The Steyrbruchbruch power plant ( Molln municipality ) has been a run-of- river power plant on the Steyr River that has existed since 1908 . The Art Nouveau architecture and power plant technology from the beginning of the 20th century have largely been preserved.
History and technology
The Kirchdorferfeld cement plants Hofmann & Co (from the Kirchdorferfeld group was) left the Art Nouveau plant in Steyr breakthrough -Schlucht of April 1907 set up to November 1908th The architect was Mauriz Balzarek , the executing company A. Buss & Co from Graz , a subsidiary of the Swiss company Albert Buss & Cie. With two machine sets of 700 kW each, the power plant was one of the most powerful systems at the time. In 1922 it not only supplied electricity for the Kirchdorf cement works and the surrounding communities, but even for the Linz tram . In 1936 and 1937 the storage space silted up, which made it necessary to convert the weir system. Since 1972, a Kaplan turbine with a capacity of 1.605 megawatts has been added to the three old Francis turbines with a total of 2.430 megawatts in a cavern next to the old power house . The power plant has been operating automatically since 1979/80. It is an Upper Austrian industrial monument , in 2008 Energie AG received the Monument Preservation Prize of the State of Upper Austria for its renovation and maintenance .
The control panel and the generators with the windings that are visible are from 1908 and the three Francis turbines from 1908 and 1925. The water reaches the fine screen through an upstream channel and then falls 13.6 meters onto the turbine blades. The reservoir in the narrow river valley is around 1.5 km long. Since the Steyr was still used as a wooden drift at the time it was built, the 13.6 meter high and 43 meter long weir system is equipped with a drift slide. This is designed for 6 to 6.5 meter long logs. The power plant is operated by Energie AG Oberösterreich and produces 20 million kilowatt hours of electrical energy annually . It supplies the communities of Molln, Sierning , Kirchdorf and Klaus .

architecture
The turbine house is a two- or three-story building with a tower-like corner structure and a hipped roof with glazed roof tiles. The facade is structured by pilasters , interrupted by a large cornice above the ground floor; the upper floor is closed off by a wave-like, curved eaves cornice. The windows on the ground floor between the pilasters are large. The raised corner tower bears the inscription in large letters: "ELEKTRIZITÄTSWERK / STEYRDURCHBRUCH / HOFMANN & COMP". The arched bridge over the Steyr River has two Art Nouveau pylons and a perforated railing. The individual sections of the heavyweight wall of the weir system are connected by filigree walkways, these take up the arch shape on their underside and thus stand out from the defensive wall.

Location
The ORF sports editorial team filmed an interview with Michael Hayböck in front of the backdrop of the power plant in 2016 . This interview was broadcast in the preliminary coverage of the Four Hills Tournament . The power plant is also one of the scenes in the country crime novel The Dead in the Lake .
