<P>PROBLEM TO BE SOLVED: To improve efficiency of works and procedures concerning a payment of electric power charge by eliminating waste of works on the payment of electric power charge. <P>SOLUTION: An electric power charge billing support device performs the following processes. Information on a measured-value of a power meter at a prescribed period and information on a measured-value of a selling power meter at the prescribed period are obtained. A supplied electric power charge at the prescribed period is calculated based on the obtained information on the measured-value of the power meter, and an excess electric power charge at the prescribed period is calculated based on the obtained information on the measured-value of the selling power meter. Based on the calculated results, when the excess electric power charge is higher than the supplied electric power charge, a subtracted electric power charge is calculated by subtracting the supplied electric power charge from the excess electric power charge, and information on the calculated subtracted electric power charge is output. <P>COPYRIGHT: (C)2012,JPO&INPIT |
