ELECTRIC POWER CHARGE CALCULATION METHOD, ELECTRIC POWER CHARGE CALCULATION PROGRAM AND ELECTRIC POWER CHARGE CALCULATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric power charge calculation method with which it is possible to display the lowest price of an electric power charge in the case of a combination of electric power charge plans.;SOLUTION: The electric power charge calculation method includes the processes, executed by a computer, of: calculating a plurality of electric power charges on the basis of a combination of a plurality of charge plan information representing each of electric power charge plans and electric power demand information representing electric power demand; and displaying the lowest price of electric power charge from among a plurality of calculated electric power charges. The electric power charge calculation method, especially, divides electric power demand information into first electric power demand information and second electric power demand information on the basis of minimum electric power used, and successively calculates a total electric power charge consisting of a first electric power charge based on the first charge plan information and the first electric power demand information plus a second electric power charge based on the second charge plan information and the second electric power demand information, respectively for the case where the first charge plan information is contracted under a specific power receive contract and for the case where contract is made under a specific power receive contract with a prescribed amount added or subtracted therefrom.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2018,JPO&INPIT
