U.S. Battery Storage Installations Hit a Record 18.9 GW in 2025, Up 52% From 2024
Independent trade groups, a federal statistical agency, and industry press all confirm the U.S. utility-scale battery storage industry had its biggest year on record in 2025, though the exact gigawatt total varies by roughly 4-5 GW depending on methodology. Wood Mackenzie and the American Clean Power Association's installation-based tally of 18.9 GW (+52% YoY) is the most widely cited figure, while EIA's own reporting lands lower at 13.8-15 GW depending on whether the window is calendar-year or trailing-twelve-month. The disagreement traces to accounting windows, not to any dispute that record growth occurred.

Findings
- Wood Mackenzie and ACP's Q4 2025 U.S. Energy Storage Monitor reported 18.9 GW of utility-scale battery installations for the year, a 52% jump over 2024 and the largest annual total on record.
- SEIA independently corroborated the record, reporting 58 GWh of new battery capacity added in 2025 -- also described as the largest single year of new battery capacity on record.
- EIA's own Today in Energy series cites a lower "record 15 GW added in 2025" on a calendar-year basis, while a separate EIA trailing-12-month snapshot put growth at 13,809 MW (59.4%) -- a reminder that "record year" claims vary by measurement window.
- Despite the 4-5 GW spread in exact totals, every source agrees on direction and magnitude: 2025 outpaced 2024 by roughly 30-60%, driven largely by Texas (ERCOT) buildout and rising data-center electricity demand.
Grid planners, battery OEMs, and clean-energy investors sizing 2026 demand forecasts need to know these figures are not interchangeable; UVRN's delta engine flags exactly where independent trackers diverge so data buyers know which number (installed vs. grid-connected capacity) applies to their use case.
