Homes Powered: About 41,000 (CA)
Completed: Year-end 2016
Customer: Southern California Edison

Copper Mountain Solar 4 is the fourth phase of the landmark Copper Mountain Solar complex in Boulder City, Nevada, one of the largest photovoltaic (PV) solar facilities in the country.

Construction activities on the 94-megawatt (MW) expansion project began in 2015. The project created about 350 construction jobs at peak, and was completed by year-end 2016. It produces enough electricity to power approximately 41,000 California homes.

Starting in 2020, renewable electricity generated from the facility will be sold to Southern California Edison under a 20-year power purchase agreement. In the interim, from project completion in 2016 until the contract starts in 2020, output will be sold to off takers within the California Independent System Operator (CAISO) market.
