Grid batteries get record boost from data centers
The U.S. market for grid-scale battery storage recorded its best first quarter ever, driven significantly by the rising power demands of data centers and artificial intelligence. Major tech companies like Google and Meta are investing in advanced battery technologies to ensure facility uptime. The industry faces challenges from federal policy uncertainty, permitting issues, and trade regulations, despite growing demand and domestic manufacturing efforts.
The U.S. market for grid-scale battery storage experienced its strongest first quarter ever, installing 9.7 gigawatt-hours of new capacity, a 32 percent year-over-year increase. This surge is significantly bolstered by the escalating power demands of data centers and artificial intelligence, even amidst federal policy challenges. Shan Tomouk, a lead battery storage analyst at Benchmark Mineral Intelligence, emphasized that energy storage is now crucial energy security infrastructure, not just for backup.
Utility-scale projects currently dominate the storage market, but a report indicates that data centers and other "behind-the-meter" applications are projected to expand their share from 14 to 20 percent by 2030. Large technology firms are actively engaging in this sector; Google announced plans to deploy 30 GWh of long-duration iron-air batteries in Minnesota, while Meta has reserved up to 100 GWh of capacity for a reversible solid oxide fuel cell technology from Noon Energy. These innovative systems aim to provide extended backup for data centers, enabling uptime during multi-day renewable energy lulls. Some operators are also pairing batteries with natural gas, as exemplified by Elon Musk's xAI Colossus facility in Tennessee, which uses Tesla batteries with gas turbines.
Despite the growing demand, the industry confronts several obstacles, including "foreign entities of concern" rules under the Trump administration's "megalaw," which began impacting projects seeking tax credits in January. The Treasury Department has yet to issue full guidance on these rules, creating uncertainty for asset owners tracking Chinese involvement in supply chains. Additionally, the Interior Department's reviews for solar and storage project permitting have left many projects in limbo, though a federal judge recently blocked these reviews, with the Interior Department planning an appeal. Jason Burwen, vice president of policy and strategy at GridStor, highlighted interconnection completion, local permitting, and equipment availability as major deployment challenges, while noting an expected increase in FEOC-compliant battery supply and expanding domestic manufacturing, with companies like Ford, Tesla, and General Motors pivoting to grid battery production.
