Enroll or Change Product

Due to a change in the Eversource billing system you will now need your 11 digit account number and 8 digit service reference number to enroll in the program. You can see a sample bill with the service reference number on the second page here.

Unable to find the service reference number on you bill? You can contact the supplier, Dynegy, at (866) 220-5696 for questions about enrollment.

If you are not participating in Stoneham Community Electricity Aggregation (CEA), you can use the secure online form below to enroll in one of Stoneham CEA products. Once service has begun, your choice will be reflected on your following month’s electricity bill for the previous month’s service. Please note that based on your meter read date, it may take up to two billing cycles to complete enrollment.

If you’re already participating in Stoneham CEA, you can use the form below to opt-up to Stoneham Plus, or to change to Stoneham Standard, or Stoneham Basic.

Be sure to use the name and address associated with the account. Thank you for participating in Stoneham CEA!
