Enrollment Form

IMPORTANT: As of September 7, enrolling and changing from one option to another are temporarily not possible. Chelmsford Choice is preparing to change to a new electricity supplier in November. As a result, Chelmsford’s current electricity supplier, Constellation, is no longer accepting customer requests.

All enrollment and change requests received after September 7 will be placed on a waiting list and implemented after November 1, under Chelmsford’s new program pricing with Dynegy.

Please complete the form below to submit your enrollment request online. Enrollment requests are typically processed within two billing cycles.

Please include the information requested as it appears on your electric utility bill. Be sure to use the name on the account and the account service address when completing the form.

Important note: This form may be used only by residential and small commercial customers that have not previously opted-out of the program. All other customers should contact customer support for information about how to join the program.
