Foreign Entity of Concern (FEOC) restrictions are federal regulations that prohibit energy storage projects from receiving Investment Tax Credits (ITC) or Production Tax Credits (PTC) if their supply chains include components, critical minerals, or controlling interests from designated foreign adversaries—primarily China, Russia, Iran, and North Korea. For battery energy storage systems (BESS), these rules create binary eligibility: projects meeting FEOC compliance thresholds qualify for tax credits worth 30% or more of project costs, while any non-compliant component can disqualify the entire project. Beginning in 2026, storage projects must demonstrate at least 55% of manufactured product costs come from non-FEOC sources, rising to 75% by 2030. Non-compliance triggers not only loss of credits but potential 100% recapture over a 10-year period. Empower IT provides FEOC-compliant energy storage solutions with complete supply chain documentation, enabling customers to secure full ITC eligibility while eliminating regulatory risk.

What Is a Foreign Entity of Concern?
A Foreign Entity of Concern (FEOC) is any organization owned, controlled, or subject to the jurisdiction of designated foreign adversaries that pose national security risks to the United States. The regulatory framework identifies four “covered nations”: the People’s Republic of China (PRC), the Russian Federation, the Democratic People’s Republic of North Korea, and the Islamic Republic of Iran.
Under guidance from the Department of Energy and Department of Treasury, an entity qualifies as an FEOC through several pathways: incorporation or headquarters in a covered nation, 25% or more government ownership through voting rights, board seats, or equity interest, designation on federal sanctions lists, or effective control through licensing agreements or contracts with covered nation entities.
| FEOC Category | Definition |
|---|---|
| Specified Foreign Entity (SFE) | Directly owned/controlled by covered nation government, on DoD prohibited list (CATL, BYD, Gotion, EVE, Envision, Hithium), or on OFAC sanctions list |
| Foreign-Influenced Entity (FIE) | 25% or more ownership by single SFE, 40% combined ownership by multiple SFEs, or SFE ability to appoint board members or executive officers |
| Effective Control Entity | Any entity controlled through licensing agreements, contracts, or technology arrangements that grant operational influence to covered nation parties |
| Covered Nation Entity | Entity incorporated in, headquartered in, or performing relevant manufacturing/processing activities within China, Russia, Iran, or North Korea |
The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, significantly expanded FEOC restrictions beyond the original electric vehicle provisions in the Inflation Reduction Act. The expanded rules now apply to six major clean energy tax credits, with the most significant impact on battery energy storage systems claiming the Section 48E Investment Tax Credit.
Which Tax Credits Are Affected by FEOC Rules?
FEOC restrictions apply to six clean energy tax credit programs, each with varying compliance requirements and enforcement mechanisms. For energy storage projects, the most critical are the Section 48E Clean Electricity Investment Tax Credit and the Section 45X Advanced Manufacturing Production Credit.
| Tax Code | Credit Type | Application | FEOC Impact |
|---|---|---|---|
| Section 48E | Clean Electricity ITC | Energy storage deployment | 30% ITC at risk, 10-year recapture period |
| Section 45Y | Clean Electricity PTC | Power generation | Production credits denied if FEOC materials used |
| Section 45X | Advanced Manufacturing | Component production | Manufacturing credits denied for FEOC inputs |
| Section 45Q | Carbon Capture | CO2 sequestration | Credit denied if taxpayer is PFE |
| Section 45U | Nuclear Production | Nuclear power | Credit denied if taxpayer is PFE |
| Section 45Z | Clean Fuels | Fuel production | Credit denied if taxpayer is PFE |
Critical Risk: The Section 48E ITC carries a 100% credit recapture penalty over a 10-year period if any payments are made to Specified Foreign Entities that exercise effective control after the project is placed in service. This transforms FEOC compliance from a one-time verification into a decade-long operational requirement.
What Are the Material Assistance Compliance Ratios?
Projects claiming Section 48E or Section 45Y credits must demonstrate that a minimum percentage of manufactured product costs come from non-FEOC sources. These Material Assistance Compliance Ratios (MACR) vary by technology type and increase annually, creating progressively stricter requirements through 2030.
For energy storage technologies, the compliance thresholds are significantly higher than for solar or wind projects, reflecting the concentrated role of covered nations in global battery supply chains. Projects must calculate the ratio of compliant costs to total direct costs for all manufactured products and components.
| Technology | 2026 | 2027 | 2028 | 2029 | 2030+ |
|---|---|---|---|---|---|
| Energy Storage (48E/45Y) | 55% | 60% | 65% | 70% | 75% |
| Solar/Wind (48E/45Y) | 40% | 45% | 50% | 55% | 60% |
| Battery Components (45X) | 60% | 65% | 70% | 80% | 85% |
| Inverters (45X) | 50% | 55% | 60% | 65% | 70% |
| Critical Minerals (45X) | 0% | 0% | 0% | 0% | 25% |
The IRS is directed to publish safe harbor tables by December 31, 2026 to simplify compliance calculations. Until then, taxpayers may use existing domestic content safe harbor tables from IRS Notice 2025-08 or obtain supplier certifications verifying non-FEOC status. Suppliers providing false certifications face penalties of 10% of any resulting tax underpayment or $100,000, whichever is greater.
Which Battery Manufacturers Are Prohibited Foreign Entities?
The OBBBA explicitly designates several major battery manufacturers as Specified Foreign Entities based on their inclusion in the National Defense Authorization Act for Fiscal Year 2021 as entities ineligible for Department of Defense contracts. Components from these manufacturers automatically disqualify projects from FEOC compliance.
| Manufacturer | Headquarters | Market Position |
|---|---|---|
| CATL (Contemporary Amperex) | Ningde, China | World’s largest battery manufacturer (~37% global market) |
| BYD Company | Shenzhen, China | Second largest battery manufacturer, major EV producer |
| Gotion High-Tech | Hefei, China | LFP cell manufacturer, US facility in Illinois |
| EVE Energy | Huizhou, China | Major cylindrical and prismatic cell producer |
| Envision Energy (AESC) | Shanghai, China | Former Nissan battery division, grid storage focus |
| Hithium Energy Storage | Xiamen, China | Utility-scale BESS manufacturer |
Supply Chain Reality: These six manufacturers collectively represent the majority of global battery cell production. China processes over 70% of global lithium, 85% of cobalt, and 90%+ of graphite—creating FEOC exposure even for batteries assembled outside covered nations if upstream materials were processed by FEOC entities.
What Are the Financial Consequences of Non-Compliance?
FEOC non-compliance creates immediate and long-term financial consequences that can fundamentally alter project economics. The most severe impact is the complete disqualification from the Section 48E ITC, which typically represents 30% of eligible project costs for standalone battery storage.
| Consequence | Impact | Duration |
|---|---|---|
| ITC Disqualification | Loss of 30%+ tax credit on project costs | Immediate upon determination |
| Credit Recapture | 100% repayment of previously claimed ITC | 10-year liability period |
| Transfer Prohibition | Cannot sell/transfer credits to third parties | Permanent for affected project |
| Bonus Adder Loss | Forfeit domestic content (+10%) and energy community (+10%) bonuses | Immediate |
| Financing Impact | Tax equity investors require extensive warranties and indemnification | Project lifecycle |
| Supplier Penalties | 10% of tax underpayment or $100,000 for false certifications | 6-year assessment window |
The 10-year recapture provision is particularly significant for energy storage projects. If at any point during the decade following project commissioning the owner makes payments to Specified Foreign Entities that exercise “effective control”—including warranty services, replacement components, or software licensing—the entire ITC must be repaid to the Treasury. This transforms routine maintenance decisions into potential multi-million dollar compliance events.
How Can Projects Achieve FEOC Compliance?
Achieving FEOC compliance requires systematic due diligence across the entire supply chain, from raw material sourcing through final assembly. The compliance framework demands documentation at multiple levels: component origin verification, ownership structure analysis, and contractual review for effective control provisions.
Projects have several strategic pathways to compliance:
| Strategy | Approach | Considerations |
|---|---|---|
| Safe Harbor (Pre-2026) | Begin construction before January 1, 2026 | Exempt from material assistance rules; requires continuous construction progress |
| Non-FEOC Supply Chain | Source from compliant manufacturers | Higher cost; limited supplier options; requires full traceability |
| Domestic Manufacturing | Use US-manufactured components | Qualifies for domestic content bonus; verifiable compliance |
| Alternative Technology | Deploy non-lithium-ion storage | Solid-state, flow batteries, or other technologies with compliant supply chains |
| Allied Nation Sourcing | Source from friendly nations (Korea, Japan, EU) | Must verify upstream mineral processing is non-FEOC |
Documentation Requirement: Tax equity investors now demand unprecedented levels of supply chain documentation including: Tier 1, 2, and 3 supplier certifications, ownership structure verification, licensing agreement reviews, mineral traceability records, and ongoing compliance monitoring commitments. This documentation requirement has become a standard cost of doing business for FEOC-compliant projects.
Why Does Solid-State Technology Simplify FEOC Compliance?
Graphene-based solid-state energy storage technology offers a fundamentally different compliance profile than conventional lithium-ion batteries. By eliminating reliance on the lithium-ion supply chain—which is heavily concentrated in covered nations—solid-state systems can achieve FEOC compliance through supply chain architecture rather than complex component-by-component verification.
Empower IT’s ELDES (Electrostatic Long-Duration Energy Storage) technology provides several compliance advantages:
| Compliance Factor | Lithium-Ion Challenge | Solid-State Advantage |
|---|---|---|
| Cell Manufacturing | 90%+ global capacity in China | US-based production capability |
| Critical Minerals | China processes 70%+ lithium, 85%+ cobalt, 90%+ graphite | Alternative material inputs from compliant sources |
| BMS/Software | Many systems use Chinese-licensed IP | Proprietary US-developed technology |
| Supply Chain Depth | Tier 3-4 verification required | Simplified verification chain |
| Documentation | Complex multi-tier certification required | Comprehensive compliance package provided |
| Recapture Risk | 10-year exposure to supplier status changes | Stable compliance through technology architecture |
Beyond initial compliance, solid-state technology eliminates the 10-year recapture risk by removing dependence on FEOC-linked warranty services, replacement components, or software updates. The technology’s exceptional durability—500,000+ cycles with minimal degradation—means fewer replacement events that could trigger compliance review.
What Is the Timeline for FEOC Implementation?
FEOC implementation follows a phased timeline with critical deadlines that project developers must navigate carefully. Understanding these dates is essential for strategic planning around safe harbor provisions, construction timing, and compliance documentation requirements.
| Date | Milestone | Impact |
|---|---|---|
| July 4, 2025 | OBBBA signed into law, expanding FEOC restrictions | Rules enacted |
| Tax Year 2026 | SFE/FIE restrictions effective for all affected credits | Entity-level compliance required |
| January 1, 2026 | Material assistance rules apply to projects beginning construction | 55% threshold for storage |
| December 31, 2026 | IRS safe harbor tables must be published | Simplified calculations |
| July 2027 | 10-year recapture provision becomes effective for 48E | Long-term compliance begins |
| 2027-2030 | Annual 5% increase in MACR thresholds | Rising compliance bar |
| 2030+ | Storage threshold reaches 75%, battery components 85% | Maximum stringency |
Strategic Window: Projects that begin construction before January 1, 2026 are exempt from material assistance requirements (though still subject to entity-level SFE/FIE restrictions). This creates a limited window for projects to lock in eligibility under current rules. Safe harbor requires demonstrating continuous construction progress over four years.
