Hydropowerplants Innertkirchen 1 & Handeck 2 / Switzerland
Customer: Kraftwerke Oberhasli, Schweiz
The hydro-power-stations Innertkirchen 1 and Handeck 2 are to be upgraded to state of the art. By constructing a second head-race tunnel parallel to the existing one, the velocity of flow and thereby the losses of friction are to be reduced allowing to equip both power-plants with a second unit each and increasing the capacity to total 280 MW.
