Home Electrification and Appliances Rebate program (section 50122);
State-Based Home Energy Efficiency Contractor Training Grant program (section 50123); and
Assistance for Latest and Zero Building Energy Code Adoption program (section 50131).
CBO assumes that H.R. 4758 will be enacted early in calendar year 2026. The 2025 reconciliation act rescinded unobligated balances for the contractor training program. CBO estimates that about $300 million in unobligated balances will be available for the other two programs at the time of enactment. Accordingly, CBO estimates that enacting the bill would reduce budget authority in 2026 by about $300 million.
However, relative to the January 2025 baseline, CBO does not expect that those balances will be spent under current law. On that basis, CBO estimates that enacting H.R. 4758 would not affect direct spending over the 2026-2035 period.[1]
The CBO staff contact for this estimate is Aaron Krupkin. The estimate was reviewed by H. Samuel Papenfuss, Deputy Director of Budget Analysis.
