Oklahoma's generating fleet in context
Oklahoma's generating fleet holds 36.4 gigawatts of nameplate capacity as of May 2026, ranking 10th among the 51 states and territories. This is capacity — what the equipment could produce running flat out — not generation: a megawatt of solar and a megawatt of natural gas appear identical here and produce vastly different amounts of electricity over a year.
Natural gas leads the fleet at 46.8% of capacity across 33 plants, followed closely by wind at 37.1% spread across 70 installations. Coal provides 8.6%, while hydro, battery storage, and solar account for 3%, 2.6%, and 1.6% respectively. The five largest plants are all natural gas facilities: Muskogee at 1,716 megawatts, Seminole (OK) 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 Huckleberry Solar, which came online in May 2026. The 147 plants tracked include backup generators below one megawatt, so the count does not reflect the size of the fleet — capacity is the measure that matters.
