U.S. top 11 states by non-pumped energy-storage net capacity gain; MW, 2023–2024.
This comparison ranks states in the United States by the increase in utility-scale non-pumped energy-storage net summer capacity from 2023 to 2024. Values are measured in megawatts using annual EIA observations. Texas records the largest increase at 4,111.4 MW, rising from 3,798.6 MW to 7,910.0 MW. California is second at 3,732.7 MW, followed by Arizona at 1,190 MW.

Evidence: Supports the 2023 and 2024 state values used to calculate the complete 24-state ranking.
The ranking uses EIA's Other Energy Storage measure and excludes hydroelectric pumped storage, which is reported separately.
State values come from the U.S. Energy Information Administration's Electric Power Annual 2024. Each gain equals the final 2024 value minus the 2023 value, and only states with a positive change are ranked. Census divisions, the U.S. total and the District of Columbia are excluded. The graphic highlights the top 11 states, while the page data retains all 24 eligible states.
Every state uses the same U.S. EIA annual release, the same 2023 and 2024 endpoints and one common measurement basis, supporting a like-for-like comparison.
