When the first unit of the facility entered service on December 1, 2010, it was the largest photovoltaic plant in the U.S. at 58 MW.

A 48 MW second phase named Copper Mountain was constructed from January to December 2010 at a cost of about $141 million.

[2] [5] At its construction peak more than 350 workers were installing the 775,000 First Solar panels on the 450-acre (180 ha) site.

Construction on the third, and thus far largest, 250 MW unit began in 2013 and was completed in early 2015, with a formal dedication ceremony on 30 April 2015.

[10] This unit is located about 5 kilometres (3.1 miles) north of the prior grouping, and is capable of generating enough electricity to power about 80,000 homes.
