CHOUTEAU, a 1,070 MW Natural Gas power plant in Mayes County, Oklahoma. Operated by ASSOCIATED ELECTRIC COOP, INC, commissioned 2000.
How CHOUTEAU compares
With 1,070 MW of capacity, CHOUTEAU ranks 10th among the 73 operating power plants Bywatts maps in Oklahoma and 6th of the 23 operating Natural Gas plants in the state. It accounts for about 7.7% of Oklahoma's operating Natural Gas capacity and 4.3% of all operating capacity in the state. Nationally it is the 81st-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2000, it is newer than 50% of the 72 operating Oklahoma plants with a recorded commissioning year. It shares Mayes County with 4 other operating plants, including GRDA COAL-FIRED COMPLEX and SALINA.
EIA-860 lists 6 generators at the site with 1,070 MW of nameplate capacity, all natural gas fired combined cycle technology. Net generation was 6,760 GWh in 2024 (a 72% capacity factor), up 28% from 2022. Its generators came online between 2000 and 2011.
