In upgrading the Aller between Celle and the mouth of the Leine near Schwarmstedt between 1908 and 1918, hydropower stations were built at two of the four new barrages: Oldau and Marklendorf.
They enabled the electrification of the Südheide.
The Oldau station, with three Francis turbines, was taken over in 1929 by PreussenElektra.
In 1972, the power stations were closed as they were unprofitable.
Whilst the structure in Marklendorf was demolished, the power station in Oldau was declared a technological monument and escaped destruction.
After being modernised in 1983, it rejoined the grid.
It has largely been preserved in its original state.
Here, the water power of the Aller, with the aid of Francis turbines with a nominal power of 650 kW, is used to generate 3 million kWh per year of electric current.
