Project Summary

This competitively bid, public works project for the Chabot-Las Positas Community College District involved a 1.5 Megawatt (MW) solar photovoltaic ground-mount system. Cupertino Electric's renewable team engineered and constructed the solar system over a few months on the district’s six acres of land in Livermore, California to help reduce the district’s operational costs. The power generated by the photovoltaic system during the life of the system is anticipated to be 34,229,925 kilowatt-hours (kWh), which is roughly the equivalent of reducing annual greenhouse gas emissions from 4,628 passenger vehicles.

In addition to the solar system, Cupertino Electric conducted an energy audit and retrofitted traditional lights with LED lights at the district to realize a nearly 50 percent (50%) energy savings using new fixtures. New mechanical equipment with Variable Frequency Drives (VFDs) replaced older equipment to increase energy savings.
