Eversource Energy’s flagship Residential Energy Efficiency program is set to play an even bigger role in 2026, as the New England utility updates rebates for heat pumps, weatherization and smart thermostats to blunt the impact of higher energy bills for households in its service territory. According to Eversource, qualifying customers can now access incentives that in many cases cover most or even all of the upfront cost of key efficiency upgrades when combined with federal tax credits and other support on its official program page.

What Eversource’s Residential Energy Efficiency program offers in 2026

The Residential Energy Efficiency program groups a set of offerings that Eversource and its fellow Mass Save sponsors describe as a core pathway to cutting energy use and emissions in Massachusetts homes, from no-cost energy assessments to rebates on high-efficiency equipment and building shell upgrades. In its latest guidance for 2026, Eversource highlights incentives for electric air-source heat pumps, ground-source heat pumps, heat pump water heaters, insulation, air sealing and Wi-Fi thermostats, with typical rebates for qualifying central air-source heat pump systems in cold-climate configurations reaching several thousand dollars per home, depending on capacity and efficiency levels as defined in the Mass Save technical requirements in current Mass Save documentation.

In parallel, the program continues to emphasize whole-home energy assessments, usually delivered at no cost to eligible customers, which identify insulation gaps, air leaks and inefficient equipment and generate customized proposals for upgrades tied directly to available rebates and on-bill repayment options. Eversource points out that income-eligible households may qualify for enhanced incentives that substantially reduce or eliminate out-of-pocket costs for insulation and weatherization, as part of the broader Mass Save framework approved by Massachusetts regulators for the 2025 to 2027 three-year energy efficiency plan, which targets substantial cumulative energy savings and greenhouse gas reductions across the residential sector.

Beyond major equipment, the Residential Energy Efficiency program also covers smaller but still meaningful measures such as advanced power strips, efficient lighting in certain contexts and incentives for integrated controls that allow customers to manage heat pumps and backup systems more intelligently. While earlier program phases focused heavily on lighting, Eversource is now steering customers toward deeper, structural upgrades like building envelope improvements and electrification-ready measures, aligning with state decarbonization goals and the utility’s own net-zero by 2030 operations target. For many homeowners, the path starts with booking an assessment through the utility and then layering available rebates, low-interest financing and, where applicable, federal incentives from the Inflation Reduction Act on top of each other.

To broaden participation among small businesses and mixed-use properties that often share characteristics with larger homes or multiunit buildings, Eversource and its fellow sponsors launched the 2026 Main Streets initiative under the Mass Save umbrella, offering no-cost energy assessments and direct-install measures such as LED lighting and programmable thermostats in selected commercial corridors, while also pointing participants toward deeper retrofit options that mirror the residential offerings in structure and incentive design as outlined in a June 2026 Mass Save announcement.

Within Eversource’s portfolio, the Residential Energy Efficiency program is a strategic lever to manage load growth, defer certain distribution upgrades and support state policy targets, while also reinforcing the company’s public commitment to carbon-neutral operations by 2030 across its electric, gas and water businesses. The utility is investing alongside partners in major transmission and distribution projects such as the Greater Cambridge Energy Project to improve reliability for the Boston area, and residential demand-side measures like heat pump adoption and insulation are intended to complement that grid buildout by moderating peak demand and integrating more renewable generation efficiently. Shares of Eversource Energy (US30040W1080) traded on the New York Stock Exchange at around $58.70 on 06/14/2026.
