The St. Georgen power plant is a run-of- river power plant on the Mur in St. Georgen ob Murau , municipality of Sankt Georgen am Kreischberg , in Styria . It is operated by Verbund AG .
location
The power plant is located on the upper Mur , a little above Murau (river kilometer 385.9). It belongs to the cadastral communities Lutzmannsdorf and St. Lorenzen . The Kreischberg holiday park is located directly at the power station .
The storage space extends almost 2 kilometers up to Bodendorf , and is largely connected directly to the power station there.
history
The power plant was built between 1983 and 1985 by the Steirische Wasserkraft- und Elektrizitäts-AG (STEWEAG). The power plant went into operation in September 1985. Originally, a three-stage expansion between Stadl and Murau was planned, but only Bodendorf and St. Georgen were implemented. In 2002, Energie Steiermark (ESTAG), the state's energy holding company created in 1996, withdrew from direct electricity production , and the power plant was transferred to Verbund Hydro Power , the hydropower subsidiary of the Austria-wide Verbund AG, in exchange for holding shares.
For the 2nd National Water Management Plan (NPG) 2015, which continues to implement the EU Water Framework Directive (WFD), the power plant must be equipped with a fish pass.
investment
The power house with operations building, switch house and trash rack cleaning machine is on the right bank , the open-air switchgear is on the left of the Mur. The building is covered in earth and planted. The weir system of the run-of- river power plant has two fields with a clear width of 11.5 m each and a lock height of 8.5 m. The storage space is 836 m above sea level. A. , the underwater at about 821 m above sea level. A.
The five-bladed Kaplan - spiral turbine with a rated power of 6,364 kW at 50 m³ / s ability to swallow has an impeller diameter of 2.7 m, and was of the Maschinenfabrik Andritz prepared. Connected is an 8,500 kVA three-phase synchronous generator and a 3.5 to 30 kV machine transformer , both from ELIN . The electricity is diverted via 30 kV overhead lines to Kreischberg , Murau and the Bodendorf power station.
The power plant is unoccupied, it is controlled and monitored fully automatically by the process computer of the Bodendorf power plant, and thus forms the lower level of that run-of-the-river / storage composite power plant. In the machine house there is also a 160 kVA transformer from Siemens , the emergency power supply is in the power house in Bodendorf.
Nature and leisure
The storage space of the running power plant is fishing waters, and brown trout and rainbow trout and grayling occupied. With the continuation, a more natural stock should come about.
The facility is fully part of the European protection area Upper and Middle Rivers of the Mur ( FFH , AT2236000 / No. 5).
The Mur Cycle Path runs along the south bank of the reservoir ( right bank ) .
