15.2 Gigawatts Deployed. Battery Manufacturing Investment Down 38%.

The United States installed 15.2 gigawatts of battery storage in 2025, a 35% increase over 2024 and the largest annual addition in the technology’s history. In the same year, clean energy manufacturing cancellations reached approximately $23 billion, representing three-quarters of all projects canceled since tracking began in 2018, and new factory announcements fell to their lowest level since the pandemic.

That divergence played out during a year of record deployment, falling cell costs, and bipartisan consensus that the grid needs more storage. The deployment market and the manufacturing market told opposite stories for twelve straight months.

The record. BloombergNEF’s 2026 Sustainable Energy in America Factbook confirms 15.2 GW of battery storage added in 2025, up 35% year-over-year, making storage a central component of new U.S. generation capacity. Canary Media separately confirmed more than 13 GW of grid-scale battery installations, supplementing the broader BNEF figure that includes all storage types. Battery storage is no longer a supplemental grid resource; it is core infrastructure.

The collapse. Battery manufacturing investment fell 38% year-over-year in Q4 2025, according to the Rhodium Group and MIT Clean Investment Monitor, despite batteries accounting for 85% of all clean energy manufacturing investment. Across all clean energy manufacturing, Q4 recorded $8 billion in project cancellations, the worst single quarter in the monitor’s seven-year history. The full-year total reached approximately $23 billion, representing three-quarters of all cancellations since tracking began in 2018.

New manufacturing announcements fell to $3 billion in Q4, down 48% from both the prior quarter and the year-ago period. That is the lowest level since Q4 2020, when the pandemic had frozen capital allocation across the economy. The EV supply chain (critical minerals, batteries, vehicle assembly, and charging) declined for a fourth consecutive quarter.

The pipeline. Storage interconnection applications across the seven major ISOs declined 20% year-over-year, per BNEF. The queue still holds 377 GW of proposed storage projects, but the rate of new entries is falling. Permitting delays, grid operator study pauses, and Foreign Entity of Concern compliance uncertainty are thinning the forward pipeline.

The lag. The 15.2 GW installed in 2025 was largely planned and permitted between 2022 and 2024, during the investment surge that followed the Inflation Reduction Act. Interconnection applications filed in 2024 and 2025 determine what gets built in 2028 and 2029. Factory investments greenlit today determine what manufacturing capacity exists by 2030. The gap between investment decision and operational capacity is two to four years. The consequences of 2025’s pullback will not be visible until the late 2020s.

Why. Trade policy instability is the most cited factor. On Friday, the Supreme Court struck down IEEPA tariffs in a 6-3 ruling, dropping the effective U.S. tariff rate from 16.9% to 9.1% per Yale Budget Lab analysis. Within hours, the administration imposed a new global tariff under Section 122 of the Trade Act of 1974, escalating it from 10% to 15% the following day. Section 122 caps presidential tariff authority at 150 days and 15% without Congressional approval, meaning the replacement tariff expires by mid-July 2026. Section 301 tariffs on Chinese batteries (exceeding 65%) and recently finalized duties on Chinese battery-grade graphite remain untouched by the ruling.

Even in a market where deployment economics are favorable, few manufacturing executives will commit billions to a domestic factory when the tariff structure can change before the foundation is poured.

The financing vacuum extends beyond tariffs. Breakthrough Energy wound down its Catalyst fund, the arm dedicated to financing first-of-a-kind clean technology projects. Latitude Media called the closure “a huge blow” for the cleantech sector, noting that Catalyst was one of the only vehicles willing to underwrite the concessionary risk of bridging technologies from demonstration to commercial deployment. With DOE loan programs under political uncertainty and traditional project finance unwilling to touch novel technology risk, the path from demonstration to commercial scale is narrowing.

The counterpoint. Deployment is increasingly decoupled from federal policy at the project level. A Xendee survey of more than 150 industry professionals reinforces this: 81% of those building multi-resource microgrids have active projects under development, compared with 48% for simpler one-to-two-technology systems. Between 70% and 75% did not rank federal funding loss as a top concern. Battery storage demand is up 12% in forward project plans, per the same survey.

The structural explanation is straightforward. Customer economics drive deployment decisions on three-to-seven-year payback horizons. Factory investments require policy stability over ten-to-twenty-year capital recovery periods. Tariff volatility disrupts the second without touching the first.

The result is a country that deploys more batteries than ever while the industrial base to manufacture them contracts. If domestic factory investment continues its decline, import dependence does not disappear; it shifts addresses.

The 2025 record is real. It is also the last year whose deployment figures fully reflect the investment climate of the IRA’s first two years. What the 2027 and 2028 numbers look like depends on factory commitments and interconnection applications that, as of Q4 2025, are arriving at their lowest rate in half a decade.
