In this power control system (1), a server (100) transmits, to each facility, an upper-limit set value for power capable of being supplied to each facility, and data (162) predicting the change over time in the power consumption of each facility having power supplied thereto. A HEMS controller (700) calculates, on the basis of prediction data (741), the total amount of consumed power exceeding an upper-limit set value (742), in time zones in which power supplied to the facility from the grid exceeds the upper-limit set value. A power conditioner (820) ensures in advance that power corresponding to the calculation result will be in an electrical storage battery (830), and stores electricity in the electrical storage battery (830) in an amount corresponding to the ensured electrical storage capacity. In cases when the power consumption of the facility exceeds the upper-limit set value, the power conditioner (820) supplies, to the facility, power from the electrical storage capacity ensured in the electrical storage battery (830), such that the upper limit of the power supplied from the grid to the facility does not exceed the upper-limit set value. |
