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.

Learn MoreEnergy storage in flywheels. A flywheel stores energy in a rotating mass. Depending on the inertia and speed of the rotating mass, a given amount of kinetic energy is stored as rotational energy. The flywheel is placed inside a vacuum containment to eliminate friction-loss from the air and suspended by bearings for a stabile operation.
