The Cambridge Community Electricity program is a City electricity aggregation program that supports the development of local renewable energy projects. The program also offers the potential for savings compared with Eversource’s Basic Service price (though savings cannot be guaranteed), and it provides a City-vetted alternative to Eversource’s Basic Service and to other electricity offers in the market place.

Adding clean electricity to the local grid

You may choose between two options in the Cambridge Community Electricity Program, and through both you will help to add clean electricity to the New England electricity grid:

Participants in both Standard Green and 100% Green Plus will support the development of a new solar energy project in Cambridge through a small $0.002/kWh charge. Once this new solar energy project is up and running, all participants will receive renewable electricity from this project. As a result, all program participants will receive additional renewable electricity above the minimum amount required by the state of Massachusetts and will help to displace fossil fuel-based power production

Choose 100% Green Plus online or call our City consultants at 1-844-379-9934.

All new electricity accounts in Cambridge will be automatically enrolled in the Cambridge Community Electricity program, unless they choose to opt out. If you are not enrolled and wish to participate, you may enroll online or with a phone call. Learn more.

How it works

A municipal electricity aggregation is a group electricity purchasing program. Participating in the Cambridge Community Electricity Program will change your electricity supplier and the price Eversource uses to calculate the Supply charge portion of your electricity bill, but participating will not replace Eversource as your electric utility.

Program savings history

Download a chart showing a historical comparison of the program price with Eversource’s Basic Service price for an average residential electricity customer in Cambridge.

Please note there is no guarantee of future savings. Eversource’s prices change every 6 months for residential & small business customers and every 3 months for large business customers, and future Eversource prices are unknown.


Understand your bill

The Cambridge Community Electricity program makes only minor changes to the way your electricity bill looks. But when you know what those changes are, you can use your bill to confirm whether you are enrolled and which program option you are enrolled in. Learn how to find the program information on your Eversource bill.

Protect your Eversource account number

Eversource will never knock on your door or call you to talk about your electricity bill.
Only provide your Eversource account number if you are ready to change your electricity supplier.

Please note: Cambridge Community Electricity program volunteers may ask if you are interested in switching to the 100% Green Plus option. They will be clearly identified as City volunteers. City volunteers will have you enter your account information directly onto the program’s web form or provide it directly to the supplier via phone.
