Abstract. A flywheel energy storage (FES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems that is most appropriate for small- and medium-scale uses and shorter period applications. In an FES system, the surplus electricity is stored in a high rotational velocity disk-shaped flywheel.
