SunPower, PG&E sign contract for 100 MW Henrietta Solar Project

San Jose, Calif., September 7, 2012 — SunPower Corp. signed a power purchase agreement with Pacific Gas and Electric (PG&E) for delivery of the 100-MW (AC) Henrietta Solar Project in Kings County, Calif.

The project is expected to create about 200 jobs during construction and inject $72.7 million into the local economy.

PG&E estimates that the 100-MW project will provide the equivalent power required for about 36,000 average California homes.

At the site, SunPower will deploy the SunPower Oasis power plant, the energy industry’s first modular solar power block that provides a cost-effective way to rapidly deploy utility-scale solar.

Engineered to optimize use of available land, each SunPower Oasis power block uses high-efficiency, 435-watt SunPower solar panels with the SunPower T0 Tracker, which positions the panels to track the sun during the day, resulting in up to 25 percent more energy capture over fixed-tilt solar power systems.

Additional SunPower Oasis features include pre-manufactured cabling to minimize on-site wiring, the Oasis smart inverter control system to enhance grid interoperability, and SunPower’s Tracker Monitoring and Control System for wireless control of the power plant.

This contract is contingent on approval by the California Public Utilities Commission and SunPower’s ability to complete all applicable permits. It is expected that construction will begin in 2015, with the plant beginning commercial operation by late 2016.
