How aggregation works
Municipal electricity aggregation is a form of group electricity purchasing. An electricity aggregation program like Sherborn Power Choice replaces your electricity supplier, and it changes the price that Eversource uses to calculate the supply services charge on your electricity bill. In addition, aggregation can increase the amount of renewable energy in your electricity supply. But electricity aggregation does not replace Eversource as your electric utility.
Here’s how it works:
Without Sherborn Power Choice
(Unless you already have a contract with an electricity supplier)
Typically, Eversource provides two services to you as an electricity customer, and your electricity bill includes charges for both of these services:
|Eversource’s primary role is as an electricity delivery company. They deliver electricity to you, maintain the poles and wires, and address power outages. They charge you for these services on the delivery part of your electricity bill.
|Eversource also provides a second service, which is to be your electricity supplier. They purchase electricity on your behalf and charge you on the supply part of your electricity bill for the amount you use. When Eversource is your electricity supplier, you have Eversource’s Basic Service. This is the default when you open your electricity account.
Eversource’s Basic Service prices change every 6 months for residential and small business customers and every 3 months for large business customers.
With Sherborn Power Choice
In an electricity aggregation like Sherborn Power Choice, Eversource continues to deliver your electricity and you continue to call them when the power goes out, but you no longer have Eversource’s Basic Service for the supply part of your electricity bill. Instead, the Town of Sherborn uses the group purchasing power of the community to secure choose an electricity supplier and to determine the price of the community’s electricity supply and whether any additional renewable electricity is included.
If you participate in Sherborn Power Choice, Eversource uses a Sherborn Power Choice price to calculate the supply portion of your electricity bill instead of their own Basic Service price.
Otherwise, the relationship between Eversource and electricity customers in Sherborn does not change, and your electricity flows without interruption:
