The flywheel system was required as an onsite power supply for fusion pulse experiments, which require a high amount of energy that was unavailable on the grid in Prague.

The fusion equipment (COMPASS-D tokamak) was previously used in UKAEA, United Kingdom. The equipment required electrical input power of 50 MW for pulse duration for about 2-3 seconds during operation. Such power was accessible in Culham Laboratory directly from the 33kV grid.

However, only 1 MW power is available from the 22kV grid at the campus of the Academy of Sciences in Prague, where IPP Prague is located. Therefore, several solutions to provide the necessary input power were considered. Installation of two flywheel generators was chosen as a solution. They provide the necessary power (70 MW, 100 MJ) as well as a reasonable redundancy in case of flywheel system failure.
