SolarReserve’s Sandstone project would include up to 10 concentrated solar arrays, each equipped with a molten salt system capable of storing the sun’s energy to generate power after dark, CEO Kevin Smith said.
The company already has built one such array, the 110-megawatt Crescent Dunes Solar Energy Plant, on 1,600 acres of federal land outside of Tonopah, 225 miles northwest of Las Vegas. The $1 billion array began delivering power to NV Energy late last year.
Smith said project Sandstone would generate between 1,500 and 2,000 megawatts, enough to supply about a million homes. That’s on par with a nuclear power plant or the Hoover Dam and far bigger than any of the world’s existing solar facilities.
