Key Points

  • Congress would create a tax credit equal to 10% of the cost of certain combined heat and power systems put into service.
  • The credit could be larger (an extra 10 percentage points) if the project meets “domestic content” rules or is located in an “energy community.”
  • To qualify, the system must meet efficiency and output rules (it must produce both useful heat and useful power) and construction must begin on or after January 1, 2025.
  • Very large systems would face limits: credit phases down above 25 megawatts and systems above 50 megawatts would not qualify.
  • This mainly affects businesses, factories, hospitals, and campuses that might install these systems; it could lower their tax bills and encourage on-site energy upgrades.

2025-01-01

New CHP tax credit becomes available for projects that start construction after Dec. 31, 2024

If a business begins building a qualifying CHP system after that date, it can plan to claim a credit when the system is finished and placed in service, lowering its federal tax bill.

After the bill becomes law (timing not specified in the text)

Treasury/IRS issues guidance on performance standards, records, and reporting

Project owners will need clear rules on what qualifies (efficiency testing, documentation, domestic content proof) before claiming the credit with confidence.

Starting with the first tax year after enactment when qualifying systems are placed in service

Businesses begin claiming the credit for CHP systems they place in service

Eligible companies can reduce their taxes for the year their CHP system starts operating; this can improve cash flow and shorten payback time on the project.
