Tenth Circuit Avoids Circuit Split in PURPA Dispute, Revives Federal Suit

Jun 30, 2021

Reading Time : 1 min

Passed by Congress in 1978 to promote renewable energy resources, PURPA directs the Federal Energy Regulatory Commission (FERC) to promulgate rules prohibiting utilities from engaging in price discrimination against small generating facilities called Qualifying Facilities (QFs1) and further directs state public utility commissions to implement FERC’s rules.2

PURPA provides both a federal and state enforcement mechanism.3 Over the years, courts have settled on a distinction between “as-applied” and “as-implemented” challenges, with the former falling under state jurisdiction and the latter falling under federal jurisdiction. An “as-applied” claim involves an allegation that a state or utility’s implementation of PURPA is unlawful as applied to the complaining person or persons, while “as-implemented” claims contend that a state or utility failed to implement the FERC rule lawfully.

In this case, the city of Farmington imposed additional charges on electric customers who produce their own power. A group of rooftop solar owners challenged the ordinance in federal district court in New Mexico, arguing that it violated FERC’s antiprice discrimination rules implementing PURPA.

Departing from the as-applied versus as-implemented framework, the district court had determined that it lacked jurisdiction over the dispute because federal courts can only address whether a state “outright fail[ed] to implement a rule,” not whether the implementation was consistent with the FERC rule. Only state courts, according to the district court, have jurisdiction to ensure that a state or utility’s procedures actually comply with FERC’s regulations. If upheld on appeal, this interpretation of PURPA would have created a circuit split.

In Monday’s ruling, the 10th Circuit reversed. Looking primarily at the plain meaning of the word “implement,” the 10th Circuit reasoned that “it seems to us a non sequitur to claim that a utility can ‘implement’ a rule by issuing a regulation that is inconsistent with that rule.” Accordingly, the 10th Circuit reversed the district court’s judgment and remanded for further proceedings. On remand, the district court will evaluate the merits of the plaintiffs’ complaint regarding price discrimination.

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.
