Flywheel energy storage (FES) works by accelerating a rotor (flywheel) 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 an increase in the speed of th…
A flywheel is essentially a mechanical battery consisting of a mass rotating around an axis. It stores energy in the form of kinetic energy and works by accelerating a rotor to very high speeds and maintaining the energy in the system as rotational energy.

Energy Release: When the grid requires additional power (e.g., during peak demand or when renewable energy supply is low), the Flywheel Energy Storage System releases the stored energy. The spinning rotor transfers its kinetic energy back to the generator, which converts it into electrical energy and feeds it back to the grid.
