Sutton Power Choice Program

Welcome to Sutton Power Choice, the Town of Sutton’s municipal electricity aggregation program.

Electricity aggregation is a form of group purchasing in which a city or town selects an electricity supplier on behalf of its residents and businesses and secures the price that National Grid uses to calculate the supply services portion of your electricity bill. Sutton developed the program as a way to important benefits to the community:

Price stability

Sutton Power Choice prices are fixed until January 2021, which means the price National Grid uses to calculate the supplier services part of your electricity bill will not change before your January 2021 meter read. Price stability makes the program different from National Grid’s Basic Service price, which changes every 6 months for residential and commercial accounts and every 3 months for industrial accounts.

Potential savings

The Sutton Power Choice program price has the potential to be lower than the average of National Grid’s changing Basic Service prices. However, the program price is a fixed, long-term price, while National Grid’s Basic Service prices change  Because future National Grid prices are not known, the program cannot guarantee to provide savings compared with National Grid.


The program offers two alternatives to National Grid Basic Service: Power Choice Standard, and, for those who wish to make a more significant commitment to renewable energy, Power Choice Green, which supplies you with 100% green electricity. Learn more about the pricing and energy mix for each option.

Program options

Sutton Power Choice offers two options that give you greater control over the price and environmental characteristics of your electricity supply:

All program participants are automatically enrolled in Power Choice Standard. Like National Grid’s Basic Service, Power Choice Standard meets the minimum Massachusetts requirements for integrating renewable energy.

Power Choice Green is an option that allows you to make your electricity 100% renewable with a focus on locally produced renewable energy. Power Choice Green includes 20% from new renewable energy projects in New England, in addition to the minimum amount of renewable energy required by Massachusetts law.

Participate in Sutton Power Choice

New electricity customers in Sutton will be automatically enrolled after receiving a notification letter in the mail. Automatic enrollment is the state law. If you sign a contract with an electricity supplier immediately after opening your electricity account, you will not be automatically enrolled, but you may join. Contact customer support for more information about enrolling.

NOTE: If you receive mail about an electricity offer, but you do not see the Sutton Power Choice logo, the Town seal, and the Town Manager’s name, the mail is NOT from the Sutton Power Choice.

If you participate…

  • National Grid will remain your electric utility:
    • Your bill will continue to come from National Grid.
    • You will continue to send electricity bill payments to National Grid.
    • You will continue to call National Grid if your power goes out.
    • If you are on a budget plan or are eligible for a low-income rate or fuel assistance, you continue to receive those benefits as a participant in Sutton Power Choice.

You will see just two changes on your National Grid bill:

  • Constellation will be listed on your National Grid bill as your electricity supplier (previously it was Agera Energy)
  • National Grid will use the Sutton Power Choice price to calculate the supply services portion of your electricity bill instead of their own Basic Service price. (National Grid’s delivery charges will be unaffected by Sutton Power Choice.)

If you choose to participate, you retain the right to opt out, or leave the program at any time with no fee or penalty.

If you do not participate (if you opt out)…

National Grid will use their own Basic Service price to calculate the supplier services portion of your electricity bill.
