Enroll or Change

If you are not participating in Wrentham Community Electricity, you can use the secure online form below, or contact the supplier, Dynegy, at (866) 220-5696 to enroll in any of Wrentham Community Electricity products. Once service has begun on or after July 9, 2025, 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.

Please note: If you are a new medium, large or very large business customer, or if you have previously opted out of the Program, the supplier has the option to offer a market price. Market prices will be offered by the electricity supplier in writing or phone, and you will not be enrolled in that price unless you affirmatively accept.

Be sure to use the name and address associated with the account. Thank you for participating in Wrentham Community Electricity!
