Even in the middle of the 19th century, the utilisation of the hydraulic power at the Herbede plant was desired regenerative source of energy for the powering of the first set of rolls in the sheet rolling factory. This direct powering was given up in 1992 with the changeover from an isolated operation to a network countershaft transmission. Today, a total of 4 turbines are operated by hydraulic power. This makes it possible to power the network around the clock. Altogether, approximately 4.5 million KWh are generated per year.
