Before HOLMES, Chief Judge, HARTZ, Circuit Judge, and GARCIA *, District Judge.

*

The Honorable Matthew L. Garcia, U.S. District Judge, District of New Mexico, sitting by designation.

HARTZ, Circuit Judge.

Plaintiffs are Kansas residential consumers of natural gas. They purchase gas from local distributors who in turn purchase gas from interstate wholesalers. They have sued the wholesalers for violating the Kansas Consumer Protection Act (KCPA), K.S.A. §§ 50-623–643, alleging that the wholesalers profiteered during a winter-weather emergency that brought arctic temperatures to the State, causing unprecedented increases in state-regulated retail natural-gas prices. The rates charged by these wholesalers are regulated by the Federal Energy Regulatory Commission (FERC) under the Natural Gas Act (NGA), 15 U.S.C. §§ 717–717z.

The issue before us is whether the NGA preempts Plaintiffs’ claims against the wholesalers. We hold that it does. As the Supreme Court has said, it is “well settled” that “Congress occupied the field of matters relating to wholesale sales and transportation of natural gas in interstate commerce.” Schneidewind v. ANR Pipeline Co., 485 U.S. 293, 305 (1988). These lawsuits directly target such sales. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm the district court’s judgment.

I. BACKGROUND This appeal arises from the consolidation of five class actions. Each action was brought by residential consumers within a distinct geographical region in Kansas— “with each region having its own natural gas distributor.” In re Winter Storm Uri Natural Gas Litig., 772 F. Supp. 3d 1246, 1251 (D. Kan. 2025). The regional distributors are Kansas Gas Service (KGS), Kansas Municipal Gas Agency (KMGA),
