GAP DEGREE CALCULATION DEVICE AND GAP DEGREE CALCULATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a mechanism to indicate a gap degree between the benefit that a consumer wishes to be provided with and the amount that the consumer saves.SOLUTION: A gap degree calculation device comprises: a target charge calculation part that calculates, based on a type of the benefit provided for a consumer according to a difference between the use charge of energy supplied to the consumer by an energy supplier and the payment charge which is paid to the energy supplier by the consumer, a target charge which is a target value for the payment charge corresponding to the benefit; an estimate charge calculation part that calculates an estimate charge which is an estimate value for the difference based on use charge information indicating the use charge; a gap degree calculation part that calculates a gap degree between the target charge calculated by the target charge calculation part and the estimate charge calculated by the estimate charge calculation part; and a gap information output part that outputs gap information indicating the gap degree calculated by the gap degree calculation part.SELECTED DRAWING: Figure 1
