Next, in step S28, when the surplus power is supplied to the consumer B30, it is determined whether or not the power storage device 27 still has a power storage amount. Here, if it is determined that there is a stored amount, the process returns to step S26 again to enter the flow of searching for a supply destination. On the other hand, when the surplus power is supplied to the consumer B30 and it is determined that there is no stored electricity, the process proceeds to step S29.
On the other hand, in step S29, since it is determined in step S26 that there is no supply destination of surplus power, the supply destination of surplus power is set to the power storage device 27 owned by the own house (customer A20), and the process ends.

On the other hand, in step S30, since there is no power consumption by the load 24 in the consumer A20, it is determined whether or not there is a power supply amount by the power supply device owned by the consumer A20. Here, if there is a power supply amount, the process proceeds to step S25, and if there is no power supply amount, the process proceeds to step S31.
Next, in step S31, since the consumer A20 is in a situation where the power supply device does not supply night power, it is determined that the consumer A20 does not generate surplus power, and the process ends.
