NRG Energy, through its NRG Solar unit, started commercial operations for the Avra Valley Solar Generating Station, a 25 MW photovoltaic facility near Tucson, Ariz. The station's electricity will be sold to Tucson Electric Power under a 20-year power purchase agreement.
The Avra Valley array will generate enough energy to meet the annual needs of approximately 5,000 homes, and up to 20,000 homes at peak capacity. Using clean solar power also avoids the annual emission of about 51,500 metric tons of carbon dioxide into the atmosphere, the equivalent of taking more than 10,700 cars off the road.
Avra Valley is the sixth large-scale solar facility in NRG's operational fleet, producing clean solar power for thousands of homes and businesses in three states. The other five are Agua Caliente in Yuma County, Ariz. (to be completed in 2014); Roadrunner in Doña Ana County in New Mexico; and Avenal, Blythe and California Valley Solar Ranch (to be completed in 2013) in California.
