And the main controller 4 performs the electric power supply restriction notification Y with respect to the customer terminal 52 in the customer 51 in which reception of the supply impossible load was performed (S8). The power supply restriction notification Y indicates which load 54 is the load that can be supplied and the load that cannot be supplied. And in each consumer 51 who owns a supply impossible load, it can recognize that supply of the electric power which makes this supply impossible load move is not performed. Note that the main controller 4 can issue a power supply availability notification X to the customer terminal 52 in the customer 51 that has not received an unsuppliable load.

When the total power consumption prediction amount A exceeds the supply prediction amount B, when the power supply management starts, the sub-controller 53 in each consumer 51 uses the power corresponding to the individual power consumption amount a of the load that can be supplied. Accept to customer 51.
Further, the main controller 4 determines whether the individual power consumption a for each type of the load 54 exceeds a predetermined reference power amount in the information input to the customer terminal 52 of each customer 51 or the individual power consumption a When the total of the power consumption exceeds a predetermined reference power amount, the customer terminal 52 can be notified so that the input is not accepted. The notification in this case can also be the power supply restriction notification Y. The consumer 51 can review each individual power consumption amount a or the total of the individual power consumption amounts a.
The power supplied from the storage battery 31 to the customer assembly 5 is repeatedly controlled and managed every day by the main controller 4.

  In the power supply system 1 of the present example, when the supply of power by the power supply trailer 2 is insufficient while taking into account the demand from the customer 51, the power is supplied to the customer 51 satisfying a predetermined constraint condition. Can be notified that the supply is limited. Therefore, it is possible to more appropriately control and manage the supply of power to the consumer aggregate 5 using the power supply trailer 2.
