The US energy storage market reached a record 18.9 GWh installed capacity in Q2 2026, driven mainly by utility-scale battery storage with increased project duration, despite a slight decline in power capacity installations. The market outlook is strong with expected growth in all segments until 2031, supported by rising electricity demand from data centers and domestic battery manufacturing, although supply chain and trade uncertainties could cause temporary slowdowns.
