Report Reveals California Authorities Adjustments Might Endanger Solar Development

| |

According to a new report from the Environment California Research & Policy Center, drastically reducing net metering fees and charging high, all-solar fixed fees could slow the growth of rooftop solar systems – and in extreme cases lead to a collapse in installations. CALPIRG Education Fund and Frontier Group. This report comes as the California Public Utilities Commission (CPUC) is considering changes to the state's net metering program that compensates solar owners for the excess electricity they sell back to the grid.

“California needs continued rooftop solar roof growth to meet our clean energy goals,” said Laura Deehan, state director of Environment California Research & Policy Center. “Our previous leadership in rooftop solar roofs has been intentional, fueled by our commitment to smart policies like net metering. The drastic changes in solar compensation that the CPUC is considering threatens to knock the California rooftop solar management off a cliff. ”

The report Rooftop Solar at Risk: Cuts in net metering could threaten California's cleaner energy advances, highlights several case studies of how solar offsetting affects installation rates. Several studies looked at California's public utilities, which are not required to follow CPUC net metering guidelines, and showed that reduced tariffs had slowed the use of solar power.

In Arizona, the Salt River Project introduced new rooftop solar fees and guidelines that have nearly doubled the payback time of solar projects. The acceptance of solar energy fell between 50 and 95 percent after the changes.

Nevada's net metering pay cut in 2016 was followed by a 47 percent cut in residential solar panels over the next year. Nevada eventually reintroduced net metering.

California's Imperial Irrigation District abandoned net metering in July 2016, which caused residential solar installations to drop 88 percent.

The Turlock Irrigation District in California stopped net metering in early 2015. Within two years, the annual solar installations in private households had decreased by 74 percent.

California law requires the state to achieve 100 percent clean electricity by 2045. To do this, the state estimates that the state will need 39 gigawatts (GW) of customer-side solar power, nearly quadrupling the current distributed solar capacity in California.

“Rooftop solar is cheaper, more efficient, and accessible to more Californians than ever before,” said Jenn Engstrom, state director of the CALPIRG Education Fund. “California has so much to gain from investing in rooftop solar in our homes, schools and businesses, but the utility proposal to offload net metering is effectively pushing rooftop solar off the market.”

Pacific Gas and Electric, Southern California Edison, and San Diego Gas & Electric are proposing to have the nation's highest fixed fees for solar customers while cutting the net census payments solar customers receive.
