Mass Save - Residential Energy Efficiency Programs

April 25, 2024


About Mass Save

Your local electric and natural gas utilities and energy efficiency service provider are taking strides in energy efficiency: Berkshire Gas, Cape Light Compact, Eversource, Liberty Utilities, National Grid and Unitil.

As one, we form Mass Save®, with the common goal of helping residents and businesses across Massachusetts save money and energy, leading our state to a clean and energy-efficient future.

These programs and services are managed and delivered by electric and gas Sponsors (working closely with the Massachusetts Department of Energy Resources), providing the energy expertise to help you save energy and money. The funding is supported from a charge on customers’ energy bills.


Rebate applications are available online for appliance and heating/cooling system rebates. Mass Save offers discounted prices through its online store for shower fixtures, CFL/LED lighting and fixtures, and advanced powerstrips. Lighting discounts can also be obtained in-store at participating retailers.

Mass Save also offers customers an incentive of 75%-100% of the cost of installing approved insulation improvements. Low-income customers and multi-family building owners may be eligible for additional incentives, including a free comprehensive energy assessment. See the program website listed above for details on each of Mass Save's residential energy efficiency rebate offerings.
