Battery Storage in the United States
Grid batteries are the fastest-growing resource on the US power system. This page tracks the numbers that matter — installed capacity, where it's being built, and where counties are pushing back — with live headlines from our monitoring pipeline.
How much battery storage does the US have in 2026?
The United States has more than 40 GW of utility-scale battery storage on the grid as of early 2026, per the EIA's Electric Power Monthly. Operators added a record 15 GW in 2025 and plan another 24.3 GW in 2026. In energy terms, the US fleet reached 137 GWh of utility-scale storage in 2025 (SEIA/Benchmark Mineral Intelligence).

Which states are adding the most battery storage?
Three states account for about 80% of battery storage planned for 2026: Texas (12.9 GW, 53% of the national total), California (3.4 GW), and Arizona (3.2 GW), per EIA data. California leads today's installed fleet, but Texas is projected to overtake it as the largest battery storage market during 2026.
| State | Planned 2026 additions | Share of US total |
|---|---|---|
| Texas | 12.9 GW | 53% |
| California | 3.4 GW | 14% |
| Arizona | 3.2 GW | 13% |
| All other states | ~4.8 GW | ~20% |
Planned utility-scale additions for 2026, per EIA. About half of US storage is co-located with solar. See the Texas, California, and Arizona guides for market context.
