Warmatsgund pumped storage power plant
The Warmatsgund pumped storage power plant is a hydropower plant in Oberstdorf- Warmatsgund, which was also used at times as a pumped storage power plant, but currently only as a run-of-river power plant . It was built between 1989 and 1992 and inaugurated on September 18, 1992.
The hydropower plant in the lower basin has a twin-jet Pelton turbine from Voith with a nominal output of 4.72 MW . This is achieved with an expansion water volume of 1.45 m³ / s, a usable head of approx. 374 m between the upper and lower basins and a speed of the turbine and the generator of 750 revolutions per minute. the annual standard work capacity is approx. 14 million kWh . The lower basin at approx. 920 m above sea level and the upper basin at approx. 1,300 m above sea level both have a basin volume of approx. 25,000 m³ each.
The water flows into the upper basin of the Warmatsgund power plant from the Warmatsgundbach via a Tyrolean weir . It has a dam as a barrier structure. The water area is around 10,000 m². From the intake structure a tunnel runs 160 m deep vertically downwards, followed by a 1,650 m long inclined tunnel . In addition to the Warmatsgundbach, which is a tributary of the Stillach , the Scheidtobel is also led with a transition from the southern Fellhorn area into the upper basin, as is the Schlappoldbach. Debris and flooding are directed past the upper basin in a channel.
The Warmatsgund power plant is controlled remotely from the Oberstdorf central control room during normal operation. It is operated by Energieversorgung Oberstdorf GmbH . The Warmatsgund power plant alone supplies around 25% of Oberstdorf's electricity needs .
