A CEMS server includes a control device that executes a notification process of notifying a user of an electrified vehicle of promotion information for promoting charge or discharge, and a storage device that stores a program executable by the control device. The control device executes the notification process in a case where a first condition and a second condition are satisfied. The control device does not execute the notification process in a case where the first condition or the second condition is not satisfied. The first condition is a condition that a destination of the electrified vehicle is a predetermined place at which the charge or discharge of the electrified vehicle is possible. The second condition is a condition that a request for the charge or discharge is estimated in a period in which the electrified vehicle is present at the predetermined place.
