When generation exceeds load, the ISO's regulation dispatch control signal directs the flywheels to absorb energy from the grid and store it kinetically by spinning the flywheels faster. . What is a flywheel/kinetic energy storage system (fess)? Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining. . The ISO monitors the frequency of the grid, and based on North American Electric Reliability Corporation (NERC) frequency control guidelines the ISO decides when more or less generation is needed to balance generation with load. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage.
