The ground-side communication device communicates directly or indirectly with the moving body. The power transmission control device is configured to: count the number of times a power transfer abnormality has occurred between the power transmission device and the power reception device or the number of times an abnormality occurrence notification that is sent from the moving body when the power transfer abnormality is detected in the moving body; and determine that there is an abnormality in the power transmission device when the number of times the power transfer abnormality has occurred or the number of times the abnormality occurrence notification has been received becomes equal to or greater than a predetermined value.
