More than 90% of days this year in California have seen the state’s power grid run on 100% clean energy for at least part of the day. On average, California’s grid has operated on entirely clean electricity for seven hours daily in 2025.
Data from the California Energy Commission indicates that clean energy has powered the equivalent of 51.9 days in the state, accounting for nearly 30% of the year to date. This surpasses last year’s “clean energy days” and represents a significant increase since 2022.
“The fourth largest economy in the world is running on more clean energy than ever before. Clean energy met our grid’s total demand for some part of the day almost every day this year – the equivalent of 51 full days powered by 100% clean electricity. Trump and Republicans can try all they want to take us back to the days of dirty coal but the future is cheap, abundant clean energy,” said Governor Gavin Newsom.
The installation of new clean energy resources, including battery storage, has contributed to these achievements. Governor Newsom announced earlier this year that over 25,000 megawatts (MW) of new resources have been added to California’s electric grid over five years—equivalent to roughly half of the state’s record peak demand in 2022.
In 2024 alone, approximately 7,000 MW of new clean energy capacity was added, marking a record-breaking single-year increase in state history. Since Governor Newsom took office, battery storage capacity has increased by over 15,000 MW—a growth rate exceeding 1,944%.
