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.

On March 30, 2025, FERC approved revisions to Southwest Power Pool, Inc.’s (“SPP”) Open Access Transmission Tariff (“Tariff”) and Governing Documents to allow nine entities (“Expansion Members”) in the Western Interconnection to join SPP’s Regional Transmission Organization (“RTO”) as transmission-owning members (“RTO West”), on the condition that SPP submit compliance…

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.

On February 20, 2025, FERC denied Great Basin Transmission, LLC’s (“Great Basin”) request for two transmission incentives for Great Basin’s Southwest Intertie Project-North Transmission Line and associated upgrades to Great Basin’s existing One Nevada Transmission Line (together, the “Project”). FERC found that Great Basin did not demonstrate that the Project…

On November 21, 2024, FERC issued an Order partially accepting NorthWestern Energy Corporation’s (“NorthWestern”) compliance filing, effective July 10, 2024.  FERC found that NorthWestern’s filing partially complies with the requirements of Order Nos. 2023 and 2023-A and directed NorthWestern to submit a further compliance filing within 60 days.

On November 21, 2024, FERC issued Order No. 1920-A, which modified Order No. 1920 to expand the states’ roles in long-term transmission planning and clarified requirements for such planning as set forth in Order No. 1920. FERC made changes in three broad areas, amongst many other modifications: (1) expanding the role of state entities in the transmission planning process, (2) requiring transmission providers to create additional transmission planning scenarios to inform implementation of cost allocation methods upon the request of state entities, and (3) removing the requirement for transmission providers to include corporate financial commitments in Factor Category Seven when developing long-term transmission planning scenarios.

On December 5, 2024, the U.S. Court of Appeals for the Third Circuit heard oral arguments in Transource Pennsylvania LLC v. Steven M. Defrank, et.al.

On July 25, 2024, FERC issued an order granting in part and denying in part a complaint raised by American Municipal Power, Inc., the People’s Counsel for the District of Columbia, and the PJM Industrial Customer Coalition (collectively, “Complainants”) against PJM Interconnection, L.L.C. (“PJM”) arguing, principally, that PJM violated Schedule 6 of the PJM Operating Agreement by failing to execute Designated Entity Agreements in all situations with each “Designated Entity,” or the entity designated to build transmission projects that PJM selects in the PJM Regional Transmission Expansion Plan (“RTEP”). FERC also granted in part and denied in part a separate request by PJM under section 206 of the Federal Power Act to revise Schedule 6 of the PJM Operating Agreement (the “PJM 206 Filing”) governing the RTEP process and associated requirements for Designated Entity Agreements. FERC established paper hearing procedures to develop a record to determine PJM’s responsibilities concerning Designated Entity Agreements for certain RTEP projects already in process and whether remedial actions are required to address the Operating Agreement violations.
