Oldau Lock and Historic Hydroelectric Power Station

In 1907, the Royal Prussian State decided the channeling of the Aller on a route between Celle and the Leineeinmündung at Hademstorf. The town of Celle was given the right to use the hydroelectric power generated by the dam. The usable slope is 2.80 meters. After completion, the hydroelectric power plant went on 16 April 1911 to the grid. 1929 was equipped with three Francis turbines Oldau hydroelectric power plant sold to the Preußen Elektra and operated by this until 1972. Following temporary closure, the imminent demolition by the district president in Lüneburg was prohibited and the facility declared a technical monument.

After a ten-year shutdown, the hydroelectric power plant was put back into operation. The annually produced electricity of about 2.5 to 3 million kilowatt hours is fed into the power grid. The Oldau hydroelectric power station is the only one of its kind that has been preserved in its original condition in Germany and supplies electricity to the grid.

Beautiful continuation forest and meadow area for horses. Even foals are born here. 😍
