Energy-Storage.news proudly presents this webinar, sponsored by Intertek CEA, examining the impact of foreign entity of concern (FEOC) restrictions on US battery storage procurement and supply chain management.
As battery energy storage system (BESS) deployment accelerated across the United States, developers faced a new procurement reality: FEOC restrictions introduced under the One Big Beautiful Bill Act (OBBBA) made supply chain due diligence central to securing – and protecting – the Investment Tax Credit (ITC).
For BESS developers, the stakes were significant. Unlike solar and wind, where tax credits were being phased down more aggressively, storage remained highly dependent on the ITC. At the same time, the battery supply chain remained heavily concentrated in China across raw materials, processing, and cell manufacturing — creating growing complexity around sourcing strategies and compliance documentation.
As developers worked to secure compliant supply, they had to navigate evolving guidance, increased scrutiny around ownership and effective control, and uncertainty around what evidence would ultimately be required to support FEOC compliance.

This webinar examined how FEOC requirements were reshaping the US BESS market from both a policy and practical implementation perspective. Experts from Intertek CEA broke down the latest developments surrounding FEOC restrictions and Material Assistance Cost Ratio (MACR) thresholds, as well as key areas where uncertainty remained around topics such as effective control, intellectual property, and grandfathering provisions.
Beyond policy, the session also focused heavily on the practical realities developers and buyers were facing in the market. Attendees gained insight into how Intertek CEA was assessing battery suppliers in practice, what documentation and evidence could support compliance efforts, and how to navigate emerging supplier transparency and due diligence challenges.
Key discussion topics included:
• The latest FEOC and OBBBA developments impacting BESS projects
• How MACR requirements affected battery sourcing strategies
• Ownership and effective control considerations in supplier evaluations
• Common documentation gaps and supplier transparency challenges
• Practical approaches for assessing supplier compliance claims
• Key supplier due diligence considerations for developers and buyers
Speakers:
