The present invention provides a technique to control a distribution of electric power depending on electric power consumption of each of a plurality of electric power receiving apparatuses. An electric power supply apparatus includes an acquisition unit configured to acquire information associated with electric power consumption of each of the plurality of electric power receiving apparatuses, a determination unit configured to determine the distribution of electric power to the plurality of electric power receiving apparatuses based on the information acquired by the acquisition unit such that a greater amount of distribution of electric power is assigned to an electric power receiving apparatus having greater electric power consumption, and an electric power supply unit configured to supply electric power to each of the plurality of electric power receiving apparatuses according to the distribution of electric power determined by the determination unit.
