The second quarter of 2024 presented several significant developments in the renewable energy sector, particularly related to tax updates and regulations. The U.S. Department of the Treasury and IRS issued various rulings and guidance, such as finalizing regulations on prevailing wage and registered apprenticeship requirements for increased credits or deductions. Proposed rulemaking focused on clean electricity production and investment credits, while a supplemental NPRM addressed details of the clean hydrogen production tax credit. Additional guidance covered clean vehicle credits, clean fuel production tax credits, energy community bonus credits, and domestic content safe harbors. The IRS also provided updates on the inflation adjustment factors for the clean hydrogen credit and the Sustainable Aviation Fuel Tax Credit. Key cases, like Valero Marketing and Supply Co. v. United States, highlighted legal disputes related to alternative fuel mixture credits. The Holland & Knight Renewable and Alternative Energy Tax Team continues to monitor these developments closely, offering in-depth publications and guidance through various alerts. It is essential for industry professionals to stay informed about these changes to navigate the complex landscape of renewable energy taxation effectively.
