Environmental and consumer advocacy groups are seeking to reverse a 2022 decision by state regulators to slash by around 75% the rates paid to compensate customers with solar installations for the excess energy they generate. The move, intended to shield non-solar customers from unfair cost burdens, sent solar hookups plummeting.

Three environmental groups bringing the case — the Center for Biological Diversity, The Protect our Communities Foundation, and the Environmental Working Group — argue that the California Public Utilities Commission didn’t properly consider benefits to customers and disadvantaged communities when it changed the program. The commission argued the policy strikes a balance between affordability for all customers and encouraging renewable energy choices.

The California Public Utilities Commission’s (CPUC) Public Advocates Office (PAO) issued in August 2024 an analysis that purported to show current rooftop solar customers are causing a “cost shift” onto non-solar customers amounting to $8.5 billion in 2024. Unfortunately, this rather simplistic analysis started from an incorrect base and left out significant contributions, many of which are unique to rooftop solar, made to the utilities’ systems and benefitting all ratepayers. After incorporating this more accurate accounting of benefits, the data (presented in the chart above) shows that rooftop solar customers will in fact save other ratepayers approximately $2.3 billion in 2024.
