It accounts for about 1.0% of Oklahoma's operating Natural Gas capacity and 0.5% of all operating capacity in the state. Nationally it is the 625th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1966, it is older than 75% of the 72 operating Oklahoma plants with a recorded commissioning year. Its operator, OKLAHOMA MUNICIPAL POWER AUTHORITY, runs 3 operating plants in Oklahoma totaling 171 MW. It shares Kay County with 3 other operating plants, including NEXTERA-BLACKWELL WIND, LLC and KAW HYDRO.
EIA-860 lists 3 generators at the site with 134 MW of nameplate capacity, mainly natural gas fired combined cycle technology. Net generation was 22.6 GWh in 2024 (a 1.9% capacity factor). Its generators came online between 1966 and 2003.

Weather peril exposure
PONCA CITY is a 134 MW natural gas power plant in Kay County, OK, operated by OKLAHOMA MUNICIPAL POWER AUTHORITY, commissioned in 1966. Kay County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.7 of 5 at the 92nd national percentile. Tornado is the leading peril, rated Relatively High by FEMA at the 96th 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.
