  • a unit arranged to store performance data of a power consumption integrated value for each individual environmental condition in a power database;

    a predicted value calculating unit arranged to calculate a predicted value of the power consumption integrated value for each one of a plurality of demand time intervals including a current demand time interval and a predetermined number of demand time intervals subsequent to the current demand time interval based on the performance data stored in the power database at a start of the demand time interval; and

    a control unit arranged to control the appliances based on the predicted value calculated by the predicted value calculating unit for each one of the plurality of demand time intervals and on a pre-set target value, wherein the control unit comprises;

    a unit arranged to change, when the plurality of demand time intervals include the demand time interval in which the predicted value exceeds the target value and the demand time intervals in each of which the predicted value does not exceed the target value, and operation contents each scheduled in the demand time interval in which the predicted value exceeds the target value include the operation content whose operation time is changeable, the changeable operation time of the operation content such that the operation content whose operation time is changeable is executed in any of the demand time intervals in each of which the predicted value does not exceed the target value.
