The Walchensee Hydroelectric Power Station, in operation since 1924, is located in Kochel, Bavaria (Germany) and was designed and developed by Oskar von Miller (1855-1934). The power station uses the height difference of about 200 m between the higher lake (Walchensee) and the lower lake (Kochelsee) to operate. The water flows with a maximum throughput of 84m3/s through 6 pipes down to the Kochelsee, where the power station is located. The 4 turbines in the foreground are of type Francis with three-phase generators (biggest in the world by that time) and 4 of type Pelton with single-phase generators located in the background. The water flow goes from left (water inlet) through the turbines to the right where the generators are also located.
