1. An electric power supply system comprising:

  • an electric power accumulating device configured to be charged with electric power, which is supplied from an electric power system into a building under a contract, and configured to discharge electric power to a load device of the building;

    a control device configured tostore an electric power consumption result of the load device,rewrite a previous electric power consumption result to update the electric power consumption result as learning information, andcontrol electric power discharge from the electric power accumulating device to the load device with reference to the learning information, whereinthe control unit is further configured topredict, with reference to the learning information, an electric power consumption consumed by the load device in each time zone in one day,determine, according to the predicted electric power consumption in each time zone in one day, a discharge implementation time zone or a discharge threshold, andimplement electric power discharge from the electric power accumulating device to the load device,when determining that present time is in the discharge implementation time zone in one day, orwhen a load electric power consumed by the load device is greater than or equal to the determined discharge threshold.
