Highlights
- In 2024, California added 3,774 MW of net operable energy storage capacity, a growth of 27.9% compared to 2023, while the rest of the U.S. added 7,355 MW, an increase of 88.4%.102 Nationwide, energy storage capacity almost doubled from 2023 to 2024, but most of that occurred outside of California. Most of the energy storage systems that came online in 2024 are composed of lithium-ion (Li-ion) batteries.
- Looking ahead, the energy storage pipeline is robust for the near future. As of the end of 2024, California has 8,551 MW of proposed energy storage capacity in the pipeline for 2025 to 2027 while the rest of the U.S. has 45,773 MW of proposed energy storage capacity in the pipeline. California has more energy storage capacity in the pipeline for 2025 to 2027 than the cumulative capacity added from 2013 to 2023 (7,913 MW currently online plus 19 MW retired).
102 This excludes retired units. Additionally, these include only utility-scale energy storage systems. Whereas, the California Energy Commission’s California Energy Storage System Survey have capacities reported as low as five kilowatts (kW). This means the EIA’s data on Form 860 is not directly comparable with the CEC’s survey data.
