Complete guide to earning the 10% domestic content bonus by using American-made steel, iron, and manufactured products in renewable energy projects.
Timeline: Begin domestic content planning 12-18 months before procurement.
Actions: - Identify domestic manufacturers for all major components - Request certifications, capacity information, and pricing - Negotiate terms and establish relationships before finalizing project design - Build domestic content requirements into RFPs and supplier contracts
Benefit: Early engagement allows time to qualify suppliers, negotiate pricing, and ensure availability before construction begins.
Requirement: All domestic content claims must be supported by written manufacturer certifications.
Best Practices: - Request certifications at time of purchase order (not after delivery) - Use standardized certification templates to ensure consistency - Require certifications to be signed by authorized company representatives - Include certifications as a condition of payment - Verify certifications against public information (e.g., facility locations, ownership records)
Avoid: Relying on verbal assurances, marketing materials, or “Made in USA” labels without underlying certifications.
System: Implement cost tracking system that segregates costs by category (manufactured products, steel/iron, labor, etc.).
Best Practices: - Assign cost codes to purchase orders and invoices for domestic vs. foreign content - Track costs in real-time during construction (not retroactively) - Maintain detailed bills of materials with cost allocations - Update domestic content percentage calculations monthly - Identify variances and corrective actions early
Benefit: Accurate cost tracking ensures you know whether project qualifies before placed-in-service date, allowing time to address shortfalls.
Timing: Engage independent engineer during procurement or construction phase (not after placed in service).
Scope: - Review all manufacturer certifications - Verify manufacturing locations and processes - Calculate domestic content percentage - Verify FEOC compliance (for 2027+ projects) - Provide formal report and opinion letter
Cost: Budget $25,000 to $100,000+ depending on project size and complexity.
Benefit: Third-party verification strengthens tax credit claims, supports IRS audit defense, and identifies deficiencies while there’s still time to correct.
Costs to Include in Project Budget: - Domestic content premium costs (10-20% equipment cost increase) - Independent engineer fees ($25K-$100K+) - Legal and tax advisor fees for structuring and compliance - Additional procurement and supply chain management costs - Documentation and tracking system costs
Typical Total Cost: 12-25% increase in project costs, partially offset by 10% credit increase.
Risks: - Limited U.S. manufacturing capacity for certain components - Extended lead times for domestic equipment (3-12 months longer than imports) - Supply chain disruptions affecting domestic manufacturers - Price volatility for domestic products
Mitigation Strategies: - Order domestic equipment early with long lead times - Identify backup domestic suppliers - Build schedule buffer for domestic supply chain delays - Lock in pricing with fixed-price contracts or options - Monitor U.S. manufacturing capacity expansions and new market entrants - Consider phased project delivery to align with domestic supply availability
Solar Manufacturing Expansion: - U.S. solar manufacturing capacity is expanding rapidly due to IRA incentives - First Solar, Qcells, Hanwha, Silfab, and others are building or expanding U.S. facilities - By 2026-2027, U.S. solar panel manufacturing capacity is projected to reach 30+ GW annually - Increased capacity will reduce cost premiums and improve availability
Battery Manufacturing Expansion: - Tesla, LG Energy Solution, Panasonic, and others are expanding U.S. battery cell and module production - Department of Energy grants and loans supporting battery manufacturing - By 2027-2030, U.S. battery cell manufacturing capacity is projected to significantly increase - However, FEOC-free (non-Chinese) battery supply chains remain limited and costly
Wind and Other Technologies: - GE, Vestas, and Siemens Gamesa maintain U.S. wind manufacturing facilities - Inverter, transformer, and electrical equipment manufacturers expanding U.S. operations - Steel and racking manufacturers investing in domestic capacity
Outlook: Domestic content will become easier and more cost-competitive over time as U.S. manufacturing capacity scales up.
Impact on Supply Chains: - Starting January 1, 2027, projects must exclude FEOC (Chinese, Russian, Iranian, North Korean) content - Solar: Chinese solar cells and wafers dominate global supply; non-FEOC alternatives are limited - Batteries: Chinese battery cells dominate; South Korean, Japanese, and U.S. alternatives are ramping but insufficient - Critical Minerals: China controls lithium, cobalt, and rare earth processing; alternative sources developing slowly
Compliance Challenges: - Extensive supply chain tracing required to identify FEOC involvement - Cost premiums for FEOC-free components will increase (20-40%+) - Manufacturers must certify FEOC compliance, adding complexity and liability
Strategic Response: - Developers are beginning to qualify FEOC-free suppliers now - Industry advocating for IRS guidance on FEOC tracing requirements and safe harbors - Some developers considering accelerating projects to 2026 placed-in-service to avoid FEOC restrictions
Outlook: 2027 will be a challenging transition year. Expect limited FEOC-free supply, high cost premiums, and potential project delays. Situation will improve gradually as non-FEOC manufacturing capacity scales.
Phase-In Schedule Reminder: - 2023-2024: 40% - 2025: 45% - 2026: 50% - 2027+: 55%
Impact: - Projects placed in service in later years face higher thresholds - Combined with FEOC restrictions (2027+), achieving 55% will be extremely challenging - Developers may strategically accelerate projects to achieve earlier placed-in-service dates
Planning Considerations: - Model domestic content percentage under current and future thresholds - Consider project phasing to achieve earlier placed-in-service dates - Monitor U.S. manufacturing capacity growth to assess future feasibility
Federal Incentives: - IRA includes Advanced Manufacturing Production Credits (AMPC, Section 45X) for domestic manufacturing of solar, wind, battery, and critical mineral components - Department of Energy grants and loan programs supporting U.S. clean energy manufacturing - Defense Production Act invoked to support domestic critical mineral processing
Industry Response: - Billions of dollars in private investment flowing to U.S. manufacturing facilities - New entrants and established players expanding U.S. operations - Industry coalitions advocating for additional policy support and supply chain development
Outlook: Federal policy and industry investment are aligned to build robust U.S. clean energy supply chains. Domestic content qualification will become more feasible and cost-effective over the next 5-10 years.
