The Leinau hydropower plant is a small hydropower plant on the Wertach and is designed as a run-of-river power plant without storage. The power plant is located near Pforzen -Leinau in the Ostallgäu district , a few kilometers downstream from the city of Kaufbeuren . It dams the Wertachgraben, which branches off at the hook bridge at the Kolb weir, over a length of 1.7 kilometers. The canal flows into the Wertach again about 600 meters below the power plant. The operator of the power plant is the United Wertach Electricity Works (VWEW).
history

The Kaufbeuren city council dealt with the planning of a hydropower plant for Kaufbeuren for the first time in 1916. The groundbreaking ceremony for a Wertach Canal in Leinau took place in 1920. With up to 184 workers, the 2.3 kilometer long canal was mostly dug by hand until 1923. The construction work on the "Untere Wertach" construction site turned out to be problematic during the currency crisis. Construction managers appeared armed to the construction site. In 1923, workers set fire to the hut in which the generator, which had not yet been assembled, was stored in order to sell the generator's copper. In order to secure the financing of the construction, two million kilowatt hours of electricity were sold for one billion Reichsmarks as a bank loan after a city council resolution in 1923.
In 2003 the power plants were completely renovated, and the turbine and generator were also replaced. The old generator was preserved as a memorial in the power plant's machine house. In 2006 a fish pass was built.
Leinau diesel power station

In addition to the water turbine, a diesel power plant with three motors with 4,400 kW each is installed on the premises, which are usually preheated around the clock in stand-by mode as a load reserve.
