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 marketplace.

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:

Standard Green - 10.20¢/kWh default program offering. 100% Green Plus - 13.669 ¢/kWh 100% renewable option.

Participants in both Standard Green and 100% Green Plus support the development of a new solar energy project in Cambridge through a small $0.002/kWh charge. All program participants 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.

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.

Protect your Eversource account number

Eversource will never knock on your door or call you to talk about your electric 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.
