The Unexpected Clean Energy Winner of 2025: Energy Storage
Energy storage emerged as the unexpected leader in the U.S. clean energy sector in 2025. Despite policy uncertainty and global supply chain challenges, battery storage installations grew rapidly, supported by federal incentives and rising demand from data centers and distributed storage applications. Companies like RackBattery are capitalizing on this growth with reliable, high-performance lithium battery solutions.
How Did U.S. Energy Storage Perform in Early 2025?
At the start of 2025, U.S. energy storage faced uncertainty due to new presidential policies and trade restrictions. Installations had increased by 33% in 2024, reaching 12.3 gigawatts, but proposed tariffs threatened to raise battery system costs by over 35%. Domestic manufacturers struggled to expand, while some greenfield projects were canceled due to high costs and interest rates.
What Role Did Federal Policy Play in Storage Growth?
The passage of the GOP’s “One Big Beautiful Bill” (OBBB) in July preserved key federal incentives for energy storage. Projects continued to qualify for the 48E investment tax credit and the 45Y production tax credit, while the 45X manufacturing credit phased out one year earlier than planned. These incentives provided critical support, allowing storage installations to continue despite a challenging regulatory environment.
Which Markets Are Driving Storage Demand?
Data centers and commercial facilities are major contributors to storage demand. High-performance batteries, including two-hour and long-duration systems, are being deployed for backup and load management. Distributed storage is also gaining traction, with utilities installing batteries at strategic locations to prevent transformer overloads and avoid costly grid upgrades.
Table: Representative Storage Deployment by Sector
| Sector | Project Type | Capacity Example |
|---|---|---|
| Data Centers | Behind-the-meter BESS | 31 MW / 62 MWh |
| Commercial/Industrial | Utility-owned storage | 200 MW |
| Residential | Grid-support batteries | Variable, aggregated use |
How Are Companies Repurposing EV Batteries for Storage?
Automakers and startups are converting EV battery packs for grid storage. GM partnered with Redwood Materials to develop storage systems from new and repurposed EV cells. Ford is shifting Kentucky EV battery production to energy storage, aiming to supply data centers and grid infrastructure. These efforts optimize battery lifecycle and address growing demand in non-transport sectors.
Where Is Distributed Storage Making an Impact?
Distributed energy storage is enhancing grid reliability across the U.S. Utilities like Xcel Energy are procuring batteries from local businesses and commercial sites, strategically placing capacity to avoid transformer overloads and reduce upgrade costs. Residential batteries in Texas, managed by Base Power, simultaneously provide backup power and participate in grid services, demonstrating the commercial potential of distributed storage.
