    The exhaustion requirements of the Federal Power Act (“FPA”)
    deprive us of jurisdiction over the Association’s petition to
    review the Tariff Order. Accordingly, we dismiss the petition
    in Case No. 16-1023 seeking review of the Tariff Order. We
    reach the merits in the Association’s challenge to the Complaint
    Order and hold that the Commission was not arbitrary or
    capricious in denying the Association’s complaint. We
    therefore deny the petition in Case No. 16-1024 seeking review
    of the Complaint Order.
    I.
    A.
    ISO New England Inc. is a private, non-profit entity that
    administers wholesale electricity and capacity markets in New
    3
    England. See Blumenthal v. FERC, 
    552 F.3d 875
    , 878 (D.C.
    Cir. 2009). In this role, ISO New England must submit its tariff
    to the Commission for approval under FPA § 205, 16 U.S.C.
    § 824d. See Braintree Elec. Light Dep’t v. FERC, 
    550 F.3d 6
    ,
    9 (D.C. Cir. 2008). The tariff establishes rates for the electricity
    and capacity markets, and FPA § 205 requires that these rates be
    “just and reasonable.” See id.
    ISO New England operates two distinct markets for
    wholesale electricity under its tariff: a day-ahead market and a
    real-time market. In the day-ahead market, participants offer to
    sell one-hour blocks of electricity to be delivered the next day.
    In the real-time market, electricity is offered in five-minute
    increments for immediate delivery, which corrects for
    imbalances between electricity scheduled in the day-ahead
    market and real-time demand. Our opinion in Black Oak
    Energy, LLC v. FERC, 
    725 F.3d 230
    , 233 (D.C. Cir. 2013),
    discusses the history and purpose of these markets.
    To ensure that generators produce enough energy in real
    time, ISO New England’s tariff includes a special pricing
    mechanism triggered when energy in the real-time market is
    scarce. When insufficient energy is being produced or energy
    prices become excessive, the price in the real-time market is set
    based upon Reserve Constraint Penalty Factors. See Complaint
    Order, at P 6. We will refer to these as “Scarcity Rates” to
    reflect their function. The Scarcity Rates are a set of fixed
    values, preestablished in ISO New England’s tariff, that
    correspond to different categories of energy generation. The
    Scarcity Rates serve as inputs to ISO New England’s pricing
    algorithm during scarcity conditions, as well as price caps
    representing maximum allowable prices in the real-time market.
    For our purposes, it is enough to say that higher Scarcity Rates
    produce higher real-time energy prices under stressed market
    conditions.
    4
    ISO New England also administers an auction market for
    capacity. Capacity is “a kind of options contract” to ensure
    availability of electricity in the future. Advanced Energy Mgmt.
    All. v. FERC, 
    860 F.3d 656
    , 659 (D.C. Cir. 2017) (per curiam).
    Under ISO New England’s tariff, capacity is allocated in a
    forward capacity market in which capacity is bought and sold in
    annual blocks three years in advance. See Complaint Order, at
    P 2. For example, a capacity auction was held in February 2014
    covering the capacity commitment year of June 1, 2017, through
    May 31, 2018. Payments for capacity purchased in these annual
    auctions are delivered to capacity suppliers monthly during the
    capacity commitment year. See 
    id.
     In return, capacity suppliers
    must offer capacity in the day-ahead and real-time electricity
    markets over the course of that year. See 
    id.
    Like the Scarcity Rates in the real-time energy market, ISO
    New England uses special pricing mechanisms in the capacity
    market to correct perceived market failures. At issue here is the
    Peak Energy Rent Adjustment (the “Adjustment”), which
    attempts to claw back some revenues earned by capacity
    suppliers when prices in the real-time energy market are very
    high. The Adjustment has two intended purposes. See
    Complaint Order, at P 3 (citing Devon Power LLC, 
    115 FERC ¶ 61,340
    , at PP 24, 29 (2006)). First, it is intended to mitigate
    the costs of price spikes to electricity purchasers. Second, it is
    intended to reduce the incentive for electricity suppliers to
    generate price spikes intentionally by withholding electricity.
    To put it simply, the Adjustment removes a rolling average of
    “peak energy rents” from suppliers’ monthly capacity payments
    and rebates this revenue back to load. See Complaint Order, at
    P 4. Each day, ISO New England calculates a “strike price,” a
    price just above the marginal cost of running the most expensive
    power generator in New England. See 
    id.
     It next calculates
    hourly peak energy rents––roughly the excess of the real-time
    electricity price over the strike price––for any hour in which the
    5
    real-time price exceeds this strike price, time periods we will
    refer to as “Adjustment Events.” See 
    id.
     ISO New England then
    derives a monthly value of peak energy rents, averages it over
    the past twelve months, and subtracts this quantity from
    suppliers’ monthly capacity payments as the total Adjustment.
    See 
    id.
    Importantly, this value is deducted from every capacity
    supplier’s monthly capacity payments, without regard to
    whether a particular supplier actually sold energy in the real-
    time market at the high price. See 
    id.
     However, according to
    the Association, the vast majority of capacity suppliers clear
    their electricity offers in the day-ahead market. They therefore
    receive the day-ahead market price, rather than the real-time
    price on which the Adjustment is based. The Commission has
    acknowledged that this is a “potential inefficiency,” Tariff
    Rehearing Order, at P 105, and, in light of other changes to New
    England power markets, has approved elimination of the
    Adjustment starting with the capacity commitment year
    beginning June 1, 2019, ISO New Eng. Inc., 
    151 FERC ¶ 61,096
    ,
    at P 1 (2015).
    At issue here is the interaction between the Scarcity Rates
    and the Adjustment. Although the triggers for implementing
    Scarcity Rates and Adjustment Events are not identical, the
    magnitude of the Adjustment is based on the price of real-time
    energy, which in turn is based on the Scarcity Rates under
    certain market conditions. Thus, a change in the Scarcity Rates
    changes the Adjustment in theory, if not also in practice.
    B.
    In January 2014, ISO New England and the New England
    Power Pool (“NEPOOL”) Participants Committee submitted
    proposals to revise ISO New England’s tariff under FPA § 205,
    6
    16 U.S.C. § 824d. These proposals purported to improve
    generator performance and reliability in New England. In its
    May 2014 Tariff Order, the Commission rejected both proposals
    and instituted a proceeding under FPA § 206, 16 U.S.C. § 824e,
    to determine new rates. Tariff Order, at P 1.
    Pursuant to FPA § 206, the Commission found the existing
    tariff to be unjust and unreasonable, found each of the two
    proposed revisions had not been shown to be just and
    reasonable, and adopted a combination of the ISO New England
    and NEPOOL proposals as just and reasonable. Tariff Order, at
    PP 23–25. The Commission ordered ISO New England to
    submit a compliance filing modifying its tariff accordingly. Id.
    at P 25. Relevant here, the Commission directed increases in the
    size of a subset of the Scarcity Rates to incentivize better
    performance, as originally proposed by NEPOOL. Id. at
    PP 107–09. In light of these increases, the Commission
    instructed ISO New England to discuss in its compliance filing
    what further changes to its tariff, if any, were necessary. Id. at
    P 110. Additionally, the Commission dismissed as “beyond the
    scope of this proceeding” GDF SUEZ Energy Marketing NA,
    Inc.’s (“GDF SUEZ”) concern that increases to the Scarcity
    Rates would exacerbate inefficiencies associated with the
    Adjustment. Id. In its compliance filing, ISO New England
    ultimately agreed with this assessment, and it opted instead to
    initiate a separate stakeholder process to reconsider the
    Adjustment.
    After the Commission issued the Tariff Order, several
    parties sought rehearing or requested clarification. Two of these
    filings matter in this case. First, the Association filed a Motion
    for Clarification, which addressed an unrelated issue, but it
    never requested rehearing. See Reply Br. of Pet’r 1; Oral Arg.
    at 7:21–7:57. Second, several parties (“Indicated Generators”),
    including members of the Association, requested rehearing.
    7
    This request urged that ISO New England’s tariff exclude the
    increases to the Scarcity Rates or alter the Adjustment in light of
    the increased Scarcity Rates. JA 269–70. On November 19,
    2015, the Commission denied rehearing. Tariff Rehearing
    Order, at P 105. The Commission again recognized the
    “potential inefficiency” with the Adjustment but stated that it
    “exists independent of the increase” to the Scarcity Rates and
    was therefore unnecessary to consider in the proceeding before
    it. Id. The Commission noted that it had approved revisions to
    the tariff that eliminated the Adjustment beginning June 1, 2019,
    and suggested that any changes prior to that date could be made
    through a separate stakeholder process. Id. at P 106. As a
    result, the increased Scarcity Rates went into effect on
    December 3, 2014. See ISO New Eng. Inc., 
    149 FERC ¶ 61,009
    ,
    at P 23 (2014).
    That same day, the Association filed a complaint under FPA
    § 206 challenging the Adjustment in effect through May 31,
    2018. The Association contended that the increased Scarcity
    Rates exacerbated the adverse impact of the Adjustment, that
    capacity suppliers could not adjust their prices to adapt because
    the relevant capacity auctions––which take place three years in
    advance––had already occurred, and that the Adjustment was
    therefore unjust and unreasonable. As evidence, the Association
    referred to an analysis by ISO New England, a simulated
    historical back-cast that calculated the size of the Adjustment as
    if the new Scarcity Rates had already been in effect. The
    Association later supplemented this with data from an
    Adjustment Event that occurred on December 4, 2014. On
    January 30, 2015, the Commission denied the complaint, finding
    the Association had not met its FPA § 206 burden to show that
    ISO New England’s existing tariff––by that point, the revised
    tariff with the higher Scarcity Rates––was unjust and
    unreasonable. Complaint Order, at P 35. The Association
    8
    requested rehearing, which the Commission denied. Complaint
    Rehearing Order, at P 20. This petition for review followed.
    II.
    A.
    As a threshold matter, we lack jurisdiction to consider the
    Association’s challenge to the Tariff Order because the
    Association has not met the requirements of FPA § 313(a), 16
    U.S.C. § 825l(a). This provision is a “mandatory petition-for-
    rehearing requirement.” Granholm ex rel. Mich. Dep’t of Nat.
    Res. v. FERC, 
    180 F.3d 278
    , 281 (D.C. Cir. 1999). We have no
    “discretion to ignore this ‘express statutory limitation on the
    jurisdiction of the court.’” DTE Energy Co. v. FERC, 
    394 F.3d 954
    , 960 (D.C. Cir. 2005) (quoting Cal. Dep’t of Water Res. v.
    FERC, 
    306 F.3d 1121
    , 1125 (D.C. Cir. 2002)). Although FPA
    § 313(a) was not briefed, “we have an independent obligation to
    assure ourselves of jurisdiction, even where the parties fail to
    challenge it.” Floyd v. District of Columbia, 
    129 F.3d 152
    , 155
    (D.C. Cir. 1997).
    Section 313(a) states: “No proceeding to review any order
    of the Commission shall be brought by any entity unless such
    entity shall have made application to the Commission for a
    rehearing thereon.” 16 U.S.C. § 825l(a) (emphasis added).
    While the Association filed a Motion for Clarification of the
    Tariff Order, it did not file an “application to the Commission
    for a rehearing thereon,” so we cannot consider its petition to
    review that order.
    Moreover, it is insufficient under § 313(a) that the Indicated
    Generators, which requested rehearing, may include members of
    the Association. Section 313(a) governs our ability to entertain
    a petition to review a Commission order “by any entity.” We
    9
    lack jurisdiction to do so unless “such entity”––that is, the entity
    petitioning our court for review––requested rehearing. There is
    no contention here that Indicated Generators and the Association
    are the same “entity,” even if some members overlap. Thus, the
    Association needed to seek rehearing. It did not. While we
    need not consider precisely why Congress created this unusually
    demanding exhaustion scheme, cf. ASARCO, Inc. v. FERC, 
    777 F.2d 764
    , 774 (D.C. Cir. 1985) (considering rationale behind
    materially equivalent rehearing requirement in the Natural Gas
    Act), our precedent is clear that § 313(a) deprives us of
    jurisdiction over the claims of a petitioner who failed to seek
    rehearing, even if some other party sought rehearing, see, e.g.,
    DTE Energy, 
    394 F.3d at
    960–61.
    B.
    Even if the Association had submitted its Motion for
    Clarification as a request for rehearing, which it did not, we
    would still lack jurisdiction over the Tariff Order for another
    reason. Section 313(b) of the FPA provides, “No objection to
    the order of the Commission shall be considered by the 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.” 16 U.S.C. § 825l(b)
    (emphases added). Like § 313(a), this prerequisite for review is
    jurisdictional; we have no discretion to disregard it. See DTE
    Energy, 
    394 F.3d at 961
    . That is, under § 313(b), the party
    seeking judicial review must have raised in its rehearing request
    before the Commission each objection it puts before the
    reviewing court. See Platte River Whooping Crane Critical
    Habitat Maint. Tr. v. FERC, 
    876 F.2d 109
    , 112–13 (D.C. Cir.
    1989); see also Kelley ex rel. Mich. Dep’t of Nat. Res. v. FERC,
    
    96 F.3d 1482
    , 1487–88 (D.C. Cir. 1996) (rejecting “implicit”
    arguments as insufficient). Here, the Association’s Motion for
    Clarification concerned an issue distinct from those now
    10
    advanced in its petition for judicial review. The Association
    thus failed to meet the requirement of § 313(b).
    Nor can the contents of Indicated Generators’ rehearing
    request save the Association. It is of no moment that Indicated
    Generators objected to the increased Scarcity Rates’ effect on
    the Adjustment. Like § 313(a), § 313(b) contains an identity of
    entity exhaustion requirement. It is not enough that some party
    before the Commission raised the argument and that the
    Commission considered it; instead, the party petitioning for
    judicial review must itself have requested rehearing, and made
    the same objections it seeks to raise in court. See Platte River,
    
    876 F.2d at
    112–13. The text of § 313(b) “makes it plain that
    what is referred to is the same application for rehearing
    mentioned earlier in subsection (b), which in turn (by reason of
    the same use of the definite article) clearly refers to the same
    application for rehearing mentioned in subsection (a), to wit, the
    application of the party who seeks judicial review.” ASARCO,
    
    777 F.2d at 773
     (discussing materially equivalent language in
    the Natural Gas Act).
    The Association offers the excuses that it had a “reasonable
    ground for failure,” 16 U.S.C. § 825l(b), to raise its objections
    in a rehearing petition, and that the Tariff and Complaint Orders
    are so “inextricably linked” that they must be considered
    together, Reply Br. of Pet’r 4. The “reasonable ground”
    exception “is reserved for an ‘extraordinary situation,’” such as
    when a Commission practice is admitted or adjudged to be
    unlawful. Save Our Sebasticook v. FERC, 
    431 F.3d 379
    , 382
    (D.C. Cir. 2005) (quoting Wis. Power & Light Co. v. FERC, 
    363 F.3d 453
    , 460 (D.C. Cir. 2004)). The Association’s alleged
    “reasonable ground”––that it “reasonably believed” the
    Adjustment would be addressed in ISO New England’s
    compliance filing, Reply Br. of Pet’r 2––is not comparable to
    the “reasonable grounds” we have previously accepted. In any
    11
    event, the Association’s position is unconvincing in light of
    previous decisions in this proceeding: ISO New England
    stakeholders had already rejected GDF SUEZ’s proposal to
    modify the Adjustment, see JA 154, and the Commission, in
    directing ISO New England’s compliance filing, explicitly gave
    ISO New England the option not to further alter its tariff in
    response to the increased Scarcity Rates, see Tariff Order, at
    P 110. The Association was certainly on notice that the
    Adjustment might not be changed––Indicated Generators
    evidently saw the problem and petitioned for rehearing
    accordingly––so this by no means presents an extraordinary
    situation.
    In addition, the two cases the Association cites for its
    “inextricable link” argument, Reply Br. of Pet’r 4, do not control
    on our facts. The cited language from Cities of Batavia v.
    FERC, 
    672 F.2d 64
    , 72 n.15 (D.C. Cir. 1982), is dicta from a
    footnote; the jurisdictional issue there was resolved on other
    grounds, 
    id.
     at 72–73. Kansas Cities v. FERC, 
    723 F.2d 82
    (D.C. Cir. 1983), found jurisdiction when a rehearing request
    timely challenged an order accepting a compliance filing but not
    an earlier order specifying the relevant legal rule to be used in
    the agency proceedings, 
    id.
     at 85–86. In that case, it was unclear
    whether the petitioners were “aggrieved” by the earlier order, as
    is required for jurisdiction under FPA § 313. See Kan. Cities,
    
    723 F.2d at
    85–86 & n.3. Here, we need not consider when the
    Association became “aggrieved” because the Association never
    filed a rehearing request. Furthermore, unlike both Cities of
    Batavia and Kansas Cities, the jurisdictional problem in our case
    does not concern the fact that there were multiple Commission
    orders in the same ongoing proceeding. Distinct from the Tariff
    Orders, the Complaint Orders are from a wholly separate,
    Association-initiated proceeding, albeit concerning related
    content. Applying the exception to the Association’s petition
    would render § 313(b)’s strict jurisdictional bar toothless for
    12
    Commission-initiated § 206 proceedings, as any complaint
    would be “inextricably linked” to the earlier agency
    proceedings.
    III.
    A.
    Although we have no jurisdiction to consider the
    Association’s objections to the Tariff Order, we have
    jurisdiction to consider its objections to the Complaint Order.
    The Association filed a timely request for rehearing raising the
    objections it now presses in its timely petition for judicial
    review. The Association has therefore satisfied FPA § 313’s
    jurisdictional requirements. See 16 U.S.C. § 825l(a), (b); 
    18 C.F.R. §§ 385.713
    (b), 385.2007(a).
    The FPA dictates the standard of judicial review. In a
    proceeding under FPA § 205, such as the initial proposed tariff
    revisions by ISO New England and NEPOOL, “[t]he utility
    bears ‘the burden of proof to show that the increased rate . . . is
    just and reasonable . . ..’” Advanced Energy Mgmt., 860 F.3d at
    662 (quoting 16 U.S.C. § 824d(e)). In a proceeding under FPA
    § 206, such as the Association-initiated complaint proceeding,
    the challenging party, whether the Commission or a
    complainant, carries the burden of proving a rate is unjust and
    unreasonable. See 16 U.S.C. § 824e(b); see also, e.g., La. Pub.
    Serv. Comm’n v. FERC, 
    860 F.3d 691
    , 695 (D.C. Cir. 2017).
    Once the Commission finds that a rate is unjust and
    unreasonable, the Commission bears the burden of determining
    a new just and reasonable rate. See Advanced Energy Mgmt.,
    860 F.3d at 663 (citing 16 U.S.C. § 824e(a)). We review
    Commission determinations under the arbitrary and capricious
    standard. See Blumenthal, 
    552 F.3d at
    881 (citing 
    5 U.S.C. § 706
    (2)(A)). Because we are dealing here with technical and
    13
    policy-based determinations, the Commission’s judgment is
    entitled to judicial respect. See S.C. Pub. Serv. Auth. v. FERC,
    
    762 F.3d 41
    , 55 (D.C. Cir. 2014) (per curiam).
    We conclude that the Complaint Orders were not arbitrary
    and capricious. The Association initiated its complaint pursuant
    to FPA § 206 and accordingly bore the burden of proof. The
    Commission confronted the Association’s evidence and found
    it insufficient to demonstrate that rates were unjust and
    unreasonable.      Complaint Order, at PP 35–41.             The
    Commission, while carefully explaining why the Association
    had failed to deal adequately with the overall revenue context,
    left open the possibility that additional evidence could alter its
    judgment. Id. at P 40. The Commission gave three reasons for
    its judgment.
    First, the Commission found that the Association’s
    evidence, which consisted of data from the December 4, 2014,
    Adjustment Event and a counterfactual historical back-cast,
    neglected to consider the likely frequency and size of future
    Adjustment Events. Complaint Order, at PP 36, 40; Complaint
    Rehearing Order, at PP 23, 28. Without such context, especially
    in light of other changes to ISO New England’s tariff, the
    Commission reasonably found that this evidence did not show
    the Adjustment was unjust and unreasonable. Contrary to the
    Association’s claim before the court, the Commission did not
    require proof of “additional instances of actual harm,” Br. for
    Pet’r 43, but rather found that the Association had failed to
    explain what its data meant for the total impact of the
    Adjustment.
    Second, the Commission faulted the Association for not
    addressing potential increases to energy prices in the day-ahead
    market, which in aggregate might offset expected increases to
    the Adjustment. Complaint Order, at PP 38–39; Complaint
    14
    Rehearing Order, at P 29. The Commission noted that these
    rates adjust daily and might, on average, increase in anticipation
    of expected higher real-time market prices due to the increased
    Scarcity Rates. Complaint Order, at PP 38–39. The
    Association’s shortcoming, in the Commission’s view, was its
    failure to consider how other aspects of the energy market might
    respond to the new Scarcity Rates. As such, the Commission
    reasonably explained why it thought the Association had not
    demonstrated an aggregate change to supplier revenue that was
    unjust and unreasonable.
    Third, the Commission determined that price floors
    effective in pre-Tariff Order capacity auctions might
    compensate for any additional losses from the potentially larger
    Adjustment. Id. at P 37. The Association takes issue with this
    because the price floors were already part of the just and
    reasonable rate on file, so, the Association contends, the price
    floors cannot offset a change to the Adjustment. Br. for Pet’r
    37–42. This is not strictly correct, as “[t]he Supreme Court has
    repeatedly rejected the argument that there is only one just and
    reasonable rate possible . . ..” Blumenthal, 
    552 F.3d at 883
    (internal quotation marks omitted). To the extent the price
    floors generated rates high in the “zone of reasonableness,” cf.
    Maine v. FERC, 
    854 F.3d 9
    , 22–24 (D.C. Cir. 2017) (clarifying
    role of “zone of reasonableness” in FPA § 206 proceedings),
    they might prevent increases to the Scarcity Rates from making
    the Adjustment unjust and unreasonable. Regardless, in denying
    rehearing, the Commission did not rely on its price-floor
    determination, except insofar as it argued that settled
    expectations do not preclude rate changes. Complaint
    Rehearing Order, at P 30 & n.46.
    Because the Commission fulfilled its obligation to “examine
    the relevant data and articulate a satisfactory explanation for its
    action,” Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins.
    15
    Co., 
    463 U.S. 29
    , 43 (1983), we find the Complaint Orders were
    not arbitrary or capricious.
    B.
    We decline to disturb this result––as the Association urges
    us to do––in response to the outcome of the Association’s
    second complaint proceeding challenging the Adjustment under
    FPA § 206, initiated in September 2016. See New Eng. Power
    Generators Ass’n v. ISO New Eng., Inc., 
    158 FERC ¶ 61,034
    , at
    P 13 (2017). In that proceeding, the Association provided
    twenty months of additional evidence in arguing that the
    Adjustment had become unjust and unreasonable because of the
    increased Scarcity Rates. See 
    id.
     at PP 13–23 (summarizing the
    complaint). The Commission agreed. 
    Id.
     at P 48.1 This
    additional evidence cured the Commission’s concern that the
    limited evidence initially relied upon might not reflect overall
    market conditions under the revised tariff. 
    Id.
     at PP 49–51.
    So long as any change is reasonably explained, it is not
    arbitrary and capricious for an agency to change its mind in light
    of experience, or in the face of new or additional evidence, or
    further analysis or other factors indicating that the agency’s
    earlier decision should be altered or abandoned. Cf. FCC v. Fox
    Television Stations, Inc., 
    556 U.S. 502
    , 514–16 (2009). The
    Supreme Court has itself overruled many of its decisions over
    the years in light of such considerations. See Congressional
    Research Service, The Constitution of the United States of
    America: Analysis and Interpretation, S. Doc. No. 112-9, at
    1
    As of this opinion, an uncontested settlement is pending
    before the Commission. We note that any settlement would not fully
    moot this case because the second complaint proceeding has a refund
    effective date of September 30, 2016, see New Eng. Power Generators
    Ass’n, 
    158 FERC ¶ 61,034
    , at P 1, whereas the complaint in this case
    requested a refund effective date of December 3, 2014, see JA 378.
    16
    2623–35 (2017). As a corollary, a change in an agency’s course
    in reaction to new information does not indicate that its initial
    course was necessarily arbitrary and capricious when charted.
    On the facts before us, the Commission’s reconsideration when
    presented with more data does not change our view of the
    propriety of the Complaint Orders.
    IV.
    The Association also raises procedural objections to the
    Commission’s orders, arguing that the Commission unlawfully
    allocated burdens of proof and imposed illegal evidentiary rules.
    As a preliminary matter, the Association, in its rehearing
    request, did not raise the argument that the Commission
    improperly shifted the burden of proving that the Adjustment
    was unjust and unreasonable.2 This objection is therefore barred
    under FPA § 313(b) for reasons already discussed. The
    Association’s objections are in any event not well-taken. The
    Commission complied with the burdens of proof of the FPA.
    And the Association’s evidentiary challenges amount to little
    more than complaints about the Commission’s weighing of
    evidence, which we have already concluded the Commission
    carried out in a satisfactory manner in accordance with the
    burdens of proof.
    V.
    For the reasons stated above, the petition for review of the
    Tariff Order, Case No. 16-1023, is dismissed for lack of
    2
    The Association did raise an argument about who bears the
    burden of proving a new rate is just and reasonable once an existing
    rate is found to be unjust and unreasonable under FPA § 206.
    However, this is distinct from the argument now raised before this
    court.
    17
    jurisdiction and the petition for review of the Complaint Order,
    Case No. 16-1024, is denied on the merits.
    So ordered.
