<P>PROBLEM TO BE SOLVED: To provide a power demand prediction system capable of improving the prediction accuracy. <P>SOLUTION: Respective customers 7a to 7n are notified of predicted individual power usage of every predetermined time of a particular day. An enterprise-side processor 2 compares the estimated individual power usage with actual individual power usage, and discounts power charge when the estimated individual power usage is approximately the same as an actual one. This enables power prediction processing portions 19a to 19n to utilize high-reliability prediction methods for power usage unique to the respective customers 7a to 7n. Furthermore, PPS enterprise 1 can calculate the predicted total power usage by using high reliability predicted individual power usage, and can bring a reservation to a power producer 3 close to the actual power usage of the respective customers. Thus, efficient power supply and demand control can be attained. <P>COPYRIGHT: (C)2007,JPO&INPIT |
