The U.S. approved two First Solar Inc. projects with 550 megawatts of capacity that will be built on federal land near the Nevada-California border.
The 300-megawatt Stateline solar farm will be built in San Bernardino County, California, and the 250-megawatt Silver State South project will be constructed near Primm, Nevada, the U.S. Interior Department said today in a statement.
Southern California Edison Co. has agreed to buy power from the two projects, enough for about 170,000 homes, for 20 years, according to the statement.
The U.S. has approved 50 utility-scale wind, solar and geothermal energy projects since 2009, with almost 14 gigawatts of capacity, enough to power 4.8 million homes. Thirteen are in operation.
