The Section 48E Investment Tax Credit (ITC)
introduced under the Inflation Reduction Act (IRA) represents a significant shift compared to previous tax credits for energy storage and clean electricity facilities. Here are the key differences:
Technology-Neutral Credit Including Energy Storage
- Section 48E is a newly established, technology-neutral tax credit that applies broadly to facilities generating clean electricity, which explicitly includes energy storage technologies placed in service after December 31, 2024.
- This contrasts with prior ITCs which were more narrowly focused on renewable generation technologies (e.g., solar under Section 48) and did not explicitly include stand-alone energy storage without paired generation.
Credit Percentage and Wage Requirements
- The Section 48E credit is generally 6% of the qualified investment but can increase to 30% if the taxpayer meets prevailing wage and apprenticeship requirements during construction or alteration of the facility.
- This wage-linking feature is aligned with the IRA’s emphasis on labor standards, which was less prominent in earlier credits.
Eligibility and Ownership Rules
- Section 48E allows taxpayers to claim credits for energy storage technology as an independent unit or as part of a qualified clean electricity facility, with the credit amount based on ownership interest in the unit.
- Previous credits often required the energy storage system to be directly associated with a renewable generation facility or did not recognize fractional ownership interests for credit purposes.
Direct Pay and Transferability
- Section 48E offers direct pay eligibility to tax-exempt entities such as Indian Tribal governments, rural co-ops, and states, who previously could not benefit directly from ITCs because they had no tax liability.
- It also allows for transferability of credits, meaning the credits can be sold or transferred, which increases their monetization potential. Earlier ITCs had more limited or no transferability provisions.
Integration and Stackability Rules
- The new Section 48E credit replaces the former ITC for facilities generating electricity from renewable sources after its sunset in 2024.
- There is a prohibition on claiming both the Section 48E ITC and the Production Tax Credit (PTC) under Section 45Y for the same facility.
- The credit amount must be reduced if tax-exempt bonds contribute to financing, adopting similar stackability rules found in prior tax credits, but with adjustments fitting the new IRA context.
Energy Community Bonus
- Section 48E includes an additional bonus credit for projects located in designated “energy communities” (e.g., areas affected by fossil fuel employment declines), which was not a feature of earlier ITCs.
Summary Table of Differences
| Feature | Section 48E ITC | Previous Energy Storage / Renewable ITCs |
|---|---|---|
| Technology scope | Technology-neutral including energy storage | Mainly renewable generation; limited for storage alone |
| Credit rate | 6%, up to 30% with prevailing wage/apprenticeship | Up to 30%, wage rules less emphasized |
| Direct pay eligibility | Yes, for tax-exempt orgs, tribes, co-ops | Generally no direct pay for tax-exempt entities |
| Transferability | Yes | Limited or no transferability |
| Ownership rules | Fractional interest allowed for credit | Typically required full ownership of facility |
| Stackability with PTC | Cannot claim 48E and 45Y PTC for same facility | Some earlier credits allowed stacking |
| Energy community bonus | Yes | No |
In essence, Section 48E modernizes and expands the investment tax credit framework to more inclusively cover energy storage technologies, introduce labor standards, broaden accessibility through direct pay and transferability, and include geographic bonus incentives, marking a broader and more flexible policy tool for clean energy investment than prior energy storage credits.
