Industry forecasts predict a substantial increase in US battery energy storage systems in 2026, with deployments projected to reach 70 GWh, driven by utility-scale projects and expanding behind-the-meter systems, mainly in California, Texas, and Arizona.
The United States is set for another substantial year of battery deployment as industry forecasters point to continued maturation of grid and behind‑the‑meter storage markets. According to the report by the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence, US battery energy storage system (BESS) deployments are expected to reach about 70 GWh in 2026, roughly 21% higher than 2025, supported by both utility‑scale projects and growing behind‑the‑meter activity.
SEIA and Benchmark estimate the 2026 pipeline will comprise some 20.2 GW/62.4 GWh of utility‑scale capacity and 14.8 GW/7.3 GWh of behind‑the‑meter systems, implying roughly US$25.2 billion of capital investment. The outlook also sketches a longer‑term expansion: annual installations surpassing 47 GW/110 GWh by 2030 and total installed utility‑scale BESS approaching 500 GWh by that year, according to the same assessment.
The industry’s recent trajectory is already notable. SEIA and partner analysis record a near‑record year in 2025, with about 57–57.6 GWh of new storage added, a jump of nearly 30% on the prior year, industry reporting shows. That surge has been driven principally by large-scale deployments; utility‑scale capacity dominated 2025 installations while behind‑the‑meter systems retained a steady share of the market, accounting for about 13% of 2024 capacity, equivalent to roughly 12 GW/8 GWh, with residential uptake accelerating after the expiry of the 25D tax credit.
Geography remains concentrated. SEIA data show California, Texas and Arizona together account for roughly three‑quarters of installed capacity, with California leading followed by Texas and Arizona; Nevada is the next largest state but lags the top three by a wide margin. Across asset types, about 48% of storage capacity is deployed paired with solar, 51% is standalone BESS and around 1% is paired with wind generation, the report states.
Several market forces are underpinning the growth. Analysts cited by industry outlets point to improving merchant revenue stacks, utilities’ appetite for rapid‑response capacity and lower combined levelised costs for renewables plus storage, which make more projects bankable without sole reliance on direct subsidies. The retention of battery tax credits in recent federal policy moves has also been singled out as helping to sustain investment momentum even amid uneven policy signals at the national level.
Broader power sector planning aligns with the storage uptick. Trade reporting indicates developers plan to add a record volume of new generating capacity in 2026, with solar and battery storage making up the lion’s share; one sector analysis projects roughly 24 GW of new utility‑scale battery capacity planned for 2026, concentrated primarily in Texas, California and Arizona.
The international context is mixed. Global grid‑scale deployment data for early 2026 show lower month‑on‑month additions and continued dominance by China, while January 2026 global starts were below the same month a year earlier, according to market trackers referenced in industry briefings. North America’s January commissioning activity was modest in that snapshot.
For industrial decarbonisation professionals, the near‑term implications are clear. Continued utility procurement and merchant opportunities are expanding the addressable market for system integrators, EPCs, battery manufacturers and ancillary‑service providers. The concentration of projects in a handful of states underscores the continued importance of regional market design, transmission planning and interconnection processes in determining where capacity can be realised at scale. Meanwhile, the growing share of solar‑paired and standalone batteries highlights diverse commercial models: co‑located solar plus storage for seasonality and capacity value, and standalone BESS deployed to provide grid services and fast capacity response.
As the sector scales, attention will shift to project bankability, supply‑chain bottlenecks, and policy stability that can convert the pipeline into sustained, geographically broader deployments. The SEIA and Benchmark outlook provides a bullish baseline for 2026 and beyond, but the pace and shape of roll‑out will continue to reflect utility procurement cycles, merchant revenue dynamics and the resolution of local permitting and interconnection constraints.

This represents a 30% increase over the previous record set in 2024 and is nearly four times the capacity added just three years ago, highlighting the rapid growth of the sector despite regulatory and policy challenges at the federal level. According to the U.S. Energy Storage Market Outlook Q1 2026 (ESMO), released by the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence, utility-scale storage accounted for 137 GWh of the total installed capacity in the United States as of 2025.
- https://www.wired.com/story/the-us-had-a-big-battery-boom-last-year/ – In 2025, according to the SEIA report, the US installed 57 gigawatt hours of new energy storage to the grid, with new installations growing almost 30 percent over the year before. That’s enough storage, the SEIA report claims, to power more than 5 million homes each year. The report predicts that the market could jump another 21 percent by the end of this year, increasing by an additional 70 gigawatt hours in 2026 alone. These are monster numbers compared to less than a decade ago, when there was about half a gigawatt of storage on the grid in total. Batteries have proven remarkably politically resilient. Tax credits for wind and solar were cut as part of the One Big Beautiful Bill last summer amid a large-scale attack on renewables from the administration, despite opposition from Republican lawmakers with clean-energy projects in their states. But battery tax credits were largely spared. And despite Washington’s hostility toward renewable energy, batteries—along with solar—saw significant growth in some deep red states last year.
