AGUA MANSA POWER PLANT, a 61 MW Natural Gas power plant in San Bernardino County, California. Operated by E I COLTON LLC, commissioned 2003.
How AGUA MANSA POWER PLANT compares
With 61 MW of capacity, AGUA MANSA POWER PLANT ranks 217th among the 874 operating power plants Bywatts maps in California and 79th of the 190 operating Natural Gas plants in the state. It accounts for about 0.2% of California's operating Natural Gas capacity and under 0.1% of all operating capacity in the state. Nationally it is the 768th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2003, it is older than 51% of the 859 operating California plants with a recorded commissioning year. It shares San Bernardino County with 64 other operating plants, including MOUNTAINVIEW GENERATING STATION and HIGH DESERT POWER PLANT.
EIA-860 lists 1 generator at the site with 61 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 8.8 GWh in 2024 (a 1.7% capacity factor).
