The hydropower plant on the Stadtbach uses the hydropower of the Augsburg Stadtbach , which is one of the Lech canals in Augsburg . It was built to operate the cotton spinning mill on the Stadtbach , produced electricity for the spinning mill and today generates electricity for the public grid.

The power plant is the oldest of a total of three hydropower plants that have belonged to the spinning mill over the years. The other two are the hydropower plant on the Wolfzahnau and the hydropower plant on the Proviantbach . It is a protected architectural monument and part of Augsburg's historic water management system , which was declared a UNESCO World Heritage Site in 2019 .

location

The hydropower plant on Stadtbach is located north of Augsburg's old town in the district of Rechts der Wertach in the Augsburg-Oberhausen district . It is not located on any street, but in the middle of a commercial area that is enclosed on three sides by Sebastianstraße, Stadtbachstraße and Franz-Josef-Strauss-Straße.

The Stadtbach divides this area into two different industrial areas. The cotton mill used to be located in the area between the Stadtbach and the Proviantbach . Today it belongs to the paper manufacturer UPM-Kymmene . On the east side of the Stadtbach, tracks of the Augsburg Local Railway run right past the hydropower plant.

The area on the other, south-western side of the Stadtbach was previously used by the Augsburg-Nürnberg machine works (MAN) . The factory halls of its successor, MAN Energy Solutions SE, are built right up to the Stadtbach and the hydropower plant on the Stadtbach.

history

predecessor

The power plant, which is still in operation today, was created as a new building, but in terms of hydrotechnology and water law through a merger of two predecessors.

In 1846, the entrepreneur Ludwig Sander applied to the municipal authorities of Augsburg to correct the course of the Stadtbach when purchasing the area between Stadtbach and Proviantbach . Work began the following year. In 1851 the Spinnerei am Stadtbach was founded as a stock corporation. The magistrate transferred the water rights to her on June 3, 1852 (designation: Wasserrecht 50). The planning and execution of the first hydroelectric power plant on the factory site, approx. 150 meters south of the current power plant's location, proceeded rapidly. This first power plant on the Stadtbach was built with an ice creek or ice canal, which discharged the ice that came in winter into a branch of the canal. In 1853 it went into operation, and with it the spinning mill.

In the cotton spinning mill at Stadtbach, raw cotton was spun into yarn on a large scale . In 1865, 1200 employees worked with a total of 95,000 spindles and achieved a turnover of five million guilders . The Augsburg cotton spinning mill on Stadtbach was the largest spinning mill in the territory of the German Customs Union . The intensive use of the water power of the Stadtbach made the operation possible in the first place and served as a role model.

Another power plant (Wasserrecht 49) worked on the nearby, smaller Malvasierbach canal, which flows into the Stadtbach, until the beginning of the 1870s, and was also attached to a factory building. The associated water rights of the two power plants were combined with the construction of today's power plant on the Stadtbach. This means that two power plants have been combined into one more powerful large-scale power plant.

Built in 1873–1875

Site plan of the cotton mill on the Stadtbach, 1874. The hydropower plant on the Stadtbach is on the top left, directly after the confluence of the two canals. The Malvasierbach is built over today, but is still there.

The Augsburg company Thormann und Stiefel was commissioned with the construction. The new power plant on the Stadtbach bears the designation 49/50 in the city's documents, which refers to the two originally existing water rights.

It is unclear whether the hydropower plant was used for transmission drive when it was built or whether electricity was already being generated by a generator .

20th century

In 1907 the power plant was rebuilt and a generator from Siemens-Schuckertwerke was used. The spinning mill was transferred to the Dierig Group in the 1930s .

In the 1990s Dierig sold the power station, after which it was technically converted. Two Kaplan turbines with vertical shaft and two generators from the Austrian company Kössler were put into operation. The energy gained is now fed into the public power grid. To date, a maximum of 16.20 cubic meters of water per second flow through the two turbines at a height of 3.95 meters. The maximum output of the two twin turbines is given as 825 hp.

The old generator from Siemens-Schuckertwerke is still preserved as a showpiece.

architecture

The hydropower plant was originally built as a free-standing structure. Later the MAN factory halls were built up to the power station.

The single-storey solid building made of red and yellow exposed bricks with a flat roof and arched windows, which is structured by brick arched friezes, corner pilasters and lintels, was built between 1873 and 1875 on an angular floor plan and expanded in 1907.
