A demand control systemaccording to the present invention includes a CPUand a power database. The power databasestores actual data in a state where the actual data are classified according to environmental conditions, the actual data being based on a consumption integration value of power actually consumed by the power consuming device. The CPUcalculates a predicted integration value of power predicted to be consumed in the demand time period, by using contents stored in the power databaseat a start or before the start of the current demand time period. Further, the CPUlowers a power target value when the calculated predicted integration value falls below the power target value being a target value of the power to be consumed in the demand time period.
