The El Dorado Solar Power Plant is a 10 megawatt (MWAC) photovoltaic power plant located near Boulder City, Nevada and completed in December 2008. It was built by First Solar as a demonstration plant for Sempra Generation, and is now part of Sempra's multi-unit Copper Mountain Solar Facility. The power from the original 10 MW plant is being sold to Pacific Gas & Electric under a separate 20-year power purchase agreement.
