BESS installations reached a milestone 19 GW last year, up 52% from 2024, including 16 GW of utility-scale storage. This growth spanned 22 states, well beyond the usual California-Texas duopoly
Buzzer beater: In Q4 alone, installations hit 5.8 GW—the highest quarterly total ever documented. Utility-scale drove the bulk at 4.9 GW. Still, residential storage soared 75% YoY to 800+ MW amid expiring tax credits.
Looking ahead: WoodMac expects half a TWh of new storage deployed between 2026-2031—a 250% increase over the prior 5-year stretch.
