US battery storage capacity surged 87.3% year-over-year to reach 23.775 GW by Q2 2024, with 97% of new installations located in ERCOT, WECC, and CAISO. ERCOT and WECC are projected to dominate growth, surpassing 10 GW and 20 GW respectively by 2025. Other regions like ISO New England are catching up, driven by capacity needs and solar/wind limitations.
Lithium prices continue to decline but remain volatile. Q3 is expected to add another 5 GW, with CAISO and ERCOT leading the charge.
