[Problem] To provide a power supply system which effectively utilizes a power storage unit and also limits degradation of the power storage unit. [Solution] A power supply system () is provided with: a power storage unit () for charging supplied electric power and supplying the charged electric power by means of discharge; and a power storage unit controller () for controlling the discharging of the power storage unit (). The power storage unit controller () sets a discharge period during which the power storage unit () can be discharged. Furthermore, during the discharge period, the power storage unit controller () determines the electric energy to be supplied by means of the discharging of the power storage unit () during the remaining discharge period on the basis of the remaining discharge period and the electric energy that can be discharged by the power storage unit ().

Power supply system

[Objective] To provide a power supplying system wherein the timing at which a storage unit conducts capacity learning is made to be more suitable. [Solution] A power supplying system supplies power to loads provided within a facility, and is provided with: a power storage unit that stores power by being charged, and supplies power by being discharged; and a capacity measurement unit that measures the remaining capacity of the power storage unit by executing a complete charging and a complete discharging of the power storage unit, in sequence. The capacity measurement unit obtains the operation schedule of the facility, and determines the timing at which the complete charging and the complete discharging of the power storage unit are to be conducted, on the basis of the operation schedule.
