Abstract: A VGI system is a system in which electric power is exchanged between a power grid of an electric power utility company and a BEV, and includes a plurality of BEVs, EVSE, and a management server that manages exchange of electric power. The EVSE includes specific EVSE available to a specific vehicle among BEVs, the specific vehicle being permanently permitted to use the EVSE. The management server performs processing for temporarily permitting use of the specific EVSE by a non-specific vehicle different from the specific vehicle on condition that the non-specific vehicle uses the specific EVSE to exchange electric power with the electric power utility company and performs processing for granting an incentive to a user of the non-specific vehicle or a manager of the specific EVSE on condition that the non-specific vehicle has exchanged electric power with the electric power utility company.

Abstract: The server (power management device) is a power management device that acquires information on a power state of an accommodation facility. The server includes a communication unit (acquiring unit) for acquiring the information, and a processor (control unit) for requesting a user of the electrified vehicle to perform power control on EVSE using the electrified vehicle based on the information acquired by the communication unit. Then, when a predetermined condition related to power control is satisfied by the user, the processor gives a privilege related to the accommodation facility to the user.
