IRA Transferability Is a Structural Market Innovation

FEOC (Foreign Entity of Concern) sourcing restrictions on battery components are now fully in force for projects beginning construction in 2026 or later, with expanded thresholds covering ownership, control, or jurisdiction ties to China, Russia, Iran, and North Korea. The practical result: Chinese manufacturers face a potential tariff range of 40.9%–82.4% in 2026, combined with non-negotiable UL 9540/9540A fire-testing certification requirements and sub-two-second frequency response mandates in leading states like California. This is squeezing out Chinese cell supply from the U.S. grid-scale storage market faster than most supply chain timelines can accommodate. Developers who didn't complete safe-harbor positioning before end-2025 now face either domestic content compliance costs or ITC recapture risk over a 10-year horizon. The supply chain crunch is real and will likely widen the cost gap between U.S. and European BESS deployment in the near term. Source
