Basic Service Market Price Adjustment
PLEASE NOTE: If you are on the Fixed Price Option and decide to switch to a competitive supplier in the middle of a pricing period (6 months for residential customers), you will receive a billing adjustment, which will be either a credit or a charge. The billing adjustment compares your Basic Service charges on the Fixed Price Option to what you would have been charged under the Variable Price Option, which is equivalent to the monthly prices National Grid contracts with its Basic Service suppliers. We apply this adjustment to ensure that all Basic Service customers are billed for the actual cost of Basic Service electricity they consume. The calculation uses the monthly rates under the Variable Price Option because they represent our monthly cost of supplying Basic Service to you for the months before you left Basic Service. This Basic Service billing adjustment, referred to as a Market Price Adjustment when it appears on your bill, may be a credit or a charge depending on when you leave Basic Service during the pricing period, and is reflected on your bill prior to when your switch to a competitive supplier is effective. To learn more about this adjustment see
