To control power supply from a storage battery so as to surely obtain economic profit.
A control device for making it possible to perform charge/discharge control so as to surely obtain economic profit comprises: a charge control unit for charging a storage battery with power acquired from a system; and discharge control unit which makes the storage battery discharge charged power when a substantial cost of supply power calculated on the basis of a first acquisition cost required for acquiring the charged power charged in the storage battery and conversion efficiency in obtaining the supply power for supplying the charged power converted from direct current to alternating current by a converter to a power load is equal to or smaller than a second acquisition cost required for acquiring the supply power from the system, and prohibits the storage battery from discharging the charged power when the substantial cost is larger than the second acquisition cost.
