Example National Grid bill

Nantucket PowerChoice is integrated into your existing National Grid electricity bill. You can use your National Grid bill to learn if you are enrolled in the program and in which option you are enrolled. See an example National Grid bill.

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 National Grid uses to calculate the supply services charge piece of your electricity bill. In addition, aggregation can increase the amount of renewable energy in your electricity supply. But electricity aggregation does not replace National Grid as your electric utility.
