Project Summary: 

This substation project for utility Sempra U.S. Gas & Power in Boulder City, Nevada services an addition to one of the largest thin-film photovoltaic (PV) solar energy plants in the U.S. In addition to the substation scope of work at the Copper Mountain Solar 2 site, Cupertino Electric installed a 230kV transmission line spanning one-and-a-half miles to connect the solar farm’s substation with an existing Phase 1 solar substation.

Connecting the solar farm to the grid, Cupertino Electric built the substation facilitates to deliver power from the solar modules to customers of utility PG&E, who is purchasing the power generated by the Copper Mountain Solar 2 site. Construction of the substation began in late 2011 was completed in the summer of 2012.

When the second phase of construction is complete in 2015, the project’s entire operating capacity will be 150 MW and is expected to generate enough energy to power 45,000 homes.
