The Hirschaid power plant in Strullendorf is a run-of-river power plant built in 1922. The power plant is located in the immediate vicinity of the Strullendorf lock on the Main-Danube Canal (at canal km 13.9).
In the upper reaches a 280 m long power station canal branches off from the Main-Danube Canal to the inlet. Three Francis twin turbines with three generators generate an output of 3.6 MW. The water volume of 50 m³ / s then flows through a 480 m long canal into the deeper flowing Regnitz .
The new Regnitz weir in Neuses, built in the course of the construction of the Main-Danube Canal, supplies the Regnitz from Neuses to Hirschaid with water, and at the same time regulates the water level of the Strullendorf canal . Water that is not required for the lock in Strullendorf is available to the Hirschaid power plant through the canal discharge.
The hydropower plant currently in operation consists of several buildings and is in the list of architectural monuments of the Bavarian State Office for Monument Preservation.
history
Since the Main-Danube Canal did not exist when it was built from 1921, a works canal was built by means of a dam on the Regnitz near Neuses, roughly parallel to the Ludwig-Danube-Main Canal to the power station and the Regnitz. The power station was built by the Becker & Co. railway company on behalf of Überlandwerk-Oberfranken in 15 months.
During the Second World War, the ÜWO-AG power plant was targeted by air raids and damaged by bombs on February 20, 1945, a senior machinist on duty was seriously wounded in the turbine house of the power plant and died a little later in the hospital in Bamberg.
Towards the end of the 1950s, measurements and an administrative manager established that the EVO power plant was actually completely within the boundaries of the Strullendorf community. Lost tax revenue (built in 1922) was paid retrospectively to the municipality for two years.
From 1964, the Main-Danube Canal to the west of Strullendorf replaced the old Ludwig Canal and the plant canal of the power plant, which until then fed the power plant from Neuses. A 700 m long part of the old works canal is still preserved as an industrial monument near Altendorf.
On the right side of the weir bridge of the power plant, a concrete drop barrier was installed in 1982, which was supposed to make the crossing unusable for military purposes. This relic of the Cold War is still there today as a memorial.
In December 2008, new Francis turbine runners with an optimized design were installed for the last time and the nozzles, turbine shafts and the mechanical control were renewed.
