Green energy tax credits survived OBBBA: Here is what buyers and sellers need to know in 2026

Key highlights:

• • • Tax credit transferability survived intact— The OBBBA preserved Section 6418 transferability rules despite earlier proposals to sunset or repeal them.

    • AI-driven data center boom may revive renewable energy tax credits— With data centers projected to consume 12% of all US energy by 2028, large operators have strong incentives to advocate for preserving and expanding renewable tax credits to meet massive energy demands through solar, geothermal, and battery storage solutions.

    • 2026 market conditions favor buyers due to supply-demand imbalance—Increased supply of tax credits (particularly Section 45Z clean fuel production credits) combined with reduced buyer competition from provisions like Section 174 and bonus depreciation has created advantageous pricing.

At the start of the current Trump administration, green energy tax credits were expected to be slashed or disappear altogether. In reality, significant changes emerged instead of ceasing to exist. More specifically, the One Big Beautiful Bill Act (OBBBA), passed in July 2025, kept the transferability rules around green energy tax credits intact.

As a result, the market for these credits remains robust in 2026 and 2027, says Brandon Hill, an energy tax authority and principal at accounting firm CliftonLarsonAllen (CLA). In addition, multiple credits still have runway, and near-term dynamics in 2026 may favor buyers.

OBBBA’s changes result in shifts in marketplace conditions

When the OBBBA bill passed, the specifics revealed a more optimistic picture than many understand. According to Hill, specific examples include:

• • Wind and solar projects — Developers that begin construction by July 4, 2026, still have a four-year window to complete their projects and still claim credits. Even projects that miss this construction deadline can qualify if they’re placed in service by December 31, 2027.
  • Clean fuel production credits — Clean fuel production credits, detailed in OBBBA’s Section 45Z, received an extended runway through 2029.
  • Tax credit transferability — The tax credit transferability aspect under Section 6418 remained whole, despite previous versions of the bill proposing either a sunset date or outright repeal of transferability. This fact provides a level of marketplace certainty that can act as critical liquidity for developers that typically lack the tax liability to use credits themselves.

In addition, the legislation altered the buyer and seller environment. Provisions including OBBBA’s Section 174 and bonus depreciation generated additional deductions for certain companies, and as a result, reduced those companies’ 2025 corporate tax liability. Simultaneously, Section 45Z clean fuel production tax credits came into force and created a supply-demand imbalance that favors buyers.

Overall, in the latter half of 2025, Hill describes the marketplace as favorable for buyers because of an increased supply of tax credits that were for sale previously with fewer buyers. Into 2026 and beyond, both developers and corporate buyers still have significant opportunities to participate in the tax credit marketplace, explains Hill.

AI-related data center demand may spur new proposals for renewables tax credits

The explosive proliferation of data centers because of the growing AI demand across the United States may become the unexpected champion for renewable energy tax credits. Hundreds of facilities are currently under construction, and the energy demand implications are staggering. In fact, the U.S. Department of Energy projects that by 2028, data centers will consume 12% of all US energy.

Renewable energy technologies are emerging as essential solutions to meet these demands. Solar power, as a tried-and-true technology, offers ideal supplementation for data center operations; and geothermal heating and cooling systems directly address the massive temperature control challenges these facilities face. Perhaps most significantly, battery storage is rapidly becoming standard operating procedure, with both grid-based and solar-array-tied battery systems providing critical backup power.

These developments carry substantial policy implications. In fact, large data center operators have incentives to become vocal advocates for preserving and expanding renewable tax credits, says Michael DePrima, a leader in federal tax strategies at CLA. “We want our AI, we want our cloud-based services. To do that… we need massive data centers and massive computing demands,” DePrima explains. “And that in turn requires massive amounts of energy consumption, which renewables can certainly supplement.” This, in turn, creates the potential for a renewable energy tax credit “comeback” within two to three years, he adds.

Guidance for buyers and sellers

Looking ahead to 2026 and beyond, both buyers and sellers of renewable energy tax credits should recognize that significant opportunities remain despite regulatory changes. More specifically:

For buyers — Buyers should act now to capitalize on favorable market conditions. With increased credit supply and reduced buyer competition due to provisions like Section 174 and bonus depreciation, pricing has become more advantageous. Buyers of renewable energy tax credits should consider structuring 2026 transactions to directly offset estimated tax payments throughout the year, thereby improving cash flow by making payments to sellers rather than the IRS. Financial institutions remain particularly well-positioned as buyers, as many have explored tax credit carryback opportunities to increase their tax savings even further.

For sellers and developers — Renewable energy tax credits sellers and energy project developers can use tax-credit monetization as a critical component of project financing because the ability to convert credits into immediate cash proceeds is essential for paying down debt and funding new projects. Despite initial concerns, substantial opportunities remain with credits outlined in Sections 45Z, 45X, 48E, and 45Y which are transferable and viable through 2029 and beyond.

In either case, tax credit transferability under Section 6418 offers key opportunities in the marketplace. Whether buyers are looking to reduce their corporate tax burden while supporting clean energy goals, or developers are seeking to monetize renewable projects — tax credits offer incentives to move forward.
