A management system for managing measurement information on power consumption in at least one electrical appliance which is associated with at least one meter includes a first storage module configured to store measurement information transmitted from each of the at least one meter associated with the at least one electrical appliance, on power consumption in the at least one electrical appliance, in correspondence with the at least one meter. The management system also includes a second storage module configured to store history information on association between each of the at least one meter and the at least one electrical appliance. An information output module may be configured to output, in response to selection of an electrical appliance, as electric power information on the selected electrical appliance, information on power consumption in the selected electrical appliance brought in correspondence with a time period regardless of a meter associated with the selected electrical appliance, which is based on the measurement information in the first storage module and the history information in the second storage module.
