September 18, 2025, Diemeltalsperre Hydroelectric Power Plant

At the upper reaches of the Diemel River, in Helminghausen, we encounter the massive dam of the Diemel Dam. A 35-meter drop is used here to operate two Francis turbines. The power plant below this dam was built between 1920 and 1922. Since 2000, it has been operated by E.ON Energie AG, formerly Preußen-Elektra in Hanover. Following restructuring and spin-off measures at E.ON in 2016, Uniper SE operates the power plant, which reports directly to the Edersee utility management. The substation is housed in the four-story power plant building. Here, the three-phase current generated at a voltage of 8 kV was transformed in various ways and fed into the Hessian 60 kV line to Hemfurt am Edersee and a 24 kV line to Heringhausen (Waldeck), as well as into the 60 kV line of the Büren-Brilon Electricity Association. From here, electricity was also supplied to the local grids of Helminghausen, Padberg, and Messinghausen. Two transformers in the basement provided the conversion for the Brilon district. The oil switches were located on the ground floor, the collector slides on the first floor, and the surge protection on the second. This is where the cables entered and exited. This explains why there is no transformer house in Helminghausen, as the transformer was housed directly in the power plant's substation. The municipality of Helminghausen only had to erect 25 wooden poles, each 10 meters long and with a 20-cm diameter, for the power grid. The front section of the power plant, with its striking three-axis window front, houses two three-phase generators from Siemens-Schuckert. Today, thanks to technical improvements, they each have an output of 500 kW (760 hp). They went into operation in 1924. Behind the building are the bottom outlet tunnels of the dam, from which the inlet pipe leads, supplying 4,500 liters of water to the turbines every second. The power plant has a capacity of 1.2 MW. The substation, the first in the Hochsauerland region, was commissioned as early as August 1922. Source: https://helminghausen.net/kraftwerk/

The hydroelectric power plant has been in operation since 1924. Inside there are two 1MW turbines that generate 2.5 GWh of green electricity.

From the Diemelsteig you will have wonderful views of the Diemelsee. But be careful: the viewpoints are not always directly on the path, but it is always worth taking the small detour.

The Diemelsteig runs on a section of the panorama trail. Nice to walk, it overcomes a few meters in altitude and rewards the hiker with beautiful views and a springy forest floor!
