How aggregation works
Municipal electricity aggregation is a form of group electricity purchasing. Electricity aggregation replaces your electricity supplier, and it changes the price that Eversource uses to calculate the Supply charges on your electric 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 Walpole Power Choice
(Unless you have a contract with an electricity supplier)
Typically, Eversource provides two services to you as an electricity customer, and your electric bill includes charges for both of these services:
|Eversource’s primary role is to deliver your electricity. Their responsibilities also include maintaining the delivery infrastructure (the poles and wires) and addressing power outages. They charge you for these services in the Delivery portion of your electric bill.|
|Eversource can also provide a second service, which is to supply your electricity. This means they purchase electricity on your behalf and charge you for the amount you use in the Supply portion of your electric bill. When Eversource supplies your electricity, their Basic Service price is used to calculate the Supply portion of your bill. Basic Service prices change seasonally. When you first open your electricity account, you are placed on Eversource’s Basic Service.|
The diagram below shows Eversource both delivering and supplying electricity.
With Walpole Power Choice
In an electricity aggregation like Walpole Power Choice, you remain an Eversource customer. They continue to deliver your electricity, and you continue to call them when the power goes out. They also continue to send your electric bill, and you continue to send bill payments to them.
However, Eversource no longer supplies (buys) your electricity. As a result, you no longer have Eversource’s Basic Service price for the Supply portion of your electric bill.
Instead, the Town of Walpole uses the group buying power of the community to sign a contract with an electricity supplier and establish an electricity Supply price for the community. Eversource then uses a Walpole price instead of their own Basic Service price to calculate the Supply portion of your bill. Walpole’s prices are typically fixed, long-term prices that do not change seasonally.
Through the program, the Town can also choose to buy more electricity from renewable sources than is required by state law. For participants in the Power Choice Green option, Walpole buys more electricity from renewable sources than is required by state law.
