What is not covered in Connecticut
No open program with a published amount was found for induction range or cooktop, electrical panel upgrade. That does not prove nothing exists: a municipal utility or a pilot can run its own offer, and the methodology page lists the program pages that could not be read. Where the federal credit used to cover one of these, it has ended.
Connecticut HEEHR (formerly HEAR) and HOMES (formerly HER)
Not launched. “Rebates will not be available until the programs are launched.” In June 2026 DEEP reported it was “actively reviewing the new guidance” DOE issued on June 1, 2026; no launch date is given. The state page describes: HEAR requested to target households under 80% AMI; To be administered mostly through the regulated electric utilities.
