On March 27, 2025, FERC approved Southwest Power Pool, Inc.’s (SPP) tariff revisions to remove the opportunity for resources that self-commit during the Reliability Unit Commitment Process (RUC) to avoid contributing to RUC system-wide make-whole payments. In doing so, FERC found the revisions are consistent with cost causation principles.

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.

FERC Approves MISO’s Use of Downward Sloping Demand Curve in 2025-2026 Planning Resource Auctions
On June 27, 2024, FERC accepted Midcontinent Independent System Operator Inc.’s (“MISO”) proposed tariff revisions that sought to implement a downward-sloping Reliability Based Demand Curve (“RBDC”) in the MISO Planning Resource Auction (“Auction”) beginning with the 2025/2026 Planning Year. FERC determined that MISO’s proposal is not only consistent with its acceptance of similar sloped curves in other Regional Transmission Owners/Independent System Operators capacity markets but that MISO’s proposal to adopt a downward-sloping RBDC will reduce volatility in Auction Clearing Prices, increase the stability of the capacity revenue stream over time, and render capacity investments less risky, thereby encouraging greater investment and at a lower financing cost.
Divided FERC Announces Much-Anticipated Transmission Rules
On May 13, 2024, the Commission announced two major transmission reform final rules: Building for the Future Through Electric Regional Transmission Planning and Cost Allocation (“Order No. 1920”) and Applications for Permits to Site Interstate Electric Transmission Facilities (“Order No. 1977”). Order No. 1920, which adopts specific requirements for how transmission providers must conduct long-term planning and allocate costs for regional transmission facilities, was the subject of significant debate at today’s meeting and only mustered two votes in support from the three sitting commissioners. The Commission unanimously approved Order No. 1977, which updates the process FERC will use in the limited circumstances in which it must exercise its authority over siting electric transmission lines, as directed by Congress in the Infrastructure Investment and Jobs Act of 2021 (“IIJA”).
Senate Introduces Bipartisan Legislation to Give FERC Retroactive Refund Authority Under Section 5 of the Natural Gas Act
On April 18, 2024, Senators Richard Blumenthal (D-CT) and Cindy Hyde-Smith (R-MS) introduced the Making Pipelines Accountable to Consumers and Taxpayers Act (“MPACT Act”) (S. 4171) that, if adopted, would grant FERC authority to order refunds under section 5 of the Natural Gas Act (“NGA”). Specifically, the MPACT Act amends section 5 of the NGA to give FERC authority to order a pipeline to issue retroactive refunds for charges FERC determines are unjust and unreasonable. The MPACT is intended to align FERC’s authority over the gas and electric industries and protect customers from unjust and unreasonable rates. At this time, a companion bill has not been introduced in the House of Representatives.
D.C. Circuit Upholds FERC Orders Granting Natural Gas Pipeline Companies’ Requests to Extend Project Deadlines
The United States Court of Appeals for the District of Columbia (“D.C. Circuit”) recently upheld two FERC orders granting natural gas pipeline developers’ requests to extend their construction deadlines. The D.C. Circuit denied the Sierra Club’s petitions for review of the extension orders because the court determined that FERC’s decisions were reasonable and adequately supported by the record. The D.C. Circuit further provided that FERC has broad discretion in determining whether a developer has demonstrated good cause for an extension and whether circumstances have changed enough to warrant revisiting FERC’s original findings.
