The Nellis Solar Power Plant is a 14-megawatt (MW) photovoltaic power station located within Nellis Air Force Base in Clark County, Nevada, northeast of Las Vegas. The power plant was inaugurated in a ceremony on December 17, 2007, with Nevada Governor Jim Gibbons activating its full operation. On average, it has since generated 32 gigawatt-hours of electricity annually and supplied more than 25% of the power used at the base.
