NRG Energy and its affiliate NRG Yield have announced the completion of the 250MW California Valley Solar Ranch project, built by PV manufacturer SunPower.
Power from the plant, in San Luis Obispo County, California, will be sold to Pacific Gas & Electric under a power purchase agreement, providing power to an estimated 100,000 homes.
SunPower designed and provided engineering, procurement and construction services for the project, which began in September 2011.
CVSR uses SunPower’s Oasis Power Plant design, a modular system for utility-scale plants that installs modules in 1.5MW blocks that speed up construction and make better use of available land, SunPower said.
NRG and SunPower will jointly operate and maintain CVSR for two years, after which NRG will assume sole responsibility for operating the site.
“CVSR is now delivering 250MW of cost-competitive solar power in San Luis Obispo County, thanks to the combined efforts of NRG Solar and SunPower, PG&E, San Luis Obispo County officials and community members, our subcontractors and vendors, and the hard-working women and men who engineered and constructed this remarkable project,” said Howard Wenger, SunPower president, regions. “SunPower is very proud to have developed and built this project, which combines our world-leading solar technology with eco-design principals to responsibly maximise energy delivery over the life of the system.”
The plant is jointly owned by NRG and NRG yield.
