A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That''s 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for about 10 minutes. I think you might be over-estimating how much energy these things can store. – Tim.

If more energy storage is required from the flywheel, then multiple flywheels must be used. If multiple flywheels are used together, the mass, energy storage, cost, and losses are increased by a factor equal to how many flywheels are connected together and added to the fixed cost and mass of the ancillary flywheel equipment. If the

The 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.
