Jettenbach I Run-of-River Plant

The Jettenbach VERBUND power plant is a dam on the Jettenbach and is located in the municipality of the same name in Upper Bavaria.

Technical Description 

The Jettenbach I power station was completed and inaugurated in 1924. It dams the river Inn 8 km downstream - at 128 km the water is channelled through the protection areas into the canal. The weir system has six openings with a width of 17 metres. A single rotor Francis turbine processes a minimum water volume of 5 m3/s and generates an average annual output of around 1 GWh of electricity. The weir furthermore covers a rate of flow of 4.000 m3/s. Additionally, a fish climbing aid is also currently being planned.
