On a swing through Nevada, President Obama stopped at the largest operational solar power plant in the U.S.
The mantle of the largest operational U.S. photovoltaic plant belongs to the 55-megawatt (DC) Sempra Copper Mountain solar facility in Boulder City, about 40 miles southeast of Las Vegas.
Construction at the 380-acre desert site began in January 2010 with about 350 construction workers installing almost 775,000 First Solar solar panels. First Solar also served as the engineering, procurement and construction (EPC) contractor.
