Bike Touring Highlight
The power plant Kachlet, also Kachletkraftwerk or Kachletwerk is operated by Uniper Kraftwerke GmbH dam with double lock and hydroelectric power plant in the Danube at Maierhof in the city of Passau.
The Kachlet, a section of the Danube in front of Passau, dotted with rocks and islets, has always hampered shipping traffic. So it was decided to overstep the nearly 20 km long danger route . For this purpose, the Rhine-Main-Donau-AG, founded in 1921, built a power plant with a double lock from 1922 to 1927. This was also the first step in the creation of the main shipping canal Main-Danube Canal.
Reservoir [edit | Edit]
The system accumulates the water level up to a height of 9.2 m above low tide. This ensures a minimum driving water depth of 2.5 m. The weir is 175 m long  with six openings of 25 m in width and double surface shooters of 11.8 m in height. Both lock chambers are 230 m long  and 24 m wide . Each lock requires 40,000 m³ of water. The mean water discharge is 648 m³ / s, the highest water outlet 6000 m³ / s .
The storage space in front of the power plant is 28 km long  and protected by dams. The Sollstauziel is located at 299.8 m above sea level. Sea level . The terrain behind the dams is drained by eight pumping stations. In September 1925 ships sailed through the lock for the first time. On 9 May 1933, the reservoir was the scene of the sinking of the flying boat Do X.
Powerhouse [edit | Edit]
The powerhouse is 144 m long, 17 m wide and has a height of 20.6 m. The original propeller turbines were replaced after about 35 years by Kaplanlaufräder with adjustable blades. The ability to swallow could thus be increased from 750 m³ / s to 1070 m³ / s. The expansion capacity thus increased from 42 MW to 53.7 MW and power generation from 260 GWh / a to 308 GWh / a.
