VASCO WINDS, a 78 MW Wind power plant in Contra Costa County, California. Operated by VASCO WINDS LLC, commissioned 2011.

How VASCO WINDS compares

With 78 MW of capacity, VASCO WINDS ranks 191st among the 874 operating power plants Bywatts maps in California and 29th of the 89 operating Wind plants in the state. It accounts for about 1.5% of California's operating Wind capacity and 0.1% of all operating capacity in the state. Nationally it is the 319th-largest of the 708 operating Wind plants in the database. Commissioned in 2011, it is newer than 59% of the 859 operating California plants with a recorded commissioning year. It shares Contra Costa County with 18 other operating plants, including DELTA ENERGY CENTER and MARSH LANDING GENERATING STATION.

EIA-860 lists 1 generator at the site with 78 MW of nameplate capacity, all onshore wind turbine technology. Net generation was 223 GWh in 2024 (a 32% capacity factor), about the same as in 2022.
