A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.

Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly results in ...
Flywheels can absorb energy by rotating faster and release energy by giving away their rotation into something else. Flywheel Energy Storage (FES) Instead of using large iron wheels and ball bearings, advanced FES systems have rotors made of specialised high-strength materials suspended over frictionless magnetic bearings capable of spinning at …

It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage. Unlike common storage power plants, such as the
The flywheel continues to store energy as long as it continues to spin; in this way, flywheel energy storage systems act as mechanical energy storage. When this energy needs to be retrieved, the rotor transfers its rotational energy back to a generator, effectively converting it into usable electrical energy.
