The power plant Kachlet even Kachletkraftwerk or Kachletwerk is one of the Uniper Kraftwerke GmbH operated 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 littered with rocks and small islands, has always hindered shipping traffic. So the decision was made to flood the almost 20 km long dangerous route. To this end, Rhein-Main-Donau AG , founded in 1921, built a power plant with a double lock between 1922 and 1927. This was also the first step towards the creation of the Main-Danube Canal large-scale shipping route .
Reservoir
The system dams the water level up to a height of 9.2 m above low water. This guarantees a minimum fairway depth of 2.5 m. The weir is 175 m long with six openings each 25 m wide and double gates 11.8 m high. 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 passage 6000 m³ / s.
The storage space in front of the power plant is 28 km long and secured with dams. The target congestion target is 299.8 m above sea level. Sea level . The area behind the dams is drained by eight pumping stations. In September 1925 ships passed through the lock for the first time. On May 9, 1933, the reservoir was the scene of the accident of the Do X flying boat .
Power house
The power house is 144 m long, 17 m wide and has a height of 20.6 m. The original propeller turbines were replaced by Kaplan runners with adjustable blades after about 35 years . The swallowing capacity could thus be increased from 750 m³ / s to 1070 m³ / s. The expansion capacity rose from 42 MW to 53.7 MW and electricity generation from 260 GWh / a to 308 GWh / a.

ship
A motor ship from the Passau Waterways and Shipping Authority , registration number Pa 11-D3, used in 1955 as an icebreaker in the Danube between Passau and the Jochenstein power station , was called Kachlet.
