    OPINION
    BERZON, Circuit Judge:
    A.   Introduction
    At their origins during the New Deal, the Bonneville Proj-
    ect’s hydroelectric operations in the Pacific Northwest,
    administered by the Bonneville Power Administration
    (“BPA”), were promoted as spreading the benefits of afford-
    able federal power widely, to “the farmer and the factory, and
    16522          PACIFIC NORTHWEST GENERATING v. DOE
    all of you and me.”2 At the same time, the Project gave a vital
    boost to the aluminum industry of the Pacific Northwest.
    Indeed, in the early days of the Project, what was good for
    BPA was good for the aluminum industry, and what was good
    for the aluminum industry was good for BPA. Aluminum
    manufacturers received low-cost federal hydroelectric power
    to operate energy-intensive smelting operations in the Pacific
    Northwest, and BPA gained a reliable market for a supply of
    electric power that otherwise greatly exceeded demand in a
    region where rural electrification was still a work in progress.
    See H.R. Rep. No. 96-976, pt. 2, at 27 (1980), as reprinted in
    1980 U.S.C.C.A.N. 6023.
    BPA’s synergistic relations with the aluminum industry
    during this early period were widely seen as a public good.
    The aluminum manufacturers and the region’s nascent avia-
    tion industry, which they supplied, not only brought many
    high-wage jobs to the Pacific Northwest, but also served as a
    vital strategic asset for the United States during World War II
    and the Cold War decades that followed.3
    Times have changed. Public utilities and electrical coopera-
    tives serve a larger regional population with greater needs for
    electrical power, see id., to which they are statutorily guaran-
    teed preferential access. See 16 U.S.C. § 832c(a).4 Rising

    energy prices have made the relatively inexpensive federal
    power generated by BPA more attractive than ever, not only
    to BPA’s regional “ ‘preference’ customers,” Aluminum Co.
    of America v. Central Lincoln Peoples’ Util. Dist. (“Alcoa”),
    
    467 U.S. 380
    , 384 (1984), but also to utilities outside the
    Pacific Northwest.5
    At the same time, due to a variety of factors — among
    them higher energy costs — the region’s aluminum industry
    has fallen on hard times. The smelting operations of the major
    aluminum manufacturers, which traditionally ran on electric
    power purchased directly from BPA, are generally being
    operated at reduced capacity, and in some cases, have shut
    down entirely. This case centers on how much BPA can or
    must do, under the authority and mandate conferred upon it
    by Congress, to aid its longtime, but now ailing, customers.
    The assistance largely at issue here consists of three three-
    party contracts BPA executed in June 2006, each with a local
    public utility company and one of the aluminum companies
    that are “direct service industrial” customers (“DSIs”) of
    BPA. In the contracts, BPA committed itself to make pay-
    ments to the aluminum company DSIs (“aluminum DSIs”)
    totaling a maximum of $59 million per year for five years in
    lieu of supplying them with actual electrical power, while
    retaining the option to sell them physical power instead in the
    final two years. In addition, in September 2006, BPA
    arranged for the sale of physical power to Port Townsend
    Paper Company (“Port Townsend”), the sole existing DSI that
    is not an aluminum manufacturer, via a contract between BPA
    and a local utility company, Public Utility District Number 1
    of Clallam County (“Clallam”), for the sale of physical
    5
    Numerous opinions of this Court “chronicle the history of BPA and
    describe the tangle of statutes that govern its operations.” Golden Nw. Alu-

    , 1041 (9th Cir. 2007) (citing cases).
    Accordingly, we confine our discussion to the particular facts relevant to
    this appeal.
    16524        PACIFIC NORTHWEST GENERATING v. DOE
    power, which Clallam would then supply to Port Townsend.
    Challenges to these four contracts by aluminum DSI Alcoa;
    the Pacific Northwest Generating Cooperative, an organiza-
    tion of electrical cooperatives that are preference customers of
    BPA (collectively, “Cooperative”); and Industrial Customers
    of Northwest Utilities, an organization of firms which pur-
    chase electricity from utility companies, rather than directly
    from BPA (collectively, “Industrial Customers”), form the
    basis of the seven petitions that have been consolidated in this
    case. Both Port Townsend and the Public Power Council, an
    association of consumer-owned utilities, have intervened as
    interested parties.
    B.   The Statutory Context
    To set out the complex statutory landscape against which
    we consider these challenges, we briefly review the enact-
    ments in which Congress over the past seven decades has
    established and regulated BPA’s authority to sell the output of
    the Federal Columbia River Power System, as the regional
    energy generation operations which began with the Bonne-
    ville Project are known. See Golden Nw. Aluminum, 
    501 F.3d at 1041
    .
    The Bonneville Project Act of 1937 (“Project Act”), 
    16 U.S.C. § 832
    -832j, created BPA as the authority responsible
    for the “sale and disposition” of the electric energy generated
    by the federal hydroelectric projects in the Pacific Northwest.
    See § 832a. The Project Act directed that “in disposing of
    electric energy generated at [the Bonneville] project, [BPA
    shall at all times] give preference and priority to public bodies
    and cooperatives.” § 832c(a). At the same time, the Project
    Act also authorized BPA, subject to this preference and prior-
    ity restriction, to enter into contracts for the “sale at wholesale
    of electric energy . . . to private agencies and persons.”
    § 832d(a). Historically, there have been two types of private
    entities that purchase electric power directly from BPA:
    investor-owned utility companies (“IOUs”) and DSIs. See
    PACIFIC NORTHWEST GENERATING v. DOE                 16525
    Ass’n of Pub. Agency Customers, Inc. v. BPA, 
    126 F.3d 1158
    ,
    1164 (9th Cir. 1997).
    Over the following decades, Congress responded to
    increasing demand for BPA’s low-cost federal power within
    and outside the Pacific Northwest with four additional pieces
    of legislation relevant to this case:
    First, in 1964, Congress passed the Regional Preference
    Act, 
    16 U.S.C. §§ 837
    -837h (“RPA”), which provides that the
    sale of electric energy from “Federal hydroelectric plants in
    the Pacific Northwest” to customers outside the region must
    be limited to “surplus energy,” § 837a, defined as “energy . . .
    which would otherwise be wasted because of the lack of a
    market therefor in the Pacific Northwest at any established
    rate.” § 837(c).6
    Second, the Transmission Act, 
    16 U.S.C. §§ 838
    -838h,
    enacted in 1974, established the basic principles that rates for
    BPA power must
    be fixed and established (1) with a view to encourag-
    ing the widest possible diversified use of electric
    power at the lowest possible rates to consumers con-
    sistent with sound business principles, (2) having
    regard to the recovery . . . of the cost of producing
    and transmitting such electric power, . . . and (3) at
    levels to produce such additional revenues as may be
    required, in the aggregate with all other revenues of
    the Administrator, to pay when due [expenses related
    to] . . . all bonds issued and outstanding pursuant to
    this chapter . . . .
    § 838g.
    6
    The current definition of “surplus energy” reads “electric energy for
    which there is no market in the Pacific Northwest at any rate established
    for the disposition of such energy.” See § 839f(c).
    16526         PACIFIC NORTHWEST GENERATING v. DOE
    Third, the Northwest Power Act, 
    16 U.S.C. §§ 839
    -839h
    (“NWPA”), signed into law in 1980, was triggered by Con-
    gress’s recognition that demand within the Pacific Northwest
    for low-cost federal power threatened to outstrip supply, and
    that BPA’s dams were having a significant impact on the
    region’s fish and wildlife. See Ass’n of Pub. Agency Custom-
    ers, 
    126 F.3d at 1165
    . The NWPA contains several provisions
    central to this litigation.
    Initially, the NWPA directs that “[w]henever requested,”
    by either a “public body and cooperative entitled to prefer-
    ence under the [Project Act]” or an “investor-owned utility,”
    BPA “shall offer to sell . . . electric power to meet the
    [requesting entity’s] firm power load.”7 § 839c(b)(1). In the
    same section of the Act, Congress also states that BPA is “au-
    thorized to sell in accordance with this subsection electric
    power to existing [DSI] customers.” § 839c(d)(1)(A). The
    statute then instructs BPA to offer “an initial long term con-
    tract” for the sale of electric power to each of its existing DSI
    customers, § 839c(d)(1)(B), and, under a separate subsection,
    to its public utility and cooperative customers and IOUs.
    § 839c(g). The NWPA also authorizes BPA, in § 839c(f), to
    “sell, or otherwise dispose of, electric power, including power
    acquired pursuant to this and other Acts, that is surplus to
    [BPA’s] obligations incurred pursuant to subsections (b), (c),
    and (d) of this section[,] in accordance with this and other
    Acts applicable to [BPA] . . . .”
    In addition, the NWPA directs BPA to “establish, and peri-
    odically review and revise, rates for the sale and disposition
    of electric energy,” § 839e(a)(1), which are subject to “confir-
    mation and approval by the Federal Energy Regulatory Com-
    mission [(“FERC”)] upon a finding by the Commission” that,
    7
    “Firm power” is power or power capacity that an electric utility prom-
    ises to deliver to a customer on a non-interruptible basis. “Firm power
    load” is the total amount of “firm power” that a utility has committed to
    providing its customers.
    PACIFIC NORTHWEST GENERATING v. DOE            16527
    among other things, “such rates . . . are based upon [BPA]’s
    total system costs.” § 839e(a)(2)(B). Rates for preference cus-
    tomers are mandated, accordingly, to be sufficient to “recover
    the costs of that portion of the Federal base system resources
    needed to supply such loads,” § 839e(b)(1), with “Federal
    base system resources” defined as
    (A) the Federal Columbia River Power System
    hydroelectric projects;
    (B) resources acquired by [BPA] in longterm con-
    tracts . . . ; and
    (C) resources acquired by [BPA] in an amount
    necessary to replace reductions in capability of the
    resources referred to in subparagraphs (A) and (B) of
    this paragraph.
    § 839a(10). Congress also instructed that “rates applicable to
    direct service industrial customers shall be established,”
    § 839e(c)(1), at a level that is “based upon [BPA’s] applicable
    wholesale rates to [preference] customers and the typical mar-
    gins included by such [preference] customers in their retail
    industrial rates [plus other considerations] . . . .” § 839e(c)(2).
    C.   The Present Litigation
    The events that immediately gave rise to this litigation
    began in June 2005, when BPA initiated the process that
    resulted in the execution of the contracts challenged here. On
    June 30, 2005, BPA issued a Record of Decision on Service
    to Direct Service Industrial (DSI) Customers for Fiscal Years
    2007-2011 (“DSI Service ROD”), in which it announced its
    intention to enter into the three-way contracts with the alumi-
    num DSIs and the local utility companies. The proposed con-
    tracts would provide “service benefits,” with the default form
    of delivery of the benefits being “financial payment[s]” by
    BPA to the DSIs. BPA retained a one-way option, however,
    16528         PACIFIC NORTHWEST GENERATING v. DOE
    in the fourth and fifth years of each of the contracts to discon-
    tinue a portion of the payments to a particular DSI and supply
    that DSI with physical power instead, although the DSI could
    then elect to refuse service and terminate the agreement. BPA
    specified that before exercising that option, the agency would
    conduct a “public process” to consider and explain its deci-
    sion.
    The amount of the payments to the DSIs was determined
    according to a formula based on the difference between the
    market price of power and BPA’s standard rate for power sold
    to its preference customers (“PF rate”). Under the default
    mode, monetary payments to each DSI would be made in an
    amount equal to this price differential multiplied by the
    amount of physical power the DSI purchased from the local
    utility partner, thus tying the value of the benefit to the DSI’s
    electricity use and, therefore, to its level of operations and
    employment.8
    Crucially, BPA placed three limitations on the amount of
    the payments it would make to the DSIs each year. First, BPA
    obligated itself to make the payments only on the first 560
    average megawatts (“aMW”)9 of capacity consumed by the
    DSIs each year.10 Second, BPA capped the price differential
    it was willing to pay the DSIs for the power they purchased
    on the open market at no more than $24/MWh. Third, BPA
    8
    Under the alternative mode, BPA would supply physical power to the
    local utility for sale to the DSI at a price to be determined by BPA, but
    no lower than the PF rate.
    9
    aMW is a measure of capacity. Power is typically priced by megawatt
    hours (MWh), a measure of usage, where 1 MWh = 1 hour of use × 1
    aMW. Thus, 560 aMW, if used continuously for a year, will equate to
    4,905,600 MWh of power usage (560 aMW × 24 hours/day × 365 days/
    year).
    10
    Of the 560 aMW, BPA allocated 100 aMW to GNA, 320 aMW to
    Alcoa, and 140 aMW to CFAC. Alcoa had requested an allocation of 438
    aMW.
    PACIFIC NORTHWEST GENERATING v. DOE                   16529
    limited the total annual benefit the DSIs could receive to $59
    million.11
    BPA acknowledged in the DSI Service ROD that “service
    to the DSIs will come at the expense of higher rates paid by
    . . . preference customers.” While BPA stated that it would
    “not revisit[ ] its . . . decision to serve some amount of DSI
    load at a known and capped cost,” it also indicated — in
    apparent contradiction — that both the decision to contract
    with the DSIs and the level of service benefits that it would
    provide were possibly subject to change. Alcoa and the Coop-
    erative both filed in this Court timely petitions for review of
    the DSI Service ROD.
    On May 31, 2006, BPA issued a Supplement to the DSI
    11
    The following three simplified hypotheticals illustrate the general con-
    tours of the monetary benefit plan and the effect of each of the limitations.
    Hypothetical 1: Assume the DSIs use 700aMW of power continuously for
    a year, the average market price for power is $32/MWh in that year, and
    the rate charged to preference customers (“PF rate”) is $30/MWh. If no
    limitations were in place, the DSIs would be entitled to a monetary pay-
    ment of $12.3 million (700aMW × 24 hours/day × 365 days/year × ($32/
    MWh [Market rate] − $30/MWh [PF rate])). However, because the benefit
    extends only to the first 560aMW used by the DSIs, the actual monetary
    benefit would total only $9.8 million (560aMW × 24 hours/day × 365
    days/year × ($32/MWh − $30/MWh)).
    Hypothetical 2: Assume that the DSIs use only 200aMW of capacity con-
    tinuously for a year, but the market price of power for that year is $60/
    MWh, rather than $32/MWh. Without BPA’s limitations, the monetary
    benefit paid to the DSIs would be $52.6 million (200aMW × 24 hours/day
    × 365 days/year × ($60/MWh − 30/MWh)). The $24/MWh limitation,
    however, reduces that benefit to $42.0 million (200aMW × 24 hours/day
    × 365 days/year × $24/MWh [benefit cap]).
    Hypothetical 3: Assume the DSIs use only 560aMW of capacity continu-
    ously for a year, and the market price of power for that year is $50/MWh.
    Without BPA’s limitations, the monetary benefit owed to the DSIs would
    be $98.1 million (560 aMW × 24 hours/day × 365 days/year × ($50/Mwh
    [Market rate] − $30/MWh [PF rate])). The $59 million total annual cap
    applies, however, and limits the total payment to that amount.
    16530          PACIFIC NORTHWEST GENERATING v. DOE
    Service ROD (“Supplemental ROD”), which announced cer-
    tain revisions in the agency’s plan to contract with the DSIs.
    In particular, BPA decided to provide “slightly more operat-
    ing flexibility” to the aluminum DSIs by reducing the mini-
    mum level of energy usage required for eligibility to receive
    the monetary benefit payments.12 The plan’s main provisions,
    including the service benefit levels and the method of deliv-
    ery, remained unchanged. Alcoa and the Cooperative again
    both filed in this Court timely petitions, this time for review
    of the Supplemental ROD.
    In June 2006, less than a month after the issuance of the
    Supplemental ROD, BPA executed contracts with the three
    aluminum DSIs — Alcoa, Columbia Falls Aluminum Co. and
    Golden Northwest Aluminum Holding Co. — under the terms
    described in the Supplemental ROD. Alcoa and the Coopera-
    tive petitioned this Court for review of those contracts as well.
    In the DSI Service ROD and the Supplemental ROD, BPA
    also announced that it would provide Port Townsend with its
    full requirements for power, seventeen aMW, to be supplied
    through Clallam. Under the final proposal, the rate for power
    sold by BPA to Clallam would be set at a level equal to the
    agency’s rate for power sold to local utilities (the PF rate)
    plus the margin typically charged by the latter to their indus-
    trial customers. BPA, Clallam, and Port Townsend then exe-
    cuted contracts providing for power service to Port Townsend
    through Clallam. Industrial Customers timely filed a petition
    for review of the contracts.
    D.    BPA’s Rate Schedules
    Because a central dispute among the parties in this case
    concerns which of BPA’s various power rate schedules should
    12
    Under BPA’s initial plan, a DSI had to utilize at least 50% of its allo-
    cated capacity to be eligible for the monetary benefit. The revised proposal
    lowered this requirement to 25%.
    PACIFIC NORTHWEST GENERATING v. DOE            16531
    apply to the contracts at issue, a brief overview of the possible
    rate categories is in order.
    BPA is required by its governing statutes to “establish” a
    number of energy rate schedules for the sale of power to dif-
    ferent customer groups. See § 839e(a)(1). BPA calculates
    these rate schedules according to detailed statutory guidelines,
    see § 839e(a)-(h), and promulgates them through a formal
    ratemaking procedure that includes publication of proposed
    rates in the Federal Register, public hearings, and FERC
    approval. See § 839e(i). Four of BPA’s rate schedules are at
    issue in this case: the PF rate, the Industrial Firm Power
    (“IP”) rate, the New Resources (“NR”) rate, and the Firm
    Power Products and Services (“FPS”) rate.
    (a)   PF rate
    The PF rate is a cost-based rate at which BPA sells firm
    power to its preference customers, whose requirements for
    firm power the agency is required to fulfill. See §§ 839c(b),
    839e(b). It is calculated pursuant to guidelines specified in
    § 839(e)(b), and is BPA’s lowest published rate. For the year
    ending September 30, 2007, the average PF rate was $27.33/
    MWh.
    (b)   IP rate
    The IP rate is “applicable to [firm power sales] made to
    direct service industrial customers” and is “established” pur-
    suant to the requirements of § 839(e)(c). Like the PF rate, it
    is a cost-based rate. See § 839(e)(c). For the year ending Sep-
    tember 30, 2007, the average IP rate was $45.08/MWh.
    (c)   NR rate
    The NR rate applies to power sales to utilities that are used
    by those utilities to serve “new large single load[s].” See §
    839a(13); the NR rate is intended to penalize DSI customers
    16532         PACIFIC NORTHWEST GENERATING v. DOE
    who attempt to lower their energy costs by purchasing power
    at lower rates from one of the public utilities that BPA serves
    instead of purchasing the power directly from BPA at the IP
    rate. See H.R. Rep. No. 96-976, pt. 1, at 25, 51 (describing
    purpose of NR rate as a deterrent). For the fiscal year ending
    September 30, 2007, the average NR rate was $77.03/MWh.
    (d)    FPS rate
    The FPS rate is perhaps the most confounding of BPA’s
    rate schedules, but, because all four of the contracts at issue
    utilize it, also the most important for this case.
    As it does for the PF, IP, and NR rates, BPA establishes an
    FPS rate schedule pursuant to the ratemaking requirements of
    § 839e(i), which it then publishes. See BONNEVILLE POWER
    ADMINISTRATION, 2007 WHOLESALE POWER RATE SCHEDULES 55-
    59 (November 2006) (hereinafter “Wholesale Power Rate
    Schedule”), available at http://www.bpa.gov/power/PFR/
    rates/2007-09_Power_Rates.pdf. Unlike the other rate sched-
    ules, however, the FPS rate schedule includes a provision,
    entitled “Flexible Rate,” which states that energy rates “may
    be specified at a higher or lower average rate [than the pub-
    lished rate] as mutually agreed by BPA and the Purchaser.”
    See id. at 57. In other words, although BPA publishes an FPS
    rate schedule, BPA and the contracting customer are free to
    deviate from this published rate by mutual agreement. See
    Supplemental ROD (“Power is sold under the FPS schedules
    at rates mutually agreed to by BPA and the purchaser.”).
    Thus, a sale made pursuant to the FPS rate schedule could, in
    theory, be made at any price. As such, the FPS rate schedule
    is, in effect, no rate schedule at all.13
    13
    No party challenges BPA’s statutory authority to sell power at mutu-
    ally agreed upon rates that have not been previously approved by FERC.
    This Court therefore assumes, without deciding, that BPA has such author-
    ity.
    PACIFIC NORTHWEST GENERATING v. DOE                    16533
    II.    Jurisdiction
    The NWPA gives this Court, as the “court of appeals for
    the region,” jurisdiction to hear any suit challenging “final
    actions and decisions taken pursuant to this chapter [of the
    NWPA] by [BPA]” or to “the implementation of such final
    actions, whether brought pursuant to this chapter, the [Project]
    Act, the [Regional Preference Act], or the [Transmission]
    Act.” § 839f(e)(5). The NWPA lists certain BPA actions as
    representing “final actions subject to judicial review” under
    the Administrative Procedure Act, 
    5 U.S.C. §§ 701-06
    . See
    § 839f(e)(1)(A)-(H).14 Among the listed actions are “sales . . .
    of electric power under section 839c of this title.”
    § 839f(e)(1)(B).
    All four of the contracts at issue either involve sales of
    electric power made pursuant to BPA’s authority under
    § 839c or are, at least, “other final” agency actions under
    § 839f(e)(3), and so are reviewable by this court.15 Thus, we
    have jurisdiction to review the validity of the contracts,
    including (1) whether BPA is authorized and/or obligated to
    14
    The NWPA’s jurisdictional grant also contains a “catch-all” provision
    which makes clear that our jurisdiction to review the agency’s action is not
    confined to the listed actions. See § 839f(e)(3) (“Nothing in this section
    shall be construed to preclude judicial review of other final actions and
    decisions by the . . . Administrator.”).
    15
    The aluminum DSI contracts do not, under the monetary benefit
    option, involve the physical delivery of power. They may nonetheless
    qualify as “sales of electric power” as they are designed to effectuate the
    delivery of power to the DSIs at a rate agreed upon by the DSIs and BPA,
    by subsidizing the sale of power actually acquired elsewhere. In any event,
    the parties do not dispute the characterization of these contracts as “sales
    of electric power” for jurisdictional purposes. Moreover, the contractual
    provisions regarding monetary benefits would qualify as “final actions”
    within the catch-all provision even if not considered to be “sales of electric
    power under § 839c.” As we therefore do not need to sort out whether the
    monetary benefits provisions are reviewable as “sales of electric power”
    or under the catch-all for “other final actions and decisions by the . . .
    Administrator,” we do not do so.
    16534         PACIFIC NORTHWEST GENERATING v. DOE
    sell power to the DSIs under § 839c; (2) whether BPA is per-
    mitted to offer the DSIs monetary benefits in lieu of deliver-
    ing physical power; (3) whether BPA may offer contract
    terms to Port Townsend that differ from those offered to the
    aluminum DSIs; and (4) whether BPA must treat Port Town-
    send as a “new large single load” for the purposes of its con-
    tract with Clallam.16
    Alcoa and the Cooperative also challenge the actual rates
    incorporated by BPA into the aluminum DSI contracts. Alcoa
    argues that it is entitled to purchase power from BPA at a
    cost-based rate, and that, under the monetary benefit provi-
    sions of its contract with BPA — which utilize a mutually
    agreed upon FPS rate as a baseline — it is, as a practical mat-
    ter, subject to a market-based rate.17 The Cooperative, on the
    16
    The Cooperative argues that the DSI Service ROD and the Supple-
    mental ROD are also final agency actions subject to our review. We find
    it unnecessary to decide this issue. The four DSI contracts — which, as
    we have already concluded, are final agency actions subject to our review
    — incorporate the final decisions made by BPA in the DSI Service ROD
    and/or the Supplemental ROD. Thus, there is no reason for this Court
    independently to review the RODs, whether or not they are final agency
    actions. Any issue that arises from the RODs and is ripe for review also
    arises from the contracts and is likewise ripe for review. Similarly, any
    issue unripe for adjudication is unripe under both the RODs and the con-
    tracts.
    17
    Determining the “rate” that applies to purchases of power by Alcoa is
    complicated because BPA opted to deliver a monetary benefit rather than
    physical power. As noted, BPA agreed to pay Alcoa the difference
    between the rate that Alcoa must pay to purchase physical power (i.e., the
    market rate) and the PF rate for the first 320 aMW of power Alcoa con-
    sumes each year. BPA, however, capped the price differential it is willing
    to pay at $24/MWh (or less if Alcoa uses more than one-half of its allotted
    capacity). Thus, if the market price of power exceeds the PF rate by more
    than $24/MWh (or the applicable cap), Alcoa must pay more than the PF
    rate for its power purchases, although still less than the market rate. In
    addition, Alcoa receives no payment — and therefore must pay the full
    market price — for purchases of power in excess of the 320 aMW limit
    imposed by BPA. In sum, BPA’s contract with Alcoa requires Alcoa to
    pay a market-based rate — although less than the market rate — for the
    first 320 aMW Alcoa purchases each year, and the full market rate for any
    purchases above 320 aMW.
    PACIFIC NORTHWEST GENERATING v. DOE           16535
    other hand, argues that the rate assumptions that determine the
    monetary benefit BPA pays to the aluminum DSIs are imper-
    missibly low and thereby result in an unlawful subsidy.
    This issue is ripe for review. While this Court ordinarily is
    not permitted to review rate-making decisions until those
    decisions are final and have been approved by FERC, see
    Ass’n of Public Agency Customers, 
    126 F.3d at 1177, 1179
    ,
    BPA affirmatively stated in the Supplemental ROD that “[a]
    formal rate proceeding is not legally required for BPA to
    negotiate a rate within [the FPS] rate schedule . . . and[,] in
    this case in particular, would add little or nothing to the record
    already developed . . . .” BPA, in other words, has indicated
    that it does not plan to seek approval from FERC of the rate
    assumptions underlying the monetary payments or use the for-
    mal rate-making procedures outlined in § 839e(i) with respect
    to those payments. Because the parties do not challenge
    BPA’s assertion that no formal rate-making procedure,
    including FERC approval, is required here, we assume, with-
    out deciding, that BPA is correct. As BPA plans to take no
    further action with respect to the amount of monetary benefits
    specified in the DSI contracts or the method by which they
    are calculated, the benefit mechanism represents the “consum-
    mation of the agency’s decisionmaking process” by which
    BPA’s “obligations . . . [were] determined,” see Bennett v.
    Spear, 
    520 U.S. 154
    , 178 (1997) (internal quotation marks
    and citations omitted), and thus qualifies as a final agency
    action subject to our review under the catch-all review cate-
    gory.
    For similar reasons, Industrial Customers’ challenge to the
    rate applicable to the sale of power to Clallam is also ripe for
    review. Industrial Customers argues that the BPA/Clallam
    contract rate is impermissibly low because it is “not the DSI
    rate, the NR rate for new large single loads, or the market
    price of electricity.” Like the rate used to calculate the level
    of the aluminum DSIs’ monetary benefit, the BPA/Clallam
    contract rate is a negotiated rate made pursuant to the FPS
    16536          PACIFIC NORTHWEST GENERATING v. DOE
    rate schedule. As noted, BPA asserts that it is not legally
    required to seek FERC approval of a rate negotiated under the
    FPS rate schedule.18 Because the agency provides no indica-
    tion that it nonetheless plans to seek FERC approval of the
    Clallam contract rates,19 we can only assume that it does not
    plan to do so. A review of BPA’s notice of proposed 2007
    wholesale power rates, which describes the scope of BPA’s
    2007 wholesale rate-making process, confirms this assump-
    tion. See 
    70 Fed. Reg. 67,685
     (Nov. 8, 2005). In the ratemak-
    ing notice, BPA states:
    The DSI Service decisions [embodied in the RODs]
    finalized and established the manner and method by
    which BPA would provide service and benefits to its
    DSI customers[, including Port Townsend]. The
    decisions in that ROD resolved the method and level
    of service to be provided DSIs in the FY 2007-2011
    period. Pursuant to § 1010.3(f) of BPA Hearing Pro-
    cedures, the Administrator directs the Hearing Offi-
    cer to exclude from the record any material
    attempted to be submitted or arguments attempted to
    be made in the hearing which seek to in any way
    revisit the appropriateness or reasonableness of
    BPA’s decisions made in the DSI ROD.
    Id. at 67,689 (emphasis added). Because no parties contest
    BPA’s claim that the Clallam contract rates have been “final-
    ized” and “established,” we hold that ICNU’s challenge to
    that rate is ripe for review.
    In its final challenge, the Cooperative asserts that BPA
    18
    Again, because the parties do not challenge this assertion, we assume,
    without deciding, that BPA is not legally obligated to conduct a ratemak-
    ing proceeding either before or after it negotiates a rate under the FPS rate
    schedule.
    19
    In fact, BPA concedes that this Court has jurisdiction to review
    ICNU’s petition.
    PACIFIC NORTHWEST GENERATING v. DOE                   16537
    lacks statutory authority to allocate the costs it will incur
    under the contracts with the DSIs into the rates the agency
    charges its preference customers. We lack jurisdiction to
    review this challenge, because it is not, at present, ripe for
    adjudication. See, e.g., DBSI/TRI IV Ltd. P’ship v. United
    States, 
    465 F.3d 1031
    , 1038 (9th Cir. 2006).
    It has long been established in this circuit that petitions
    seeking review of BPA’s rate-making decisions — including
    both the allocation to rates of the costs of acquiring additional
    power, and language in power sales contracts affecting rate-
    making — are not reviewable until FERC has approved the
    rates in question. See Ass’n of Pub. Agency Customers, 
    126 F.3d at 1177, 1179
    ; Pub. Utils. Comm’n of Cal. v. FERC, 
    814 F.2d 560
    , 561 (9th Cir. 1987); Pub. Utils. Comm’r of Oregon
    v. BPA, 
    767 F.2d 622
    , 629 (9th Cir. 1985) (“If FERC fails to
    correct any defects in the methodology [which affected rate-
    setting], redress is available in the court of appeals,” where
    “any . . . cognizable challenges will be fully reviewable
    . . . .”).20 Until then, we lack jurisdiction to review PNGC’s
    challenge to BPA’s allocation of the costs of the DSI con-
    tracts to its members’ rates.
    20
    Although ripeness concerns preclude our consideration of PNGC’s
    challenges to BPA’s allocation of the costs of contracting with the DSIs,
    no such concerns limit our jurisdiction to review BPA’s authority to con-
    tract with the DSIs, and more specifically, to provide monetary benefits
    in lieu of physical power or to supply power at a rate that has been final-
    ized. In considering the ripeness of petitions challenging BPA contracts,
    we have distinguished between challenges to contractual provisions on the
    grounds that those provisions will affect future rate-making and cost allo-
    cation decisions, and challenges premised on the contention that the
    agency lacks statutory authority to agree to specific contractual terms,
    even though the injury asserted is those terms’ effect on customers’ rates.
    See Cal. Energy Res. Conservation & Dev. Comm’n v. Johnson, 
    807 F.2d 1456
    , 1458-59, 1461 (9th Cir. 1986) (dismissing as unripe claims that con-
    tractual provisions unlawfully impair BPA’s future rate-making and cost
    allocation procedures, while reviewing claim that contract violates NWPA
    requirements governing resource acquisition in § 839d(b)).

    III.   Merits
    A.   Standard of Review
    Petitioners here challenge decisions made by BPA in the
    DSI Service ROD and Supplemental ROD and embodied in
    the DSI contracts. We affirm BPA’s actions unless they are
    “arbitrary, capricious, an abuse of discretion, or in excess of
    statutory authority.” Aluminum Co. of Am. v. BPA, 
    903 F.2d 585
    , 590 (9th Cir. 1990). The basis for each of the challenges
    brought here is a contention that BPA has exceeded its author-
    ity under its governing statutes — the Project Act, the Trans-
    mission Act, the NWPA and the RPA — or that its decisions
    are arbitrary and capricious.

    struction is unreasonable.” Ass’n of Pub. Agency Customers,

    of “how best to further BPA’s business interests consistent

    to BPA to fill. Ass’n of Pub. Agency Customers,

     (internal quotation marks omitted). Applying appropri-
    ate deference, we uphold the agency’s assessment of whether
    its actions “further BPA’s business interests consistent with
    its public mission,” so long as the assessment is not unreason-
    able. 
    Id.
    B. BPA’s Obligation To Supply the DSIs’
    Requirements for Physical Power at a Cost-Based Rate
    Alcoa, the Cooperative, and BPA each offers a different
    interpretation of BPA’s statutory authority to sell power to the
    DSIs. Alcoa asserts that § 839c(d) obligates the agency to sell
    DSIs power at a cost-based rate. By contrast, the Cooperative
    contends that § 839c(d) is no longer operative, and that BPA
    therefore has no authority to sell power to DSIs thereunder,
    but instead must price its sales to DSIs at market rates. BPA
    argues for a middle ground: it maintains that § 839c(d) autho-
    rizes but does not obligate it to sell power to the DSIs. The
    agency does not stop there, however. It further contends that,
    because it is not obligated to sell power to the DSIs, it may
    use its § 839c(f) authority to sell the DSIs power at an FPS
    rate without first offering them power at the cost-based IP
    rate.
    For the reasons discussed in detail below, we conclude that
    none of these positions is entirely correct. We agree with BPA
    that § 839c(d) authorizes but does not obligate the agency to
    sell power to the DSIs. However, we also hold that, if the
    agency chooses to offer firm power to the DSIs, whether pur-
    suant to its § 839c(d) or § 839c(f) authority, it must first offer
    them the IP rate.
    16540          PACIFIC NORTHWEST GENERATING v. DOE
    1.   Obligation To Sell Power to the DSIs
    Alcoa argues that BPA’s decision to guarantee only a
    capped, monetary benefit to the aluminum DSIs in the con-
    tracts violated the NWPA, because the NWPA creates a per-
    petual obligation for BPA to satisfy the DSIs’ full energy
    requirements through sales of power at a cost-based rate. The
    Cooperative claims, on the other hand, that since the expira-
    tion in 2001 of the initial long term contracts mandated by
    § 839c(d)(1)(B), BPA no longer has authority to sell power to
    the DSIs under § 839c(d)(1), and, therefore, any such sale
    must be authorized by § 839c(f)’s provisions for the agency’s
    sale of surplus power at a market rate. Compare 16 U.S.C.
    § 839c(d)(1)(A) (“[BPA] is authorized to sell in accordance
    with this subsection electric power to existing direct service
    industrial customers.”) with § 839c(f) (“[BPA] is authorized
    to sell, or otherwise dispose of, electric power, including
    power acquired pursuant to this and other Acts, that is surplus
    to [its] obligations incurred pursuant to subsections (b), (c),
    and (d) of this section, in accordance with this and other Acts
    applicable to [BPA] . . . .”). Because, as we explain, Congress
    has not “clearly expressed [its] intent” in § 839c(d), we defer
    to BPA’s reasonable construction of the statutory text. Ass’n
    of Pub. Agency Customers, 
    126 F.3d at 1169

    hold here — as we have previously assumed, but not decided21

    tomer an initial long term contract that provides such
    customer an amount of power equivalent to that to
    which such customer is entitled under its contract
    dated January or April 1975 providing for the sale of
    “industrial firm power.”
    Alcoa maintains that the use in § 839c(d)(1)(B) of the term
    “initial” in describing the initial long term contracts indicates
    Congress’s intent that BPA is required to enter into successor
    agreements. Alcoa suggests that any interpretation to the con-
    trary would render Congress’s use of the word “initial”23
    superfluous, in contravention of basic principles of statutory
    construction. Boise Cascade Corp. v. EPA, 
    942 F.2d 1427

    Although the Supreme Court noted in Alcoa that, under the NWPA,
    the “preference rules [for regional customers] will apply to any subsequent
    contracts made with DSIs [following the initial long-term agreements],”
    it expressed no view regarding whether such “subsequent contracts”
    would or could include agreements for sales of firm power under
    § 839c(d). 467 U.S. at 395 n.10.

    16542       PACIFIC NORTHWEST GENERATING v. DOE
    § 839c(d)(1)(A), means that BPA’s authority to sell power to
    the DSIs extends only to the “initial long term contracts”
    specified in § 839c(d)(1)(B), particularly because § 839c
    (d)(3) states that the agency “shall not sell amounts of electric
    power, including reserves, to [the] existing [DSIs] in excess
    of the amount permitted under [§ 839c(d)](1),” unless specific
    requirements, not present here, are met.
    The statutory text is far from clear, but, for several reasons,
    does not compel the conclusion that successor sales agree-
    ments with the DSIs under § 839c(d) are prohibited.
    First, § 839c(d)(3) specifies neither what is meant by the
    “the amount permitted under [§ 839c(d)](1),” nor, therefore,
    what additional sales are prohibited. It is true that the provi-
    sion could be read to ban any sales of industrial firm power
    subsequent to those made under the initial long term con-
    tracts. On the other hand, it also could be understood as pro-
    hibiting only concurrent sales — that is, while the original
    long-term contracts were still in effect — “in excess of the
    amount permitted under [§ 839c(d)](1),” but not affecting
    subsequent sales of power — that is, after the initial agree-
    ments expired.
    [1] BPA has adopted the latter interpretation. Its position is
    that it now can make new sales of power to the DSIs under
    § 839c(d)(1)(A), even though it previously had asserted in
    Kaiser Aluminum & Chem. Corp. v. BPA, 
    261 F.3d 844
     (9th
    Cir. 2001), that it could not make such sales during the term
    of the initial agreements. See 
    id. at 849-850
     (discussing
    BPA’s position that during the term of the initial long term
    contracts, the agency could not sell power under § 839c(d) in
    addition to that provided under the initial long-term agree-
    ments mandated in § 839c(d)(1)(B)). BPA’s understanding of
    § 839c(d)(3) is a reasonable construction of ambiguous lan-
    guage and is therefore entitled to Chevron deference. The
    agency’s construction of the subsection does not contradict
    BPA’s position at the time of Kaiser, because Kaiser involved
    PACIFIC NORTHWEST GENERATING v. DOE           16543
    sales during, rather than after, the term of the initial agree-
    ments. See 261 F.3d at 849-850.
    Second, the use of the phrase “initial contract” gives rise to
    a reasonable inference that contracts following the initial long
    term agreements are not precluded; “initial” suggests that oth-
    ers may follow. The statutory context lends considerable sup-
    port to this interpretation, as it provides for “initial long-term
    contracts” for BPA’s preference customers and the IOUs as
    well as for the DSIs, see § 839c(g)(1), and definitively con-
    templated follow-on contracts, after the term of the initial
    agreements, for those groups of customers. See § 839c(b)(1),
    (b)(3), (c)(1); see also Ass’n of Pub. Agency Customers, 
    126 F.3d at 1166
     (noting that “[t]he DSIs’ 1981 Contracts with
    BPA required any DSI wanting to continue purchasing BPA
    power after the 20-year term to request a replacement contract
    by June 30, 1993,” thereby assuming the authority, but not the
    obligation, to enter into such contracts).
    Third, the inclusion of § 839c(d)(1)(A) in the Act as a sepa-
    rate, general grant of authority to BPA to sell power to the
    DSIs also suggests that the agency’s authority to do so is not
    limited to the specific mandate to offer initial long-term con-
    tracts set forth in § 839c(d)(1)(B). Subsection 839c(d)(1)(A)
    states what BPA “is authorized” to do — sell power — with-
    out specifying any time limitation; subsection (d)(1)(B) pro-
    vides what BPA “shall” do with respect to a limited time
    period. BPA’s authorized-but-not-obligated interpretation
    thus has the advantage of giving full effect to the statutory
    text. See Cent. Montana Elec. Power Coop., Inc. v. Adm’r of
    the BPA, 
    840 F.2d 1472
    , 1478 (9th Cir. 1988). In contrast,
    under the Cooperative’s interpretation, the general authoriza-
    tion contained in subsection (A) is superfluous; subsection (B)
    would suffice if all that was intended was an obligation to
    enter into one set of contracts.
    Finally, BPA’s authorized-but-not-obligated understanding
    of the interrelationship of subsections (A) and (B) is also con-
    16544       PACIFIC NORTHWEST GENERATING v. DOE
    sistent with the Act’s legislative history. The House Interior
    Committee’s report on S. 885 states that “[s]ection 5(d)(1)
    authorizes [BPA] to sell power to its existing direct-service
    industrial customers and requires [the agency] to offer to such
    customers initial long-term power sale contracts.” H.R. Rep.
    No. 96-976, pt. 2, at 34 (1980) (emphasis added). Similarly,
    the House Commerce Committee Report on S. 885 — the bill
    that became the NWPA, see Cal. Energy, 807 F.2d at 1464 —
    states that “[s]ection 5(d) authorizes the Administrator to sell
    power to existing direct service industrial customers.” H.R.
    Rep. No. 96-976, pt. 1, at 61 (1980). The report goes on to
    explain that, in addition to mandating that “[i]nitial long-term
    20-year contracts are to be offered by BPA” to the DSIs,
    “[s]ubsequent contracts . . . are authorized but not mandated.”
    H. Rep. No. 96-976, pt.1, at 61 (1980).
    [2] We conclude that BPA is authorized to sell the DSIs
    non-surplus power under § 839c(d)(1)(A).
    At the same time, we do not adopt Alcoa’s suggested inter-
    pretation — that BPA is obligated, rather than merely autho-
    rized, to sell power to the DSIs. Contrary to Alcoa’s
    suggestion, the phrase “initial long-term contract” does not
    necessarily indicate that successor agreements are required
    rather than permitted. That an object is at the “beginning” of
    a process in no way dictates that the process will continue in
    perpetuity. Certainly, every time Alcoa signs an “initial con-
    tract” with one of its customers, the company does not believe
    it is entering into a lifelong commitment.
    Alcoa nonetheless contends that if Congress had meant to
    obligate BPA to enter into only one long-term contract with
    the DSIs, it would have simply referred to a “long-term con-
    tract,” not an “initial long-term contract.” But “initial” could
    have been meant just as a reference back to subsection (A),
    confirming that there may be later contracts as well.
    The interpretation Alcoa suggests is not one that we, BPA,
    or, for that matter, Alcoa itself, previously has taken from the
    PACIFIC NORTHWEST GENERATING v. DOE             16545
    text of § 839c(d)(1)(B). See M-S-R, 
    297 F.3d at 838
    . Nor is
    Alcoa’s perpetual obligation position consistent with the
    meaning that members of Congress involved in the NWPA’s
    enactment ascribed to the section. See H.R. Rep. No. 96-976,
    pt. 1, at 61 (stating that after the “[i]nitial long-term 20-year
    contracts[,] . . . . [s]ubsequent contracts . . . are authorized but
    not mandated.”).
    Alcoa sees evidence to the contrary in the legislative his-
    tory of the NWPA and in BPA’s own understanding of the
    Act at the time of its passage. The company points to a state-
    ment in the House Interior Committee Report on S. 885 that
    § 839c(b) “mandates continued BPA power sales to existing
    [DSIs],” H.R. Rep. No. 96-976 Pt. 2 at 48, and a statement by
    BPA’s administrator that the NWPA “contemplates in
    [§ 839c(d)] additional, future contracts with each existing
    [DSI]” following the initial agreements. Alcoa reads too much
    into these statements.
    Nothing in the above-quoted sentence from the Committee
    Report or its surrounding text indicates that “continued . . .
    power sales” is for sales after the initial agreements, as
    opposed to the initial agreements themselves (which are, of
    course, “mandate[s]”). Indeed, additional language in the
    Committee Report supports the latter interpretation: “Existing
    DSIs will receive the amount of power to which they are enti-
    tled under present ‘Industrial Firm’ power sales agreements.”
    H.R. Rep. No. 96-976, pt. 2, at 48. Moreover, BPA’s adminis-
    trator’s statement that subsequent contracts are “contemplat-
    ed” under § 839c(d) — a far from imperative term — is
    completely consistent with the view that the Act “authorized
    but did not obligate BPA to sell the DSIs any power.” M-S-R,
    
    297 F.3d at 838
    .
    [3] Alcoa further argues that because “[u]nder accepted
    canons of statutory interpretation, we must interpret statutes
    as a whole,” Boise Cascade, 
    942 F.2d at 1432
    , Congress’s
    mention of sales to the DSIs in various sections of the NWPA
    16546       PACIFIC NORTHWEST GENERATING v. DOE
    shows that it intended BPA to have an ongoing obligation to
    sell power to them. The strongest support for this contention
    is the requirement in § 839c(d)(1)(A) that “sales [to the DSIs]
    shall provide a portion of the [BPA]’s reserves for firm power
    loads.” Alcoa maintains that this language requires ongoing
    sales by BPA to the DSIs, so as to provide these reserves.
    [4] Again, the plain text of the statute permits but does not
    command the interpretation Alcoa suggests. The language in
    question could be read to recognize such a requirement. But
    it also reasonably can be read to mean that if BPA elects to
    sell power to the DSIs under § 839c(d), a portion of this
    power must be available to BPA as reserves. BPA adopted the
    latter interpretation as more consistent with the NWPA as a
    whole, which, according to BPA, indicates that Congress was
    focused on assuring that BPA has some reserves to protect its
    operations, rather than on the particular source of these
    reserves. See, e.g., § 839a(17) (defining “[r]eserves” as “elec-
    tric power needed to avert particular planning or operating
    shortages . . . [that are] available to [BPA] (A) from resources
    or (B) from rights to interrupt . . . portions of the electric
    power supplied to customers.”) (emphasis added). BPA’s
    interpretation of the ambiguous “reserves” language is reason-
    able, and so entitled to Chevron deference.
    Nor do the other sections of the NWPA which discuss sales
    to the DSIs compel us to reach the conclusion Alcoa pro-
    poses. Contrary to Alcoa’s assertion, the fact that
    § 839e(b)(2)(A)(I) requires BPA to take into account the costs
    of “[DSI] customer loads which are . . . served by [BPA]”
    (emphasis added), in its rate ceiling does not prove that DSI
    loads must be served by BPA. Again, it is just as reasonable
    to read the provision to require that if BPA chooses to serve
    DSI loads, it must take the costs of such service into account.
    Along these same lines, the fact that we have construed
    § 839b(d)(2), which provides that BPA must act in accor-
    PACIFIC NORTHWEST GENERATING v. DOE                 16547
    dance with a regional power plan,24 to require that BPA’s
    regional plan reflect loads for which the DSIs have requested
    service, see M-S-R, 
    297 F.3d at 844
    , does not mean that BPA
    is obligated to satisfy that request. Instead, our stated assump-
    tion when announcing this holding was that BPA is “autho-
    rized but . . . not obligate[d]” to serve the DSIs. 
    Id. at 838
    .
    Alcoa’s position that the NWPA must be understood to
    mandate perpetual sales to the DSIs is further undermined by
    another consideration: When Congress did want to impose an
    obligation to supply a class of customers with their require-
    ments for power, it did so quite explicitly. With regard to
    preference customers and the IOUs, the NWPA provides that,
    “[w]henever requested, [BPA] shall offer to sell to each
    requesting public body and cooperative entitled to preference
    and priority . . . and to each requesting [IOU] electric power
    to meet the firm power load of such [customer] . . . .”
    § 839c(b)(1) (emphasis added). The DSIs are not mentioned
    as customers to whom this language applies, and the NWPA
    does not contain any other equivalent provision concerning
    BPA’s sales to them. While Congress specifically directed
    BPA to provide “initial long-term contracts” to all of its tradi-
    tional classes of customers, see § 839c(g)(1)(A)-(D), it only
    mandated that the agency provide power “whenever request-
    ed,” § 839c(b)(1), to only some of them — and not to the
    DSIs. We must infer, therefore, that Congress intended to
    exclude service to the aluminum DSIs from this general man-
    date. See White v. Lambert, 
    370 F.3d 1002
    , 1011 (9th Cir.
    2004) (“It is axiomatic that when Congress uses different text
    in ‘adjacent’ statutes it intends that the different terms carry
    a different meaning.”); see also, e.g., Barnhart v. Peabody
    24
    Section 839b(d)(2) states: “Following adoption of the [regional con-
    servation and electric power] plan and any amendment thereto, all actions
    of the Administrator pursuant to section 839d of this title [— which con-
    cerns the acquisition of resources to meet BPA’s contractual obligations
    —] shall be consistent with the plan and any amendment thereto, except
    as otherwise specifically provided in this chapter.”

    Coal Co., 
    537 U.S. 149
    , 168 (2003) (applying the canon of
    expressio unius est exclusio alterius).25
    [5] We conclude, in sum, that BPA’s interpretation of the
    NWPA as authorizing but not obligating the agency to sell
    nonsurplus firm power to the DSIs is a reasonable one. We
    therefore reject both the Cooperative’s contention that such
    sales are prohibited and Alcoa’s contention that BPA has an
    ongoing obligation to sell power to the DSIs under
    § 839c(d)(1).
    2.      Obligation to Offer Power at a Cost-Based Rate
    As explained in note 17, supra, under the monetary benefit
    provisions in the aluminum DSI contracts, the rate the DSIs
    ultimately pay for the physical delivery of power once the
    BPA monetary payments are taken into account, while below
    the market rate, is nonetheless subject to market fluctuations
    and increases when market rates rise above a certain point.
    Unhappy with this exposure to market volatility, Alcoa argues
    25
    The difference in treatment between sales to preference customers and
    IOUs on the one hand and sales to DSIs on the other is reflected in the leg-
    islative history of the NWPA. Concerning sales of power to preference
    customers and the IOUs, the House Interior Committee Report states,
    [S]ection 5(b)(1) requires the Administrator, if requested, to enter
    into long-term power sale contracts with both preference and
    investor-owned utilities in the region to supply them with the
    firm power they need to meet their firm loads . . . .
    H. Rep. No. 96-976, pt. 2, at 33 (1980). “The practical effect of this man-
    date,” the report observes, is that “preference utilities . . . will continue to
    have all their firm power needs in the region met by BPA . . . .” Id. No
    such consequences are noted in regard to sales to the DSIs. See id. at 34
    (“Section 5(d)(1) . . . authorizes the Administrator to sell power to its
    existing direct-service industrial customers and requires him to offer to
    such customers initial long-term power sale contracts. . . .”) (emphasis
    added). Thus, the committee report suggests that Congress was creating an
    ongoing requirement that BPA provide “long-term power sale contracts”
    to preference customers and the IOUs, but was only requiring “initial
    long-term power sale contracts” for the DSIs. Id. (emphasis added).
    PACIFIC NORTHWEST GENERATING v. DOE           16549
    that BPA must sell it power at a purely cost-based rate that
    does not vary with market rates. By contrast, BPA asserts that
    its governing statutes do not obligate it even to offer the DSIs
    a cost-based rate, let alone supply power (or its monetary
    equivalent) at such a rate. Rather, BPA contends that it may
    offer power to the DSIs as “surplus” power under § 839c(f)
    at the FPS rate schedule — which, as discussed, we are
    assuming permits BPA to offer power at any mutually-agreed
    upon rate, including market-based rates — without first offer-
    ing that power to the DSIs at one of its FERC-approved, cost-
    based rates.
    Alcoa does not clearly indicate which of BPA’s three pub-
    lished cost-based rates — the PF rate, the IP rate, and the NR
    rate — it believes it is statutorily entitled to. Because the IP
    rate, which § 839e(c) describes as “the rate . . . applicable to
    direct service industrial customers,” is the most obvious con-
    tender, we consider that rate first.
    a.   The IP rate
    According to BPA’s interpretation of the NWPA, the IP
    rate applies only to sales that BPA makes to DSIs pursuant to
    § 839c(d). Id. BPA then notes, as we have also concluded,
    that § 839c(d) authorizes, but does not obligate, the agency to
    sell power to the DSIs. The agency concludes from this cir-
    cumstance that any power in excess of that (1) which is
    requested by its preference customers or IOUs under
    § 839c(b) and (c), or (2) which the agency itself elects to sell
    the DSIs under § 839c(d), qualifies as “[s]urplus power” that
    BPA is authorized “to sell, or otherwise dispose of” under
    § 839c(f). BPA sells such “surplus power” pursuant to the
    FPS rate schedule at a negotiated FPS rate. Thus, by refusing
    to sell to the DSIs pursuant to its authority under section
    839c(d), BPA believes, it can effectively create “surplus
    power” that it can then offer to sell to the DSIs (or any other
    in-region customers) at any rate it chooses.
    16550         PACIFIC NORTHWEST GENERATING v. DOE
    BPA’s interpretation of § 839e(c) and its relationship with
    § 839c(d) is unreasonable on two grounds. First, it ignores the
    plain language of the statute and, in so doing, renders the IP
    rate superfluous. Second, it runs counter to the NWPA’s leg-
    islative history, which evinces Congress’s intent that BPA
    offer power to the DSIs, if at all, at the IP rate, not at some
    other rate of its choosing. For these reasons, we hold that
    BPA, when entering into contracts for the sale of firm power
    to a DSI, must initially offer the IP rate.26 Only after the DSIs
    have refused to purchase power at the IP rate may BPA offer
    them power under the FPS rate schedule.
    26
    This holding pertains to sales, like the contracts at issue, of “firm
    power” to DSI customers. See Wholesale Power Rate Schedule at 130
    (defining “firm power” as “electric power (capacity and energy) that BPA
    will make continuously available under contracts executed pursuant to
    Section 5 of the Northwest Power Act”). We are not deciding whether
    BPA must offer the IP rate to DSIs when selling “nonfirm” power.

    Volume 2 of 2
    PACIFIC NORTHWEST GENERATING v. DOE          16555
    i.   Statutory Analysis
    [6] The language of § 839e(c), which is entitled “Rates
    applicable to direct service industrial customers,” does not
    support BPA’s contention that the IP rate applies only to sales
    made pursuant to § 839c(d). Section 839e(c) states, in rele-
    vant part,
    16556       PACIFIC NORTHWEST GENERATING v. DOE
    (1) The rate or rates applicable to direct service
    industrial customers shall be established — . . .
    (B) for the period beginning July 1, 1985, at a level
    which the Administrator determines to be equitable
    in relation to the retail rates charged by the public
    body and cooperative customers to their industrial
    consumers in the region.
    (2) The determination under paragraph (1)(B) of
    this subsection shall be based upon the Administra-
    tor’s applicable wholesale rates to such public body
    and cooperative customers and the typical margins
    included by such public body and cooperative cus-
    tomers in their retail industrial rates but shall take
    into account —
    (A) the comparative size and character of the loads
    served,
    (B) the relative costs of electric capacity, energy,
    transmission, and related delivery facilities provided
    and other service provisions, and
    (C) direct and indirect overhead costs, all as related
    to the delivery of power to industrial customers,
    except that the Administrator’s rates during such
    period shall in no event be less than the rates in
    effect for the contract year ending on June 30, 1985.
    The statutory text does not reference section 839c(d) or other-
    wise suggest the limitation BPA reads into it. Rather, it
    straightforwardly — and generally — states “the rate or rates
    applicable to direct service industrial customers shall be
    established” pursuant to certain standards. § 839e(c) (empha-
    sis added).
    PACIFIC NORTHWEST GENERATING v. DOE                   16557
    Second, and more importantly, BPA’s position would ren-
    der the IP rate a nullity. If this Court were to adopt BPA’s
    interpretation of §§ 839e(c) and 839c(d), BPA would retain
    complete discretion over the decision whether to offer DSIs
    power at the purely cost-based IP rate or at an FPS rate of
    BPA’s choosing, including a market-based rate higher than
    the IP rate. Basic economics establishes that a rational seller
    of a commodity product, if provided a choice between the
    market rate and a cost-based rate, will either choose to offer
    the market rate (if the market rate exceeds the cost-based rate)
    or be forced to accept the market rate (if the market rate is
    below the cost-based rate). Thus, BPA, if acting rationally and
    in accordance with its “mandate to operate with a business-
    oriented philosophy,” see Ass’n of Pub. Agency Customers,
    
    126 F.3d at 1171
    , would never sell power to the DSIs at the
    IP rate.27 Why would Congress have required BPA to “estab-
    lish” a rate, specified the formula it would be “based upon,”
    and stated that “the rate or rates” are “applicable to [DSI] cus-
    tomers,” § 839e(c) (emphasis added), if that rate could not
    possibly apply to any sale?
    In its initial ROD, BPA states that it chose not to use the
    IP rate as the baseline for calculating the monetary benefits
    payable to the DSIs because it believed the DSIs could not
    afford the rate and would therefore reject any contract that
    provided power (or its monetary equivalent) at that rate.
    Whether or not this assertion is correct, it does not excuse
    BPA’s failure to at least offer the rate, because the DSIs will
    not always prefer an FPS rate.
    [7] In Kaiser, for example, the DSIs sought to purchase
    power at the IP rate once that rate became more economical
    than a market-based FPS rate. See Kaiser, 261 F.3d at 848.
    Were we to agree that BPA has complete discretion to select
    between the IP rate and an FPS rate, BPA would, as noted,
    27
    Except, of course, in the extremely unlikely event that the IP rate and
    the market rate were identical.
    16558          PACIFIC NORTHWEST GENERATING v. DOE
    always choose an FPS rate, and the DSIs would never receive
    the option to purchase power at the IP rate. Our conclusion is
    supported by BPA’s actions in Kaiser, where, when presented
    with the opportunity to charge an FPS rate rather than the IP
    rate, BPA did so. See id. Because Congress must have
    intended the IP rate to apply to at least some contracts, we
    conclude that BPA must at least offer the IP rate, established
    pursuant to section 839e(c), to the DSIs before entering into
    a contract with the DSIs at a rate authorized under the FPS
    rate schedule.28
    ii.   Legislative History
    Our conclusion that BPA’s interpretation of its governing
    statutes is unreasonable is further underscored by the fact that
    it contradicts the legislative history of the Act. That history
    contains extensive evidence that Congress intended the IP rate
    to be the default price for sales of power to the DSIs, and
    28
    At oral argument, as in its opening brief, Alcoa alleged that the rate
    BPA agreed to charge Clallam — a rate “equal to [the PF rate] . . . plus
    the typical industrial margin used to establish the [IP rate]”— “mirror[s]
    the statutory standard for [the IP] rate[ ] found at” § 839e(c). See
    § 839e(c)(1)-(2) (stating that the IP rate shall be established at a rate “eq-
    uitable in relation to . . . [the PF rate plus] the typical margins included
    by [public utilities and cooperatives] in their retail industrial rates [plus
    other factors]”). Counsel for Alcoa then asserted that, because the Clallam
    contract rate is equivalent to the IP rate, the company is entitled to the
    Clallam contract rate. This argument is without merit for two reasons.
    First, although the language BPA used to describe the Clallam contract
    rate is similar to the language that describes the method by which the IP
    rate is calculated, the Clallam contract expressly indicates that the rate is
    an agreed-upon FPS rate, not the IP rate. Second, the rate which appears
    in the Clallam contract could not possibly be the equivalent of the rate that
    BPA is required to establish under § 839e(c), because the agreed-upon rate
    of approximately $28/MWh is $17/MWh less than the published IP rate
    for the year ending September 30, 2007. In short, although the Clallam
    contract rate appears, at first glance, to be the same thing as the IP rate,
    it is not the IP rate to which the DSIs are entitled. The IP rate that BPA
    must offer the DSIs is the one it establishes pursuant to § 839e(c) and (i).
    PACIFIC NORTHWEST GENERATING v. DOE            16559
    gives little indication that Congress intended BPA to have dis-
    cretion to offer them power at a self-created FPS rate instead.
    First, relevant Committee Reports make clear that “rates
    applicable to direct service industrial customers” are those set
    under Section 7(c) of the Act, i.e., § 839e(c). H.R. Rep. No.
    96-976, pt. 1, at 69 (“Section 7(c) prescribes the rates applica-
    ble to direct service industrial customers.”); S. Rep. No. 96-
    272 at 59 (“This rate applies to all ‘Industrial Firm’ sales to
    BPA’s direct-service industries . . . [for] 1985-86 and all
    future [sales].”) (emphasis added).
    By contrast, there is no indication that Congress intended
    BPA to offer power to the DSIs at rates set under § 839e(f),
    when it can do so at a rate set under § 839e(c). The House
    Commerce Committee Report describes Section 7(f) of the
    Act, which became 16 U.S.C. § 839e(f), as providing the
    authority for “establish[ing] the rate or rates for sales to
    investor-owned utilities other than sales pursuant to the [resi-
    dential] exchange [program], preference customers for power
    needed to meet the requirements of new large single ‘loads’
    and all other miscellaneous sales.” H.R. Rep. No. 96-976, pt.
    1, at 69. Noticeably absent from this list are direct sales to
    DSIs. Similarly, sales made under § 7(f) are described in the
    Senate Report as exclusive of sales to the DSIs under §7(c)
    (§ 839e(c)). Compare S. Rep. 96-272 at 56 (discussing § 7(c)
    and stating that “after June 1985 the rate applicable to BPA
    direct service industrial customers will be based upon the
    retail rates applicable to industry served by BPA preference
    utility customers.”) with id. at 60 (“[S]ubsection 7(f) of the
    proposed legislation[:] . . . [t]his rate applies to all other firm
    sales including but not limited to (1) Investor-owned utility
    total load growth . . . (2) New Large Industrial loads served
    by preference customers; (3) Amounts of additional power
    needed by Regional Rate loads . . . once such loads exceed the
    16560          PACIFIC NORTHWEST GENERATING v. DOE
    capability of the Federal Base System resources and the IOU
    Exchange Power . . . .”) (emphasis added).29
    iii.   Kaiser Aluminum
    BPA’s capstone argument on this point is that its decision
    not to sell power to the DSIs at the IP rate cannot be unrea-
    sonable as it is consistent with the decision in Kaiser Alumi-
    num & Chem. Corp. v. BPA, 
    261 F.3d 843
     (9th Cir. 2001). In
    Kaiser Aluminum,
    Petitioners argue[d] that the only rate established for
    the sale of the Surplus Firm Power is the IP-96 rate,
    and BPA abused its authority when it refused to sell
    the Surplus Firm Power at that rate. Petitioners fur-
    ther contend[ed] that because BPA refused to sell
    Petitioners the Surplus Firm Power at the IP-96 rate
    and evidence indicates that BPA sold power at the
    FPS-96 rate outside the Pacific Northwest, Petition-
    ers were not granted their regional preference under
    the Preference Act.
    29
    Contrary to BPA’s assertions, the legislative history of 16 U.S.C.
    § 832m, the later-enacted provision which establishes “excess Federal
    power,” id., as a “subspecies of surplus power,” M-S-R-, 
    297 F.3d at 837
    ,
    does not support the agency’s contentions regarding the rate at which BPA
    must offer power that is not “excess federal power” to regional customers
    before selling it outside the region. Congress’s expectation that BPA
    “would offer excess power first to regional customers under the same
    essential rate . . . as for the proposed out-of-region sale[s],” H.R. Rep. No.
    104-293, at 91 (1995) is not a basis for inferring that the same would be
    true of sales that do not involve excess power.
    As the passage in the conference report that BPA cites in support of its
    argument makes clear, the only energy that can be sold as excess power
    is “power abandoned by regional customers and . . . power generated or
    purchased for the benefit of fish and wildlife.” 
    Id.
     A key reason for creat-
    ing the “excess federal power” category was to remove otherwise applic-
    able regional preference restrictions in the case of sales of power that has
    been “abandoned by regional customers.” 
    Id.
     The passage BPA cites does
    not speak to the “applicable rate schedule” for sales to regional customers
    of power that they have not “abandoned.” 
    Id.
    PACIFIC NORTHWEST GENERATING v. DOE                   16561
    
    261 F.3d at 848
    . The IP-96 rate was, at that time, the rate “ap-
    plicable to [DSI] customers” under § 839e(c), while the FPS
    rate was a rate schedule for sales of “all other . . . power,”
    under § 839e(f). See Kaiser, 
    261 F.3d at 850
    . Our holding in
    Kaiser was that “BPA acted reasonably and in conformity
    with governing statutes when it offered to sell [the DSIs] Sur-
    plus Firm Power at the FPS-96 rate, and rejected Petitioners’
    offers to purchase such power from BPA at the IP-96 rate.”
    
    Id. at 851
    . Despite a superficial similarity to the circum-
    stances of this case, for reasons we now explain Kaiser does
    not negate but, instead, underscores the unreasonableness of
    BPA’s interpretation of its governing statutes as applied here.
    Most importantly, BPA glosses over key distinctions
    between the statutory and factual context in Kaiser and the
    one we face here. In Kaiser, the DSIs sought to purchase
    power from BPA in 1999, prior to the 2001 expiration date of
    the initial longterm contracts mandated by the NWPA. See 
    id. at 846, 848
    . The DSIs had, however, terminated or waived
    portions of their purchase rights under the initial longterm
    contracts, so the power the DSIs wanted to buy was “surplus
    to BPA’s long term obligations” to them under the contracts.
    
    Id. at 846-47, 851
    .30
    30
    As we recounted in Kaiser, the reason the DSIs relinquished these
    rights was that in the mid-1990s the market price for electric energy, and,
    thus, the FPS rate, was, for a time, actually lower than the IP rate for
    power sold to the DSIs under the initial longterm contracts. 
    Id. at 846
    . As
    a result, “the market prevent[ed] BPA from selling any additional power
    to the DSIs under their [initial] power sales contract[s].” 
    Id. at 850
     (quot-
    ing BPA 1996 Rate ROD). When the DSIs terminated or waived the por-
    tions of their power allotments, the power they could have purchased
    under the initial contracts thus became surplus firm power. 
    Id. at 850
    (“[O]ne of the reasons BPA has available surplus power is because [DSI]
    Petitioners reduced their obligation to purchase power under their previous
    long term power sales contracts.”). When energy prices rose again in the
    late 1990s, making the IP rate attractive once again, these DSIs tried to
    obtain new agreements from BPA to purchase power at that rate. See 
    id. at 848
    .
    16562          PACIFIC NORTHWEST GENERATING v. DOE
    The agency’s position in Kaiser, therefore, was not simply
    that it had no obligation to make the new sales under the
    § 839e(c) rates that the DSIs wanted, but that it also lacked
    statutory authority to do so under § 839c(d). BPA’s conten-
    tion, which we accepted, was that the requested transactions
    would constitute a sale under § 839c(d) of power “in excess”31
    of the initial longterm contracts, which was prohibited by
    § 839c(d)(3).32 Kaiser, 
    261 F.3d at 850
    . BPA, we concluded,
    could not sell power to the DSIs at the IP-96 rate because this
    rate was established only for industrial firm power, which, at
    that time, could be sold only under the original longterm
    agreements. See 
    id. at 850
     (“[A]dditional power sales to DSIs
    are not covered by Section [839e](c), under which the IP-96
    rate was authorized, because that section requires the estab-
    lishment of rates for DSIs under Section [839c](d), the section
    which provides for the sale of Industrial Firm Power by
    means of long term contracts with the DSIs.”).
    In sum, the power the DSIs sought to purchase from BPA
    in Kaiser was energy that was not required by the agency’s
    preference customers or the IOUs, but that also could not be
    sold to the DSIs at the IP-96 rate. See id at 848-50. We did
    not face in Kaiser, as we do here, a situation in which the
    agency has failed to offer the DSIs contracts for industrial
    firm power at the IP rate even though it is authorized to do so.
    31
    Section 839c(d)(3) states: “The Administrator shall not sell amounts
    of electric power, including reserves, to existing direct service industrial
    customers in excess of the amount permitted under [§ 839c(d)(1)] unless
    [certain specific conditions are met].”
    32
    The position BPA articulated in Kaiser was that: (1) “the IP-96 rate”
    was “applicable [only] to the sale of Industrial Firm Power” (2) “Industrial
    Firm Power” is limited to power that “that BPA will make continuously
    available to a direct-service industrial (DSI) purchaser subject to the terms
    of the Purchaser’s power sales contract with BPA”; and (3) as a result, the
    DSIs “are entitled to purchase under the IP-96 rate only that amount of
    power each has agreed to purchase under the 1981 power sales contracts
    or the 1996 Block Sales Contracts.” Kaiser, 
    261 F.3d at 849
    .
    PACIFIC NORTHWEST GENERATING v. DOE           16563
    Indeed, BPA does not assert here, as it did in Kaiser, that
    its governing statutes preclude it from offering power to the
    DSIs at the IP rate. See 
    id. at 849
    . In fact, BPA makes the
    opposite assertion: It argues that it is statutorily authorized to
    sell firm power to the DSIs at the IP rate, but is simply choos-
    ing not to do so. Thus, BPA’s and this Court’s justification in
    Kaiser for allowing BPA to sell power at the FPS rate rather
    than the IP rate — namely, that BPA was precluded by statute
    from offering the IP rate due to its prior contractual obligation
    — is wholly absent here. See Kaiser, 
    261 F.3d at 850
    .
    Our interpretation of the governing statutes as requiring
    that BPA first offer the DSIs power at the IP rate is not only
    faithful to the statutes’ text, it is also more consistent with
    BPA’s own understanding at the time of Kaiser and before of
    the requirements of §§ 839c and 839e. The key claim raised
    by the DSIs in Kaiser was that BPA’s decision to offer energy
    only at the FPS-96 rate schedule was inconsistent with the
    agency’s position in its 1996 Rate ROD concerning the appli-
    cability of the FPS-96 and IP-96 rates. See Kaiser, 
    261 F.3d at 849
    . The position adopted by BPA in the 1996 Rate ROD
    was, in essence, the opposite of the one that the agency argues
    here. In the 1996 Rate ROD, BPA stated that
    BPA will not sell power to the DSIs under the FPS
    rate schedule if it is able to make the sale at the IP
    rate . . . . Any DSI load that BPA obtains under the
    FPS schedule rate is load it otherwise would have
    lost to the competition; BPA will make sales to the
    DSIs under the FPS rate schedule only when the
    alternative is the loss of the load. The FPS rate
    schedule is not an alternative to the IP-96 rate.
    Kaiser, 
    261 F.3d at 849
     (quoting 1996 Rate ROD). In other
    words, BPA’s position was that it would only sell power to
    the DSIs at an FPS rate if it was not “able to make the sale
    at the IP rate.” 
    Id.
     We relied upon this position of BPA’s in
    Kaiser, noting that
    16564       PACIFIC NORTHWEST GENERATING v. DOE
    [t]he fact that BPA indicated the IP and FPS rates are
    not interchangeable, and it will not make sales under
    the FPS rate when it can make sales at the IP rate,
    does not answer the question of when BPA is per-
    mitted to make sales under the IP rate. If BPA is not
    permitted to make sales of Surplus Firm Power
    under the IP rate, then it is not impermissibly substi-
    tuting the FPS rate for the IP rate.
    
    Id. at 850
    . Following the expiration of BPA’s pre-2001 con-
    tracts, the “question of when BPA is permitted to make sales
    under the IP rate,” 
    id.,
     now has a different answer, see Part
    III.B.1, supra. The interpretation of the NWPA that BPA
    adopted in the 1996 Rate ROD, and that we upheld as reason-
    able in Kaiser, therefore leads to a different outcome in this
    case.
    As we recently noted, “[a]n agency is entitled to change its
    course when its view of what is in the public’s interest
    changes[,]” but “an agency changing its course must supply
    a reasoned analysis indicating that prior policies and standards
    are being deliberately changed, not casually ignored . . . .”
    Nw. Envtl. Def. Ctr. v. BPA, 
    477 F.3d 668
    , 687-688 (9th Cir.
    2007) (internal quotation marks and citation omitted). Here,
    BPA does not simply ignore the interpretation of the NWPA
    that it relied upon in Kaiser. Instead, the agency argues that
    our holdings in that case now support a view of its authority
    quite contrary to its prior position. In other words, BPA asks
    us to accept that a change in course is no change at all. An
    agency that does not admit to have changed its position does
    not “supply a reasoned analysis” for having done so. 
    Id. at 687
    .
    We conclude that Kaiser supports, rather than conflicts
    with, our understanding that BPA does have an obligation to
    offer the DSIs a cost-based rate — namely, the IP rate —
    before declaring energy as surplus under § 839c(f) and selling
    it to the DSIs at a market-based — or other — FPS rate.
    PACIFIC NORTHWEST GENERATING v. DOE                   16565
    iv.    The Regional Preference Act
    Alcoa goes on to argue at length that the Regional Prefer-
    ence Act precludes BPA from offering power outside of the
    Pacific Northwest unless it first offers that power to in-region
    customers at a cost-based rate. As BPA correctly points out,
    the contracts at issue involve sales of power to customers (the
    DSIs) who are in-region customers; BPA is not, in other
    words, attempting in the challenged contracts to sell surplus
    power outside the Pacific Northwest. Moreover, BPA states in
    footnote 20 of its brief that it
    makes . . . offers [to sell surplus power outside the
    Pacific Northwest] by postings on its website. If
    such sales takes place and if, at that time, Alcoa
    believes BPA has not complied with its obligations
    under the Regional Preference Act, then Alcoa can
    challenge such sale(s) by filing a timely petition for
    review. At this juncture, however, there is no credi-
    ble issue that arises under the Regional Preference
    Act.
    Resp. Br. at 84 n.20. In light of BPA’s assurances that Alcoa
    can challenge out-of-region power sale contracts and the fact
    that it has not done so in this action, we hold that Alcoa’s
    RPA-based arguments are not ripe for adjudication at this time.33
    v.   Conclusion
    [8] We conclude that BPA’s interpretation of its governing
    statutes as providing authority to sell surplus power to the
    DSIs under § 839c(f) at an FPS rate without first offering to
    sell that amount of power under either § 839c(d) or § 839c(f)
    at a rate set under § 839e(c) is not reasonable. The statutory
    33
    Should Alcoa later challenge an out-of-region sale in the manner BPA
    describes, the agency, of course, will be bound by its representation in this
    case that such a challenge is procedurally proper.
    16566       PACIFIC NORTHWEST GENERATING v. DOE
    text of the NWPA, the agency’s own prior interpretation of
    the Act, and the NWPA’s legislative history, are all to the
    contrary. We therefore hold that BPA improperly refused to
    offer the aluminum DSIs energy at a rate set under § 839e(c)
    before selling them power at an FPS rate.
    b.   The PF rate
    [9] Having concluded that BPA must first offer DSIs the IP
    rate — and in light of Alcoa’s failure to identify which cost-
    based rate it thinks it deserves — we next consider whether
    the DSIs are also entitled to an offer at the PF rate. We hold
    that they are not. Section 839e(b), which provides for the
    establishment of the PF rate, expressly states the customer
    groups to which that rate applies: “public body, cooperative,
    and Federal agency customers within the Pacific Northwest
    and . . . [investor-owned] electric utilities [who participate in
    the residential exchange program].” § 839e(b). The DSIs are
    none of these. See Barnhart v. Peabody Coal Co., 
    537 U.S. 149
    , 168 (2003) (“[W]hen the items expressed are members
    of an associated group . . . the inference [is] that items not
    mentioned were excluded by deliberate choice . . . .”) (internal
    quotation marks omitted). In addition, the fact that Congress,
    in the very next subsection, defined a distinct rate applicable
    specifically — and solely — to “direct service industrial cus-
    tomers” demonstrates that it intended to treat the DSIs sepa-
    rately from those customer groups defined in § 839e(b). See
    § 839e(c). In sum, the plain language of § 839e(b) & (c) per-
    mits only one conclusion: that the DSIs are not entitled to the
    PF rate.
    C.   Monetization of Energy Contracts
    Both Alcoa and the Cooperative challenge BPA’s authority
    to offer the DSIs a monetary benefit in lieu of delivering
    physical power. Alcoa argues that the text, structure, and leg-
    islative history of the NWPA require BPA to physically
    deliver power. The Cooperative contends, likewise, that BPA
    PACIFIC NORTHWEST GENERATING v. DOE            16567
    lacks statutory authority for the payments to the DSIs, which
    the Cooperative claims are “subsidies” and barred by the gov-
    erning statutes. BPA’s counter to both of these challenges is
    that its ability to monetize the DSI contracts is consistent with
    (1) its statutory mandate to sell power “with a view to encour-
    aging the widest possible diversified use of electric power at
    the lowest possible rates to consumers consistent with sound
    business principles,” see § 838g, and (2) its general authority
    to enter into contracts, see §§ 832a(f), 839f(a). We conclude
    that BPA’s interpretation of its governing statutes is reason-
    able and that, under appropriate circumstances, BPA may
    lawfully monetize its energy contracts. Such circumstances,
    however, do not exist here. We therefore also hold that BPA’s
    decision to monetize the aluminum DSI contracts amounts to
    an impermissible subsidy of those companies’ operations.
    Because, by its own admission, BPA is not obligated to sell
    power to the DSIs, its decision to sell power voluntarily at a
    rate below what it is statutorily required to offer (i.e., the IP
    rate) and below what it could receive on the open market vio-
    lates its statutory mandate to act in accordance with “sound
    business principles.” See § 838g.
    1.   Authority to Monetize Generally
    [10] Other than a provision related to the sale of energy to
    IOUs, see § 839c(c), there is no explicit statutory language in
    the NWPA that either allows or prohibits BPA from monetiz-
    ing energy contracts. To the extent that “the relevant statutes
    are silent on the salient issue,” we “defer to [BPA]’s [statu-
    tory] construction . . . unless that construction is unreason-
    able.” Ass’n of Pub. Agency Customers, 
    126 F.3d at 1169
    .
    [11] BPA’s explanation of its purported authority to “mon-
    etize” the sale of power — that is, to provide the DSIs with
    money in lieu of physical power — begins with the observa-
    tion that the agency has broad authority under its governing
    statutes to enter into contracts. See §§ 832a(f) (“Subject only
    to the provisions of this chapter [of the Project Act], [BPA]
    16568       PACIFIC NORTHWEST GENERATING v. DOE
    is authorized to enter into such contracts, agreements, and
    arrangements . . . upon such terms and conditions and in such
    manner as [it] may deem necessary.”), 839f(a) (“Subject to
    the provisions of this chapter [of the NWPA], the [BPA] is
    authorized to contract in accordance with [§ 832a(f)]”). Con-
    gress also vested BPA with the authority to acquire power,
    including purchasing energy on the open market, if needed to
    meet its contractual obligations. See § 839d(a)(2)(A) (“[T]he
    Administrator shall acquire . . . sufficient resources — (A) to
    meet his contractual obligations . . . .”); see also Alcoa, 467
    U.S. at 386 & n.5 (noting that the NWPA, for the first time,
    provided BPA with the “authority to own, construct, or pur-
    chase the output or capability of electricity generating
    plants”) (emphasis added). And, as already discussed, BPA is
    authorized by statute to contract with the DSIs for the sale of
    power, and must offer to do so at the IP rate. See Part III.B,
    supra. Because BPA has the statutory authority to sell power
    to the DSIs at valid contract rates and to purchase at market
    rates the power needed to service those contracts, it is reason-
    able for BPA to conclude that it has the authority to simply
    pay the difference between the valid contract rates and a
    higher market rate, if any. If BPA places no cap on the
    amount of its monetary payments to the customer, the cus-
    tomer should be largely indifferent between the payment and
    the delivery of physical power. Moreover, as BPA asserts,
    monetization reduces its financial costs because it circum-
    vents the risk that a customer will default on payment after
    power is physically delivered. When BPA lowers its costs, all
    customers, including preferential customers, benefit. Thus,
    monetization, if utilized under appropriate circumstances, is
    also consistent with BPA’s mandate to maintain “the lowest
    possible rates to consumers consistent with sound business
    principles.” § 838g.
    Further, as BPA represents, monetization of energy con-
    tracts appears to be a common industry practice, confirming
    that the practice is not inherently inconsistent with “sound
    business practices.” BPA states that “[l]ong-term power sales
    PACIFIC NORTHWEST GENERATING v. DOE                   16569
    and exchange contracts frequently include provisions that spe-
    cifically provide the option to cash out an energy delivery
    under specific circumstances.” As evidence of this practice,
    BPA cites its decision to buy back energy obligations from
    customers, including DSI customers, during the west coast
    energy crisis of 2001. Neither Alcoa nor the Cooperative chal-
    lenges the existence of this general industry practice.
    [12] For the above reasons, we hold that BPA can monetize
    its energy contracts with the DSIs, so long as the decision to
    monetize is otherwise consistent with BPA’s statutory obliga-
    tions. See Portland Gen., 
    501 F.3d at 1036-37
     (holding that
    BPA’s statutory authority to enter into settlement agreements
    pursuant to section 2(f) of the Project Act is cabined by the
    agency’s other statutory obligations).
    2.   Monetization of Aluminum DSI Contracts
    [13] Despite our conclusion that BPA has, in some circum-
    stances, the statutory authority to monetize its contracts, we
    hold that monetization of the aluminum DSI contracts was
    improper. The decision to monetize embodied in the agree-
    ments violated other statutory obligations, namely, BPA’s
    mandate to provide “the lowest possible rates to consumers
    consistent with sound business principles.” § 838g. When it
    committed itself to the particular monetary benefit provisions
    in the DSI contracts, BPA, in effect, agreed to supply some
    power to the DSIs — although not as much as they wanted —
    at a rate that is below both the market rate and the IP rate and
    could be as low as the PF rate.34 See DSI Service ROD
    34
    The monetization provisions do not, of course, involve the actual sale
    of physical power by BPA to the DSIs. Those provisions, however, com-
    mit BPA to paying the DSIs the difference between the rate they pay for
    power on the open market and a rate denominated an FPS rate but essen-
    tially equivalent in amount to the PF rate, subject to the limitations dis-
    cussed at pp. 16528-29, supra. Assuming that power is readily available
    for purchase on the open market by the DSIs, the monetization provisions
    will therefore achieve a result functionally equivalent to the sale of power
    by BPA to the DSIs at the baseline rate used to calculate the monetary
    benefit.
    16570         PACIFIC NORTHWEST GENERATING v. DOE
    (acknowledging that the rates embodied in the monetization
    provisions would permit the DSIs to purchase power at a rate
    below the market and below the IP rate). BPA also concedes
    that its decision to sell power to the aluminum DSIs at below-
    market and below-IP rates will increase rates for its non-DSI
    customers. DSI Service ROD (“BPA is mindful that service
    to the DSIs will come at the expense of higher rates paid by
    its public preference customers . . . .”). Finally, by its own
    admission, BPA was not obligated to sell power to the DSIs,
    and was not obligated to offer a rate below the IP rate if it did
    sell them power. In essence, BPA has voluntarily agreed to
    forgo revenues by charging the DSIs a rate below what is
    authorized by statute (i.e., the IP rate) and below what is
    available on the open market. These foregone revenues result
    in higher rates for all other customers. This outcome is in
    apparent and direct conflict with BPA’s statutory mandate,
    see § 838g, and renders BPA’s decision to “monetize” the
    DSI contracts in an amount reflective of those underlying rate
    decisions — albeit a capped amount — highly suspect.
    BPA offers three rationales in an attempt to justify its deci-
    sion to utilize a below-market and below-IP rate as a base rate
    for calculating the DSIs’ monetary benefit. First, it asserts that
    offering the DSIs a subsidized rate furthers the agency’s man-
    date to “encourage the widest possible diversified use of elec-
    tric power.” See § 839g. Second, BPA suggests that the rate
    assumptions are consistent with its authority to market power,
    because the agency already sells power at below cost rates to
    IOUs under the “residential exchange program” mandated by
    the NWPA. See § 839c(c). Finally, BPA argues that its deci-
    sion was reasonable because providing aid to long-term cus-
    tomers is in its business interests. Each of these justification
    is flawed and therefore incapable of supporting BPA’s deci-
    sion to offer DSIs capped monetized power at a rate below
    both the IP rate and the market rate. We therefore hold that
    that decision was unreasonable.35
    35
    There are situations in which BPA’s decision to monetize its energy
    contracts with the DSIs would likely qualify as reasonable. For example,
    PACIFIC NORTHWEST GENERATING v. DOE                    16571
    BPA’s first argument — that helping the DSIs furthers its
    mandate to “encourage the widest diversified use of electric
    power” — does not justify a sale of power at below market
    or statutorily mandated rates. See § 838g. This explanation is
    undercut, first of all, by the fact that the subsidized rates are
    supplied to just three firms, all of which use electric power for
    the same industrial purpose — smelting aluminum. Thus, the
    payments do not encourage “diversified” use of electric
    power, but targeted use. Morever, because, as BPA acknowl-
    edges, its rates are “based upon the [BPA]’s total system
    costs,” § 839e(a)(2), a side-effect of the payments to the alu-
    minum DSIs will be an increase in the rates paid by a much
    larger set of customers — the businesses, industries, farms,
    and residences served by public utilities, electrical coopera-
    tives, and investor-owned utilities with BPA power.
    Common sense suggests that increasing these rates will
    cause consumers, overall, to employ electric power for nar-
    rower and less diverse uses. When the price of a particular
    source of energy goes up, uses of that energy that were afford-
    able or profitable at the old price tend to be less so at the new
    one. An increase in rates will lead at least some consumers to
    either restrict their usage or substitute another source of
    power.
    Furthermore, BPA’s conclusory claim that the contracts
    will facilitate the diversified use of power could justify almost
    if BPA entered into a contract with a DSI at the IP rate (which it is statu-
    torily authorized to do) in order to free up power to sell outside the Pacific
    Northwest, and the market rate for power exceeded the IP rate, the deci-
    sion to monetize would probably conform to “sound business principles.”
    In such a case, monetization would reduce the risk of a default by the DSI
    and would thereby lower BPA’s financial costs. Similarly, if BPA entered
    into a contract with a DSI at a valid contract rate (whether the market rate
    or the IP rate) and BPA’s costs to acquire power rose unexpectedly during
    the performance of the contract, exercising the option to monetize the now
    money-losing contract would likely be valid. This situation appears to
    have occurred during the west coast energy crisis, when BPA chose to
    monetize several contracts.
    16572         PACIFIC NORTHWEST GENERATING v. DOE
    any sale of power, including an agreement to give power
    away. Absent a specific explanation as to why sales to the
    DSIs on more favorable terms than required by statute or by
    market circumstances is necessary to diversify the use of
    power in the region, the agency’s argument is unpersuasive.
    BPA’s next contention, that the IOU residential exchange
    program supports its decision to offer the DSI below-cost
    rates, is likewise untenable. In fact, the program’s existence
    not only fails to support BPA’s position, it actually under-
    mines that position. Under the “residential exchange pro-
    gram,” BPA exchanges high-priced power generated by the
    IOUs for low-cost federal energy to be supplied to their resi-
    dential customers. See § 839c(c); Alcoa, 467 U.S. at 399.
    Rather than actually trade power with the IOUs, BPA simply
    pays the cost differential to the IOUs. See, e.g., Cent. Elec.
    Coop., Inc. v. BPA, 
    835 F.2d 199
    , 200-01 (9th Cir. 1987).
    But the exchange program is a specific exception that
    proves a general rule — and the rule is that Congress intended
    BPA to operate as a business selling power for profit, not as
    a charitable institution distributing “benefits.” See, e.g., Ass’n
    of Pub. Agency Customers, 
    126 F.3d at
    1171 (citing BPA’s
    “mandate to operate with a business-oriented philosophy”).
    As the Supreme Court has observed, “[b]ecause th[e]
    exchange program essentially requires BPA to trade its cheap
    power for more expensive power, it is obviously a money-
    losing program for BPA.” Alcoa, 467 U.S. at 399. In the case
    of the exchange program, Congress specifically directed BPA
    to conduct its operations in a manner that does not conform
    with the “sound business principles” that the agency is gener-
    ally required to follow. No such exception to § 838g’s statu-
    tory mandate applies here. By subsidizing the DSIs’ smelter
    operations beyond what it is obligated to do, BPA is simply
    giving away money.36
    36
    At oral argument, counsel for BPA conceded that “[i]t’s not Bonne-
    ville’s responsibility to ensure that [the DSIs] exist.”
    PACIFIC NORTHWEST GENERATING v. DOE                   16573
    There is another provision in the NWPA that authorizes
    BPA to make monetary payments to specific parties. See, e.g.,
    16 U.S.C. § 839e(m) (authorizing “annual impact aid pay-
    ments to the appropriate local governments within the region”
    affected by BPA power generation or transmission projects).
    But the DSIs are not among the entities to which any of these
    payments are authorized. See id. Again, the fact that Congress
    explicitly gave permission to BPA to provide subsidies to
    these other entities weighs against BPA’s claim that Congress
    implicitly authorized it to provide such subsidies as it chooses
    to the DSIs. Cf. Tang v. Reno, 
    77 F.3d 1194
    , 1197 (9th Cir.
    1996).37
    The NWPA also specifies certain circumstances in which
    BPA can sell power to the DSIs at a discounted rate. See 16
    U.S.C. § 839e(d) (authorizing a “special rate” for power sold
    to any DSI “using raw materials indigenous to the region as
    its primary resource”). But § 839e(d) makes clear that such
    discounts are only available in specific circumstances not
    present here.38
    Finally, BPA maintains that the decision to give the DSIs
    favorable rates of BPA’s choosing is authorized because
    37
    The inclusion of a provision for subsidies in the NWPA also counsels
    somewhat against our deferring to the agency’s interpretation of the stat-
    ute, as it suggests that the question of BPA’s authority to make such pay-
    ments is not one where “Congress has . . . left a void for [the] agency to
    fill.” Ass’n of Pub. Agency Customers, 
    126 F.3d at 1169
    .
    38
    There is no indication that the aluminum DSIs that are to receive the
    payments “us[e] raw material indigenous to the region as [their] primary
    resource.” § 839e(d)(1). The primary raw material used in aluminum
    smelting is bauxite, which is imported. Cf. In re Kaiser Aluminum &
    Chem. Co., 
    214 F.3d 586
    , 590 (5th Cir. 2000) (discussing use of imported
    bauxite in domestic aluminum production). And the legislative history of
    the subsection confirms that it was not the aluminum DSIs Congress had
    in mind when it adopted this provision. See H.R. Rep. No. 96-976, pt. 2,
    at 52-53 (1980) (“The Committee is aware of only one [DSI], the Hanna
    Nickel and Mining and Smelting Company[,] . . . which would meet the
    criteria of this paragraph.”).
    16574       PACIFIC NORTHWEST GENERATING v. DOE
    doing so “further[s] BPA’s business interests consistent with
    its public mission.” Ass’n of Pub. Agency Customers, 
    126 F.3d at 1171
    . This Court “defers to the [BPA]’s actions in fur-
    thering its business interests.” 
    Id. at 1171
    . Still, BPA fails to
    explain how the payments are consistent with its “mandate to
    operate with a business-oriented philosophy,” 
    id.,
     as it has
    identified no business interests forwarded by its actions. The
    agency cites its “historic relationship with the DSIs, the
    important role the DSIs played in the development of the [fed-
    eral power systems], and the importance to local economies
    of DSI jobs” as reasons for the payments. These justifications
    for simply giving a few of its customers nearly $300 million,
    however laudable, are simply not reflective of a “business-
    oriented philosophy,” nor do they “further [BPA’s] business
    interests.” 
    Id.
    As we made clear recently in another context, BPA’s gov-
    erning statutes restrain BPA’s activities even when, on a pure
    policy basis, those policies have much to recommend them.
    See Portland Gen., 
    501 F.3d at 1036-37
    . Applying this very
    basic principle, Portland General held that BPA’s general
    statutory authority to enter into settlement agreements under
    § 832a(f) of the NWPA does not allow BPA to avoid the
    requirements governing power sales to the IOUs simply by
    labeling such sales as “settlements.” 501 F.3d at 1030. Here,
    similarly, BPA’s authority to sell power to the DSIs does not
    mean that BPA may simply give money to the DSIs by calling
    the agreement a “power sale” with “monetized service bene-
    fits.” In Portland General, BPA’s actions violated the specific
    requirements of the REP; here they violate the agency’s gen-
    eral statutory mandate to operate like a business. In both
    cases, however, the lesson is the same: an agency cannot
    expand its mandate solely through creative use of nomencla-
    ture.
    [14] In sum, BPA has not advanced a “reasonable interpre-
    tation[ ] of its governing statutes” that supports its actions.
    Golden Nw. Aluminum Co., 501 F.3d at 1045. Nor has the
    PACIFIC NORTHWEST GENERATING v. DOE                  16575
    agency shown how offering the DSIs rates below the market
    rate and below what it is statutorily authorized to offer “fur-
    ther[s] BPA’s business interests consistent with its public mis-
    sion.” Ass’n of Pub. Agency Customers, 
    126 F.3d at 1171
    . We
    conclude that BPA’s decision to offer the subsidized rates to
    the DSIs and then monetize those rates is inconsistent with
    BPA’s statutory authority under the NWPA, and therefore
    hold that the monetization provisions of the aluminum con-
    tracts are invalid.
    D.    BPA’s Contract with Clallam to
    Supply Port Townsend
    Industrial Customers challenge BPA’s decision to supply
    Port Townsend with power on two related grounds. First,
    Industrial Customers argues that the rate applicable to the sale
    is impermissibly low because it is “not the DSI rate, . . . or
    the market price of electricity” and is instead “designed to
    closely mimic the low PF rate only available to preference
    customers.” Second, Industrial Customers contends that Port
    Townsend is a “new large single load” to which the agency’s
    New Resources (NR) rate, a rate higher than both the PF rate,
    the IP rate, and BPA’s forecasted market rate, applies. We
    agree with Industrial Customers that the Clallam/Port Town-
    send contract rate is invalid because it commits BPA to sell
    power to Port Townsend (through Clallam) at a rate below
    both the market rate and the IP rate. As a result of this hold-
    ing, we need not reach Industrial Customers’ additional argu-
    ment that the Port Townsend energy contract should be priced
    at BPA’s “New Resources” rate for “new large single loads,”
    rather than at the rate set in the contract.39
    39
    Although we do not decide the “new large single load” question, we
    note that BPA’s contract with Clallam to supply Port Townsend, as cur-
    rently structured, would likely not qualify as a “new large single load,”
    and BPA would therefore not be obligated to charge Clallam or Port
    Townsend the NR rate. Section 839a(13) defines a “new large single load”
    as one that increases the “power requirements” of a public utility such as
    16576          PACIFIC NORTHWEST GENERATING v. DOE
    [15] BPA’s contract with Clallam/Port Townsend suffers
    from the same central deficiency as BPA’s contracts with the
    aluminum DSIs. Namely, BPA, although under no obligation
    to supply Port Townsend with power, has nonetheless agreed
    to sell power to the paper company at a rate below both the
    market rate and the IP rate.40 The agency provides no unique
    Clallam, but does not supply a definition for the term “power require-
    ments.” BPA attempts to fill this gap by arguing that “power require-
    ments” refers to sales it is required to make to public utilities pursuant to
    § 839c(b). In light of § 839a(13)’s legislative history, we conclude that the
    agency’s interpretation is reasonable, and therefore entitled to deference.
    Congress’s intent in passing § 839a(13) was to deter DSI customers
    from cancelling their direct service contracts with BPA that were priced
    at the IP rate and, instead, purchasing their power at a lower rate from
    local public utilities served by BPA. See H.R. Rep. No. 96-976, pt. 2, at
    51. The fear was that, because BPA must serve the firm power require-
    ments of its public utility customers under § 839c(b) at the low PF rate,
    a sudden increase in those requirements due to strategic behavior by the
    DSIs could place financial and operating burdens on the agency. See id.
    In other words, the obligation imposed on BPA by § 839c(b) was the driv-
    ing force behind the “new large single load” provision. BPA’s interpreta-
    tion of “power requirements” as referring to its § 839c(b) obligation is
    therefore reasonable.
    In this case, BPA and Clallam structured their contract as a “surplus
    firm power” sale under § 839c(f), not as a firm power sale under
    § 839c(b). Clallam was not exercising its statutory entitlement to firm
    power at the PF rate, and BPA was under no obligation to enter into the
    contract. As a result, the BPA/Clallam contract does not appear to be the
    type of contract to which the preventative NR rate was intended to apply.
    40
    The Port Townsend sale is structured somewhat differently than the
    aluminum DSIs sales in that it involves two separate contracts, rather than
    a single contract. The first of the two contracts is an agreement between
    BPA and Clallam, the utility that serves Port Townsend, and provides for
    the sale of 17 annual aMW of power by BPA to Clallam at the PF rate plus
    a “typical industrial margin” of $0.57/MWh, for a total cost of approxi-
    mately $28/MWh. (For a discussion of why this rate, although calculated
    in a manner which appears to mimic the methodology BPA must follow
    when determining the IP rate, see § 839e(c), is not in fact equivalent to the
    IP rate, see note 28, supra.). Under the second contract, Clallam agreed to
    PACIFIC NORTHWEST GENERATING v. DOE                   16577
    reasons to explain why supplying Port Townsend with subsi-
    dized energy is consistent with “sound business principles.”
    See § 838g. Therefore, for the reasons discussed supra, Part
    III.C.2, BPA’s decision to subsidize Port Townsend’s energy
    rates is unreasonable because it is contrary to BPA’s statutory
    mandate.41 We therefore hold that the Clallam/Port Townsend
    contract is also invalid.42
    sell that power to Port Townsend at the BPA/Clallam rate plus “Other
    Costs” of approximately $0.94/MWh. Through the combined contracts,
    therefore, BPA has agreed to supply Port Townsend with 17 aMW of
    power at a rate approximately equal to $29/MWh. This rate is below both
    BPA’s forecasted market rate for 2007-2009 of $42/MWh, see DSI Ser-
    vice ROD, and the average IP rate for the year ending September 30, 2007
    of $45/MWh.
    41
    Even if we considered only the BPA/Clallam contract, our conclusion
    that the contract rates are invalid would not change. BPA concedes that
    the “sale of 17 aMW of . . . power to Clallam for service to Port Town-
    send” is a “discretionary sale,” and not one BPA is obligated to make to
    the public utility under § 839c(b). Because BPA admits it is not required
    to sell the power to Clallam — and no party argues that Clallam is entitled
    to the PF or any other cost-based rate under the circumstances involved
    here — the decision to sell power to Clallam at a below-market rate under
    the FPS rate schedule violates BPA’s mandate to operate according to
    “sound business principles” for the same reasons that a decision to offer
    the aluminum DSIs and Port Townsend a subsidized rate does. See Part
    III.C.2, supra.
    42
    BPA’s contract with Clallam/Port Townsend may also run afoul of
    BPA’s statutory requirement to first offer power to a DSI at the IP rate
    before selling it to the DSI under the FPS rate schedule. See Part III.B.2,
    supra. The record is somewhat ambiguous as to whether BPA offered Port
    Townsend the IP rate. In the DSI Service ROD, BPA indicated it would
    offer power to Port Townsend “under its market based rate schedule (or
    the IP rate if viable).” Yet, BPA ultimately applied an FPS rate to the
    Clallam/Port Townsend contract. It can therefore be presumed that BPA
    did not offer Port Townsend the IP rate. Should BPA decide to enter a
    future contract with Port Townsend at an FPS rate, it must first offer the
    company the IP rate.
    16578          PACIFIC NORTHWEST GENERATING v. DOE
    E.    Alcoa’s Discrimination Claim
    [16] Alcoa also challenges BPA’s contract with Clallam to
    supply power to Port Townsend on the ground that it discrimi-
    nates against other DSIs with regard to both price and method
    of service. This argument is without merit for at least two rea-
    sons. First, BPA’s governing statutes do not contain an anti-
    discrimination requirement that applies to the challenged con-
    tracts. Second, even if such a requirement existed, BPA’s
    decision to offer Port Townsend contract terms different from
    those it offered the aluminum DSIs was justified by Port
    Townsend’s unique characteristics, most notably its small
    size. We therefore deny this aspect of BPA’s petition.
    BPA’s primary argument is that § 832d(a), which requires
    BPA’s contracts with “any utility engaged in the sale of elec-
    tric energy to the general public” to “contain such terms and
    conditions . . . necessary . . . to insure that resale by such util-
    ity to the ultimate consumer shall be at rates which are rea-
    sonable and nondiscriminatory,” precludes BPA from treating
    Port Townsend differently from the aluminum DSIs. A plain
    reading of § 832d(a)’s statutory text — which we have not
    previously construed — indicates that its purpose is to prevent
    discrimination by a utility among its customers, not discrimi-
    nation by BPA between utilities and the DSIs, or even among
    DSIs. Although § 832d(a) may well forbid BPA from entering
    into a contract with Clallam that permits Clallam to discrimi-
    nate against the aluminum DSIs, the aluminum DSIs are not
    seeking service from Clallam. In short, the provision is inap-
    plicable here.43
    43
    Similarly off-base is Alcoa’s claim that BPA’s contract with Clallam
    is governed by the transmission line requirement contained in 16 U.S.C.
    § 825s (authorizing the Secretary of Energy “to construct or acquire . . .
    only such transmission lines and related facilities as may be necessary” to
    “make the power and energy generated at [federal] projects available in
    wholesale quantities for sale on fair and reasonable terms”). As we have
    noted previously, “that phrase refers to the acquisition and construction of
    PACIFIC NORTHWEST GENERATING v. DOE                   16579
    Alcoa’s second argument — that the NWPA defines DSIs
    as a single class of customers and therefore requires BPA to
    treat them all identically — is also unavailing. The NWPA
    does define and treat the DSIs as a common class for the pur-
    poses of allocating power and setting rates for power sales.
    See §§ 839a(8) (defining DSI); 839c(d)(4)(A) (defining “ex-
    isting” DSI); 839c(e)(1) (reallocating power which a customer
    does not require among others in same class); 839e(c)(1)(B)
    (establishing rates for sale of power to DSIs). And, as already
    discussed, the NWPA requires BPA to offer its DSI customers
    firm power at the IP rate before it offers those customers an
    FPS rate. But once a DSI refuses to buy power at the rate to
    which it is statutorily entitled (i.e., the IP rate), it has surren-
    dered the primary benefit that the class of DSI customers
    receives under the NWPA and becomes subject to the same
    treatment as any other in-region customer seeking to purchase
    surplus firm power. Perhaps more to the point, nothing in the
    NWPA suggests that BPA must treat members within the
    same customer class identically. The NWPA authorizes, but
    does not obligate, BPA to sell power to a DSI. See Part
    III.B.1, supra. BPA could therefore refuse to serve some of its
    DSIs altogether, while supplying the full power requirements
    of others.
    Lastly, even if there were some applicable nondiscrimina-
    tion requirement in BPA’s governing statutes — which, as we
    have explained, there is not — BPA’s different means for
    supplying the aluminum DSIs and Port Townsend would not
    be discriminatory. As BPA points out, the considerations
    associated with serving Port Townsend with 17 aMW of
    physical power are different from the considerations associ-
    transmission facilities,” S. Cal. Edison Co. v. Jura, 
    909 F.2d 339
    , 343 n.6
    (9th Cir. 1990), but does not constrain BPA’s setting of rates for the power
    it sells once these facilities have been acquired or built. See 
    id. at 344
    (holding that 16 U.S.C. § 825s does not impose a “substantive nondiscrim-
    ination standard for BPA ratemaking”).
    16580          PACIFIC NORTHWEST GENERATING v. DOE
    ated with serving the DSIs with 560 aMW. The latter would
    expose the agency to much greater risk from fluctuation in
    energy prices and default by the DSIs.
    For all of these reasons, we deny this portion of Alcoa’s
    petition.
    F.   Damages Waiver in Aluminum DSI Contracts
    The final issue the Cooperative raises is the enforceability
    of a damages waiver provision that appears in each of the alu-
    minum DSI contracts. See, e.g., Alcoa Contract (“In the event
    the Ninth Circuit Court of Appeals or other court of compe-
    tent jurisdiction issues a final order that declares or renders
    this Agreement void or otherwise unenforceable, no Party
    shall be entitled to any damages or restitution of any nature.”).44
    The Cooperative argues that the contracts are void ab initio,
    thereby invalidating the waiver provisions. Unless BPA is
    able to recoup the payments already made to the DSIs, the
    Cooperative asserts, the Cooperative’s members will be stuck
    with the bill, as the agency will have to recover these costs
    through higher rates. See 
    16 U.S.C. § 839
    (g).
    BPA’s contracts with the DSIs, however, each contain a
    severability clause, which states that “[i]f any term of this
    Agreement is found to be invalid by a court of competent
    jurisdiction then . . . . [a]ll other terms shall remain in force
    unless that term is determined not to be severable from all
    other provisions of this Agreement . . . .” The contracts pro-
    vide for an alternative mode of performance by BPA, delivery
    of physical power, beginning in FY 2010. The validity of this
    aspect of the contract is not ripe for review at this time
    because BPA has not yet exercised its option to deliver physi-
    cal power, nor has it defined the terms that would govern a
    physical power sale. So the monetized service benefit provi-
    44
    The corresponding waiver provision in the Clallam contract bars only
    Clallam, not BPA, from recovering damages.
    PACIFIC NORTHWEST GENERATING v. DOE           16581
    sions of the agreements are, at least potentially, severable
    from the agreement as a whole, leaving a possibly valid
    option, the sale of physical power at an as-yet unspecified
    rate.
    In addition, the record does not reveal how BPA believes
    the damages waiver provision should be construed and, in
    particular, what effect it is to have if a contract is only par-
    tially invalidated. In the Supplemental ROD, BPA rejected as
    “unreasonable under the circumstances” a proposal by the
    Cooperative that the contracts with the aluminum DSIs
    include a provision “requiring the [DSIs] to refund payments
    in the event the Ninth Circuit holds that the contracts are
    void.” (emphasis added). The Agency’s reasoning was that
    even if “the contracts are held void (so that no contract ever
    existed as a matter of law) and the payments are ‘illegal,’ ” it
    would be inequitable to require restitution, because
    the companies will have little realistic prospect of
    operating their smelters . . . [y]et they may, at their
    own risk and expense, have made commitments with
    respect to operating their facilities, including making
    market power purchases, in anticipation of benefits
    being available.
    The actual contract language and factual circumstances
    here are significantly different from the proposal BPA
    rejected in the Supplemental ROD. First, invalidating the pay-
    ments does not necessarily foreclose the DSIs’ “prospect[s] of
    operating their smelters.” We do not hold that the contracts
    are void “as if no[ne] . . . ever existed.” Instead, we affirm the
    authority of BPA to sell physical power to the DSIs,
    § 839c(d), at a valid rate.
    [17] Second, the question of contractual interpretation
    before us is whether, if the agreements are partially invali-
    dated, BPA is permitted to seek restitution, not whether it is
    “requir[ed]” to do so. Whether BPA intended to retain the
    16582       PACIFIC NORTHWEST GENERATING v. DOE
    flexibility to seek or forgo repayment, depending on (a) the
    DSIs’ “commitments with respect to operating their facili-
    ties,” and (b) BPA’s interest in still making sales of physical
    power to them, is an issue the agency did not address in the
    Supplemental ROD. Because, “[f]rom the record before us,
    we cannot determine BPA’s likely course of action,” we
    remand to BPA to determine in the first instance the applica-
    bility and construction of the severability clause, the damage
    waiver, and the physical power sale option in light of our
    holdings here. Pub. Util. Dist. No. 1 v. BPA, 
    506 F.3d 1145
    ,
    1154 (9th Cir. 2007).
    [18] Finally, the Cooperative’s allegation that the waiver
    provision, if valid, will result in higher rates for non-DSI cus-
    tomers is not ripe for adjudication at this time. Until FERC
    approves the relevant PF rate schedule, this court lacks juris-
    diction to review the Cooperative’s claim. See Ass’n of Pub.
    Agency Customers, 
    126 F.3d at 1179
    ; Pub. Utils. Comm’n of
    the State of Cal., 
    814 F.2d at 561
    ; Pub. Utils. Comm’r of Ore-
    gon, 
    767 F.2d at 629
     (“If FERC fails to correct any defects in
    the methodology [which affected rate-setting], redress is
    available in the court of appeals,” where “any . . . cognizable
    challenges will be fully reviewable . . . .”).
    IV.   Conclusions
    We GRANT the Cooperative’s and Industrial Customers’
    petitions as to the challenges they bring regarding BPA’s stat-
    utory authority to offer the aluminum DSIs and Port Town-
    send (through Clallam) energy at rates below both the IP rate
    and the market rate, and REMAND to the agency for determi-
    nation of the applicability of the agreements’ severability and
    damage waiver provisions in light of our holdings.
    We GRANT Alcoa’s petition as to its challenge to BPA’s
    refusal to offer the aluminum DSIs the amount of physical
    power requested at a rate established under § 839e(c) prior to
    PACIFIC NORTHWEST GENERATING v. DOE            16583
    offering them a market-based rate or selling the power outside
    the region.
    We DISMISS the Cooperative and Industrial Customers’
    petitions as to their challenges to BPA’s allocation of costs
    incurred under the aluminum DSI and Port Townsend con-
    tracts to the agency’s power rates, as both premature and
    moot in light of our invalidation of those contracts in pertinent
    part.
    We otherwise DENY the petitions of Alcoa, the Coopera-
    tive, and Industrial Customers.
    PETITIONS GRANTED IN PART, DENIED IN PART,
    AND DISMISSED IN PART.
