A BETTER DEAL FOR CALIFORNIANS: The Rise of Battery Storage Over Gas Generation
REGENERATE CALIFORNIA & CEERT
June 2025

2024 marked the year of batteries, as they proved essential to grid reliability and significantly improved the efficiency of California’s electricity system. Batteries have enabled the grid to operate with dramatic decreases in fossil fuel use, proving that battery storage technology can reduce the state’s reliance on fossil gas plants. In 2023 and 2024, the California Independent System Operator (CAISO) reported improved system reliability with zero flex alerts—requests sent to residents asking them to voluntarily curb energy use in times of peak demand. Increased battery system availability has avoided the return of rolling blackouts that occurred in August 2020.

In addition to being a more reliable energy technology than gas plants, batteries are also significantly more cost-effective and offer great potential to improve energy affordability for ratepayers through a transition to zero-carbon energy.
