Abstract
A power feeding system includes a power feeding apparatus and a power line communication unit. The power feeding apparatus feeds power from a power line to an external apparatus. The power line communication unit communicates via the power line, which is a communication medium. The power feeding apparatus includes an acquisition unit, a restriction unit and a determination unit. The acquisition unit acquires restriction information used to restrict the feeding of the power to the external apparatus. The restriction unit restricts the feeding of the power to the external apparatus to which the power feeding apparatus is to feed the power. The determination unit determines as to whether or not the restriction unit has to restrict the feeding of the power, based on the restriction information acquired by the acquisition unit.
