Crescent Dunes Solar Energy, a 110 megawatt (MW) concentrating solar power (CSP) electricity plant, began full operation in February, according to its press release . Crescent Dunes uses an energy storage system that developers expect will be able to store enough thermal energy to generate electricity for up to 10 hours after sunset or on cloudy days when direct sunlight is unavailable. Through December 2015, CSP made up 8% of total U.S. solar electric generating capacity, while utility-scale solar photovoltaic (PV) made up 53%, and distributed solar PV made up 38%. Solar thermal electricity power plants differ from PV technology , which uses solar cells to convert direct and diffuse sunlight directly into electricity. Solar thermal plants rely on direct sunlight to focus the sun’s heat energy onto collectors. Most of the earlier utility-scale CSP projects […]
