Unlike common storage power plants, such as the pumped storage power plants with capacities up to 1000 MW, the benefits from flywheel storage power plants move in the range of a few kW to several 10 MW. They are comparable in this application with battery storage power plants.Possible areas of application are places where stored electrical energy and must be submitted again to compensate for example, fluctuations in the seconds range in wind, solar. These storage facilities consist of individual flywheels in modular design. Excellence to 150 kW can be absorbed or released Pro flywheel. Through combinations of several such flywheel accumulator, which are individually housed in buried underground vacuum tank, so total power of up to several 10 MW can be achieved. The electrical connection of powered with low voltage motors is via a DC intermediate circuit and the power converter systems are comparable as they are with plants also in the high-voltage direct current transmissions application. Sometimes battery storage power stations are built with flywheel storage power systems in order to conserve battery power. Flywheels can handle rapid fluctuations better."@en }
