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.
