1. A power storage control system comprising:
a monitor configured to monitor a predetermined index value having a correlation with a deterioration extent of a storage battery, for each storage battery included in a plurality of power storage systems; and
a charge/discharge controller configured to control a period in which the predetermined index value changes to a predetermined value of each of the storage batteries due to deterioration accompanying charging and discharging of the storage batteries, by performing control related to at least either of decreasing an upper limit for charge amount of the storage battery, or raising a lower limit for the charge amount of the storage battery, based on monitoring results of the monitoring.
