US Energy Storage Monitor

U.S. Energy Storage Market Q1 2026 Sets Records Across Sectors

Delivered quarterly, the US Energy Storage Monitor from the American Clean Power Association (ACP) and Wood Mackenzie Power & Renewables provides the clean power industry with exclusive insights through comprehensive research on energy storage markets, deployments, policies, regulations and financing in the United States.

The U.S. energy storage market installed a record 3.3 gigawatts (GW)/8.4 gigawatt-hours (GWh) of battery energy storage systems in Q1 2026, surpassing the previous Q1 record by 54% with utility, commercial, and residential installations all hitting new highs, according to the latest U.S. Energy Storage Monitor report.

Utility-scale activity dominated, with more than 2.3 GW/6.8 GWh installed in Q1 2026. Q1 growth was largely driven by 2025 project delays as developers focused on meeting tax incentive eligibility deadlines for pipeline projects in the second half of 2025. Texas, California and Arizona continued to top the charts, but new markets with vertically integrated utilities also gained traction, particularly in Michigan and Georgia.

Battery energy storage system installations are projected to reach 200 GW/655 GWh of cumulative installed energy storage capacity by 2031, driven mainly by the utility sector, which will make up 85% of installations between 2026 and 2031.

Report Highlights:

• The U.S. installed 3.3 GW/8.4 GWh of battery energy storage systems across all sectors in Q1 2026, surpassing the previous Q1 record by 54%
• 2.3 GW/6.8 GWh of utility-scale capacity was installed in Q1
• Residential segment installed a record 1.3 GWh in Q1 2026
• The U.S. energy storage market is poised to grow by 275% in cumulative installed capacity over the next six years

The report also includes key quarterly trends and analysis on impactful market regulation, policy, system prices, and supply chain across all segments. The report provides industry professionals with actionable and intelligent insights to better inform business decisions.
