National Grid
Backout Rate (Not applicable after December 31, 2011) The Backout Rate is the annual market price forecast for energy, agreed upon by the parties in National Grid's rate reduction and restructuring plan, which was used to calculate Competitive Transition Charges that are applied by load zone, service class and voltage level. However, actual Electricity Supply Charges for customers that choose our Electricity Supply Service are based on Location Based Marginal Prices posted by the NYISO and in accordance with Tariff Rule 46.
