Your total bill is divided into two services, Delivery and Supply.

Delivery is the process of bringing electricity to your home or business. National Grid is responsible for the delivery of electricity, reading your meter, repairing the poles and wires, and restoring power.  The delivery services cost is based on the number of kWh used multiplied by National Grid’s Delivery rate. The aggregation does not affect these services.

Supply refers to the electricity itself. The supply services cost is also based on the number of kWh used multiplied by a supply rate. If you do not choose your own competitive supplier or are not part of an aggregation, National Grid is required to choose a supplier for you and charges you at their supply rate, which is called Basic Service.

You have been and will always be charged for both Supply and Delivery regardless of whether you are in an aggregation, choose your own competitive supplier or remain on Basic Service. However the look of your monthly bill will change. Before enrollment in the aggregation, the charges in the Account Balance section are combined into one Amount Due column (Delivery + Supply). After enrollment in the aggregation, the charges in the Account Balance section are broken into three columns: National Grid Services (Delivery), Other Supplier Services (Supply) and Total (Delivery + Supply).  Also, under the Detail of Current Charges section of your bill, the supplier chosen by your community will be listed in the Supply Services section.
