The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix, completed in 2013. When commissioned it was the largest parabolic trough plant in the world and the first U.S. solar plant with molten salt thermal energy storage. Built by the Spanish company Abengoa Solar,[3] it has a total capacity of 280 megawatts (MW),[3] which is enough to power 70,000 homes while avoiding around 475,000 tons of carbon dioxide.[3] Its name is the Spanish term for "sunny spot".[4]
