The energy landscape shifted permanently in 2025. According to the new U.S. Energy Storage Market Outlook from SEIA and Benchmark Mineral Intelligence, the U.S. storage industry didn’t just grow, it exploded, installing 57.6 GWh of new capacity.
At Wattmore, we’ve been watching the "Storage Century" unfold, but these findings highlight a market moving faster than almost anyone predicted. Here is our breakdown of the report and what it means for the industry.
1. A New Manufacturing Powerhouse
For years, the narrative was that battery manufacturing belonged overseas. The 2025 data flips that script. The U.S. is now the second-largest battery manufacturer on the planet. With 69.4 GWh of domestic manufacturing capacity, the "Made in the USA" label is becoming the standard for battery energy storage systems (BESS).
2. The Texas Takeover and the "Red State Boom”
One of the most surprising takeaways? Energy storage is a bipartisan winner. Two-thirds of all utility-scale storage installed in 2025 was built in states won by President Trump. While California has long been the leader, the report predicts Texas will overtake California in 2026 as the nation’s largest energy storage market. This shift proves that storage isn't a political preference, it’s an economic necessity for grid-heavy states facing high demand.
3. The Rise of the Virtual Power Plants
Residential storage grew by a staggering 51% year-over-year. Why? Because homeowners aren’t just buying batteries for backup; they are participating in the grid. The expansion of Virtual Power Plant (VPP) programs in Massachusetts, Texas, Arizona, and Illinois is turning individual homes into collective assets that manage peak demand and lower costs for everyone.
4. Looking Ahead: The $25 Billion Opportunity
The report forecasts that 2026 will see $25.2 billion in capital investment in the storage sector. By 2030, we expect to see over 600 GWh of cumulative storage installed.
The Wattmore Perspective The "One Big Beautiful Bill Act" (OBBBA) and state-level commitments have created a tailwind that is hard to ignore. However, as SEIA leadership noted, the industry requires consistent federal policy to avoid price spikes and system fragility.
For developers, project asset owners, investors, and utilities, the message is clear: The transition to a resilient, storage-backed grid is happening now. The question is no longer if you should integrate storage, but how fast you can scale. At WATTMORE, we are ready to help you capture this market opportunity with our patented Energy Management System (EMS) Intellect Operate, and our battery sizing and advice engine Intellect Plan.
