Few. Duke Energy Ohio's current efficiency funding covers only income-eligible customers, and CenterPoint Energy's Ohio gas system serves the Dayton region, not Hamilton County. Northern Kentucky homes on Duke Energy Kentucky can get up to $250 through Smart $aver when a participating trade ally does the work.
More detail
Start with who actually sends your bills. In Hamilton County and most of the Ohio side of the metro, Duke Energy Ohio (the old Cincinnati Gas and Electric) supplies both electricity and natural gas, and its residential efficiency rebates wound down after Ohio's 2019 House Bill 6 ended the state's utility efficiency mandate. The rate plan the PUCO approved in May 2025 funds a $7.2 million efficiency program over three years for income-eligible customers only, so a market-rate household should not expect a Duke Energy Ohio insulation rebate in 2026. CenterPoint Energy's Ohio gas business is the former Dayton Power and Light gas system in western Ohio, so its programs rarely touch a Cincinnati address. Across the river, Duke Energy Kentucky still files a Residential Smart $aver program with the Kentucky Public Service Commission; the tariff caps the incentive for thermal envelope improvements at $250, requires a Duke Energy Kentucky participating trade ally to do the work, and leaves the posted amounts to the utility's website, so check the current form before the job is scheduled. Duke Energy Kentucky also runs income-qualified programs that can include attic insulation and blower-door air sealing. On either side of the river, households at or below 200 percent of the federal poverty guidelines, or receiving SSI, can apply for the Weatherization Assistance Program through the state's local agencies. The federal Section 25C credit is gone for anything placed in service after December 31, 2025. That leaves the project to stand on its own savings, which is why the rim joist and attic air sealing, the cheapest high-return pieces, usually come first.
