Opt Out

You may choose not to participate in the program. This is called opting out. There is no penalty for opting out, and you may opt out at any time. If you choose to opt out, you will be switched back to Eversource’s Basic Service for your electricity supply.

If you opt out and then wish to opt back into the program, you are not guaranteed the program price. The electricity supplier is entitled to charge you a market price for the remainder of the current electricity supply contract, but you would receive the Cambridge Community Electricity Program price for any future electricity supply contracts. If the program’s electricity supplier decides to charge market pricing, you will be notified before enrollment and can decide then whether to continue with enrollment or not.

You may opt out online using the form below.

Be sure to use the name on the account and the account service address when completing the form.
