On April 10, 2025, FERC addressed arguments on rehearing that clarified, but did not modify the outcome of, a November 1, 2024, order (“Rejection Order”) rejecting PJM Interconnection, L.L.C.’s (“PJM”) proposal to increase the co-located data center load at a Susquehanna Nuclear, LLC (“Susquehanna”) nuclear generating facility. FERC again found that PJM’s amended Interconnection Service Agreement’s (“ISA”) non-conforming provisions were not necessary deviations from the pro forma ISA. However, FERC did clarify that the Rejection Order did not prevent other entities from filing non-conforming ISAs to address issues relating to co-located data center load.

On March 28, 2025, the D.C. Circuit denied a joint petition for review brought by Healthy Gulf and Sierra Club (together, “Petitioners”) challenging FERC’s grant of a certificate of public convenience and necessity (CPCN) to Driftwood Pipeline LLC (Driftwood) to construct two new natural gas pipelines (the “Project”) in southwestern Louisiana on grounds that FERC’s decision failed to comply with National Environmental Policy Act (NEPA) and the Natural Gas Act (NGA). The D.C. Circuit affirmed FERC’s analyses under NEPA and NGA but declined to address Driftwood’s claim that the Council on Environmental Quality’ (CEQ) regulations implementing NEPA, upon which Petitioners based their arguments, are not judicially enforceable because CEQ lacks authority to promulgate them.

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 January 24, 2025, FERC reinstated a certificate of public convenience and necessity (“CPCN”) for Transcontinental Gas Pipe Line Company’s (“Transco”) Regional Energy Access Expansion Project (“Project”) after the D.C. Circuit vacated and remanded FERC’s initial order certificating the Project (“Certificate Order”).

In January 2023, FERC granted Transco a CPCN

On November 1, 2024, FERC Commissioners led a technical conference at their headquarters in Washington, DC, on issues pertaining to co-locating large loads at generating facilities.

On November 1, 2024, the Federal Energy Regulatory Commission (“FERC”) rejected an amended Interconnection Service Agreement (“ISA”) filed by PJM Interconnection, L.L.C. (“PJM”) that proposed increasing the co-located data center load at a Susquehanna Nuclear, LLC (“Susquehanna”) nuclear generating facility. FERC held that PJM did not meet FERC’s “high burden”

On September 19, 2024, the Federal Energy Regulatory Commission (“FERC”) denied Enerwise Global Technologies, LLC’s (“CPower”) complaint against PJM Interconnection, LLC (“PJM”) alleging that PJM’s Open Access Transmission Tariff (“Tariff”) was unjust, unreasonable, and unduly discriminatory because it prevents Curtailment Service Providers (“CSP”) from using approved statistical sampling rules to
