    SENTELLE.
    SENTELLE, Senior Circuit Judge: In September 2010, the
    Federal Energy Regulatory Commission (“FERC”) approved
    a settlement between PJM Interconnection, L.L.C. (“PJM”),
    the New York Independent System Operator, Inc. (“NYISO”),
    Consolidated Edison Company of New York, Inc. (“ConEd”),
    Public Service Electric & Gas Company (“PSE&G”), PSE&G
    Energy Resources & Trading L.L.C., and the New Jersey
    Board of Public Utilities. Order Approving Contested
    Settlement and Denying Rehearing, 
    132 FERC ¶ 61,221
    (2010). This settlement ended protracted litigation over how
    to transition transmission service agreements entered into
    during the 1970s to the open access regime FERC created for
    transmission lines in its Order No. 888. Promoting Wholesale
    Competition Through Open Access Non-Discriminatory

    Stranded Costs by Public Utilities and Transmitting Utilities,
    
    61 Fed. Reg. 21,540
     (May 10, 1996) (“Order No. 888”).
    NRG Power Marketing, L.L.C., which objected to the
    approved settlement, petitions for review of FERC’s order
    3
    approving the contested settlement and of FERC’s order
    granting in part and denying in part NRG’s request for
    rehearing. See Order on Rehearing & Motions, 
    135 FERC ¶ 61,018
     (2011). In the settlement proceedings and its request
    for rehearing, NRG objected to the settlement, which gives
    ConEd transmission rights not available to other market
    participants, arguing that it violated FERC’s open-access
    principles as explained in Order No. 888, and that FERC’s
    rationales to justify the settlement as just and reasonable and
    not unduly discriminatory were flawed and not supported by
    substantial evidence. For the reasons set forth below, we
    deny NRG’s petition for review, concluding that FERC did
    not act arbitrarily or capriciously in approving an agreement
    that did not conform to PJM’s open-access transmission tariff,
    and that FERC’s justifications for approving the agreement
    were reasonable and supported by substantial evidence.
    I.     BACKGROUND
    A. Statutory and Regulatory Background
    Historically, electric utilities owned generation,
    transmission, and distribution facilities, and sold these three
    services as part of a “bundled” package. Transmission Access
    Policy Study Group v. FERC, 
    225 F.3d 667
    , 681 (D.C. Cir.
    2000). But as transmission technologies improved and
    alternative power suppliers emerged, a wholesale energy
    market developed, giving wholesale energy consumers new
    sources for competitively priced power. 
    Id.
     at 681–82.
    Utility ownership and control of transmission lines, however,
    remained a barrier to the development of this market. 
    Id. at 682
    . Recognizing that utilities that owned and controlled
    transmission lines had a profit-maximizing motive to restrict
    access to their transmission lines, FERC promulgated
    regulations aimed at “unbundling” transmission services from
    4
    the other services a utility offered and opening access to the
    transmission lines on equal terms. 
    Id.
     Thus, under its
    statutory authority to remedy unduly discriminatory or
    preferential rates, practices, or contracts affecting public
    utility rates for transmission in interstate commerce, see 16
    U.S.C. §§ 824d–e, FERC issued Orders No. 888 and 889 to
    “requir[e] all public utilities owning and/or controlling
    transmission facilities to offer non-discriminatory open access
    transmission service.” Transmission Access Policy Study
    Group, 225 F.3d at 682 (internal citation omitted). In Order
    No. 888, FERC also urged utilities to consider creating
    Independent System Operators (“ISOs”) and Regional
    Transmission Operators (“RTOs”), entities that control and
    operate all transmission services in a particular region
    independent of the utilities that own the transmission lines.
    See Braintree Electric Light Dep’t v. FERC, 
    550 F.3d 6
    , 8
    (D.C. Cir. 2008).
    As part of Order No. 888, FERC required every
    transmission-owning public utility to file a non-discriminatory
    open access transmission tariff (“OATT”) that was either
    consistent with or superior to a pro forma open-access
    transmission tariff contained in Order No. 888. See 61 Fed.
    Reg. at 21,619, 21,693–94, 21,706–17; see also Preventing
    Undue Discrimination and Preference in Transmission
    Service, 
    72 Fed. Reg. 12,266
     (Mar. 15, 2007) (“Order 890”)
    (amending the pro forma open access transmission tariff
    implemented by Order No. 888). The pro forma open access
    transmission tariff contains the minimum terms and
    conditions for non-discriminatory transmission service, and
    every transmission-owning public utility must abide by the
    tariff in providing transmission services to itself and others.
    Transmission Access Policy Study Group, 225 F.3d at 727.
    Although FERC did not abrogate existing contracts in Order
    No. 888, it noted that any new service taken upon expiration
    5
    would be considered new service and governed by the
    relevant open access transmission tariff.     Sacramento
    Municipal Utility District v. FERC, 
    428 F.3d 294
    , 296 n.4
    (D.C. Cir. 2005) (citing Order No. 888).
    Of relevance to this case, § 2.2 of the pro forma tariff
    addresses transmission service agreements that pre-dated the
    issuance of Order No. 888. See 61 Fed. Reg. at 21,709.
    Entities taking new service after expiration of their firm
    transmission service contract would be entitled to the right
    provided under § 2.2, entitled “Reservation Priority For
    Existing Firm Service Customers,” which provides:
    Existing firm service customers (wholesale
    requirements and transmission-only, with a contract
    term of one-year or more), have the right to continue
    to take transmission service from the Transmission
    Provider when the contract expires, rolls over or is
    renewed. This transmission reservation priority is
    independent of whether the existing customer
    continues to purchase capacity and energy from the
    Transmission Provider or elects to purchase capacity
    and energy from another supplier. If at the end of the
    contract term, the Transmission Provider’s
    Transmission System cannot accommodate all of the
    requests for transmission service the existing firm
    service customer must agree to accept a contract term
    at least equal to a competing request by any new
    Eligible Customer and to pay the current just and
    reasonable rate, as approved by the Commission, for
    such service. This transmission reservation priority
    for existing firm service customers is an ongoing right
    that may be exercised at the end of all firm contract
    terms of one-year or longer.

    Id.
    B. Factual and Procedural Background
    In the 1960s and 1970s, ConEd, an electric utility that
    primarily serves New York City, negotiated with PSE&G, a
    New Jersey utility, to jointly address the supply problems of
    northern New Jersey and New York City. This eventually led
    to two separate transmission service agreements (“TSAs”)
    between ConEd and PSE&G. ConEd and PSE&G executed
    the first of these agreements in 1975, which provided that
    ConEd would supply 400 MW from one of its upstate New
    York generators to PSE&G’s customers in northern New
    Jersey, while PSE&G would supply 400 MW from one of its
    New Jersey generators to ConEd’s customers in New York
    City. The second agreement was executed in 1978 and
    provided for a similar exchange in which ConEd would
    provide 600 MW from one of its upstate generators to
    PSE&G’s territory in New Jersey, while PSE&G would
    supply the same amount of energy from its New Jersey
    territory to New York City. Because of these agreements,
    ConEd discontinued plans to build new transmissions
    facilities into New York City, and ConEd and PSE&G agreed
    to construct or modify facilities to effectuate the TSAs. These
    agreements remained effective after FERC issued Order No.
    888, although ConEd’s transmission system became part of
    the New York Independent System Operator and PSE&G’s
    transmission system became part of PJM Interconnection, a
    regional transmission operator whose territory includes New
    Jersey.
    After ConEd and PSE&G ceded control of their
    transmission systems to NYISO and PJM, ConEd filed a
    complaint with FERC alleging that PSE&G, NYISO, and
    PJM were failing to honor the 1975 and 1978 TSAs, which
    7
    were grandfathered agreements under the pro forma open
    access transmission tariffs. After protracted litigation, the
    parties, per FERC’s directive, filed an operating protocol
    governing how the 1970s TSAs would be effectuated under
    the open access transmission tariffs, although the parties did
    not agree on all terms of the protocol. See Consolidated
    Edison Co. of New York v. Public Service Electric and Gas
    Co., 
    111 FERC ¶ 61,228
    , 62,040 (2005). FERC nevertheless
    approved that protocol. 
    Id. at 62,042
    . The 1975 and 1978
    TSAs and the then-effective operating protocol, however,
    were set to expire in 2012.
    Because of the impending expiration date on these TSAs,
    PJM and ConEd entered into replacement agreements, which
    they styled as § 2.2 roll-over agreements, with an effective
    date of 2012. In April 2008, PJM filed two non-conforming
    open access transmission tariff roll-over agreements with
    FERC to replace the two respective 1970s TSAs (collectively,
    the opinion will refer to these new agreements as “the 2008
    TSAs”), along with a new Schedule to the protocol. A day
    later NYISO filed a joint operating agreement protocol (“JOA
    protocol”) on an informational basis with FERC.
    In August 2008, FERC accepted and suspended the 2008
    TSAs and JOA protocol. It also set the matter for hearing and
    suspended the hearing to give the parties the opportunity to
    engage in settlement discussions before a settlement judge,
    and directed NYISO to formally file the 2008 JOA protocol.
    After extensive negotiations, the parties filed a settlement in
    which they modified the 2008 TSAs and JOA protocol and
    agreed that service under the 2008 TSAs would be rolled over
    under § 2.2 of PJM’s open access transmission tariff. The
    JOA protocol that FERC ultimately approved allows ConEd
    to submit contract elections in NYISO’s day-ahead market for
    the 400 MW and 600 MW transactions, and requires NYISO
    8
    and PJM to establish flow schedules across the transmission
    lines entering New York City from New Jersey (“the New
    York City feeders”).
    Allowing ConEd the ability to elect 1000 MW across the
    New York City feeders concerned FERC’s trial staff, who
    initially opposed the settlement. FERC’s trial staff opined
    that the settlement would “render a substantial amount of
    transmission capacity unavailable for other customers, while
    providing preferential service to a limited number of parties,”
    an issue that was particularly acute given the “extremely
    limited” transmission capacity into and out of New York City.
    NRG also filed comments opposing the settlement. Joint
    Appendix 386. Because the settlement was contested, the
    settlement judge certified the settlement to FERC without
    making a determination on the merits.
    In February 2010, FERC issued an order stating that it
    was unable to approve the settlement because the record was
    inadequate for FERC to decide certain contested legal issues,
    and establishing a briefing schedule. Several parties filed
    briefs or motions for late intervention and comments,
    including the parties to the settlement and NRG, the New
    York Public Service Commission, and PJM’s Market
    Monitor, among others. In March 2010, NRG filed a request
    for rehearing and for clarification of the briefing order,
    asserting, among other things, that the record was insufficient
    for a finding on the settlement.
    FERC approved the contested settlement by order on
    September 16, 2010, noting that “the [s]ettlement is a just and
    reasonable means for ConEd to obtain a continuation of its
    grandfathered transmission service.” PJM Interconnection,
    L.L.C. v. Public Service Electric & Gas Co., 
    132 FERC ¶ 61,221
    , 62,236 (2010). In approving the settlement, 
    FERC
                    9
    made determinations on several contested issues. First, FERC
    determined that the 1970s TSAs were agreements for firm
    service, and were therefore eligible for roll-over under § 2.2
    of PJM’s open access transmission tariff. Id. at 62,239.
    Second, FERC determined that the unique circumstances
    under which the PJM and NYISO would provide the service
    required under the 2008 TSAs warranted non-conforming
    open access transmission tariff service agreements.
    Specifically, FERC concluded that the agreements
    interpreting the JOA protocol were necessary to provide
    reliable service to ConEd. Id. at 62,241. In determining that
    ConEd was eligible for non-conforming service, FERC
    concluded that ConEd was not receiving an undue preference
    and that no other entity would be unduly discriminated
    against by approving that service. Id. at 62,241, 62,243.
    FERC also determined that the 2008 TSA did not have a
    significant adverse effect on the rights of and prices paid by
    other parties, id. at 62,244–45, and that the 2008 TSAs did not
    violate any provisions of PJM’s or NYISO’s open access
    transmission tariffs. Id. at 62,245–46. In approving the
    contested settlement, FERC denied NRG’s request for
    rehearing or clarification, explaining that all issues raised in
    the hearing and briefing orders had been addressed, and that
    the record, through briefing, was adequately developed for
    FERC to approve the settlement. Id. at 62,246.
    NRG filed a request for rehearing of FERC’s order
    approving the settlement, arguing that FERC erred in
    approving the settlement for several reasons, including that
    the 1970s TSAs were not eligible to be rolled over and that
    FERC’s approval of the settlement was not based on
    substantial evidence. See PJM Interconnection, L.L.C. v.
    Public Service Electric & Gas Co., 
    135 FERC ¶ 61,018
    ,
    61,060 (2011). FERC, in an order addressing each of NRG’s
    arguments, largely denied NRG’s request for rehearing. 
    Id.
     at
    10
    61,066. Although it granted NRG’s request to accept an
    affidavit it had previously filed, it explained that the affidavit
    did not change its determinations. 
    Id.
    After FERC denied rehearing, NRG timely petitioned this
    Court for review of these orders. First, NRG asserts that
    FERC’s order approving the settlement is arbitrary and
    capricious because it conflicts with FERC’s rules and
    precedents. This argument, essentially, is that FERC cannot
    approve non-conforming agreements that deviate from the
    relevant OATT for an individual utility. Second, NRG asserts
    that FERC’s order was not supported by substantial evidence,
    and that even if FERC based its decision on an adequate
    record, its determination that the approved settlement was not
    unduly discriminatory did not reflect reasoned decision-
    making.
    II.    ANALYSIS
    When reviewing FERC’s approval of a contested
    settlement, we must determine whether FERC has supplied a
    “reasoned decision” that is supported by “substantial
    evidence.” NorAm Gas Transmission Co. v. FERC, 
    148 F.3d 1158
    , 1162 (D.C. Cir. 1998) (quoting 
    18 C.F.R. § 385.602
    (h)(1)(i)).    If FERC’s approval is “arbitrary,
    capricious, an abuse of discretion, or otherwise not in
    accordance with law,” 
    5 U.S.C. § 706
    (2)(A), or “unsupported
    by substantial evidence,” 
    id.
     § 706(2)(E), we must set aside its
    approval of the contested settlement. Exxon Co. v. FERC,
    
    182 F.3d 30
    , 37 (D.C. Cir. 1999). In reviewing FERC’s
    approval of the settlement, we note that “when agency orders
    involve complex scientific or technical questions,” as is the
    case here, “we are particularly reluctant to interfere with the
    agency’s reasoned judgments.” B&J Oil & Gas v. FERC, 
    353 F.3d 71
    , 76 (D.C. Cir. 2004).
    11
    A. Approval of Non-Conforming OATT Filings
    NRG’s first challenge to FERC’s approval of the
    settlement is that the settlement is inconsistent with FERC’s
    open access orders, our precedents, and § 2.2 of the pro forma
    OATT itself. As NRG conceded at oral argument, this
    challenge is essentially that FERC can only approve roll-over
    service under § 2.2 that conforms to the relevant OATT.
    Stated differently, as NRG did in its Request for Rehearing of
    FERC’s order approving the settlement, NRG argues that
    “[p]recedent dictates that a transmission provider cannot
    rollover a non-conforming agreement.” Joint Appendix 791.
    We disagree, and conclude that FERC’s approval of the
    contested settlement, and its rationale for rejecting NRG’s
    arguments, was not a departure from its orders, precedents, or
    terms of § 2.2 of PJM’s OATT, particularly in light of the
    substantial deference we give to FERC in interpreting its own
    orders. See Consumers Energy Co. v. FERC, 
    428 F.3d 1065
    ,
    1067–68 (D.C. Cir. 2005).
    NRG is correct that Order No. 888 requires that an entity
    rolling over service under § 2.2 must take that service under
    the terms of the applicable OATT. Indeed, FERC itself noted
    this fact, explaining in its order approving the settlement that
    “[t]he roll-over provisions of Order No. 888 and 890 do not
    provide a right for a service other than OATT service,” 132
    FERC at 62,241, and stating in its order denying rehearing
    that it “agree[s] with NRG that section 2.2 of the pro forma
    OATT does not provide a right for service other than OATT
    service.” 135 FERC at 61,062. And in its order approving the
    settlement, FERC explains that “the 2008 1000 MW TSA will
    be subject to PJM’s OATT.” 132 FERC at 61,241.
    12
    Notwithstanding FERC’s acknowledgement that ConEd’s
    service must be taken under the terms of PJM’s OATT, FERC
    nevertheless approved a settlement that included elements—
    specifically, the JOA protocol—that do not conform to PJM’s
    OATT. See id. FERC’s rationale in approving these elements
    was that the JOA protocol was necessary “to enable PJM and
    NYISO to manage [unintended loop flows]” and “to provide
    for a continuation of” reliable service. Id. NRG takes issue
    with FERC’s approval of the JOA protocol, asserting that
    FERC contravened its open access principles by approving a
    non-conforming agreement that gives ConEd rights that are
    not available to other market participants.
    In response to this contention, FERC explained in the
    order approving the settlement that “OATT services can be
    conforming or non-conforming,” and determined that the JOA
    protocol is necessary “due to the operational issues raised by
    the service that cannot be accommodated under standard
    OATT service,” explaining that the terms and conditions of
    the settlement order “reflect the needs of [PJM and NYISO]
    in order to be able to provide service to ConEd.” 135 FERC
    at 61,062–63.      Intervenor PJM further elaborated on the
    operational difficulties present in this case, an explanation we
    find helpful in deciding whether FERC’s interpretation of
    Order No. 888 is reasonable. According to PJM, the
    operational challenge in transitioning the 2008 TSAs to PJM’s
    OATT is that, under the TSAs, energy originates in New York
    in NYISO’s territory, transmits across New Jersey through
    PJM’s territory, and is then delivered to New York City in
    NYISO’s territory. Intervenor Br. at 13. PJM explains that
    because of how it provides its “through-and-out” service, it
    would not be able to provide service when the “source” and
    “sink” of the energy occurred within NYISO. Id. at 13–15;
    see also 132 FERC at 62,243 (explaining that “the service
    PJM provides to ConEd differs from typical through-and-out
    13
    service because the source and sink are in the same system
    (i.e., New York)”). PJM explains that this operational
    challenge was at the core of the litigation that underlay the
    settlement agreement, and that FERC’s order on the second
    phase of that litigation—which sets out guidance on the terms
    to be included in a protocol to ensure that service under the
    2008 TSAs was effectuated consistent with open access
    principles—formed the basis for the JOA protocol that FERC
    eventually approved as part of the settlement agreement.
    Intervenor Br. at 14–17; see Initial Decision on Phase II
    Issues, 
    103 FERC ¶ 63,047
     (2003) (Presiding Judge’s
    Decision on Phase II issues), aff’d in part and modified in
    part, Opinion and Order on Initial Decision, 
    108 FERC ¶ 61,120
     (2004) (FERC’s order on review of Presiding Judge’s
    Phase II Decision).
    Instead of acknowledging this operational difficulty,
    NRG argues, in absolute terms, that FERC cannot approve the
    rollover of non-conforming OATT agreements, explaining
    that FERC’s open access orders “provide that, upon
    expiration of a customer’s grandfathered, pre-open access
    transmission contract, the customer’s service going forward
    will be governed by an applicable non-discriminatory
    OATT.” Pet’r Br. at 25. NRG contends that because the
    2008 TSAs do not conform to PJM’s OATT, they contravene
    FERC’s open access principles, and FERC’s order approving
    the settlement must be vacated. NRG supports this argument
    by citing to our opinion in Transmission Access Policy Study
    Group, in which we noted that open access is the “essence” of
    Order No. 888 and explained that under Order No. 888
    “utilities must . . . provide access to their transmission lines to
    anyone purchasing or selling electricity in the interstate
    market on the same terms and conditions as they use their
    own lines.” 225 F.3d at 681.
    14
    But while NRG asserts, in broad terms, that open access
    is a fundamental “tenet” or “principle” of Order No. 888, it
    has not persuasively cited a specific provision of Order No.
    888 or any language in § 2.2 of the pro forma OATT that
    prevents FERC from approving any rolled-over transmission
    service agreement filings that deviate from the OATT. Nor
    has NRG cited any FERC precedent in which FERC stated
    that the rollover of non-conforming transmission service
    agreements—even those that grant rights to one market
    participant that are not given to others—per se violate its open
    access orders.
    To the contrary, FERC has approved agreements in the
    past that allow deviations from filed OATTs. In PJM
    Interconnection, L.L.C. & Carolina Power & Light Co., 
    134 FERC ¶ 61,048
     (2011), FERC approved a Joint Operating
    Agreement between neighboring RTOs, finding that “the Joint
    Operating Agreement provides for a superior method of
    congestion management” compared to the OATT.

     (2004), FERC explained that when limited available
    transfer capability existed on a system between RTOs, RTOs

    Agreement between RTOs to allocate capacity did not violate

    the total of the available . . . capacity under one RTO’s
    OATT”). 1
    1
    In addition to these two orders, FERC, both in its order denying
    rehearing and in its Respondent Brief before us, cited four other
    orders in which it approved non-conforming agreements. See 135
    15
    Although NRG acknowledges that these orders “did
    approve tariffs with non-conforming provisions,” Pet’r Reply
    Br. at 12, it argues that the Joint Operating Agreements at
    issue in these cases did not grant a preference to any
    individual entity, unlike the 2008 TSAs and JOA protocol
    approved here. And, NRG notes, FERC’s precedent places a
    high burden on a transmission provider seeking FERC’s
    acceptance of a non-conforming agreement “to justify and
    explain that any non-conforming aspects of the agreement are
    ‘consistent with or superior to’ the relevant pro forma
    agreement.” Pet’r Reply Br. at 13 (quoting Southwest Power
    Pool, Inc., 
    132 FERC ¶ 61,159
    , 61,807 (2010)).
    We agree with NRG that these orders are not directly on
    point but do not find this dispositive of whether FERC can
    approve a non-conforming agreement between PJM and
    NYISO to effectuate the 2008 TSAs to ConEd, particularly
    given the operational challenges presented. NRG addresses
    neither the operational challenges that exist in providing
    FERC at 61,062; Resp’t Br. at 26–27. These agreements, however,
    were non-conforming generator interconnection agreements, which
    are covered by FERC’s Order No. 2003. See Southern California
    Edison Co., 
    133 FERC ¶ 61,200
    , 62,001 (2010). Order No. 2003
    expressly states that FERC may approve non-conforming generator
    interconnection agreements “where reliability concerns, novel legal
    issues, or other unique factors would call for non-conforming
    agreements,” 
    id. at 62
    ,001–02, while neither Order No. 888 nor
    subsequent orders clarifying FERC’s open access policies explicitly
    state that FERC may approve non-conforming agreements. Thus,
    we agree with NRG that these four orders approving non-
    conforming generator interconnection agreements do not
    persuasively demonstrate that FERC may approve agreements that
    do not conform to the relevant OATT. But the fact that Order No.
    888 does not include such an express provision does not preclude
    FERC from approving non-conforming agreements in Order No.
    888, for the reasons we explain in the body of this opinion.
    16
    service to ConEd through two independent transmission
    operators, nor the fact that FERC has recognized the necessity
    of non-conforming agreements for a small number of
    individuals “with specific reliability concerns, novel legal
    issues, or other unique factors.” Southwest Power Pool, Inc.,
    132 FERC at 61,807. As we have stated before, when entities
    before FERC present “intensely practical difficulties” that
    demand a solution, FERC “must be given the latitude to
    balance the competing considerations and decide on the best
    resolution.” Blumenthal v. FERC, 
    552 F.3d 875
    , 885 (D.C.
    Cir. 2009). Given the operational difficulties in effectuating
    the rolled-over service through two neighboring transmission
    operators, we do not read FERC’s orders so strictly as to deny
    FERC discretion to approve transmission service agreements
    that do not completely conform with the relevant OATT.
    NRG also attempts to demonstrate inconsistency by
    citing FERC’s orders regarding the Sacramento Municipal
    Utility District, orders that we affirmed in Sacramento
    Municipal Utility District v. FERC, 
    428 F.3d 294
     (D.C. Cir.
    2005) (“SMUD I”), and in Sacramento Municipal Utility
    District v. FERC, 
    474 F.3d 797
     (D.C. Cir. 2007) (“SMUD
    II”). In SMUD I, we upheld FERC’s determination that under
    the California Independent System Operator’s (“CAISO”)
    tariff, which did not include a section equivalent to § 2.2 of
    the pro forma tariff, a municipal customer could not extend
    the terms of its contract or invoke the right of first refusal
    under Order No. 888. 428 F.3d at 297. In SMUD II, we
    upheld FERC’s determination that CAISO and other
    California utilities did not unduly discriminate when they
    negotiated with the Western Area Power Administration to
    continue transmission service outside the CAISO tariff while
    at the same time requiring the municipality to take service
    under CAISO’s tariff. 
    474 F.3d at 804
    . Because Western
    owned and operated a segment of a transmission line that
    17
    made up the Pacific Intertie, FERC had approved the
    transmission agreement as a “unique agreement which is
    beneficial to all the parties,” and we determined that it was
    not unduly discriminatory for FERC to do so because the
    municipality did not own any portion of the Intertie. 
    Id. at 799, 804
     (quoting Pacific Gas & Electric Co., 
    109 FERC ¶ 61,255
    , 62,212–13).
    The key distinction between FERC’s orders in the SMUD
    cases and its order approving the settlement in this case is
    that, in this case, FERC expressly approved the transmission
    service agreement agreed on by the parties to the settlement,
    even though that agreement included elements that did not
    conform to PJM’s OATT. In contrast, FERC had not
    approved a similar agreement in SMUD I, but had only
    determined that the municipality had not argued any basis for
    extending its expired grandfathered transmission contract
    under CAISO’s tariff. No inconsistency exists between
    denying an entity the ability to extend its grandfathered
    transmission service and approving a new transmission
    service agreement, taken under the relevant OATT, which
    includes a protocol that does not conform to the relevant
    OATT. This is particularly true when the relevant OATT
    includes a roll-over provision that was not present in
    CAISO’s tariff, and when providing the rolled-over service
    involves operational challenges that were not evident in the
    case of the municipality in SMUD I and II. Although NRG’s
    argument would have more weight had FERC rejected a non-
    conforming agreement between the municipality and CAISO
    as violating Order No. 888’s open-access principles, such was
    not the case in the SMUD orders, leaving NRG’s argument as
    simply a challenge to FERC’s ability to approve any
    transmission service agreement that does not conform to the
    relevant OATT. Moreover, the fact that FERC approved the
    transmission exchange agreement in SMUD II based on
    18
    unique circumstances demonstrates that it has exercised
    discretion in the past to approve transmission agreements that
    do not conform to the relevant OATT.
    Finally, NRG argues that it is illogical for FERC to
    approve a non-conforming agreement for roll-over service
    under § 2.2, because § 2.2 of PJM’s OATT does not provide a
    right to any service other than OATT service. Pet’r Br. at 35–
    38. But as FERC explained in its order denying rehearing,
    “ConEd will schedule the service in accordance with the PJM
    OATT and will pay all of the charges prescribed by the
    OATT for such service.” 135 FERC at 61,062. FERC’s
    interpretation of § 2.2 as not preventing it from approving
    non-conforming service is plausible, and we thus do not
    disturb FERC’s approval of the settlement on this ground,
    particularly because we afford FERC substantial deference in
    its interpretation of its own orders. Consumers Energy Co.,
    
    428 F.3d at
    1067–68. FERC’s interpretation of Order No.
    888 as not foreclosing nonconforming transmission service
    agreements is not “plainly erroneous or inconsistent” with its
    open access orders or, as NRG argues, with § 2.2 of the pro
    forma OATT. See id. at 1067. We therefore defer to FERC’s
    interpretation of its orders as allowing the non-conforming
    2008 TSAs and JOA protocol it approved in this case.
    Of course, our conclusion that FERC has discretion to
    approve a transmission service agreement that does not
    conform to the applicable OATT does not excuse FERC from
    making the required determinations under §§ 205 and 206 of
    the Federal Power Act that the agreements are just and
    reasonable and not unduly discriminatory, a determination
    that FERC must base on substantial evidence. See 16 U.S.C.
    §§ 824d–e; id. § 825l(b). Having concluded that FERC did
    not act arbitrarily or capriciously by the mere fact that it
    approved a non-conforming agreement, we now turn to
    19
    NRG’s contentions that the approved settlement is unduly
    discriminatory and that FERC did not base its determination
    on substantial evidence.
    B. Undue Discrimination
    In its petition for review, NRG argues that FERC failed
    to demonstrate that its orders are not unduly discriminatory.
    FERC asserts, however, that NRG waived its undue
    discrimination argument because it did not raise the issue in
    its request for hearing, as it was required to do under § 313 of
    the Federal Power Act. See 16 U.S.C. § 825l(b) (“No
    objection to the order of the Commission shall be considered
    by the [reviewing] court unless such objection shall have been
    urged before the Commission in the application for rehearing
    unless there is reasonable ground for failure so to do.”). We
    have explained that § 313 is construed strictly, and that
    “objections not explicitly presented in proceedings below, but
    arguably ‘implicit’ in other objections, were not properly
    preserved.” Entergy Services, Inc. v. FERC, 
    391 F.3d 1240
    ,
    1247 (D.C. Cir. 2004) (citing Kelley ex rel. Mich. Dep’t of
    Nat’l Resources v. FERC, 
    96 F.3d 1482
    , 1488 (D.C. Cir.
    1996)).
    When FERC approved the settlement agreement, it
    addressed whether the 2008 TSAs and JOA protocol unduly
    discriminated against other market participants. See 132
    FERC at 62,241–44. Responding to NRG’s arguments that
    the JOA protocol was unduly discriminatory “because it
    would carve up scarce transmission resources without
    allowing open access to competitors” and because it gives
    ConEd unique congestion rights not available to other
    competitors, FERC determined that the agreement was not
    unduly discriminatory because no other entities were similarly
    20
    situated, i.e., requesting service where the source and sink
    were in NYISO. 
    Id. at 62,242
    .
    Although FERC’s order clearly addressed this issue
    under a subheading entitled “undue discrimination,” NRG’s
    request for rehearing does not directly raise the issue of undue
    discrimination. Instead, NRG takes issue with the factual
    findings that underlie FERC’s determination that the
    agreement was not unduly discriminatory, arguing that FERC
    “erred in asserting that other parties are free to take the same
    service as ConEd,” explaining that FERC’s assertion was
    incorrect because “the JOA is tailored to meet the specific
    needs of ConEd.” Joint Appendix 817.
    In its reply brief, NRG asserts that it properly preserved
    its undue discrimination argument in its request for rehearing,
    citing to sections in which it “object[ed] to the manner in
    which the JOA Protocol discriminates against all market
    participants other than ConEd by not allowing them to
    schedule counterflows across the NYC feeders,” and in which
    it argued “that the JOA Protocol creates ‘undue harm’ to
    pricing in NYISO and PJM and that [FERC] wrongly
    discounted the material impact of such harms to NRG.” Pet’r
    Reply Br. at 20. NRG also cites pages in its request for
    rehearing in which it uses variations on the words
    “discriminatory” and “preferential.” 
    Id.
    We agree with NRG that it has properly raised these
    issues in its petition for review. While it is true that NRG did
    not explicitly include a subheading for “Undue
    Discrimination” in its request for rehearing, as it has in its
    petition for review, the substance of its arguments in both
    filings is sufficiently similar to preserve its objection before
    us. NRG argues undue discrimination in its petition for
    review based on: (a) the fact that “[t]he 2008 1000 MW TSAs
    21
    and JOA Protocol are discriminatory in operation because
    they give ConEd a unique and preferential ability to schedule
    physical power flows across the NYC Feeders,” while all
    other market participants are required to schedule flows
    between PJM and NYISO across the “generic PJM-NYISO
    proxy bus,” Pet’r Br. at 43 (internal quotation marks omitted);
    and, (b) the harm to NRG’s operations resulting from
    economically inefficient flows and the harm to the PJM and
    NYISO markets resulting from price distortions created by the
    settlement. See 
    id.
     at 44–46, 48–50. NRG asserted these
    same points in its request for rehearing, and its request for
    rehearing thus “gave notice to the Commission with sufficient
    clarity regarding the grounds on which it urged
    reconsideration.” Belco Petroleum Corp. v. FERC, 
    589 F.2d 680
    , 683 (D.C. Cir. 1978) (applying the Natural Gas Act’s
    judicial review provision, which is worded identically to that
    of the Federal Power Act).
    Although we conclude that NRG has preserved the undue
    discrimination argument it advances in its petition for review,
    we reject that argument on its merits. We agree with FERC
    that “NRG’s claim of injury is not that it seeks the particular
    service which ConEd is getting,” Resp’t Br. at 33, but instead
    that the settlement agreement reduces NRG’s access to the
    transmission lines and harms its operations. We similarly
    conclude that the undue discrimination claim NRG raises is,
    in reality, simply a challenge to FERC’s reasoning in finding
    the settlement agreement just and reasonable, and to the
    sufficiency of the evidence upon which FERC relied. As with
    its argument that FERC cannot approve non-conforming
    agreements, NRG’s failure to address the operational
    challenges involved in effectuating the 2008 TSAs is fatal to
    its undue discrimination claim. To prevail on an undue
    discrimination challenge, NRG must demonstrate that it and
    ConEd are similarly situated for purposes of the approved
    22
    settlement. See Ohio Power Co. v. FERC, 
    744 F.2d 162
    , 165
    n.3 (D.C. Cir. 1984). NRG has not demonstrated that it or
    any other parties are similarly situated to ConEd and does not
    argue in its petition for review that any other entities aside
    from ConEd have requested through-and-out service that
    sources and sinks in the same area. Accordingly, we conclude
    that FERC did not unduly discriminate against NRG by
    approving the settlement agreement.
    C. Substantial Evidence
    Finally, we address NRG’s challenges to FERC’s
    reasoning and the sufficiency of the evidence upon which it
    based its decision. NRG first argues that FERC’s procedural
    history—the timing of its issuance of orders establishing
    hearings and briefing schedules—demonstrates that the record
    was insufficient.      NRG also contends that FERC’s
    determinations on several factual issues that led to FERC’s
    approval of the settlement were not based on substantial
    evidence. In addition to its argument that FERC did not base
    its decision on substantial evidence, NRG asserts different
    reasons why FERC’s decision to approve the settlement was
    arbitrary and capricious.        We find these arguments
    unpersuasive, and conclude that FERC’s order was well-
    reasoned and supported by substantial evidence.
    The procedural history does not demonstrate that FERC
    arbitrarily reversed course on whether the post-settlement
    record was insufficient, as NRG claims. After PJM and
    ConEd filed the 2008 TSAs and JOA protocol, which resulted
    from the litigation generated by ConEd’s initial 2002
    complaint, FERC issued an order on August 26, 2008,
    establishing a trial-type evidentiary hearing and settlement
    procedures on the justness and reasonableness of the TSAs.
    See PJM Interconnection L.L.C. & New York Independent
    23
    System Operator, Inc., 
    124 FERC ¶ 61,184
     (2008). In that
    order, FERC explained that the issues raised in protest to
    those TSAs raised questions of material fact that could not be
    resolved on the record before FERC at that time, and that
    FERC could not determine whether the TSAs and JOA
    protocol may be unjust, unreasonable, or unduly
    discriminatory. See 
    id. at 61,912
    . The hearing was never
    held, and the settlement FERC ultimately approved was filed
    on February 23, 2009. See PJM Interconnection L.L.C. &
    New York Independent System Operator, Inc., 
    130 FERC ¶ 61,126
     (2010). But before FERC approved the settlement, it
    issued an order establishing briefing schedules on February
    19, 2010, stating that it found the state of the record at the
    time of that order insufficient to allow it to resolve the merits
    of some of the contested issues. 
    Id. at 61,623
    .
    Nowhere in the order establishing a briefing schedule did
    FERC state that the factual record was insufficient. Indeed,
    FERC acknowledged the settlement had resolved some of the
    issues, including factual issues, that had motivated the order
    FERC issued in 2008 establishing a hearing. 
    Id. at 61,626
    .
    FERC noted that it was establishing a briefing schedule
    because these issues appeared to raise legal, rather than
    factual issues, and reserved for itself “the right to establish
    additional procedures including hearing procedures if
    necessary.” 
    Id.
     That FERC received the briefing it requested
    and made determinations on contested issues, without
    gathering additional evidence or invoking its reserved right to
    establish a hearing, does not demonstrate, by itself, that FERC
    “reversed course on the sufficiency of the record.” Pet’r Br.
    at 41. Moreover, FERC’s decision not to hold an evidentiary
    hearing is within its discretion, and it may “properly deny an
    evidentiary hearing if the issues, even disputed issues, may be
    adequately resolved on the written record, at least where there
    is no issue of motive, intent or credibility.” Pacific Gas &
    24
    Electric Co. v. FERC, 
    306 F.3d 1112
    , 1119 (D.C. Cir. 2002).
    NRG has not alleged that issues of motivation, intent, or
    credibility were present in the approval of the settlement, and
    we therefore do not find a procedural flaw in FERC’s decision
    to approve the settlement based on the record as it existed at
    that time.
    We now turn to NRG’s substantive challenges to the
    sufficiency of the evidence upon which FERC relied in
    approving the settlement, noting that “[s]ubstantial 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) (quoting
    Colorado Interstate Gas v. FERC, 
    599 F.3d 698
    , 704 (D.C.
    Cir. 2010)). In its request for rehearing, NRG argued that
    approving the settlement agreement would impermissibly
    distort prices in NYISO’s energy market, and that FERC did
    not adequately explain how the 2008 TSAs and JOA protocol
    could be just and reasonable in light of this distortion. NRG
    emphasized the harm to its own operations resulting from the
    settlement, maintaining that FERC unreasonably discounted
    the loss NRG would incur from even a small percentage of
    inefficient power flows. NRG also asserted that FERC’s
    reference to other pending proceedings that may address the
    NYISO-PJM seams issues did not make FERC’s
    determination on the settlement agreement’s impact on prices
    reasoned decisionmaking, explaining that ConEd’s
    preferential agreements would still exist and that FERC was
    legally bound to address problematic elements in the instant
    settlement proceedings.
    FERC responded that the 2008 TSAs were economic in
    roughly 88 percent of hours, and that the harm caused by the
    remaining 12 percent did not outweigh the benefits the
    settlement conferred, particularly because the settlement
    25
    provided substantially lower prices to customers in New York
    in 88 percent of hours. 135 FERC at 61,063–64. Noting that
    “the perfect cannot be the enemy of the good,” FERC
    explained that until the RTOs addressed loop flow issues, the
    settlement provided a reasonable method of managing loop
    flows and providing overall benefits to customers. Id. at
    61,064.
    In its petition for review, NRG first argues that FERC
    weighed the justness and reasonableness of the settlement
    against the wrong baseline, asserting that FERC should have
    measured the justness and reasonableness of the settlement
    against the alternative of requiring all market participants,
    including ConEd, to take under conforming OATTs. This
    argument, however, is merely a collateral attack on FERC’s
    ability to approve non-conforming agreements, and again
    ignores the operational difficulties that prompted the
    underlying litigation and settlement in the first place.
    Neither are we persuaded by NRG’s argument that FERC
    did not engage in a reasoned analysis in weighing the harms
    and benefits of approving the settlement. NRG cites to
    FERC’s explanation in its order denying rehearing where
    FERC explained that the settlement would improve flows in
    88 percent of hours, which NRG claims was not based on any
    evidence in the record. NRG explains that ConEd’s expert
    merely testified that prices in New York City were higher 88
    percent of the time than prices in New Jersey, and that the
    evidence attached to this expert’s affidavit actually
    demonstrated that, even absent the settlement, power would
    flow economically in 25 percent of those hours.
    Even if we were to accept that FERC’s statement that
    flows would “improve” in 88 percent of hours was an
    “exaggeration”—when FERC had previously stated that
    26
    “[b]oth the parties supporting the Settlement and NRG
    generally agree that the 2008 1000 MW TSAs are economic
    in roughly 88 percent of hours,” see 132 FERC at 62,241—
    this exaggeration does not render FERC’s reasoning arbitrary
    or capricious. See Pet’r Br. at 48. FERC’s order approving
    the settlement explained that the agreements were economic
    in 88 percent of hours, and that “when prices are lower in
    NYISO than PJM, the price differential usually is not great,
    but, when prices in NYISO are higher than PJM, they are
    substantially higher,” 132 FERC at 62,244, factors FERC
    relied on to approve the settlement. And in its order denying
    rehearing, FERC determined that the harm to NRG’s facility
    did not outweigh “the fact that the agreement results in
    substantially lower prices to customers in New York in 88
    percent of hours,” a factual finding that NRG has not
    attempted to dispute in its petition for review. 135 FERC at
    61,064.     Thus, apart from attempting to cast FERC’s
    statement about improving flows as an unreasonable
    exaggeration, NRG essentially requests us to review FERC’s
    balancing of competing interests. But as we have explained,
    we properly defer to policy determinations invoking FERC’s
    expertise in evaluating complex market conditions.
    Tennessee Gas Pipeline Co. v. FERC, 
    400 F.3d 23
    , 27 (D.C.
    Cir. 2005). In this case, “FERC reflected on the competing
    interests at stake to explain why it struck the balance it did,”
    and we will not reject its determination. Sacramento
    Municipal Utility District v. FERC, 
    616 F.3d 520
    , 541–42
    (D.C. Cir. 2010).
    When discussing the impact of the settlement on prices,
    FERC noted that other proceedings were already underway to
    address issues at the NYISO-PJM seam. See 132 FERC at
    62,245 (“NRG asserts that the JOA Protocol prevents
    economic power flows across the PJM-NYISO seam . . . [,
    but] we find that any problems with the PJM-NYISO seam,
    27
    including use of the single proxy bus for pricing, are beyond
    the scope of this proceeding.”). In its petition for review,
    NRG maintains that FERC’s attempt to kick the can down the
    road violates our precedent and fails to adequately respond to
    NRG’s and another objecting party’s argument that the
    settlement would interfere with a comprehensive resolution of
    the seams issue. NRG cites our opinions in NorAm Gas
    Transmission Co., 
    148 F.3d 1158
    , and SMUD II to support
    this argument, and also asserts that FERC “did not adequately
    grapple with NRG’s and DTE’s arguments that approving the
    Settlement Agreement may interfere with the establishment of
    a comprehensive non-discriminatory solution to the seams
    issues.” Pet’r Br. at 57.
    We disagree with NRG that FERC did not “adequately
    grapple” with NRG’s and DTE’s arguments. In its order
    denying rehearing, FERC explained that the results of the
    seams issues addressed in other proceedings would affect the
    settlement, stating that neither the 2008 1000 MW TSAs nor
    the JOA protocol would prevent PJM and NYISO from
    modifying their OATTs once the seams issues are resolved,
    and that if PJM amends its scheduling practice, that new
    practice would govern ConEd’s transmission service
    agreement. 135 FERC at 61,065 n.62. NRG responds that
    this explanation is dismissive of it and DTE’s arguments,
    because it only pointed to the possibility that PJM and NYISO
    would amend their OATTs in a way that affected the service
    to be provided under the settlement. But FERC was not being
    dismissive of these arguments; instead, it was balancing
    different problems in the face of uncertainty. Indeed, DTE’s
    statement is itself uncertain regarding the effects of the
    settlement, with DTE expressing concern that the settlement
    “may interfere with NYISO’s and PJM’s ability to establish a
    comprehensive interface pricing policy between the two
    regions.” Joint Appendix 787 (emphasis added). Given the
    28
    complexities in this case—both the operational difficulties in
    effectuating ConEd’s rolled-over service across two RTOs
    and the coordination issues between the two RTOs more
    generally—we conclude that FERC has appropriately
    considered the issues the petitioner and other entities raised
    during the settlement approval process, and defer to FERC in
    its decision on how to resolve these competing issues. That
    the settlement is not what petitioners or other entities in the
    market would have wanted does not undermine FERC’s
    approval of it. See Public Service Commission of Wisconsin
    v. FERC, 
    545 F.3d 1058
    , 1067 (D.C. Cir. 2008).
    NRG also has not persuaded us that our precedent
    forecloses FERC from citing the ongoing PJM-NYISO seams
    issue proceedings to justify its approval of the settlement. In
    SMUD II, we determined FERC acted reasonably in deciding
    that a municipality raising concerns over implementation of
    an OATT should participate in proceedings to redesign the
    tariff, rather than grandfather its pre-open access transmission
    service agreement. On this issue—whether FERC may refer
    to ongoing proceedings related to a contested settlement in
    order to justify that settlement—SMUD II is unpersuasive for
    the same reasons it failed to persuade on the issue of whether
    FERC can approve non-conforming agreements. In the
    SMUD cases, the municipality requested that we vacate and
    remand FERC’s order approving the termination of its long-
    term transmission contract. SMUD II, 
    474 F.3d at 800
    . We
    upheld FERC’s acceptance of the termination of the contract,
    explaining that its decision that the municipality must operate
    under the tariff during a comprehensive marketing redesign
    proceeding was “perfectly rational.” 
    Id. at 802
    . The
    distinction between the SMUD cases and the settlement here
    is that FERC approved the non-conforming agreement, which
    still requires ConEd to take under the rates of PJM’s OATT.
    Thus, we do not read SMUD I and II as stating that 
    FERC 29
    may never approve a non-conforming agreement when
    broader ongoing proceedings exist. Balancing an immediate
    short-term need to approve an agreement to address
    operational difficulties with broader market redesign
    proceedings to address pricing issues is the sort of challenge
    that requires a high level of technical expertise, and we
    properly defer to FERC’s informed discretion on that score.
    Transmission Access Policy Study Group, 225 F.3d at 714.
    We also fail to see how NorAm precludes FERC from
    citing other ongoing proceedings when approving this
    settlement. In NorAm, FERC had stated that the contested
    settlement proceedings in that case were not the appropriate
    forum to address one of the issues the petitioner had raised
    before this Court. 
    148 F.3d at 1163
    . We never spoke to
    whether FERC was incorrect in stating that the contested
    settlement proceedings were not the proper forum for all
    issues related to the petitioners challenge, but instead
    explained that because the goal of FERC’s natural gas
    pipeline open access orders was to remedy anticompetitive
    behavior by pipeline sellers, “it was incumbent upon [FERC],
    when considering the settlement offer, to give serious
    consideration to the alleged anticompetitive effects of
    Tennessee’s rate system.” 
    Id. at 1164
    .
    In this case, FERC seriously considered the
    anticompetitive effects of the settlement, determining that the
    settlement was justified in light of the unique operational
    challenges involved in effectuating the 2008 TSAs. In fact,
    the approach FERC used in approving the contested
    settlement is one of the four approaches that FERC
    established in Trailblazer Pipeline Co., 
    85 FERC ¶ 61,345
    (1998), which FERC issued in part as a response to our
    reversing it in NorAm. See 
    id. at 62
    ,340–41. Under the first
    approach explained in Trailblazer, FERC may, assuming an
    30
    adequate record, address each objection of a contesting party
    on the merits. 
    Id. at 62,342
    . If it finds that all the contesting
    parties’ objections lack merit, FERC may approve the
    settlement. 
    Id.
     FERC adopted that approach here, see 132
    FERC at 62,236 n.37, and addressed each of NRG’s
    objections in its order approving the settlement. Though
    NRG, unsurprisingly, disagrees with FERC’s determinations
    on the merits, we conclude that FERC was not dismissive of
    NRG’s objections when it discussed separate proceedings
    addressing the NYISO-PJM seam, but was instead explaining
    its decision in light of complex market conditions. We owe
    this evaluation deference. See Tennessee Gas Pipeline, 
    400 F.3d at 27
    .
    NRG also cites NorAm to argue that FERC’s finding that
    the settlement agreement was “freely negotiated” is
    insignificant. Pet’r Br. at 53. But this case is unlike NorAm
    or the other cases that motivated FERC to establish a
    contested settlement approval process. In those cases, we
    reversed FERC’s orders approving a settlement because
    FERC had relied on the consent of the settling parties without
    independently concluding that the settlement was just and
    reasonable or in the public interest. See NorAm, 
    148 F.3d at
    1164–65; Laclede Gas Co. v. FERC, 
    997 F.2d 936
    , 946 (D.C.
    Cir. 1993); Tejas Power Corp. v. FERC, 
    908 F.2d 998
    , 1003
    (D.C. Cir. 1990). We also observed that though FERC must
    independently conclude a settlement is just and reasonable,
    and cannot ignore arguments raised by a competitor just on
    the basis of widespread support for the settlement, FERC “is
    clearly entitled to give weight to the support of customers
    when deciding whether to approve a settlement offer.”
    NorAm, 
    148 F.3d at 1165
    . In its order approving the
    settlement in this case, FERC has addressed each argument
    raised by NRG, and has not relied solely on the fact that the
    settlement was “freely negotiated” to determine that the
    31
    settlement was just and reasonable. Thus, FERC’s mention of
    the fact that the settlement was freely negotiated does not
    render its decision unreasonable.
    Finally, NRG’s request for rehearing asserted that
    FERC’s determination that the JOA protocol was needed to
    ensure reliability contradicts FERC’s earlier orders in the
    underlying litigation, in which FERC explained that ConEd’s
    dependence on the 1000 MW flows across the New York City
    feeders was “more an economic consideration than a
    reliability consideration.” See Consolidated Edison Co. of
    New York, Inc. v. Public Service Electric & Gas Co., 
    120 FERC ¶ 61,161
    , 61,702 (2007). NRG maintained that even if
    FERC had changed its position on whether economic or
    reliability benefits underlay its decision to approve the order,
    the evidentiary record was based on conjecture by ConEd’s
    experts and unsupported by objective engineering data.
    Moreover, NRG contended that FERC failed to weigh the
    conflicting evidence offered by NRG’s expert, who stated that
    the settlement would decrease reliability.
    FERC, in its order denying rehearing, explained that the
    previous orders were consistent with FERC’s order approving
    the settlement because FERC’s statements on economics
    versus reliability were, in proper context, responding to
    ConEd’s arguments in the underlying litigation. 135 FERC at
    61,064. FERC also explained that “economics and reliability
    are not mutually exclusive,” and that the record upon which
    FERC approved the settlement included statements from the
    New York Commission and the City of New York explaining
    that the agreements provided critical reliability benefits. 
    Id.
    Even excluding reliability, FERC had several reasons for
    approving the settlement that would have been sufficient even
    absent reliability concerns. See 
    id.
    32
    In its petition for review, NRG essentially restates the
    arguments from its request for rehearing on the reliability
    issue.     We conclude, however, that FERC adequately
    addressed NRG’s challenge to its consideration of reliability.
    Although NRG claims that FERC attempts to “obfuscate the
    [reliability] issue by stating that ‘economics and reliability are
    not mutually exclusive,’” Pet’r Br. at 51, FERC has, in the
    very order NRG cited in its attempt to create inconsistency,
    considered both factors together. See 120 FERC at 61,701
    (“The Commission stated that while reliability was one of the
    purposes of the two contracts, economic considerations were
    more important . . . .”). The issue on which FERC denied
    rehearing in that order was whether it “correctly gave the
    proper weight to reliability considerations”; not to whether
    FERC could consider reliability at all. 
    Id. at 61,702
    .
    Moreover, we agree with FERC’s statement in rehearing that
    it had other reasons that were sufficient to approve the
    settlement apart from reliability considerations. See 135
    FERC at 61,064 (“The order addresses the important issues
    regarding the right to roll-over firm agreements, the need for
    the non-conforming JOA Protocol to do so, the fact that this
    exchange agreement reduced the need for additional
    transmission construction, and the lower prices produced in
    88 percent of the hours. These rationales would be sufficient
    to permit a rollover regardless of any reliability benefits.”).
    We therefore conclude that FERC’s discussion of reliability
    benefits does not render its order arbitrary or capricious, or
    otherwise provide a basis for granting NRG’s petition.
    III.   CONCLUSION
    For the foregoing reasons, we hold that FERC’s approval
    of the contested settlement and denial of NRG’s request for
    rehearing was based on substantial evidence and was neither
    33
    arbitrary nor capricious.   Accordingly, NRG’s petition for
    review is denied.
    So ordered.
