The Ruetzkraftwerk ( Ruetzwerk ) is a hydropower plant in the municipality of Schönberg ( Tyrol , Austria ), which was used by the ÖBB between 1912 and 1983 to generate traction current . It has been owned by Innsbrucker Kommunalbetriebe AG since 1984 . It uses the energy from water diverted from the Ruetz , the river that flows through the Stubai Valley .

Location and buildings

The Ruetzwerk is located about 8 kilometers south of Innsbruck city ​​center and 2 km north of Schönberg. It lies at 707  m above sea level. A. Height to the right of the Ruetz.

The houses form as rotting own local situation of the community Schoenberg. They can only be reached from Unterberg on Brenner Straße  (B 182, Stephansbrücke ), behind the plant (= south, above) the impassable Ruetz Gorge ends , through which only one hiking trail leads.

The engine house is a listed building , as is the valley standing house Direktorenvilla .

History and technology

The Ruetz power plant in Schönberg was built from 1909 to 1912 and expanded from 1920 to 1923. It used the hydropower in the Stubai Valley with a catchment area of ​​283 square kilometers in the lower reaches of the Ruetz with a catchment just below Fulpmes. An aqueduct , namely a free mirror tunnel , led to Schönberg, where 175 meters of usable head were used up to the power station near the Stephansbrücke . The initial expansion featured a pressure pipe power train with two 4000 HP Pelton turbines and 3300 kVA generator sets. The power plant was expanded to include a second surge tank , a second pressure pipe and a third generator with an additional output of 8,000 hp. A compensation basin stored 2770 m³ (before the expansion; designed for a four-hour operation of the Mittenwaldbahn) or 7600 m³ (after the expansion; corresponding to 2280 kWh) of water.

The upper water systems of the Ruetz power plant were installed at the same level as the Obere Sill power plant of the city ​​of Innsbruck , so that reciprocal head water relief was possible.

Initially, the Ruetz power plant was solely responsible for the power supply of the Mittenwald Railway in Austria and Bavaria. After the expansion in 1923, it was also used for the electrical operation of the  Arlbergbahn  . With the construction of the Walchensee power plant in 1924, the Ruetz power plant lost its function for supplying electricity to Bavaria.

In 1983 the old Ruetz power plant for traction power generation was replaced by the new Fulpmes shaft power plant , which was built from 1977 to 1983. The headwater is collected below Fulpmes in the Stubai Valley. The installed capacity is 15 MW, with two Francis turbines operating at a gradient of 182 m.

The shutdown of the Ruetz power plant in Schönberg was acquired in 1984 by the then Stadtwerke Innsbruck (today Innsbrucker Kommunalbetriebe), as it can be used to reduce the empty shot due to the hydraulic coupling of the two water locks to increase the output in the Sill power plant with the new Matrei-Schönberg headrace tunnel. The power plant was commissioned by Innsbrucker Kommunalbetriebe  (IKB) after renovation and revitalization in 1997 for the public power supply (50  Hz ).

One of the first two machine sets (turbine and generator) from 1912 was installed in 1995 in the Technisches Museum Wien  (TMW), where the system can be viewed from above as well as from the basement of the machine house, whereby the turbine housing can also be seen from the inside .
