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.
Order No. 1920-B Affirms FERC’s Long-Term Transmission Planning and Cost Allocation Rule
On April 11, 2025, FERC issued Order No. 1920-B, which clarified and maintained key requirements from Order No. 1920-A regarding long-term transmission planning and cost allocation. FERC clarified that transmission providers are not obligated to plan for the long-term needs of unenrolled non-jurisdictional transmission providers, but voluntary arrangements are allowed. The order also upheld the requirement for transmission providers to include Relevant State Entities’ agreed-upon cost allocation methods in their compliance filings. Additionally, FERC sustained the consultation requirement with Relevant State Entities before amending cost allocation methods. Lastly, FERC declined to expand the definition of “Relevant State Entity” and rejected certain rehearing requests as procedurally barred. Overall, FERC explained that Order No. 1920-B reinforces the importance of long-term, forward-looking, and comprehensive transmission planning and cost allocation processes to meet the demands of the modern transmission grid. The order was approved by four Commissioners, with Commissioner See not participating.
FERC Denies Complaint Over $23 Million in Network Upgrade Costs
On March 20, 2025, FERC denied Ponderosa Power, LLC’s (“Ponderosa”) complaint alleging that NorthWestern Corporation’s (“NorthWestern”) application of its large generator interconnection procedures (“LGIP”) was unjust and unreasonable or unduly discriminatory or preferential. The dispute centered around NorthWestern’s requirement for Ponderosa to fund approximately $23 million in network upgrades to accommodate the interconnection of its 70 MW wind-powered generation facility located in Musselshell County, Montana (“Project”).
Petitioners Seek FERC Clarification Regarding Jurisdiction Over Proposed Storage-Based Transmission Project Between Puerto Rico and the United States
On February 10, 2025, Pluvia LLC (“Pluvia”) filed a petition for a declaratory order, asking FERC to clarify its jurisdiction to issue a preliminary permit for the construction, operation, and maintenance of transmission lines and other facilities to develop wholesale interstate transmission of electricity between Puerto Rico and the mainland United States. In its petition, Pluvia proposes to purchase electricity from the interstate transmission system on the U.S. mainland, store energy in Storage As Transmission-Only Assets (“SATOA”) or other storage devices, and ship the stored energy as sea cargo to Puerto Rico. Pluvia explains that, if approved by FERC, its proposal would establish an alternative to undersea cables as a basis for FERC’s Federal Power Act (“FPA”) jurisdiction in Puerto Rico.
Court Finds FERC Appropriately Evaluated Decision to Retain Dams in License Surrender
On January 14, 2025, the U.S. Court of Appeals for the D.C. Circuit (“D.C. Circuit”) held that FERC complied with the National Environmental Policy Act (“NEPA”) in approving the surrender of a hydroelectric project license. The court found that FERC had adequately considered the alternative of dam removal and determined that keeping the dams in place outweighed any potential benefits to recreation, fisheries, and other environmental concerns. The case, American Whitewater v. FERC, involved a challenge to FERC’s license surrender decision regarding the Somersworth Hydroelectric Project (“Project”) on the Salmon Falls River, which spans the border between New Hampshire and Maine.
FERC Issues Nearly $1B Market Manipulation Penalty Regarding Alleged Energy Efficiency Projects
On December 16, 2024, the Federal Energy Regulatory Commission (“FERC”) directed American Efficient, LLC, its subsidiaries, and corporate parents (collectively, “American Efficient”) to show cause why American Efficient should not be found to have violated anti-manipulation rules. The order alleges that American Efficient engaged in a manipulative scheme to extract millions of dollars in capacity payments from Midcontinent Independent System Operator, Inc. (“MISO”) and PJM Interconnection, L.L.C. (“PJM”) for energy efficiency projects that did not actually reduce energy use. FERC also requested American Efficient to show cause why they should not disgorge over $253 million in unjust profits and pay a civil penalty of $722 million.

On November 21, 2024, the Federal Energy Regulatory Commission (“FERC”) issued a final rule establishing a categorical one-year “reasonable period of time” for certifying authorities to act on requests for water quality certification under section 401 of the Clean Water Act (“CWA”). The final rule also clarifies that all FERC authorizations “that have the potential to discharge into waters of the United States,” including hydropower exemptions, amendments, and surrenders, require either a section 401 water quality certification or waiver thereof.

Panelists and FERC staff discussed potential enhancements to transmission planning and processing interconnection requests over the course of six panels on discrete
D.C. Circuit Finds FERC Failed to Adequately Consider GHG Emissions of LNG Project
On July 16, 2024, the United States Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) found that FERC failed to adequately consider a liquefied natural gas (“LNG”) project’s greenhouse gas (“GHG”) emissions and failed to properly assess the cumulative effects of the LNG project’s nitrogen dioxide (“NO2”) emissions. While the D.C. Circuit remanded to FERC for further consideration, it did so without vacatur.
