On April 29, 2025, FERC partially granted rehearing in the case of Cometa Energia, S.A. de C.V. (“Saavi”) against the California Independent System Operator Corporation (“CAISO”), finding a provision of CAISO’s Business Practice Manual for Reliability Requirements (“Business Practice Manual”) must be included in CAISO’s tariff under the “rule of reason,” as the provision significantly impacts rates and services. In its underlying complaint, Saavi argued that CAISO unlawfully terminated the deliverability status of its 181.5 megawatt generating unit (“Project”). In its rehearing order, FERC agreed that under the “rule of reason” CAISO should have reflected the deliverability status provision of its Business Practice Manual in its tariff, but FERC declined to reinstate the Project’s deliverability status citing concerns over reduced resource adequacy for other generating units.

FERC Again Rejects Co-Located Load Increase Proposal at Nuclear Facility
By Alex Spratley & Jill Drum on
On April 10, 2025, FERC addressed arguments on rehearing that clarified, but did not modify the outcome of, a November 1, 2024, order (“Rejection Order”) rejecting PJM Interconnection, L.L.C.’s (“PJM”) proposal to increase the co-located data center load at a Susquehanna Nuclear, LLC (“Susquehanna”) nuclear generating facility. FERC again found that PJM’s amended Interconnection Service Agreement’s (“ISA”) non-conforming provisions were not necessary deviations from the pro forma ISA. However, FERC did clarify that the Rejection Order did not prevent other entities from filing non-conforming ISAs to address issues relating to co-located data center load.
FERC Chief Accountant Proposes to Modify Transferability of Income Tax Credits
By S. Jennifer Panahi & Ben Duwve on
On September 12, 2024, FERC’s Chief Accountant issued a notice of proposed accounting release (“NOPAR”) to modify the transferability of income tax credits (“ITCs”) related to certain energy projects under the Inflation Reduction Act of 2022 (“IRA”), which allows entities to monetize such ITCs via transfers to independent third parties…
FERC Holds Workshop on Innovations & Efficiencies in Generator Interconnection Process, Seeks Comments
On September 10 and 11, 2024, FERC staff held a two-day workshop at its headquarters in Washington, DC on opportunities to further refine the generator interconnection queue process. Panelists and FERC staff discussed potential enhancements to transmission planning and processing interconnection requests over the course of six panels on discrete…
Court Vacates FERC “Soft” Cap Refund Order Issued After 2020 California Heat Wave
By Troutman Pepper Locke, Jill Drum & Miles Kiger on
On July 9, 2024, the United States Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) vacated orders issued by the FERC that required six wholesale power sellers (the “Sellers”) to issue refunds to customers for power sales made above FERC’s “soft” price cap during the 2020 heatwave in California. The court held that FERC “should have conducted [a] Mobile-Sierra analysis prior to ordering refunds,” and therefore remanded the orders so that FERC could “change its refund analysis for above-cap sales going forward.”
SCOTUS Overrules Chevron Deference in 6-3 Ruling
By Jill Drum & Russell Kooistra on
On June 28, 2024, the United States Supreme Court (“Supreme Court”) overruled its prior decision in Chevron U.S.A. v. Natural Resources Defense Council (“Chevron”) in a 6-3 vote in Loper Bright Enterprises et al. v. Raimondo, Secretary of Commerce, et al. (“Loper Bright”). The Chevron doctrine has required federal courts to defer to administrative agencies’ interpretations of statutes the agency administers when the underlying statute is ambiguous. Under the Loper Bright ruling, federal courts will not defer to administrative agencies in interpreting ambiguous statutes and instead must exercise their judgment in determining whether the agency acted within its statutory authority. The decision will likely have a substantial impact on both regulated industries and federal agencies such as FERC.
FERC Dismisses Lackawanna Complaint Against PJM Seeking “Stability Limit”-Related Lost Opportunity Costs
On May 23, 2024, FERC issued an Order denying Lackawanna Energy Center LLC’s (“Lackawanna”) complaint against PJM Interconnection, L.L.C. (“PJM”) alleging that PJM failed to reimburse Lackawanna for lost opportunity costs (“LOC”) incurred following allegedly improper curtailment orders from PJM during a 2023 transmission line outage. Lackawanna argued that PJM’s curtailment of its generation output violated the Federal Power Act and the PJM Tariff, which typically allow for LOC payments when generator output is reduced due to transmission constraints or reliability issues. FERC dismissed all claims raised in the complaint.
Third Circuit Upholds PJM Capacity Market Change but Prevents Retroactive Application
On March 12, 2024, the U.S. Court of Appeals for the Third Circuit upheld a prospective rule change to PJM Interconnection, L.L.C.’s (“PJM”) annual capacity auction but struck down attempts by PJM and FERC to apply the rule change to the ongoing auction held in December 2022. Although the rule change permits PJM to adjust the Locational Deliverability Area (“LDA”) Reliability Requirement downward to reflect the lack of participation in the December 2022 auction by certain resources to correct for distortions to the auction results, the Third Circuit held that FERC could not permit the change to go into effect in the middle of an ongoing auction.
Troutman Pepper Summary of FERC Order No. 2023-A on Generator Interconnections
Executive Summary
On March 21, the Federal Energy Regulatory Commission (FERC or the Commission) issued Order No. 2023-A (Final Rule), which reaffirmed aspects of Order No. 2023 — the Commission’s landmark order updating its generator interconnection procedures. As detailed further in this summary, the Commission largely upheld Order No. 2023, including some of the more controversial aspects of the order, such as penalties and the transmission capacity “heat map,” and provided further clarity on other aspects.
FERC Accepts PJM Capacity Market Revisions to Locational Deliverability Area Reliability Requirement, Sparks Strong Dissent from Commissioner Danly
By S. Jennifer Panahi & Katherine O'Konski on
On February 21, 2023, FERC accepted PJM Interconnection, L.L.C.’s (“PJM”) proposed tariff revisions governing the Locational Deliverability Area Reliability Requirement (“LDA Reliability Requirement”) calculation, effective December 24, 2022, and applicable to the 2024/2025 Base Residual Auction (“BRA”), which was in progress at the time that PJM submitted its filing. Specifically, FERC accepted tariff changes that would allow PJM, during the BRA process, to exclude Planned Generation Capacity Resources from the LDA Reliability Requirement calculation if the addition of such resources materially increases the reliability requirement and such resources do not participate in the capacity auction. The February 21 Order also dismissed as moot a complaint filed by PJM challenging the justness and reasonableness of the existing LDA Reliability Requirement. Finally, the February 21 Order stated that FERC would soon convene a forum to examine the functioning of the PJM capacity market. Commissioner Danly issued a separate dissenting statement.
