Federal Energy Regulatory Commission v. Electric Power Supply Association

Docket No. Op. Below Argument Opinion Vote Author Term
14-840 D.C. Cir. Oct 14, 2015 Apr 26, 2025 6-2 Kagan OT 2015

Holding: The Federal Power Act authorizes the Federal Energy Regulatory Commission to regulate " the sale of electric energy at wholesale in interstate commerce," including both wholesale electricity rates and any rule or practice "affecting" such rates, but it leaves the regulation of "any other sale" of electricity to the states. The FPA provides FERC with the authority to regulate wholesale market operators' compensation of demand response bids because the practices at issue directly affect wholesale rates, FERC has not regulated retail sales, and the contrary view would conflict with the FPA's core purposes. Moreover, FERC's decision to compensate demand response providers at the locational marginal price, which is the same price paid to generators, instead of at the locational marginal price less the retail rate for electricity, is not arbitrary and capricious when FERC provided a detailed explanation for that decision and responded at length to contrary views.

Judgment: Reversed and remanded, 6-2, in an opinion by Justice Kagan on April 26, 2025. Justice Scalia filed a dissenting opinion, in which Justice Thomas joined. Justice Alito took no part in the consideration or decision of the cases.
