124 MW Hydroelectric Powerplant from 1924: The Walchenseekraftwerk

The Walchenseekraftwerk Hydropower Station was built in 1924 about 100 km south of Munich in the Bavarian Alps. Four Francis Turbines and four Pelton Turbines produce a total Power of 124 MW from the 200 m Height Difference between the Walchensee and the Kochelsee Lakes.

Just found this channel today and i just want to say that these videos are lovely! Love being able to see and hear the raw footage while the text gives just enough context to understand what's going on.

Thanks for the great video! I remember this place! My parents came from Kochel, and I visited it many times. One of my relatives worked on the crew that tunneled through the mountain for the penstock intake from the Walchensee. There used to be a photo on display showing the miners when they broke through. Back in the 70's we rented a little pedal-driven boat on the Walchensee and were able to see the intake where the water flows into the mountain tunnel. Seeing the Walchenseekraftwerk when I was little is what made me get interested in electrical engineering. Glad to see it's still there and going strong after all these years.

I'm not too sure if I included that in the Video, but the Kesselberg Tunnel was inspected by the only German Research Submarine (named Jago) a few Years ago, IIRC shortly before the Jago was decomissioned. I grew up near Basel, where the Rhine is fairly steep between Schaffhausen and Basel and thus there are 11 Hydroelectric Dams on that 120 km Distance, ranging between 26 and 120 MW. The Rivers coming down from the Black Forest are some of the steepest in Germany (up to 1:42 Gradient), but they are nowhere near as large as the Rhine, hence the largest one has just a wee bit over 1 MW. The Pumped Hydro Plant in Wehr (Black Forest) is the third largest Hydroelectric Plant in all Germany though, at 910 MW. Anyway, visiting one of the Rhine Plants during a Turbine Overhaul was one of the Things that inspired me to study Engineering, and now I received my Marine Engineer License four Months ago.

Just a lovely hydroplant. Thanks!

There used to be another lovely one from 1898 on the River Rhine in Rheinfelden, partially in Switzerland but mostly in Germany. It was demolished about 12 Years ago, because German Environmentalists demanded so, and even the UNESCO couldn't save it. Very sad Story, I might make a Video about it when I get better at Speaking on Camera. There's another awesome one relatively close to the Walchenseekraftwerk, named Kraftwerk Töging. Luckily, that one is preserved as Museum.

@@Genius_at_Work Sad that environmentalists would want to demolish a hydroelectric power plant. It's got to be one of the cleanest and most environmentally benign ways of generating electricty. Too bad :-(

@@Genius_at_Work Enviros are idiots! Hydro is the absolute cleanest!

4:19 The loud "hum" is probably from the single phase generators. The rotary converters used to convert 50Hz to 16.7Hz has an almost identical "hum"

Excellent !! James.

I'm a big fan of Peltons because of the high efficiency. I know of a road near a river rapids and factory named Pelton Road. Suspect there used to be a Pelton mill there.

Awsome video!!!

[@SteamCrane]

There used to be a lot of 25 Hz railroad catenary in the US. The sound it makes is scary.

Note all hydro dams run one bank of turbines ,,,, In Australia RDP Marine has a system that lets most dams run two or three banks of turbines without surging or dissolved gasses issue

Head can manifest in three forms: pressure head, velocity head, and altitude head. I wonder why there are both Francis turbines and Pelton wheels in the same installation.

[@Genius_at_Work]

Probably because the 50 Hz and 16 2/3 Hz Generators have different Torque/Speed Characteristics. Plus in 1924, Power Stations like this were still a Novelty, so there was a lot more "Experimenting" going on than today. If you look closely, you'll actually see that even the "same" Generators are different; there are two Types of 50 Hz Generators and two Types of 16 2/3 Hz Generators. But that's for the simple Reason that the Contracts to build the Generators were equally split between the four large Electrical Engineering Companies of 1920ies' Germany, as Stimulus Measures following WW1 Defeat, Political Unrest and the 1923 Hyperinflation.

Doa war ich och scho mal. Die Aussicht von oben bei diesem Wasserschloss (Anfang Video) hab Ich damals auch genieße können. Hast du die NDR Doku gesehen , als sie da mit dem Uboot in den Druckstollen rin gefahren sind? nette Sache
