US Other Power Plants

The United States has 1,540 plants in this fuel category holding 49,003 megawatts of nameplate capacity — what the equipment could produce running flat out, not what it generated. This represents 3.5% of all US generating capacity. The fleet spans geothermal, biomass, petroleum, other gases, and pumped storage, a diverse portfolio spread across all 50 states and DC. However, capacity concentrates in a handful of states: just nine states hold half the total. California leads with 4,529 megawatts in 150 plants, accounting for 9.2% of this fuel type nationally, though it represents only 4.1% of California's own total capacity. New York follows with 3,897 megawatts across 95 plants, and Connecticut, Louisiana, Massachusetts, and Florida each hold between 2,730 and 3,104 megawatts.

The largest individual plants are Oswego Harbor Power in New York at 1,804 megawatts, Brame Energy Center in Louisiana at 1,707 megawatts, and Canal in Massachusetts at 1,495 megawatts. Geysers Unit 5-20 in California reaches 1,236 megawatts, while William F Wyman Hybrid in Maine holds 863 megawatts. The fleet's age spans more than a century: Woodland Pulp, LLC in Maine came online in June 1906, while the newest addition, Public Works Generation in Kansas, began operating in August 2026. This diversity of locations, fuel types, and ages reflects the varied role these technologies play in the national generating mix.
