Oklahoma's generating fleet in context
Oklahoma has 36.7 gigawatts of nameplate capacity across 151 plants, ranking 10th among the 50 states and DC. This is capacity — what the equipment could produce running flat out — not the generation it actually produces over a year, which depends on how many hours each plant runs and at what fraction of full power.
Natural gas dominates the fleet at 49.7% of capacity with 34 plants, while wind provides 36.7% across 70 installations. Coal, hydro, solar, and battery storage together account for the remainder, with coal at 5.3%, hydro at 2.9%, solar at 2.5%, and battery storage also at 2.5%. The five largest plants by capacity are all natural gas stations: Muskogee at 1,716 megawatts, Seminole at 1,701 megawatts, Northeastern at 1,478 megawatts, Redbud Power Plant at 1,434 megawatts, and Kiamichi Energy Facility at 1,370 megawatts. The fleet spans from Cushing, first online in June 1936, to Mayes County Solar, which entered service in August 2026.
