If you are not already participating in the Millbury Power Choice Community Electricity Aggregation program and would like to enroll, please complete the secure online form below. Be sure to use the name and address associated with the account. Your account will be enrolled on the next available meter read. Alternatively, you may contact the program supplier, NextEra Energy Services, directly at (855) 639 – 8195, Monday through Friday, 9:00 AM to 5:00 PM EST (excluding holidays). Please have your National Grid account information available when contacting. 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.
