Key Updates on Investment Tax Credits for Clean Energy
- The IRS confirmed new rules for investment tax credits related to clean energy on Wednesday, which include provisions for biogas. These updated guidelines benefit renewable natural gas projects refining biogas from sources like landfills and organic waste, according to industry leaders.
- Initial drafts of the credit language released in November faced criticism for excluding parts of facilities used for upgrading biogas to RNG. Organizations such as the American Biogas Council and Coalition for Renewable Natural Gas expressed concerns over the draft language.
- The American Biogas Council stated that the final update is positive news for RNG developers, who are expected to apply for these credits for projects initiated this year.
Insights on the Incentives
The Section 48 Investment Tax Credits were influenced by the Inflation Reduction Act, passed in 2022. This legislation also includes credits for various clean energy initiatives, such as hydrogen storage and offshore wind advancements.
Patrick Serfass, executive director of the American Biogas Council, praised the Treasury Department for crafting rules that accurately reflect how biogas systems operate. He noted that these regulations will provide developers with confidence regarding the eligibility of their project investments for available clean energy tax credits.
Notably, the new rules now recognize equipment that converts raw biogas into high-quality natural gas as an essential part of projects, a change from the previous stance. This adjustment simplifies the tax credit application for regular RNG projects and clarifies that developers of RNG facilities can receive credits even if the gas collection system is owned by a different company.
Developers must begin construction on their projects before the end of 2024 to qualify for the credit. This start date offers some flexibility; developers might qualify if they have ordered equipment or invested 5% of the total cost this year, according to Lauren Collins, a tax law attorney specializing in renewable energy projects.
While some developers have already started construction anticipating the finalized credit guidelines, the timing may now push others to expedite plans to launch new projects before the year concludes. Collins highlighted that this rush is a significant concern for her clients, who are now faced with tight timelines.
