GRAPELAND PEAKER, a 50 MW Natural Gas power plant in San Bernardino County, California. Operated by SOUTHERN CALIFORNIA EDISON CO, commissioned 2007.
How GRAPELAND PEAKER compares
With 50 MW of capacity, GRAPELAND PEAKER ranks 249th among the 874 operating power plants Bywatts maps in California and 93rd of the 190 operating Natural Gas plants in the state. It accounts for about 0.1% of California's operating Natural Gas capacity and under 0.1% of all operating capacity in the state. Nationally it is the 807th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2007, it is newer than 51% of the 859 operating California plants with a recorded commissioning year. Its operator, SOUTHERN CALIFORNIA EDISON CO, runs 22 operating plants in California totaling 2,341 MW. It shares San Bernardino County with 64 other operating plants, including MOUNTAINVIEW GENERATING STATION and HIGH DESERT POWER PLANT.
EIA-860 lists 2 generators at the site with 60 MW of nameplate capacity, mainly natural gas fired combustion turbine technology (this page's HIFLD capacity figure is 50 MW). Net generation was 3.9 GWh in 2024 (a 0.7% capacity factor). Its generators came online between 2007 and 2016.
