Abstract: A power distribution system includes: a remote electricity monitoring device which is provided at each power supply destination, and remotely reads, via communication means, an consumed power amount and an surplus power amount stored in a power storage device at each supply destination; and a management server which manages the power supply of each supply destination while collecting, via the communication means, the consumed power information and the surplus power information, both of which are read by the remote electricity monitoring device. The management server distributes the power among the supply destinations in line with the relationship between the power amounts based on the consumed power information and surplus power information.

Abstract: An electric power supply system includes: a distributed power supply which is disposed in at least one of a first power consumer; a power line which supplies the surplus power generated in the distributed power supply to at least one of a second power consumer; and a management device which manages the trade price of the surplus power supplied via the power line. The management device determines the trade price of the surplus power for following days on the basis of a prediction value for the amount of surplus power in the first electric power consumer unit and a prediction value for the amount of electric power consumption in the second electric power consumer unit over the following days.
