United States battery installations hit record quarterly high of 20.2 gigawatt-hours
American grid additions reached unprecedented capacity last quarter, according to MIT Technology Review.
The short version
- Grid operators installed a record 20.2 gigawatt-hours of battery capacity in the second quarter of 2026, putting the US on track for a 20% annual increase.[MIT Technology Review]
- Growth was bolstered by seven new gigascale projects, while residential installations are projected to decline 16% this year following the expiration of a federal subsidy.[MIT Technology Review]
- Most current systems depend on Chinese cells, and domestic manufacturing capacity may not meet demand until around 2030.[MIT Technology Review]
Key facts
- US battery installations reached a record 20.2 gigawatt-hours during the second quarter of 2026.[MIT Technology Review]
- The nation is projected to deploy 71 gigawatt-hours of battery capacity across 2026, representing a 20% increase over the previous year.[MIT Technology Review]
- Seven new gigascale battery systems came online during the second quarter.[MIT Technology Review]
- Residential battery installations are forecast to fall 16% in 2026 after a subsidizing tax credit expired in 2025.[MIT Technology Review]
- Nearly all new energy storage installations rely on battery cells manufactured in China.[MIT Technology Review]
What remains uncertain
- US manufacturing capacity may not scale sufficiently to meet domestic battery demand until at least 2030, which could increase prices.[MIT Technology Review]
