SEMINOLE, a 1,724 MW Natural Gas power plant in Seminole County, Oklahoma. Operated by OKLAHOMA GAS & ELECTRIC CO, commissioned 1971.
How SEMINOLE compares
With 1,724 MW of capacity, SEMINOLE ranks 2nd among the 73 operating power plants Bywatts maps in Oklahoma and is the largest of the 23 operating Natural Gas plants in the state. It accounts for about 12% of Oklahoma's operating Natural Gas capacity and 6.9% of all operating capacity in the state. Nationally it is the 24th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1971, it is older than 66% of the 72 operating Oklahoma plants with a recorded commissioning year. Its operator, OKLAHOMA GAS & ELECTRIC CO, runs 10 operating plants in Oklahoma totaling 8,515 MW.
EIA-860 lists 3 generators at the site with 1,701 MW of nameplate capacity, all natural gas steam turbine technology. Net generation was 2,375 GWh in 2024 (a 16% capacity factor), up 59% from 2022. Its generators came online between 1971 and 1975.

Weather peril exposure
SEMINOLE is a 1,724 MW natural gas power plant in Seminole County, OK, operated by OKLAHOMA GAS & ELECTRIC CO, commissioned in 1971. Seminole County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 5.0 of 5 at the 99th national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 99th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
