US battery storage installations reached a record 3.3 GW in Q1 2026, up 54% year-over-year, with utility-scale, commercial, and residential segments all hitting new highs. The sector is projected to reach 200 GW cumulative capacity by 2031, though supply chain constraints from foreign entity rules could create bottlenecks.

If you make battery components, casings, thermal systems or monitoring gear, developers are now locking in multi-year domestic supply contracts to dodge foreign entity rules—call your largest pipeline customers this week before they sign elsewhere. The tax credit window that drove this spike is closing; whoever secures supply agreements in the next six months owns the next five years.
