For each of the electric apparatuses belonging to an electric apparatus combination that was created by an apparatus calculation unit according to a target power-saving amount, a demand control information creation unit creates demand control information including a predetermined power corresponding to the target power-saving amount and a predetermined time of operating at this power. A demand request creation unit creates a demand request which is a signal which requests operation based on the demand control information for the apparatuses in the combination. When the predetermined time elapses, the apparatus calculation unit selects at least one or more apparatuses other than the apparatuses which are currently selected and additionally creates a new combination that is different from the current combination according to predetermined rules, and a communication unit sends the demand control information to the apparatus selected by the apparatus calculation unit.
