On November 17, 2025, FERC accepted the Midcontinent Independent System Operator, Inc.’s (MISO) proposed revisions to its Open Access Transmission Tariff (OATT) to modify real power testing requirements for Demand Resources. MISO specifically proposed more stringent requirements for Demand Resources seeking waiver of performing real power tests and real power tests for Demand Resources using a firm service level baseline. FERC accepted the proposed revisions as just and reasonable, finding the proposed revisions standardize testing procedures for Demand Resources.

On November 24, 2025, the U.S. District Court for the Middle District of North Carolina denied American Efficient LLC’s (American Efficient) preliminary injunction seeking to halt FERC’s civil enforcement proceedings for alleged market manipulation and tariff violations. American Efficient argued that FERC’s process violated the Seventh Amendment and Article III of the U.S. Constitution by denying its right to a jury trial in an Article III court. The Court held that the Federal Power Act’s (FPA) scheme—allowing FERC to assess a penalty but requiring the government to obtain a de novo jury trial in federal court before any penalty can be enforced—satisfies requirements under the Constitution.

On October 28, 2025, the U.S. Court of Appeals for the Fifth Circuit (Fifth Circuit) denied several petitions for review of FERC’s authorization of Gas Transmission NW, LLC’s (GTN) GTN Xpress compressor expansion project (Project).  Specifically, the Fifth Circuit (1) denied GTN’s petition for review challenging FERC’s denial of a…

On October 1, 2025, the Federal Energy Regulatory Commission issued a final rule revising 53 regulations to include conditional sunset provision in response to the April 2025 Executive Order titled “Zero-Based Regulatory Budgeting to Unleash American Energy.” FERC, along with nine other agencies, was required to establish one-year…

On September 9, 2025, the United States Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) on remand from the U.S. Supreme Court upheld FERC’s order granting Broadview Solar, LLC’s (“Broadview”) hybrid solar and battery project qualifying facility (“QF”) status based on FERC’s interpretation of the Public Utility Regulatory Policies Act of 1978 (“PURPA”). Specifically, even without the benefit of Chevron deference (discussed below), the D.C. Circuit reaffirmed FERC’s interpretation that PURPA’s 80 MW statutory size limitation should be applied using the capacity a QF can “send out” to the grid, even if the facilities have a higher aggregate generating capacity.

On August 29, 2025, FERC issued three orders accepting tariff revisions proposed by PacifiCorp and Portland General Electric (“PGE”) to enable both utility’s participation in the California Independent System Operator Corporation’s (“CAISO”) Extended Day-Ahead Market (“EDAM”) and accepting CAISO’s proposed tariff revisions which modify the EDAM’s allocation of congestion revenues. The three orders issued by FERC clear the way for PacifiCorp and PGE, the first two entities to file tariff revisions to participate in the EDAM, to enter the market in 2026.

On May 22, 2025, the U.S. Court of Appeals for the Fifth Circuit (“Fifth Circuit”) addressed a dispute between ANR Pipeline Company (“ANR”) and FERC. The case centered on the interpretation of ANR’s tariff and whether it required shippers to deliver and take gas simultaneously, even for short-notice shipments. The Fifth Circuit denied ANR Pipeline Company’s petition for review, affirming FERC’s decision that ANR’s tariff did not require simultaneous delivery for short-notice shipments. The court found the tariff ambiguous and emphasized ANR’s longstanding practice of not requiring simultaneous delivery, which supported FERC’s position.

On May 14, 2025, FERC accepted Southwest Power Pool, Inc.’s (“SPP”) proposed revisions to its Open Access Transmission Tariff (“OATT”) to modify its high priority transmission study planning process. SPP argued these changes will allow transmission studies to better address transmission issues identified by stakeholders by expanding the scope of such studies to allow for considerations beyond economic benefits and costs, such as short-circuit and dynamic stability. FERC accepted the proposed OATT revisions as just and reasonable, finding the revised process to satisfy the goals of FERC Order No. 890 and allow SPP’s studies to address the specific needs of stakeholders.

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.
