The principle of rotating mass causes energy to store in a flywheel by converting electrical energy into mechanical energy in the form of rotational kinetic energy. 39 The energy fed to an FESS is mostly dragged from an electrical energy source, which may or may not be connected to the grid. The speed of the flywheel increases and slows down as it stores energy and gets discharged
