Castaic Power Plant, the largest pumped-storage power station in California. Pumped-storage hydroelectricity is important means of large-scale grid energy storage that helps improve the daily capacity factor of California's electricity generation system. This is a list of all operational pumped-storage power stations in California.
Scattergood has an 830 MW [1] capacity spread across three steam turbine units. [2] [1] Owned and operated by the Los Angeles Department of Water and Power (LADWP), the station is a coastal landmark of the Santa Monica Bay in southern California. Plans are in place to convert the station to hydrogen power.
The Valley Steam Plant was constructed in 1953 by the Los Angeles Department of Water and Power (LADWP) to provide electricity for Greater Los Angeles.Built on 150 acres (61 ha) in Sun Valley at cost of $80,000,000, it was powered by dual fuel (gas or oil) boilers and had four steam turbines generating a total of 512 MW.
Fields of heliostat mirrors focus sunlight on receivers located on centralized solar power towers. The receivers generate steam to drive specially adapted steam turbines. For the first plant, the largest-ever fully solar-powered steam turbine generator set was ordered, with a 123 MW Siemens SST-900 single-casing reheat turbine. [19]
Heat recovery, performed by two Vogt-NEM three-pressure reheat HRSGs, uses waste heat from the combustion turbines to generate steam to power an additional turbine. [8] [18] [19] This steam turbine, also made by General Electric, is a model D11 tandem compound reheat double-flow steam turbine generator.
The Geysers is the world's largest geothermal field, containing a complex of 18 geothermal power plants, drawing steam from more than 350 wells, located in the Mayacamas Mountains approximately 72 miles (116 km) north of San Francisco, California.
Mohave Generating Station, a 1,580 MW steam–electric power plant near Laughlin, Nevada fuelled by coal. A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator.
The Geysers in Sonoma and Lake counties, California was developed into what is now the largest geothermal steam electrical plant in the world, at 1,517 megawatts. Other geothermal steam fields are known in the western United States and Alaska. Geothermally generated electric power can be dispatchable to follow the demands of changing loads.
