relevant part, Ill. Commerce Comm’n, 
    576 F.3d 470
    , 474 (7th
    Cir. 2009). However, the Commission’s prior decisions
    concerning sunk costs are inapplicable where they involved
    facilities “built solely for the benefit of the individual
    transmission owner’s systems.” Rehearing Order ¶ 30. By
    contrast, PJM’s “project costs that will be allocated to the
    ATSI zone were developed as part of PJM’s regional planning
    process and are designed to benefit the entire PJM footprint
    over the entirety of their useful life.” 
    Id. Further, the
    transmission planning process in PJM accommodates updates:
    it will take into account the addition of FirstEnergy to the
    regional grid, which can result in changes to planned projects.
    
    Id. ¶ 29.
    As a result, we agree with the Commission that the
    rates at issue here are not unjust and unreasonable as a
    reallocation of sunk costs.
    It is worth noting that FERC did not address these issues
    until rehearing.     Rehearing Order ¶ 26. Further, we are
    sympathetic to FirstEnergy in its reliance on the Seventh
    Circuit’s rejection of the same Schedule 12 in Illinois
    Commerce Commission v. FERC, 
    576 F.3d 470
    , 476 (7th Cir.
    2009). Petitioner explains its rationale as: “[i]n [Illinois
    Commerce Commission], the Seventh Circuit found that
    FERC failed to support its cost causation theory with respect
    17
    to existing members of PJM; it follows a fortiori that FERC
    cannot rely on the same cost causation theory to socialize
    legacy project costs to new members of PJM who had no say
    in the decision to build them.” Pet. Br. at 48. However, the
    Seventh Circuit rejected Schedule 12 on a finding that FERC
    had not demonstrated that the benefits from transmission
    projects were “at least roughly commensurate with . . .
    utilities’ share of total electricity sales.” Ill. Commerce
    
    Comm’n, 576 F.3d at 477
    . Although FirstEnergy might have
    argued before us that the costs and benefits of PJM’s regional
    projects are not commensurate for ATSI, it did not do so and
    thus we do not reach that issue. 1
    “[A]ll approved rates [must] reflect to some degree the
    costs actually caused by the customer who must pay them.”
    
    Id. at 476
    (alteration in original) (internal citation and
    quotation marks omitted). FERC found that petitioner’s
    customers would use and benefit from the new facilities,
    Rehearing Order ¶¶ 26, 34, and noted that facilities may
    provide benefits over their lifetime, including benefits to
    petitioner, 
    id. ¶ 30.
    We defer to the Commission’s reasoned
    finding.
    Waiver or Modification of Tariff Provisions
    Finally, FirstEnergy broadly argues that FERC’s orders
    regarding the section 206 complaint are based almost entirely
    on the tariffs already in place in both RTOs. It reasoned that
    1
    The Seventh Circuit recently had occasion to reconsider Schedule
    12 in Illinois Commerce Comm’n v. FERC, 
    2014 WL 2873936
    , __
    F.3d __ (7th Cir. June 25, 2014). That decision reinforced the
    earlier determination in Illinois Commerce Commission that FERC
    failed to demonstrate commensurate benefits, and thus does not
    influence our conclusion here.
    18
    it had already found those rates just and reasonable and thus
    FirstEnergy can make no argument to the contrary. However,
    FERC is required to evaluate a 206 complaint as to existing
    rates specifically because they might have become unjust and
    unreasonable by intervening shifts in circumstances—e.g.,
    ATSI’s leaving MISO and joining PJM. Pet. Br. at 25 (citing
    La. Pub. Serv. Comm’n v. FERC, 
    482 F.3d 510
    , 519–20 (D.C.
    Cir. 2007)). It is not enough, FirstEnergy states, to repeat that
    “the plain language of the tariff governs,” and doing no more
    than that is an arbitrary and capricious failure to meaningfully
    respond to petitioner’s statutory challenge. Pet. Br. at 23–24.
    But FERC did not simply repeat that the plain language
    of the tariff governs. The Commission reasoned that “[e]ach
    of the PJM and [MISO] cost allocation methodologies has
    been accepted by the Commission as just and reasonable,”
    and that “ATSI’s voluntary choice to move from one RTO to
    another does not cause either of [those] methodologies to no
    longer be just and reasonable.” Realignment Order ¶ 112.
    This statement is the upshot of FirstEnergy’s failure to carry
    its burden, and FERC lawfully declined to waive the legacy
    projects costs or modify the tariff so FirstEnergy could avoid
    them.
    Petitioner argues that the legacy projects costs it seeks to
    avoid are no different than the auction procedures FERC
    waived; both were findings petitioner requested of FERC in
    order to facilitate the transition into PJM, yet the Commission
    treated the requests differently. However, the Commission
    articulated a reasoned distinction between the auction waiver
    and the legacy projects exemption—that the former is to
    provide an alternative means of tariff compliance, while the
    latter is wholesale removal of a tariff requirement. Rehearing
    Order ¶ 40. FirstEnergy did not show that it could not comply
    19
    with the tariff requirement regarding legacy projects costs,
    nor did its requested exemption from those costs seek an
    alternative means of compliance. Rather, as the Commission
    found, the requested exemption sought to “remove a tariff
    requirement entirely.” 
    Id. For that
    reason, FERC reasonably
    distinguished between FirstEnergy’s requested findings here
    and found “no inconsistency in accepting the [auction
    procedure] waiver, while rejecting the request for an
    exemption from [legacy projects costs].” 
    Id. Nor do
    we.
    Finally, says petitioner, illustrative of the Commission’s
    caprice is its theory that the tariff here could not be modified
    while other tariffs could. Pet. Br. at 41–42 (arguing that the
    Commission modified the tariff in the MidAmerican
    proceedings); 
    id. at 42–44
    (same regarding Entergy).
    However, the Commission reasonably found that
    circumstances required for modification of a tariff were not
    present in ATSI’s case. Most importantly, as discussed
    above, the Commission did not find the existing tariff to be
    unjust and unreasonable as applied to ATSI, as required under
    the FPA. This was not a case where an RTO itself submitted
    a 205 filing to change its own tariff, obviating the need for an
    “unjust and unreasonable” showing. Finally, the parties did
    not negotiate a settlement. Absent such circumstances, there
    was no authority for FERC to modify the tariff and the plain
    language of the tariff does indeed govern. See Realignment
    Order ¶ 113 n.75.
    CONCLUSION
    Because FirstEnergy failed to carry its burden under
    section 206 that Schedule 12 of PJM’s tariff was unjust and
    unreasonable as applied to ATSI, we deny the petition for
    review.
