The Ohle hydropower plant in Ohle near Plettenberg is one of ten run-of-river power plants (not including small systems) on the Lenne .
development
The plant was built for the Ohler Eisenwerk, which was founded in 1889 as Ohler Eisenwerk Achenbach, Kölsche & Co., in 1895 by Theob. Pfeiffer was taken over and essentially expanded by one of his sons, Walter Pfeiffer , who joined the company with his brother in 1919 after serving in the war. The growing plant quickly required more energy and so in 1923/24 the much more powerful Bockeloh run-of-river power plant near Werdohl was built as the second plant , but still had to buy the additional demand from the steam power plant at the Siesel hydropower plant . After the plant was sold, the power plant belonged to the Rio-Tinto-Alcan group. With its restructuring, the waterworks was taken over by Stadtwerke Mainz for 3 million euros in investment costs in 2009 and adapted to the requirements of the Renewable Energy Sources Act , including the construction of another fish ladder that bypasses the weir and overhaul of the weir. The technical systems and the machine house itself were last renewed in 2003.
Further technical data
The maximum installed power is around 450 kW. The dam wall is about 50 m long. The electricity is fed into the public grid. The Kaplan turbine from 2002 has a maximum output of 550 kW with a construction head of 3.50 m and a maximum absorption capacity of 19 m³ / s. The generator from Loher is a water-cooled three-phase asynchronous machine with a nominal output of 550 kW.
