Summary

What This Bill Does

This bill creates a new federal tax credit for businesses that install combined heat and power (CHP) systems—technology that simultaneously generates electricity and useful thermal energy from a single fuel source. The credit equals 10% of the cost of qualifying CHP property, with potential bonuses of 10 additional percentage points each for using domestically manufactured components and for locating in energy communities (areas affected by fossil fuel industry closures).

Who Benefits and How

Businesses and industrial facilities that install CHP systems benefit from significant tax savings, reducing the cost of energy efficiency investments. Manufacturers of CHP equipment benefit from increased demand. Energy communities and areas with domestic manufacturing capacity receive additional investment incentives. Facilities using biomass fuels qualify under relaxed efficiency rules, benefiting the biomass energy sector.

Who Bears the Burden and How

The federal government bears the cost through reduced tax revenue from the credits claimed. All taxpayers indirectly bear this cost through either higher taxes elsewhere or increased federal deficits. The Secretary of the Treasury and Secretary of Energy bear administrative burdens for establishing performance standards and issuing implementing regulations.

Key Provisions

  • Creates new Section 48F in the Internal Revenue Code with a base 10% investment tax credit for CHP systems
  • Adds 10 percentage point bonus for projects meeting domestic content requirements
  • Adds 10 percentage point bonus for projects in energy communities
  • CHP systems must produce at least 20% thermal and 20% electrical energy, exceed 60% efficiency, and begin construction after December 31, 2024
  • Caps eligible system size at 50 megawatts (67,000 horsepower) with pro-rata reduction above 25 megawatts
  • Provides special rules for biomass-fueled systems with relaxed efficiency requirements
