Title:
SELECTING METHOD OF ELECTRIC POWER COMPANY AND SELECTION SUPPORTING SYSTEM
Document Type and Number:
Japanese Patent JP3373792
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To facilitate the optimum selection of an electric power company by presenting the combination of contract conditions selected at every electric power company in response to the conditions of consumers in the contract conditions containing at least two of contract terms related to a meter rate, contract capacity related to a minimum charge and contract-load interruption related to a discount charge.
SOLUTION: Consumers beforehand prepare power-consumption predetermined data 4 in conformity with rate systems in an input interface 12. An electric-rate charge calculating section 2 reads the power-consumption predetermined data 4, and outputs predicted electric rates 5a-5c corresponding to electric power companies a-c to a display interface 11 according to rate systems 3a-3c. A condition-combination generating section 6 reads the contents of databases 3 when rates differ by commercial conditions, and generates a plurality of combinations of the commercial conditions and registers the combinations on a combination list 10. The electric-rate calculating section 2 calculates electric rates at every combination, and presents the predicted electric rates 5a-5c to the consumers. Accordingly, the commercial conditions are satisfied, and an electric power company, from which a cheapest electric rate is presented, can be selected.
