Federal tax incentives for clean energy upgrades are going away at the end of this year, cutting into potential savings on rooftop solar, heat pumps and more. In 2026, homeowners who install a heat pump will no longer be able to apply for federal tax credits amounting to 30 percent off installation costs or new equipment. At the same time, a pilot program from Central Maine Power that charged a lower rate in the winter to certain customers with heat pumps is also set to expire. This means that homeowners may see costs associated with installing and running a heat pump go up next year. Efficiency Maine Trust, the quasi-state agency responsible for energy programs, plans to continue offering several types of heat pump rebates.
