The solar facility, which had become operational earlier this year, is expected to generate electricity enough to power around 53,000 homes annually, by reducing 36,000 tons of carbon emissions.
PG&E is purchasing the clean energy generated by the solar plant, under a 20-year power purchase agreement.
Commenting on the solar power facility, NRG Solar senior vice president Randy Hickok said that the Alpine solar photovoltaic facility marks a dramatic shift in the way energy is generated in California.
"As the largest operating photovoltaic facility in the state, Alpine is not only providing PG&E with a renewable source of energy, but contributing to cleaner air and a smaller carbon footprint for the state, ultimately helping meet California’s renewable portfolio standards," added Hickok.
Apart from Alpine, NRG currently owns seven large-scale photovoltaic solar facilities, including Agua Caliente and Avra Valley in Arizona; Roadrunner in New Mexico; and Avenal, Blythe, Borrego and California Valley.
NRG Solar, a subsidiary of NRG, has more than 2,000MW of photovoltaic and solar thermal projects in operation, under construction or in development across the southwestern United States.
