U.S. energy storage market sees record growth in Q1 2025
The U.S. utility-scale energy storage market led the way, adding 1.5 GW/4 GWh of capacity in Q1 2025 for a 57% increase over the same period last year. The residential storage
The Wood Mackenzie/American Clean Power U.S. Energy Storage Monitor forecasts 15.2 GW/48.7 GWh of capacity will be added in 2025 across all sectors. The U.S. energy storage market added more than 2 GW, according to the new U.S. Energy Storage Monitor by Wood Mackenzie and the American Clean Power Association (ACP).
Solar accounted for 56% of all new electricity-generating capacity added to the US grid in the first half of 2025, with a total of 18 GW installed. Combined, solar and storage accounted for 82% of new capacity in the first half of the year. The US added 4.3 GW of solar module manufacturing capacity in Q2, bringing the total to 55.4 GW.
In 2025, over 31 GW of new storage capacity is expected to be built. California and Texas are the leaders in battery storage. The California Independent System Operator (CAISO) is set to add about 6 GW of storage next year, while Texas plans to add nearly 12 GW. Storage growth is important because it makes renewable energy more reliable.
The US solar industry installed 7.5 gigawatts direct current (GW dc) of capacity in Q2 2025, a 24% decline from Q2 2024 and a 28% decrease since Q1 2025. Solar accounted for 56% of all new electricity-generating capacity added to the US grid in the first half of 2025, with a total of 18 GW installed.
