Hydro Power Plant Tannuwald, Retrofit, Lot 13 Cables
The existing hydroelectric power plant Tannuwald has been commissioned in 1981 with an installed power output of 5 194 kW. The power plant is located at 1 391 m a.s.l. in the canton of Valais (Switzerland). The Fah reservoir (41 000 m3), which is located about 2 790 m upstream the power plant, collects the water at an elevation of 1 758 m.a.s.l. After flowing through the penstock, the water is turbined in 7 pumps operating as turbines. In the frame of the retrofit project Tannuwald, the 7 units will be replaced by 2 identical vertical Pelton groups. The existing 16-kV-cable connection from the Tannuwald power plant to the Sera substation will be replaced by a new one. Between the power plant and the Fah reservoir, a new 16-kV-cable connection is created along the penstock. A new cable connection will be made for the 400-V supply to Alp Cheller from the Fah reservoir.
