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 794th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1986, it is older than 72% of the 859 operating California plants with a recorded commissioning year. Its operator, NORTHERN CALIFORNIA POWER AGNY, runs 7 operating plants in California totaling 605 MW. It shares Alameda County with 9 other operating plants, including RUSSELL CITY ENERGY CENTER and DYNEGY OAKLAND POWER PLANT.

EIA-860 lists 2 generators at the site with 55 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 3.1 GWh in 2024 (a 0.7% capacity factor).
