Crescent Dunes Solar Plant is a 110-megawatt solar facility north of Tonopah, Nevada, due to go online in 2014. Like the Ivanpah Plant that recently went online south of Las Vegas, this is a central collecting thermal type. It has a 550-foot tall tower, surrounded by 17,500 heliostats that reflect sunlight onto it, heating a molten salt, which then makes steam and electricity. The heated salt is stored in a tank on-site, and retains its heat long enough to generate steam after the sun has set. This is enables the plant to produce electricity day and night, not just during the sunny parts of the day, like most other solar power plants.
