Grid batteries get record boost from data centers

The U.S. grid-scale battery storage market achieved its strongest first quarter on record, installing 9.7 gigawatt-hours of new capacity for a 32 percent year-over-year increase. This growth is primarily driven by surging electricity demand from data centers and the expansion of artificial intelligence, which are positioning energy storage as critical infrastructure for grid reliability. While utility-scale projects currently dominate the market, the sector is increasingly shifting toward behind-the-meter applications and long-duration technologies to support massive industrial loads.

According to data from the Solar Energy Industries Association and Benchmark Mineral Intelligence, the U.S. energy storage sector added 9.7 GWh in the first quarter of the year despite ongoing permitting and trade uncertainties. While utility-scale projects represent 75 percent of the current market, data centers and behind-the-meter applications are expected to grow from a 14 percent share to 20 percent by 2030. Major tech firms are leading this transition by investing in diverse technologies; Google has announced plans for 30 GWh of iron-air batteries in Minnesota, while Meta has reserved 100 GWh of capacity for Noon Energy’s reversible solid oxide fuel cell technology. These long-duration systems are designed to provide over 100 hours of discharge, ensuring uptime during extended renewable energy lulls.

The surge is concentrated in states with high energy storage targets, led by Texas, Arizona, and California. Beyond traditional renewable pairing, operators are increasingly integrating batteries with natural gas to support AI infrastructure, such as Elon Musk’s xAI Colossus facility in Tennessee, which utilizes Tesla batteries alongside gas turbines. On the supply side, domestic manufacturing is expanding as automakers pivot from electric vehicle components to grid-scale systems. Ford recently joined Tesla and General Motors in announcing plans to produce energy storage systems at a facility in Kentucky, reflecting a broader industry move toward securing domestic supply chains and repurposing existing manufacturing capacity.

The industry faces significant regulatory hurdles, particularly regarding "foreign entities of concern" (FEOC) rules intended to limit Chinese components in the supply chain. Allison Feeney of Wood Mackenzie notes that while many projects began construction early to bypass 2026 deadlines, asset owners must now meticulously track Chinese involvement to qualify for federal tax credits. Additionally, the residential storage segment saw a 28 percent decline in the first quarter following the phase-out of key tax credits. Deployment schedules also remain vulnerable to interconnection delays, local permitting issues, and legal challenges surrounding the Interior Department’s review process for solar and storage projects, which has left numerous developments in limbo.
