会社のニュース U.S. Energy Storage Installations Surpass 2024 Levels by Q3 2025

United States — December 2025 — According to data from Wood Mackenzie Power & Renewables and the American Clean Power Association, U.S. energy storage installations in 2025 have already exceeded the total capacity deployed in full-year 2024, highlighting rapidly growing momentum in the battery storage sector.

Key Figures

In Q3 2025, the U.S. added more than 5.3 GW of storage, representing over 31 % year-on-year growth. 

At least 12.6 GW of storage capacity has now been deployed through the first three quarters — beating all of 2024’s installations. 

Growth is being driven by utility-scale BESS projects, distributed & residential storage, and continued integration with solar generation.

 Why It Matters

This trend reflects the critical role energy storage now plays in the U.S. electricity mix. As renewables expand, storage is being relied on not just for peak shifting and grid resilience, but also to ensure reliability amid changing energy patterns and demand volatility.

Trends Behind the Headlines

Industry data also show that global storage shipments and deployments are expected to continue strong growth through 2025 and beyond, with stationary energy storage battery shipments predicted to rise sharply this year and next — underscoring the strategic importance of BESS in the global energy transition.
