The Crescent Dunes Solar Energy Project, is a 110 megawatt (MW) solar thermal power project under construction near Tonopah, about 190 miles (310 km) northwest of Las Vegas. The project is being developed by SolarReserve through its subsidiary, Tonopah Solar Energy. The project is anticipated to cost about $1 billion.
The project includes 17,500 heliostat mirrors that collect and focus the sun's thermal energy to heat molten salt flowing through an approximately 640-foot (200 m) tall solar power tower. The molten salt circulates from the tower to a storage tank, where it is then used to produce steam and generate electricity. Excess thermal energy is stored in the molten salt and can be used to generate power for up to ten hours, including during the evening hours and when direct sunlight is not available.
Under a power purchase agreement (PPA) between SolarReserve and NV Energy, all power generated by the Crescent Dunes project in the next 20 years will be sold to Nevada Power Company for $0.135 per kilowatt-hour. In late September, Tonopah received a $737 million loan guarantee from the U.S. Department of Energy (DOE).
