The US energy storage industry achieved its most successful first quarter of 2026 to date, driven by surging AI computing demands and growing concerns over fossil fuel reliability. According to the US Energy Storage Market Outlook (ESMO) second quarter 2026 report published by the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence, developers deployed 9.7 gigawatt-hours (GWh) of new storage capacity in the first quarter of 2026. This represents a 32% increase year-over-year, reflecting the sector’s resilience within the domestic clean energy supply chain despite a strained political environment.
