US Battery Storage Capacity Rose 66% in 2024, Adding 10.4 GW in Record Year for Grid-Scale Storage
US utility-scale battery storage expanded by 10.4 GW in 2024, a 66% single-year jump that pushed cumulative installed capacity past 26 GW. EIA data documented batteries as the second-largest category of new generating capacity added in the country, behind only solar. While government data is definitive, the varying depth of independent coverage across trade and environmental media reflects differing editorial judgment on the story's significance. With 19.6 GW planned for 2025, grid-scale storage has become central to US electricity reliability strategy.
claim: US utility-scale battery storage capacity increased 66% in 2024, with generators adding 10.4 GW of new capacity — the second-largest source of new generating capacity in the country after solar.

Findings
- EIA documented 10.4 GW of new utility-scale battery storage added in the US in 2024 — the second-largest source of new generating capacity after solar.
- Cumulative US utility-scale battery capacity exceeded 26 GW by end-2024, a 66% year-over-year increase from approximately 15.7 GW at end-2023.
- California led state deployments with 7.3 GW of installed capacity; Texas followed at 3.2 GW, with the two states representing roughly 40% of the national total.
- Operators filed plans to add 19.6 GW of additional utility-scale battery storage in 2025, which EIA projects could set another single-year record.
Grid operators, utilities, and clean energy investors need to know whether record deployment claims hold up across multiple independent trackers. UVRN verifies whether government data, market intelligence, and trade reporting converge on the same finding — or diverge on scale.
