PROBLEM TO BE SOLVED: To prevent maximum demand power from increasing caused by an error of a prediction value of a power consumption amount.SOLUTION: A hot water supply control system (40) includes: a prediction unit (52) for calculating a power consumption amount of electric appliances (65a, 65b,...) other than heat pump hot water supply devices (60a, 60b,...) in an object area (15) as a prediction value; a correction unit (58) for calculating an index indicating an error of the prediction value in the past calculated by the prediction unit (52), and correcting the prediction value calculated by the prediction unit (52) on the basis of the index; and a determination unit (54) for determining the number of units of heat pump hot water supply devices (60a, 60b,...) which perform a boiling operation out of the plurality of the heat pump hot water supply devices (60a, 60b,...) in the object area (15), on the basis of the difference between a predetermined reference power amount and the prediction value after the correction by the correction unit (58). |
