Executive Perspective

Disclosure: Advance rates, deployment timelines, and financing structures referenced on this page are illustrative and represent typical parameters for qualified positions. Actual terms are subject to lender review, collateral assessment, and borrower-specific underwriting. This content does not constitute an offer of credit or financial advice. See our full disclosures.

IRS Notice 2023-29 governs the bonus credit adders available under Section 48 of the Internal Revenue Code, which provides investment tax credits for qualified energy property. Solar, battery storage, and fuel cell projects in Kentucky commonly qualify under this provision.

The Inflation Reduction Act of 2022 fundamentally restructured ITC monetization. Credits are now transferable to unrelated third parties under IRC Section 6418. The DOE's Solar Investment Tax Credit guide provides a plain-language overview of the credit structure and eligibility requirements applicable to Kentucky energy operators.

Transferability eliminated the dependency on tax equity partnerships. Bridge lenders now advance directly against the committed purchase agreement value before project completion.

The Fiduciary Problem

Energy project developers face a liquidity cliff between construction completion and credit monetization. Placed-in-service determinations can lag construction by 60 to 90 days.

Traditional construction lenders do not advance against future tax credit receivables. Their underwriting models treat credit proceeds as contingent, not contractual.

A committed credit purchase agreement changes this calculus. The agreement converts a contingent credit stream into a contractual payment obligation from a named counterparty.

Bridge lenders underwrite the counterparty credit quality, not the tax credit itself. An investment-grade buyer commitment supports advance rates of 70 to 80 percent of purchase price.

Operators that fail to execute purchase agreements before construction close lose the bridge window. Retroactive structuring after placed-in-service offers less favorable terms.

Regulatory Framework

Section 48 credits attach to qualified energy property placed in service during the taxable year. Eligible property includes solar panels, battery storage systems, and qualified fuel cells.

The IRA added energy community and domestic content adders. A Kentucky project in a qualifying energy community can access up to a 10-percentage-point ITC adder.

Treasury Regulation Section 1.48-9 defines eligible basis for ITC calculation. Basis includes tangible property costs, installation, and interconnection expenses allocated to eligible components.

Section 6418 transferability elections must be filed with the project's annual tax return. Buyers cannot further transfer purchased credits, and recapture risk attaches to the original transferor for five years.

Bridge lenders typically require title insurance against recapture risk as a loan condition. Operators must budget for this cost as part of the total financing package.

Regulatory Reference
IRC Section 6418 — Transferability of Certain Credits. Enacted under IRA of 2022. Permits eligible taxpayers to elect to transfer all or a portion of an eligible credit to an unrelated taxpayer. The transferee pays cash for the credit; payment is not treated as taxable income to the transferor. Bridge advance underwriting treats the purchase agreement as the primary collateral instrument.

Midpoint · Structural Analysis
A committed purchase agreement is the foundational document for any Section 48 bridge facility.
The regulatory framework has matured. Bridge underwriters now assess buyer creditworthiness and eligible basis certification as the two primary approval gates for Kentucky ITC bridge facilities.

Case Simulation 20 MW Solar + Storage Project — Hardin County, KY
$8.4M
ITC Credit Value (40% of Basis)
$6.3M
Bridge Advance (75% of Agreement)
16 Mo.
Bridge Tenor to Credit Settlement

A Hardin County developer completes a 20 MW solar-plus-storage facility with $21M in eligible basis. The project qualifies for a 40% ITC through combined base credit and energy community adders.

The developer executes a credit purchase agreement with an investment-grade utility buyer. The purchase price is $8.4M, representing the full 40% credit against eligible basis.

A bridge lender advances $6.3M at 75% of the purchase agreement value. These funds retire a portion of construction debt while the developer awaits placed-in-service determination.

Sixteen months after construction close, the IRS processes the transferability election. The buyer remits $8.4M; the developer retires the bridge and pockets the $2.1M net spread over the advance.

Prevailing Wage and Apprenticeship Requirements for 30% ITC

The IRA's 30% ITC rate requires compliance with prevailing wage and apprenticeship (PWA) standards throughout construction and for five years post-placed-in-service. Projects that fail PWA requirements revert to the 6% base rate.

Prevailing wage compliance requires that all laborers and mechanics on the project be paid wages not less than the applicable Davis-Bacon Act rates for the type of work performed in the geographic area. Kentucky construction wage rates are published by the Department of Labor.

Documentation requirements for PWA compliance include certified payroll records for all contractors and subcontractors, signed compliance certifications from the general contractor, and a compliance audit completed before the placed-in-service date. Bridge lenders review PWA documentation as a condition of advance at the 30% rate.

Apprenticeship requirements mandate that a defined percentage of labor hours on the project be performed by qualified apprentices from registered programs. The applicable percentage increases through 2026 under IRA phase-in provisions.

Failure to satisfy PWA requirements reduces the ITC from 30% to 6%—a 24-percentage-point reduction that dramatically changes bridge advance economics. Lenders underwrite against PWA compliance documentation, not operator assurances.

Kentucky projects qualifying for energy community adders (potential additional 10%) must document both PWA compliance and the underlying energy community designation. The combined 30% + 10% structure requires clean documentation of both layers before lenders advance at enhanced rates.

Safe Harbor Strategies for Kentucky Energy Projects

IRS safe harbor rules allow project developers to lock in a specific ITC credit year before physical completion of the project. Two pathways exist: the 5% cost incurrence test and the physical work test.

The 5% cost incurrence test requires that the developer incur at least 5% of the total project cost in the qualifying tax year. Prepayments, binding contracts, and physical purchases all qualify as cost incurrence for safe harbor purposes.

The physical work test requires that the developer commence physical work of a significant nature on the project site. Preliminary site clearing and foundation work typically meet this standard; manufacturing components off-site may also qualify under specific IRS guidance.

Kentucky energy projects applying safe harbor must maintain documentation of the qualifying cost incurrence or physical work event. Bridge lenders will request this documentation as evidence that the credit year is locked before advancing against a forward purchase agreement.

Safe harbor is particularly valuable for projects that span multiple tax years during construction. A project beginning construction in 2025 that safe-harbors at the 30% credit rate locks in that rate even if placed-in-service occurs in 2026 when rates may be lower.

Operators who miss the safe harbor window must assess whether the current-year credit rate supports their project economics. Bridge facilities should be sized against the confirmed applicable credit rate, not an anticipated rate that has not been locked through safe harbor documentation.

Recapture Risk Management in Section 48 Bridge Facilities

Section 50 of the IRC imposes ITC recapture if qualifying energy property is disposed of or ceases to be investment credit property within five years of placed-in-service. The recapture amount decreases by 20% per year over the five-year window.

Recapture risk attaches to the original credit transferor even after the credit has been sold to a third-party buyer. The transferor must monitor project use and disposition throughout the five-year recapture period and indemnify the buyer if recapture occurs.

Bridge lenders require recapture indemnity agreements as a standard loan condition. The indemnity obligates the borrower to reimburse the lender for any recapture-related loss that reduces the net proceeds available to repay the bridge.

Recapture insurance from specialty carriers provides an alternative or supplemental layer of recapture protection. Annual premiums typically run 0.3% to 0.8% of insured credit value; insurers require underwriting packages including project completion certificates, placed-in-service documentation, and title chain confirmation.

Partial dispositions—such as sale of a portion of the project assets—trigger partial recapture proportional to the disposed value. Operators planning future asset sales within the recapture window must model the recapture impact before committing to bridge facilities sized at the full credit value.

Kentucky operators who anticipate refinancing the project during the recapture window must confirm that the refinancing does not constitute a disposition or change in qualified use triggering recapture. Tax counsel review is required before any refinancing transaction within the five-year recapture period.
