During discharge the process reverses: the rotor slows and the generator converts rotational energy back to electricity. This instantaneous conversion enables response times measured in seconds or less, making flywheel systems ideal for grid stability tasks. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm.
