A bill to amend the Internal Revenue Code of 1986 to establish a tax credit for qualified combined heat and power system property, and for other purposes.
SB3531 would amend the Internal Revenue Code to create a new federal tax credit for “qualified combined heat and power system property” under a new section 48F. The credit would generally equal 10% of the basis of eligible combined heat and power (CHP) property placed in service during the taxable year, with potential 10 percentage-point increases for projects meeting domestic content requirements or located in an energy community. The bill also directs the Treasury Department to issue regulations and guidance, including recordkeeping and reporting rules, to administer the credit.
The bill defines eligible CHP property as systems that simultaneously or sequentially produce electricity or mechanical power and useful thermal energy, meet minimum efficiency and output thresholds, and begin construction on or after January 1, 2025. It excludes property in facilities already claiming the section 45 production tax credit, limits the credit for systems above certain capacity thresholds, and provides special rules for biomass-fueled systems. The bill also coordinates the new credit with existing tax provisions, including rehabilitation credits, energy credits, and other related sections of the tax code, and applies generally to property whose construction begins after December 31, 2024.
The bill would add a new energy-related business tax incentive to the Internal Revenue Code and make conforming amendments across several existing sections, including sections 38, 45L, 46, 48C, 50, and 59A. It would also clarify capacity determinations for certain energy credit rules and specify that the new credit applies to qualifying CHP property beginning construction after the effective date, with a separate coordination rule for property begun before January 1, 2025 but placed in service later. The primary affected parties would be taxpayers developing or investing in combined heat and power projects, especially industrial, commercial, and biomass-based facilities that can meet the bill’s efficiency, capacity, and domestic content or energy community requirements.
Based on the bill text and available context, the measure appears to be framed as a pro-investment, pro-energy-efficiency tax incentive with no recorded committee debate or votes yet. The structure of the bill suggests support for expanding domestic energy infrastructure and encouraging higher-efficiency cogeneration projects. Because there are no transcripts or vote records provided, there is no documented opposition or formal sentiment beyond the bill’s apparent policy intent.
The main likely points of contention are the scope and eligibility rules for the credit. These include the 20% thermal and 20% electrical output thresholds, the 60% efficiency requirement, the 25 MW/33,500 horsepower capacity cap for full credit treatment, and the exclusion of facilities already receiving the section 45 production credit. Another possible area of debate is the added value for domestic content and energy community projects, which may be viewed as encouraging U.S. manufacturing and redevelopment but could also be seen as narrowing eligibility or increasing compliance complexity. No specific objections or supporters are identified in the available record.
