The U.S. energy storage market hit a record in 2025, with 18.9 gigawatts of battery energy storage system installations—a 52 percent increase over 2024, according to a new report from the American Clean Power Association (ACP) and Wood Mackenzie.

The U.S. Energy Storage Monitor report also found that residential market reached a record high of 2.7 GW installed, a 92% jump from 2024. Looking ahead, the report projects the U.S. will install half a terawatt-hour of storage between 2026-2031, a 250% increase over the previous five-year period. 

“The record-breaking energy storage growth seen in 2025 highlights how technology innovation is transforming America’s grid,” said John Hensley, senior vice president of markets and policy analysis at ACP. “This momentum, driven by supportive policy and expanding market opportunities, demonstrates that large-scale storage is now a cornerstone of delivering affordable, reliable, and American-made energy in communities nationwide. Continued collaboration across industry and government will be essential to building on this progress and meeting soaring energy demand.”
