On June 20, 2025, FERC approved Southwest Power Pool, Inc.’s (SPP) revisions to its Western Energy Imbalance Service (WEIS) tariff to allow a participating balancing authority to initiate a market hold due to reliability concerns and to specify how SPP will settle the market in the event of such a market hold. FERC found that the revisions will allow participating balancing authorities to timely respond to reliability-based events while avoiding disruptions to the WEIS market.
FERC Reaffirms MISO Interconnection Queue Cap on Rehearing
On May 27, 2025, FERC addressed arguments raised on rehearing of a January 30, 2025 order, which accepted the Midcontinent Independent System Operator, Inc.’s (“MISO”) proposal to modify its generator interconnection study process by implementing a queue cap and exemptions to that cap (the “Queue Cap Order”). In doing so, FERC reaffirmed that MISO’s proposed queue cap and exemptions align with Order No. 2003’s independent entity variations for regional transmission organizations and independent system operators.
FERC Accepts SPP’s Tariff Revisions Regarding Distribution of Make-Whole Payments for Self-Committed Resources
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.
FERC Accepts SPP’s Tariff Revisions Incorporating a Mark-to-Auction Mechanism for SPP’s Transmission Congestion Rights Market
On March 20, 2025, FERC approved Southwest Power Pool, Inc.’s (“SPP”) tariff revisions to incorporate a mark-to-auction collateral requirement for SPP’s Transmission Congestion Rights (“TCR”) market. In doing so, FERC found the revisions will mitigate market risk caused by market participants’ declining TCR values. However, the Commission declined SPP’s request to terminate the related ongoing show cause proceeding because the proposed tariff does not fully address the Commission’s concerns.
FERC Institutes Show Cause Proceeding on Co-Location Issues in PJM
On February 20, 2025, FERC found that the PJM Interconnection, L.L.C. (“PJM”) Open Access Transmission Tariff (“OATT”) appears to be unjust and unreasonable because it does not address with clarity or consistency the rates, terms, and conditions of service that apply to co-location arrangements and therefore directed PJM to show cause as to why the OATT, the Amended and Restated Operating Agreement of PJM, and Reliability Assurance Agreement Among Load Serving Entities in the PJM region (collectively, “Tariffs”) are just and reasonable or explain what changes to the Tariffs would remedy FERC’s concerns regarding co-location arrangements. In a separate order issued on February 20, 2025, FERC also rejected a proposal from certain Exelon transmission-owning utilities (“Exelon Companies”) to revise their transmission rate schedules attached to the PJM OATT to clarify that co-located load that is synchronized to the grid must be designated as network load or receive point-to-point transmission service.
FERC Accepts NYISO’s Proposal Regarding their 2025-2029 Demand Curve Reset
On January 28, 2025, FERC accepted the New York Independent System Operator, Inc.’s (“NYISO”) proposed revisions to its Market Administration and Control Area Services Tariff (“Services Tariff”). The revisions define the demand curves in the Installed Capacity (“ICAP”) Market for the 2025/2026 Capability Year and implement a quadrennial process, known as the Demand Curve reset (“DCR”), which outlines the methodologies and inputs for subsequent annual updates to the ICAP Demand Curves for the 2026/2027, 2027/2028, and 2028/2029 Capability Years.
D.C. Circuit Upholds FERC Order Requiring Stingray to Restore Service Before Abandoning Damaged Pipeline

(“Stingray”) to abandon a portion of its pipeline system on the condition that before doing so, Stingray either restore service or obtain a shipper agreement that the damaged pipeline segment remain out of service.
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
Eighth Circuit Applies FERC’s Filed Rate Doctrine to Reject Allegations that SPP Breached an Oral Contract Made During Winter Storm Uri
On August 5, 2024, the United States Court of Appeals for the Eighth Circuit (“Eighth Circuit”) denied Associated Electric Cooperative, Inc.’s (“AECI”) petition for review of a Federal Energy Regulatory Commission (“FERC”) order upholding FERC’s decision to exercise primary jurisdiction over emergency energy sales between Southwest Power Pool, Inc. (“SPP”) and AECI during Winter Storm Uri and FERC’s decision that SPP properly compensated AECI pursuant to SPP’s Open Access Transmission Tariff (“Tariff”). The Eighth Circuit denied the AECI’s petition and upheld FERC’s determination that AECI was appropriately compensated according to the existing tariff rates filed with FERC and, accordingly, rejected AECI’s claims that SPP had breached an alleged oral contract with SPP personnel made during the storm.
FERC Approves NERC’s CIP Reliability Standard on Cyber Security
On May 23, 2024, FERC approved the North American Electric Reliability Corporation’s (“NERC”) proposed Critical Infrastructure Protection (“CIP”) Reliability Standard, CIP-012-2 (Cyber Security – Communications between Control Centers), which is intended to improve upon and expand existing reliability standards to mitigate risks posed by loss of availability of communication links and certain data transmitted between bulk electric system (“BES”) Control Centers. FERC also approved NERC’s associated implementation plan, violation risk factors and violation severity levels, and the retirement of Reliability Standard CIP-012-1.
