`
`The transition to competitive wholesale power markets .... 6
`
`PJM provides power through competitive,
`wholesale power markets .................................................. 8
`
`C.
`
`PJM’s Tariff sets forth rules governing its
`administration of the capacity auction ...................................... 11
`
`D. Certain resources did not offer capacity into the 2024/2025
`auction, threatening an unnecessary price increase for southern
`Delaware consumers ................................................................ 12
`
`II.
`
`PJM files, and FERC accepts, a proposed change to its Tariff rules to
`address non-offering resources in a given capacity auction ................ 14
`
`SUMMARY OF ARGUMENT ..................................................................... 18
`
`ARGUMENT .............................................................................................. 22
`
`I.
`
`Standard of review ............................................................................ 22
`
`II.
`
`FERC’s orders accepting PJM’s Tariff revisions are lawful under the
`filed-rate doctrine and rule against retroactive ratemaking ................ 24

`A.

`
`C.
`
`D.
`
`E.
`
`F.
`
`PJM’s application of the Tariff Amendment to calculate the
`2024/2025 auction clearing price and to award capacity
`commitments was prospective because it did not alter the past
`legal consequences of past actions ........................................... 27
`
`Contrary to Petitioners’ assumptions, FERC reasonably
`concluded that PJM determined the 2024/2025 auction clearing
`price for the first time after the Tariff
`Amendment took effect ............................................................ 34
`
`1.
`
`2.
`
`3.
`
`Petitioners’ argument that PJM ran the optimization
`algorithm before the Tariff Amendment took
`effect is forfeited ............................................................. 36
`
`PJM may run the optimization algorithm multiple times,
`meaning a subsequent iteration does not retroactively
`override a prior run ......................................................... 37
`
`Running the algorithm is necessary, not sufficient, to
`determining the auction clearing price ............................ 40
`
`The Commission reasonably found that the Tariff Amendment is
`consistent with the Tariff provisions governing the posting and
`use of the LDA Reliability Requirement ................................... 47
`
`The Commission addressed Petitioners’ concern that PJM’s
`Tariff Amendment upset their s
`ettled expectations ................................................................... 52
`
`Intervenor-Petitioners’ argument, contrary to Petitioners’ own,
`is both forfeited and incorrect .................................................. 53
`
`Petitioners misstate FERC’s interpretation of the filed-rate
`doctrine and expand the doctrine beyond its limits ................... 55
`
`III. The Commission reasonably concluded that PJM’s Tariff Amendment
`is “just and reasonable,” after accounting for Petitioners’ asserted
`settled expectations .......................................................................... 57

`
`The Commission balanced Petitioners’ settled expectations
`against the benefits of accepting the Tariff Amendment ........... 59
`
`The Commission acted consistent with its case-by-case approach

`
`On Petitions for Review
`of Orders of the
`Federal Energy Regulatory Commission
`
`BRIEF FOR RESPONDENT
`FEDERAL ENERGY REGULATORY COMMISSION
`
`INTRODUCTION
`
`
`
`
`
`
`
`
`The Federal Power Act entrusts the Federal Energy Regulatory
`
`Commission (“Commission” or “FERC”) with “protect[ing] consumers from
`
`excessive rates and charges.” NextEra Energy Res., LLC v. FERC, 898 F.3d
`
`14, 21 (D.C. Cir. 2018) (cleaned up). Electric utilities’ rates must be “just
`
`and reasonable” such that they are high enough to ensure a reliable electric
`
`supply without over-billing ratepayers. See id. at 20; 16 U.S.C. §824d(a).
`
`This case involves a challenge to Commission orders that prevented a
`
`
`
`
`
`
`
`Case: 23-1778 Document: 75 Page: 15 Date Filed: 11/13/2023
`
`projected rate increase of more than four times what is necessary to ensure
`
`grid reliability.
`
`
`
`The Nation’s interstate electric grid is divided into geographic regions.
`
`In many of these regions, the grid is managed by a FERC-regulated regional
`
`transmission organization, hereafter termed a “wholesale market operator.”
`
`PJM Interconnection, L.L.C. is one such operator. Its territory spans 13
`
`States and the District of Columbia. To ensure a reliable electric supply at
`
`competitive prices, PJM holds an auction to secure electric power capacity
`
`that is adequate to meet projected consumer demand.
`
`The auction is really a request for capacity offerings. Electric
`
`generators (power plants), many of which are represented by Petitioners,1
`
`submit a price they are willing to receive to commit their resources to
`
`providing electric energy to the grid. PJM then matches these capacity offers
`
`against a curve that represents future demand for electricity. After an
`
`administrative review of the results, and after making necessary
`
`adjustments, PJM posts a clearing price for the capacity auction. All
`
`
`Constellation Energy Generation, LLC (“Constellation”), Electric
`1
`Power Supply Association (“EPSA”), NRG Business Marketing LLC
`(“NRG”), and PJM Power Providers Group (“P3”).
`
` 2
`
`
`
`Case: 23-1778 Document: 75 Page: 16 Date Filed: 11/13/2023
`
`resources that clear receive the clearing price, in exchange for committing to
`
`supply a specified amount of electricity when needed.
`
`The matter on review involves a PJM capacity auction (the
`
`“2024/2025 auction”) to secure electric capacity for the year commencing
`
`June 1, 2024 (the “delivery year”). PJM accepted capacity offers from
`
`December 7, 2022 through December 13, 2022. After the auction window
`
`closed but before PJM posted the clearing price, PJM discovered an anomaly:
`
`Not all the generation resources it expected to place offers in southern
`
`Delaware actually did place offers. That risked warping the auction results
`
`for that area because it meant one of the inputs (the Locational Deliverability
`
`Area (“LDA”) Reliability Requirement) PJM used to develop the auction
`
`demand curve for southern Delaware included generation resources that did
`
`not participate. Had PJM completed the auction under the then-in-effect
`
`demand curve, consumers would have incurred a surcharge, PJM projected,
`
`of approximately $100 million.
`
`At the relevant time, PJM’s Tariff allowed it to adjust a problematic
`
`LDA Reliability Requirement under certain conditions. On December 23,
`
`2022, PJM filed with the Commission an amendment to its Tariff (the
`
`“Tariff Amendment”) to add one more condition to the list: If planned
`
` 3
`
`
`
`Case: 23-1778 Document: 75 Page: 17 Date Filed: 11/13/2023
`
`resources that PJM expects to place capacity offers do not do so, and the
`
`addition of those resources materially affects the LDA Reliability
`
`Requirement, then PJM will adjust the Requirement to exclude those
`
`resources. It would then calculate the clearing price based on the adjusted
`
`version. On February 21, 2023, the Commission granted PJM’s request, and
`
`six days later PJM posted the clearing price for the 2024/2025 capacity
`
`auction.

`
`STATEMENT OF ISSUES
`
`Did the Commission’s approval of PJM’s Tariff Amendment comply
`
`with the filed-rate doctrine and rule against retroactive ratemaking,
`
`where those principles require a utility like PJM to apply its Tariff
`
`rules that are on file with the Commission, and where PJM applied
`
`the rules on file—the Tariff Amendment—to determine the
`
`2024/2025 capacity auction clearing price and auction
`
`participants’ capacity commitments?
`
`II. Did the Commission reasonably conclude, after balancing
`
`consumers’ interest in not paying an unnecessary surcharge against
`
`Petitioners’ expectation that the pre-amended 2024/2025 capacity
`
` 4
`
`
`
`Case: 23-1778 Document: 75 Page: 18 Date Filed: 11/13/2023
`
`auction rules would control the auction outcome, that it was “just
`
`and reasonable” to accept PJM’s Tariff Amendment?
`
`STATEMENT OF RELATED CASES AND PROCEEDINGS
`
`
`
`
`This case has not previously been before this Court and the
`
`Commission is not aware of any other related case or proceeding.
`
`STATEMENT OF FACTS
`
`I. Background
`
`A.
`
`The Federal Power Act
`
`
`
`
`
`
`
`Section 201 of the Federal Power Act, 16 U.S.C. §824, gives the
`
`Commission exclusive jurisdiction over the rates, terms, and conditions of
`
`service for the transmission and sale at wholesale of electric energy in
`
`interstate commerce. See FERC v. EPSA, 577 U.S. 260, 264–266 (2016).
`
`Under Section 205, §824d(a)–(b), all rates related to the transmission
`
`or sale of electric energy, and all related rules and regulations, must be “just
`
`and reasonable” and not “undu[ly] preferen[tial].” Further, the rates a utility
`
`charges must be on file with the Commission and publicly available.
`
`§824d(c).
`
`Under Section 206, §824e(a), if the Commission finds, on its own
`
`initiative or upon a third-party complaint, that an existing rate, or a rule,
`
` 5
`
`
`
`Case: 23-1778 Document: 75 Page: 19 Date Filed: 11/13/2023
`
`regulation, or practice affecting such rate, is “unjust, unreasonable, unduly
`
`discriminatory or preferential,” it must set a new just and reasonable rate, see
`
`FERC v. EPSA, 577 U.S. at 266, but may do so only prospectively, Old
`
`Dominion Elec. Coop. v. FERC, 892 F.3d 1223, 1226–1227 (D.C. Cir. 2018).
`
`B. Overview of wholesale electric power markets
`
`1.
`
`The transition to competitive wholesale power markets
`
`
`
`
`
`Traditionally, wholesale rates for electricity were primarily set on an
`
`individualized, cost-of-service basis. Morgan Stanley Cap. Grp. Inc. v. Pub.
`
`Util. Dist. No. 1 of Snohomish Cty., 554 U.S. 527, 532 (2008). That changed
`
`in 1996 with FERC Order 888 and in 1999 with FERC Order 2000, which
`
`normalized market-based rates. N.J. Bd. of Pub. Utils. v. FERC, 744 F.3d 74,
`
`81 (3d Cir. 2014) (“New Jersey”); Midwest ISO Transmission Owners v.
`
`FERC, 373 F.3d 1361, 1363–1364 (D.C. Cir. 2004). Among other things,
`
`both orders encouraged electric transmission owners to divest control of their
`
`transmission facilities and turn over operations to a wholesale market
`
`operator. Id. These market operators “are ‘public utilities’ under the
`
`[Federal Power Act], and are thus subject to FERC’s regulation.” New
`
`Jersey, 744 F.3d at 81. Taken together, FERC Orders 888 and 2000 sought
`
`to leverage market forces to promote competition in wholesale sales of
`
` 6
`
`
`
`Case: 23-1778 Document: 75 Page: 20 Date Filed: 11/13/2023
`
`electricity. New York v. FERC, 535 U.S. 1, 11 (2002); New Jersey, 744 F.3d
`
`at 82.

`
`PJM provides power through competitive, wholesale power
`markets
`
`
`
`PJM Interconnection, L.L.C. is one of several wholesale market
`
`operators. See Figure 1, supra. Its footprint is large, covering part or all of 13
`
`States and the District of Columbia. New Jersey, 744 F.3d at 82. “One of
`
`PJM’s primary responsibilities as system operator is to ensure that there is a
`
`sufficient amount of electrical capacity within its system to provide reliable
`
`electricity to its consumers during periods of peak demand. ‘Capacity’ is not
`
`electricity itself but the ability to produce it when necessary.” Id. (cleaned
`
`up). Demand for electric energy is termed “load,” and local utilities that sell
`
`electricity to end-use consumers are deemed, in industry vernacular,
`
`“load-serving entities.” Id.
`
`PJM administers “a ‘capacity auction’ to ensure the availability of an
`
`adequate supply of power at some point in the future.” Hughes v. Talen
`
`Energy Mktg., LLC, 578 U.S. 150, 155 (2016). The capacity auction relevant
`
`to this case is the Base Residual Auction. As pertinent here, the auction’s
`
`primary purpose is to ensure “that [PJM’s] system will be reliable.” New
`
`Jersey, 744 F.3d at 84. A higher auction clearing price encourages the
`
`construction of new resources, whereas a lower price signals a need for the
`
` 8
`
`
`
`Case: 23-1778 Document: 75 Page: 22 Date Filed: 11/13/2023
`
`“retirement of existing high-cost generators.” Hughes, 578 U.S. at 156.
`
`Consumers ultimately bear the cost of the clearing price through the rates
`
`they pay their local load-serving entities. See New Jersey, 744 F.3d at 84.
`
`PJM conducts the auction to secure capacity sufficient to meet
`
`projected system demand for a full year (the delivery year). Id. at 82, 84.
`
`The delivery year generally takes place three years in the future.2 Id.
`
`Capacity sellers (i.e., capacity resources like electric generators or entities
`
`that have contracted for capacity) offer their capacity into the auction at the
`
`minimum price they are willing to receive. Id. at 83. PJM clears the auction
`
`by accepting offers until there is sufficient capacity to satisfy PJM’s
`
`projected demand for each sub-region within PJM—an approach called the
`
`Reliability Pricing Model. Id. at 83–84. These sub-regions are called
`
`Locational Deliverability Areas. Id. All offers that clear the auction receive
`
`the clearing price relevant to a particular LDA, which may differ from PJM’s
`
`regionwide clearing price. See id.; Hughes, 578 U.S. at 156 n.2; PJM Tariff,
`
`Attach. DD, §§5.11(e); 6.2(b), A57–A58, A68. In the matter on review, the
`
`capacity auction for the Delmarva Power & Light–South LDA
`
`
`Market reforms in recent years have resulted in a compressed schedule.

`
`(“Delmarva”)—which covers southern Delaware—commenced on December
`
`7, 2022, for the delivery year beginning June 1, 2024. PJM Interconnection,
`
`L.L.C., 184 FERC ¶61,055, PP 4, 10 (July 27, 2023), JA___–___, ___
`
`(“Rehearing Order”). Because the delivery year spans June 1, 2024 to May
`
`31, 2025, the auction is hereafter termed the “2024/2025 auction.”
`
`The shape of the capacity demand curve for each LDA, and for the PJM
`
`region as a whole, depends on certain inputs. One such input is the LDA
`
`Reliability Requirement, PJM Interconnection, L.L.C., 182 FERC ¶61,109,
`
`P 3 (Feb. 21, 2023), JA___–___ (“Initial Order”), which “is the amount of
`
`capacity that must be produced to meet peak demand, including a reserve
`
`margin,” Del. Div. of Pub. Advocate v. FERC, 3 F.4th 461, 463–464 (D.C. Cir.
`
`2021). Specifically, the Requirement represents the internal generation
`
`capacity within an LDA plus the amount of capacity that must be imported
`
`into the LDA to maintain grid reliability. Rehearing Order P 6, JA___. This
`
`imported capacity is called the Capacity Emergency Transfer Objective
`
`(“CETO”). Id.

`
`C.
`
`PJM’s Tariff sets forth rules governing its administration of the
`capacity auction
`
`Under the filed-rate doctrine, a utility like PJM may apply only its
`
`
`
`Tariff rules that are on file with the Commission. Okla. Gas & Elec. Co. v.
`
`FERC, 11 F.4th 821, 829 (D.C. Cir. 2021). At the time PJM commenced the
`
`2024/2025 auction, its capacity auction rules prescribed the following:
`o “The parameters of the [LDA demand curve] will be established prior to
`
`the conduct of the Base Residual Auction for a Delivery Year and will be
`
`used for such Base Residual Auction.” Tariff, Attach. DD,
`
`§5.10(a)(vi)(A), A53.
`o “[PJM] shall determine the … [LDA] Reliability Requirement … on or
`
`before February 1, prior to the conduct of the Base Residual Auction[.]”
`
`§5.10(a)(vi)(B), A53.
`o “[P]rior to conducting the Base Residual Auction,” “PJM will post …
`
`[t]he [LDA] Reliability Requirement” for a given LDA. §5.11(a), (a)(v),
`
`A56.
`o After generator capacity offers are received and the offer window closes,
`
`see §§5.6, 5.6.1, 5.8, A35–A37, A40–A41, “[PJM] shall employ an
`
`optimization algorithm … to evaluate the Sell Offers and other inputs to
`
` 11
`
`
`
`Case: 23-1778 Document: 75 Page: 25 Date Filed: 11/13/2023
`
`such auction to determine the Sell Offers that clear such auction.” §5.12,
`
`A59. The algorithm “shall be applied” in a way that “minimiz[es] the
`
`cost of satisfying the reliability requirement[].” §5.12(a), A59–A60.
`o After running the optimization algorithm, “[PJM] shall calculate a
`
`clearing price” for the auction. §5.14(a), A67. “PJM will post” the
`
`clearing price “as soon … as possible” after making any necessary
`
`adjustments to, for example, the LDA Reliability Requirement. §5.11(e),
`
`A57–A58. At the time PJM commenced the 2024/2025 auction, PJM
`
`could adjust the LDA Reliability Requirement to, for example, reflect
`
`Price Responsive Demand,3 correct errors, and address
`
`lower-than-expected clearing of energy efficiency resources. Rehearing
`
`Order P 58 n.185, JA___.
`
`D. Certain resources did not offer capacity into the 2024/2025
`auction, threatening an unnecessary price increase for southern
`Delaware consumers
`
`In conducting the 2024/2025 capacity auction, PJM complied with its
`
`
`
`auction rules by timely posting the LDA Reliability Requirement for
`
`
`Price Responsive Demand refers to end-use consumers capable of
`3
`curtailing their energy use within a short timeframe in response to variable
`energy prices. See Initial Order P 17 n.58, JA___.

`
`Case: 23-1778 Document: 75 Page: 26 Date Filed: 11/13/2023
`
`Delmarva (on August 29, 2022), and timely opening the auction window (on
`
`December 7, 2022) and closing it (on December 13, 2022). Id. PP 10, 35,
`
`JA___–___, ___–___. But after the offer window closed, PJM discovered
`
`an anomaly. Its LDA Reliability Requirement counted as capacity resources,
`
`for purposes of the 2024/2025 delivery year, planned facilities that were to
`
`be built and placed into service prior to June 1, 2024. Id. PP 6, 8, JA___,
`
`___. That is, PJM expected these new resources to be available to provide
`
`electric generation capacity beginning June 1. Yet “a significant amount” of
`
`those resources “did not offer [their capacit
