About Mass Save®
Bringing simple energy savings to Massachusetts
Mass Save is a collaborative of Massachusetts' natural gas and electric utilities and energy efficiency service providers, including Berkshire Gas Company, Blackstone Gas Company, Cape Light Compact, Columbia Gas of Massachusetts, Eversource, Liberty Utilities, National Grid, and Unitil. Our initiative is to help Massachusetts’ residents, businesses, and communities save energy. We empower you to make smart energy choices by offering rebates, financing, and services for energy efficiencies and clean energy improvements.
These programs and services are managed and delivered by electric and gas program administrators, providing the energy expertise to help you save energy and money. The funding is supported from a charge on customers’ energy bills.
Through the joint efforts of the Mass Save collaborative, Massachusetts has earned top ranking as the #1 state in the nation for energy efficiency according to the American Council for an Energy-Efficient Economy (ACEEE).
We continue to make strides in energy efficiency and build a clean energy future for everyone in the state!
