CALPEAK POWER BORDER PEAKER PLANT, a 52 MW Natural Gas power plant in San Diego County, California. Operated by CALPEAK POWER - BORDER LLC, commissioned 2001.
How CALPEAK POWER BORDER PEAKER PLANT compares
With 52 MW of capacity, CALPEAK POWER BORDER PEAKER PLANT ranks 243rd among the 874 operating power plants Bywatts maps in California and 89th 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 801st-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2001, it is older than 55% of the 859 operating California plants with a recorded commissioning year. It shares San Diego County with 36 other operating plants, including OTAY MESA GENERATING PROJECT and CARLSBAD ENERGY CENTER.
EIA-860 lists 1 generator at the site with 61 MW of nameplate capacity, all natural gas fired combustion turbine technology (this page's HIFLD capacity figure is 52 MW). Net generation was 14.8 GWh in 2024 (a 2.8% capacity factor).
