California proposes big changes to rooftop solar incentives

Sammy Roth, THE LOS ANGELES TIMES

Walker Wright, vice president of public policy at San Francisco-based Sunrun, the nation’s largest rooftop solar installer, said in a written statement that Guzman Aceves’ decision would “impose the highest discriminatory charges on solar and energy storage customers in the U.S., putting rooftop solar and batteries out of reach for countless families in California just as more households are demanding that the state do more to combat climate change and provide them with reliable, sustainable energy.”

California officials want to slash payments for rooftop solar power while adding incentives for homes and businesses to install batteries, saying the changes will help the state achieve 100% clean energy in a way that keeps the lights on, prevents electricity rates from spiraling out of control and also encourages people to drive electric cars.

The proposal from Martha Guzman Aceves, one of five members of the California Public Utilities Commission, would revamp an incentive program called net energy metering that has helped the state become a national solar power leader, with more than 1.3 million rooftop and other small-scale systems installed. The solar industry and climate change advocacy groups have lobbied Gov. Gavin Newsom and his appointees on the utilities commission to keep the program’s basic tenets unchanged.

But in an interview, Guzman Aceves said net metering needs to evolve to reflect California’s changing energy needs. The Golden State’s power grid is increasingly flooded by solar energy during the afternoon but strained on hot summer evenings, when millions of people throttle up their air conditioners to cope with high temperatures made worse by the climate crisis.
