US Battery Installations Set New Record in Q2 2026

Battery installations in the United States reached a new record in the second quarter of 2026, with 20.2 gigawatt-hours (GWh) of new capacity coming online. This significant increase is sufficient to meet the daily electricity needs of approximately 700,000 homes. The current trajectory suggests that the US will install a total of 71 GWh of batteries in 2026, representing a 20% rise compared to the previous year. This surge in energy storage is attributed to a dual factor: decreasing battery costs and a growing imperative for enhanced energy storage solutions to support the integration of renewable energy sources like solar and onshore wind power into the national grid. Utility-scale battery systems are the primary drivers of this record-breaking quarter. According to a report by Benchmark Mineral Intelligence and the Solar Energy Industries Association, seven new gigascale battery installations, each with a capacity exceeding one GWh, were commissioned during this three-month period. Shan Tomouk, energy storage and energy lead for Benchmark Mineral Intelligence, highlighted that the quarter's success was largely dependent on a "handful of big projects." Alongside these massive utility projects, there was also notable expansion in behind-the-meter battery systems. These systems encompass both residential and industrial battery storage solutions, typically smaller in scale than utility installations and owned by homeowners or businesses rather than energy providers. Within the commercial sector, data centers emerged as significant adopters, accounting for roughly three-quarters of new behind-the-meter batteries. However, the residential battery segment experienced a marked slowdown. These home systems, often used for storing solar power or providing backup during power outages, are projected to see a 16% decrease in installations in 2026 compared to 2025. Tomouk attributes this decline primarily to the expiration of a tax credit that previously subsidized home battery systems at the end of 2025. Despite this temporary setback, Tomouk anticipates a recovery in residential installations by the end of the decade. The growth in utility-scale projects underscores the increasing reliance on grid-level energy storage to manage the intermittency of renewable energy sources and ensure grid stability. The Benchmark Mineral Intelligence and Solar Energy Industries Association report provides critical data on the evolving landscape of energy storage in the US, highlighting the interplay between technological advancements, economic incentives, and grid modernization efforts.
