Regenerative drives and motors unlock the power of flywheel energy storage …
The ABB motor and drive takes excess electrical energy from the grid and uses it to speed up the rotation of the flywheel, so it is stored as kinetic energy. When a fast injection of power is needed to maintain frequency stability, the regenerative capability of the drive converts the flywheel''s kinetic energy back into electricity within milliseconds.

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…
