Such a plant is also called energy storage power plant. An energy storage power plant can be designed as a micro plant, as a plant of small and medium power up to a large plant for storing and delivering electrical energy of several megawatts per hour, even several thousand megawatt per hour.

The magnetic working means, such as a permanent magnet, is known to circulate as a runner in a closed conveyor system between the predefined high level and the predefined low level to store energy by converting electrical energy into potential altitude energy or converting stored energy to electrical output energy, depending on the operating condition ,

A method and a device for exploiting stored potential energy when unloading goods is for example from DE 26 18 046 A1 known.

The US 2011/0 278 856 A1 shows a shock absorber for power generation. The shock absorber includes an elastic member, a gear set having a first non-return gear and a second non-return gear, and an electric generator driven by the first non-return gear to generate power when the elastic member is compressed.

From the DE 10 2008 003 693 A1 is a mechanical Hubspeicherkraftwerk with gear hub known. A runner is guided along a substantially vertical conveyor line.

The US Pat. No. 7,847,421 B2 shows a system for generating electrical energy from motive energy from the environment, with a generator for converting motion into electrical energy and with a kinetic energy conversion system to convert the movement into stored potential energy. The generator has a first magnet coupled to the first biasing element in the form of a coil spring. The biasing element allows resonant vibration of the first magnet relative to the coil to generate an electrical current in the coil. The energy conversion system includes a second biasing element that can be pushed from a rest position to a clamping position to store potential energy.
