The present invention addresses the problem of more flexibly controlling a storage battery. This storage battery control device 1 comprises a control unit 10 which, after one or a plurality of storage batteries 3 are determined as charge/discharge control targets for responding to a demand response (DR) request, when detected that charge/discharge criteria for responding to the DR request cannot be satisfied, performs at least either a first control utilizing the storage batteries 3 not being controlled or a second control utilizing the storage batteries 3 having remaining charge/discharge power after responding to the DR request from among the storage batteries 3 being controlled. The second control may utilize the storage batteries 3, which have remaining charge/discharge power after responding to the DR request from among the storage batteries 3 being controlled, in a period during which the storage batteries 3 are not to be utilized within the period for responding to the DR request. The control unit 10 may perform the second control in priority to the first control. The control unit 10 may determine whether the criteria is satisfied by the second control or not and then perform control based on the determination result.
