About Mass Save®

Bringing simple energy savings to Massachusetts

Together, we make good happen for Massachusetts.

Your local electric and natural gas utilities and energy efficiency service provider are taking strides in
energy efficiency: Berkshire Gas, Blackstone Gas Company, 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.

Through the joint efforts of the Mass Save collaborative, Massachusetts is one of the most energy efficient states in the country, 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!
