The Nethe water storage power plant was a planned pumped storage power plant near Amelunxen in the area of the North Rhine-Westphalian cities of Beverungen and Höxter in the Weserbergland , shortly before the eponymous Nethe flows into the Weser . In July 2018 it was decided not to go ahead with the project.
The plant was to have 4.2 million cubic meters of storage volume and the power plant had an output of 390 megawatts .
It was one of several projects of the European energy supply company Trianel , a network of 35 municipal utilities from Germany , Austria and Switzerland .
purpose
With the pumped storage power plant, the temporarily generated excess electricity from renewable energies should be stored in order to be able to release it again in times of increased demand. Up to 2.34 million kilowatt hours can be stored in the form of potential energy in a high water basin on a hilltop. It takes six hours to pump up the amount of water from the lower basin and also six hours to drain it again under full load through the turbines . Depending on your needs, you can switch between pumps and turbines. It was expected that the hydropower plant would provide electricity for around 2,500 hours a year. One tank filling corresponds to the annual requirements of around 670 households.
Technical specifications
The power plant was planned as a shaft power plant with turbines at a depth of around 80-100 meters.
The upper basin would be located between Ottbergen and Bosseborn, the lower basin northeast of Amelunxen. The operating volume and thus the storage volume of both basins would each be 4.2 million cubic meters. The water surface of the upper and lower basins would be 22 and 46 hectares respectively . The upper process water level of the upper basin would be 343 meters, the upper edge of the dam at 345 m above sea level. NHN . At the lower basin it is 113 meters and 115 meters respectively. The average hydraulic head would be 223 meters and the flow through the pipes and turbines would be about 195 cubic meters per second.
The planned pumped storage power plant with 390 MW would have been a medium-sized one compared to other pumped storage power plants, see list of pumped storage power plants . Since December 2011, the procedure to change the regional plan has been in progress, with plans to bring the power plant online in 2021. In July 2018 the project was abandoned on economic considerations.
