An IRA energy credit bridge advances against expected proceeds from a §6418 transfer of §48 ITC or other eligible energy credits. The bridge funds at construction or installation start; take-out occurs at credit transfer to the buyer (typically post-placed-in-service when credit eligibility crystallizes).
Bridge mechanics and the IRA-driven energy capital stack
Tax credit programs change with IRS, Treasury, NPS, and CDFI Fund guidance. This page is sponsor-POV process commentary, not tax or legal advice. Engage tax counsel and a tax-credit syndicator for every transaction before relying on the mechanics described.
Eligible energy credits: §48 (energy investment tax credit including solar, wind, geothermal, EV charging, battery storage), §45 (production tax credit), §48E (technology-neutral ITC, post-2024), §45L (energy-efficient new homes), §45X (advanced manufacturing), and others. Each program has its own eligibility, basis calculation, and bonus-credit add-on rules (domestic content, energy community, low-income community).
Bridge structure: a project secures a transfer agreement (or a binding commitment letter) from a credit purchaser at a defined cents-per-credit price. The bridge lender advances a percentage of the expected transfer proceeds (typically 70% to 85%) at construction start or at equipment installation. Pricing reflects bridge debt fund or specialty bank rates plus bonus risk premium for credit-eligibility uncertainty.
Take-out sequencing: the credit transfer typically occurs after the project's placed-in-service date, when credit eligibility is finalized and the credit purchaser is comfortable executing the transfer. Bridge loan repayment occurs at the transfer-proceeds funding event, often within 30 to 90 days of placed-in-service.
Coordination with senior debt: on a CRE energy add-on (rooftop solar on industrial, EV charging on retail), the senior CRE debt sits on the underlying real estate. The energy improvement and its credit financing typically sit at a separate SPE or are subject to a defined intercreditor with the senior CRE lender. Bonus credits (domestic content, energy community) add complexity to the basis calculation but typically don't change the bridge structure.
Compliance and cost-certification: the credit purchaser will require a cost certification (typically by a qualified third-party engineer or accountant) before funding the transfer. The certification defines the eligible basis and the credit amount. Errors in basis calculation can reduce the transfer proceeds and create a shortfall against the bridge balance.
Sponsor playbook: at project planning, compare bridge financing economics across multiple bridge lenders (specialty bank vs. dedicated bridge fund) and credit transfer pricing across multiple credit purchasers. Both markets are competitive and fragmented; pricing variance can be meaningful. Coordinate the bridge term sheet with the transfer agreement timing to avoid funding gaps.
