Butte College, located 75 miles from Sacramento, said it will see significant benefits from its solar arrays, estimating savings between $50 million and $75 million over 15 years.
The savings will come from eliminating it electricity bill, getting paid for excess electricity production delivered back to the grid, and avoiding future electricity rate increases, a college release said Wednesday.
"Butte College has had a longstanding commitment to sustainability," Diana Van Der Ploeg, Butte College's president, said.
"Achieving grid-positive status marks the culmination of years of effort to build Butte College's supply of solar power and to improve energy efficiency on campus."
The school now has a total of 25,000 solar panels generating more than 6.5 million kilowatt hours of electricity per year, enough to power nearly 1,000 average-sized homes.
"Future generations are counting on us to address the profound challenge of global warming, and we know that our future prosperity will hinge on America's ability to be a leader in the clean energy economy," House Democratic leader Nancy Pelosi, D-Calif., said. "Butte College's accomplishments in renewable energy and sustainability help show the way toward building a stronger economy while preserving the planet."
