Clean Energy & Energy Efficiency

The City of Somerville has several programs aimed at improving access to clean energy and energy efficiency measures in homes and buildings. The majority of Somerville’s greenhouse gas emissions come from our buildings. Therefore, improving access to clean energy and incentivizing energy efficient buildings is a key priority for achieving carbon neutrality. In addition to the climate change benefits, clean energy and energy efficiency can also help to reduce utility costs for residents and help make Somerville’s homes more comfortable.


Community Choice Electricity Program

Somerville Community Choice Electricity is an electricity supply program offered by the City of Somerville to provide residents and businesses with new, City-vetted options for electricity supply. Eversource continues to deliver your electricity, repair power outages, and maintain the electricity grid; they also send you one bill for the electricity you used.

On the Somerville Community Choice Electricity website (, residents, business owners, and other electricity customers can:

  • Learn how the program works;
  • See different electricity products;
  • Easily enroll in any of the program options or leave (opt-out) the program;
  • Read the aggregation plan;
  • See the benefits of supporting renewable energy generation.

Notices About the Program

Please keep in mind that future savings cannot be guaranteed because Eversource Basic Service rates change every six months for residential and commercial customers and every three months for industrial customers.

Newly eligible customers will receive a Customer Notification Letter detailing the program and ways to leave the program (opt out); those who choose not to opt out will be automatically enrolled.

Customers who have chosen a third-party supplier will not receive a Customer Notification Letter and will not be automatically enrolled. They can voluntarily join the program, but they may be subject to penalties or early termination fees from the third-party supplier if they switch to the electricity program during the term of their contract with their chosen supplier.

In October 2015, the Board of Aldermen authorized the creation of a community choice aggregation plan in Somerville. After accepting public comments, receiving approval by the Board of Aldermen, and undergoing review by the Department of Energy Resources, the City of Somerville received approval for its plan from the State's Department of Public Utilities in April 2017. You can download a copy of the plan here. As with all municipal aggregation programs in Massachusetts, Somerville Community Choice Electricity employed a competitive procurement process designed to maximize savings and provide a full set of consumer protections, including the right for any customer to opt out of the program at any time at no charge.

Somerville Energy Efficiency Now! (SEEN)

SEEN is a program through the Office of Strategic Planning and Community Development Housing Division that works to make Somerville’s housing more energy efficient by encouraging residents to take advantage of existing offers and programs through MassSave. MassSave provides no-cost Home Energy Assessments to Somerville homeowners, landlords, and tenants. An energy assessment takes between one and three hours and will help identify energy and cost saving improvements in your home. If 1,001 Somerville residents complete Home Energy Assessments in 2017, the City of Somerville will earn $40,000 for future energy efficiency initiatives from National Grid!


Sign up for your Mass Save no-cost Home Energy Assessment today and learn more about additional incentives here.

Solar Energy

The City of Somerville has made it a priority to help reduce costs and barriers for residents looking to go solar. If you are interested in learning more about going solar, please visit the Somerville Energy Efficiency Now page.

In 2016, the City of Somerville ran the highly successful Solarize Somerville campaign to spur residential solar installation. A total of 115 households signed up to make the switch to solar through this program—increasing Somerville’s installed solar capacity by over 500 kW.  The Solarize program may have ended, but you can still get solar for your home. If you are interested in solar, you can get started by reviewing the information on the Renewable Energy tab of the Somerville Energy Efficiency Now site.

SolSmart Gold Award: Nationally Distinguished, Locally Powered

For our efforts to make it faster, easier and cheaper to go solar, Somerville has earned SolSmart Gold Designation from SolSmart, a national designation and technical assistance program funded by the U.S. Department of Energy SunShot Initiative. SolSmart nationally recognizes communities for adopting programs and practices that make it faster, easier, and cheaper to go solar. A SolSmart designation is a signal that the community is “open for solar business,” helping to attract solar industry investment and generate economic development and local jobs. Earlier this year, Somerville became the first community in the Commonwealth to be designated Bronze. Somerville is now the first community in Massachusetts to earn Gold.


From L to R: Mayor Joseph A. Curtatone, Solar Coach Mary Mangan, Director of Sustainability Oliver Sellers-Garcia, Housing and Environment Programs Coordinator Christine Andrews, and Housing and Environment Programs Manager Russell Koty pose with the cleverly designed SolSmart Bronze Designation Award.
