SERVER AND POWER MANAGEMENT METHOD

A server that manages a plurality of power adjustment resources electrically connectable to a power network includes a determination unit and a first permission unit. The determination unit determines, before a vehicle including a power storage starts charging of the power storage by using the power network, whether or not electric power corresponding to charging power can be supplied to the power network by having at least one of the power adjustment resources respond to the charging of the power storage. When the determination unit determines that electric power can be supplied, the first permission unit permits supply of electric power from the power network to the vehicle.
