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.

On December 17, 2025, Rep. Van Duyne (R-TX) introduced HR6824, which adds new Section 48F to the Internal Revenue Code to provide a 10% tax credit for qualified combined heat and power system property placed in service. The bill does not authorize or appropriate any federal spending — it operates as a tax expenditure, reducing Treasury revenue by an amount equal to 10% of eligible CHP capital deployment. A companion bill (S3531) has been introduced in the Senate and referred to Finance, increasing the likelihood of bicameral legislative activity.

The money trail is direct: the credit reduces the after-tax cost of CHP equipment, effectively functioning as a per-project subsidy that improves IRR by roughly 1-3 percentage points depending on system size and financing structure. Unlike authorization bills that require future appropriation, this credit is self-executing once enacted — eligible projects placed in service after the effective date automatically reduce tax liability.

Structural winners are equipment OEMs: Cummins ($CMI) with its reciprocating engine CHP products, GE Vernova ($GEV) with aeroderivative and heavy-duty gas turbines, and Caterpillar ($CAT) with Solar gas turbines and Cat reciprocating engines. NextEra ($NEE) is a secondary beneficiary as a developer of distributed generation, but CHP is a small fraction of its Energy Resources segment compared to wind and solar. The credit specifically excludes property that is part of a facility claiming the Section 45 production tax credit for renewables, so no cross-market conflict arises with solar/wind.

Market data as of April 30, 2026 shows $CMI at $665.01 (30-day +23.6%), $CAT at $879.21 (30-day +24.1%), $NEE at $96.56 (30-day +3.96%), and $GE at $289.66 (30-day +2.08%). The 30-day CHP-equipment-adjacent rally is notable: $CMI and $CAT are respectively within 0.6% and 1.2% of their 52-week highs, suggesting market participants are pricing in improved industrial capital spending broadly, potentially including anticipation of CHP tax incentives. $GE (Aerospace) has not benefited in the same way, confirming that $GEV (GE Vernova) should be treated as the pure-play beneficiary, not the $GE parent.

Legislative timeline: HR6824 is early-stage with only one committee referral (Ways and Means) and one cosponsor. Passage requires committee markup, House floor vote, Senate committee action on S3531, Senate floor vote, and presidential signature — a multi-year path. The bill has not yet advanced past referral status. Given the partisan composition of the 119th Congress (Republican-controlled House and Senate), the bill has a moderate probability of inclusion in a year-end tax extenders package or energy-permitting reform vehicle, but standalone passage before 2027 is uncertain.
