FERC Seeks Comment on Implementation of Dynamic Line Ratings for Transmission Facilities

On August 8, 2025, the Federal Energy Regulatory Commission (FERC) issued an enforcement order in Skye MS, LLC (Skye) and levied a $45,000 civil penalty on an intrastate pipeline operator in Mississippi, resolving an investigation into the operator’s violations of section 311 (Section 311) of the Natural Gas Policy Act (NGPA). FERC faulted the operator for providing a Section 311 transportation service without timely filing a Statement of Operating Conditions (SOC) and obtaining FERC’s approval for the transportation rates. Section 311 permits intrastate pipelines to transport interstate gas “on behalf of” interstate pipelines without becoming subject to FERC’s more extensive Natural Gas Act (NGA) jurisdiction, but requires the intrastate pipeline to have an SOC stating the rates and terms and conditions of service on file with FERC within 30 days of providing the interstate service. Under the NGPA, Section 311 rates must be “fair and equitable” and approved by FERC. In Skye, FERC stated that the operator began providing Section 311 service on certain pipeline segments in Mississippi in May 2023, following their acquisition from another Section 311 operator, but did not file an SOC with FERC until April 2025. The order ties the penalty to the approximately two-year delay between commencement of the Section 311 service and the SOC filing date. The pipeline operator was also ordered to provide an annual compliance report and to abide by additional verification requirements related to the filing of its FERC Form No. 549D, the Quarterly Transportation & Storage Report for Intrastate Natural Gas and Hinshaw Pipelines.

In Sierra Club v. FERC, No. 24-1199 (D.C. Cir. Aug. 1, 2025), the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) upheld the Federal Energy Regulatory Commission’s (FERC) approval of a 1,000-foot natural gas pipeline segment crossing the United States-Mexico border (the Border Pipeline) under section 3 of the Natural Gas Act (NGA), rejecting environmental groups’ challenges that FERC improperly limited its analysis under both the NGA and the National Environmental Policy Act (NEPA), as related to a 155-mile intrastate “Connector Pipeline” constructed upstream of the Border Pipeline in Texas.

On July 15, 2025, the Federal Energy Regulatory Commission (FERC or Commission) issued an order¹ proposing to eliminate the soft price cap of $1,000 per megawatt-hour (MWh) for bilateral spot sales in the Western Electricity Coordinating Council (WECC) that was implemented following the California energy crisis. If adopted, the Commission’s proposal would eliminate the requirement that sellers make a filing with FERC cost justifying spot market sales in excess of the soft price cap, which have become increasingly common in recent years as market conditions have continued to tighten throughout the West. Eliminating the WECC soft price cap would provide sellers that make sales during periods when prices exceed the cap greater certainty that their sales will not be second guessed after the fact.

On June 4–5, 2025, the Federal Energy Regulatory Commission (FERC or Commission) hosted a commissioner-led technical conference to discuss resource adequacy challenges facing regional transmission organizations and independent system operators (RTO). The conference is a response to the growing concern that multiple RTO regions across the country may not have sufficient supply available in the coming years to meet demand due to resource retirements, the pace of new generation entry and higher load growth arising from the construction of data centers and reindustrialization.

On June 4, 2025, the U.S. Department of Transportation’s (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) announced revisions to its procedures for pipeline safety enforcement actions. The changes, outlined in two new policy memoranda from PHMSA’s Office of the Chief Counsel (PHC), aim to enhance due process protections for pipeline operators by clarifying how civil penalties are calculated and expanding the disclosure of agency records in enforcement proceedings.

On May 19, 2025, the Department of Energy (DOE) finalized its 2024 LNG Export Study: Energy, Economic and Environmental Assessment of U.S. LNG Exports (the 2024 Study) through the release of a Response to Comments on the 2024 Study. The Response to Comments concludes that the 2024 Study, as augmented through public comments submitted on or before March 20, 2025, supporting a finding that liquefied natural gas (LNG) exports serve the public interest. With the comment process complete, DOE will move forward with final orders on pending applications to export LNG to non-free trade agreement (non-FTA) countries.

On Thursday, May 15, the Senate Commerce, Science & Transportation Subcommittee on Surface Transportation, Freight, Pipelines and Safety held a hearing titled, “Pipeline Safety Reauthorization: Ensuring the Safe and Efficient Movement of American Energy.” The hearing examined legislative priorities for reauthorizing the Pipeline and Hazardous Materials Safety Administration (PHMSA).
