A spare power acquirer (121b) is configured to, each time a set time period shorter than a specified time period elapses, obtain an average power consumptions of an electrical apparatus (11) in the set time period, and obtain a spare power of the average power consumption with respect to a target power in the set time period based on the set power. Also, an updater (121c) is configured to, when the spare power obtained by the spare power acquirer (121b) is a positive value, update the target power in a next set time period to a power obtained by adding the spare power to the set power, and when the spare power obtained by the spare power acquirer (121b) is a negative value, update the target power in the next set time period to a power obtained by subtracting an absolute value of the spare power from the set power, and then report the updated target power to a controller (111) that controls an air conditioner (11). |
