Abstract
An information apparatus of a demander is connected via a communication line to an information apparatus of a power company or enterprise. When a power supply contract is signed between the enterprise and the demander, the enterprise presents information of contract (start) periods and information of a unit price of charge for each contract period. According to the information, the demander sets a customized pattern (load pattern) for each desired one of the periods and sends the pattern to the enterprise. The enterprise presents information of charge for the load pattern. The demander determines a power supply contract for the periods. In the operation, the demander collates the load pattern at a present time with a load pattern in a predetermined period in the past and re-sets values of the load pattern at the present time. The enterprise presents information of charge for the load pattern modified and set by the demander.
