California scores more clean energy records: 9 in 10 days this year partially powered by 100% clean energy
What you need to know: New data shows California’s power grid has run on 100% clean energy for some part of the day nearly every day this year – thanks to the state’s commitment to investing in new resources.
SACRAMENTO – More than 9 out of 10 days so far this year have been powered by 100% clean energy for at least some part of the day in California. In 2025, California’s grid has run on 100% clean electricity for an average of 7 hours a day.
Data compiled by the California Energy Commission shows clean energy has powered the equivalent of 51.9 days in the state – nearly 30% of the year to date running on 100% clean electricity. That already surpasses the amount of “clean energy days” last year – and represents a 750% increase in clean energy days 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.”
Governor Gavin Newsom
California has installed a record amount of clean energy – faster
The addition of new clean energy resources – including battery storage – to the state’s grid has helped make clean energy days a reality in California.
Earlier this year, Governor Newsom announced more than 25,000 megawatts (MW) of new resources have been added to the state’s electric grid over the past five years — an amount equivalent to roughly half of the state’s record peak demand in 2022 and in addition to existing capacity.
In 2024 alone, California added approximately 7,000 megawatts (MW) of new clean energy nameplate capacity —representing the largest single-year increase in clean energy capacity added to the grid in state history. This new figure broke the previous records set in both 2022 and 2023, marking a third consecutive year of unprecedented clean energy growth.
Since the beginning of the Newsom Administration, battery storage is up to over 15,000 megawatts – a 1,944% increase.
