Example National Grid bill

Your National electricity bill is calculated by adding two charges together:

  • Delivery services charges – The cost to deliver electricity to you, maintain the poles and wires, and address power outages.
  • Supply services charges – The cost of the electricity you use.

Delivery services:

The list of delivery services charges appears on the first page of your bill a the first set of charges you see. Delivery services charges are not impacted by your participation in Westborough Power Choice. These charges are regulated.

Delivery charges are the cost to deliver electricity and maintain the delivery infrastructure. Delivery charges are not impacted by Westborough Power Choice.

To find Westborough Power Choice on your bill, move past the delivery services charges and look for supply services charges.

Supply services:

The second part of your bill is supply services. It typically appears on the bottom of the first page or at the top of the second page of your bill. Supply services charges are impacted by your participation in Westborough Power Choice. As a participant in Westborough Power Choice, you will see two changes in the supply services part of your National Grid electricity bill:

  1. Westborough’s electricity supplier, Dynegy, will be listed on your bill as your electricity supplier. Look for the text DYNEGY – WESTBOROUGH POWER CHOICE AGGREGATION. Below that, you will find their contact information:

    PO Box 650764
    Dallas, TX  75265
    WWW.DYNEGY.COM
    866-220-5696

    For help with the program, you may contact Dynegy if you wish, but we recommend first contacting customer support with Westborough’s program consultants.

  2. National Grid will use a Westborough Power Choice price to calculate the supply services charges on your electricity bill instead of their own Basic Service price.
    • To find your supply price, look below the supplier information and find the row labeled Electricity supply. Look to the right to the math problem in parentheses. This is the calculation for your electricity supply charges.
    • The first number is your electricity supply price. That price will reflect which program option you are enrolled in. Westborough Power Choice has three options, and each option has a different price. The graphic below shows you the price you will see for each option.
    • The second number is the amount of electricity you used in the previous billing cycle.

Supply charges are for the cost of the electricity you used. Only the supply charge is impacted by Westborough Power Choice The supply price will be 0.10425 for the Standard Plan, 0.12585 for the 100% Green Plan, or 0.09709 for the Basic Plan.
