PREDICTION SYSTEM, AGGREGATION SYSTEM, METHOD, AND PROGRAM

A prediction system predicts power demand of each of one or more facilities configured to produce a product. The prediction system includes: a calculation unit configured to calculate, for each of the one or more facilities, a scheduled power usage amount in a target time slot, based on actual result data of consumed power and a production plan of the product; and a determination unit configured to determine, for each of the one or more facilities, a scheduled power purchase amount from a power system in the target time slot, based on the scheduled power usage amount and a power trading price in the target time slot. Thereby, the prediction system can provide information capable of improving a merit for a consumer obtained by cooperating on a request for a demand response.
