Your account will be enrolled on the next available meter read.

Please note, in Massachusetts, a minimum of two days prior to the meter reading date for your account is required in order for the electric utility to process an enrollment request. Monthly service cannot be prorated. Once service has begun, the program rate will be reflected on your following month’s electricity bill for the previous month’s service.
