history

The Obere Sill power plant was built between 1901 and 1903 according to plans by Josef Riehl and put into operation on October 7, 1903. At the time of its construction it was one of the largest power plants in the Danube monarchy .

During the construction, a tender for the delivery of the pipes was made, which the Prague mechanical engineering corporation formerly Ruston & Co won. The pressure pipes were made from mild steel sheet supplied by the Teplitzer Rudolfshütte. The electrotechnical equipment and the high-voltage network were built by the Österreichische Union-Elektrizitätsgesellschaft.

The electricity generated here was mainly used to operate the funicular to the Hungerburg , the Stubaitalbahn and the first tram line from Innsbruck .

From the 1960s the Brenner motorway (A12) and 1959–1963 the Europe Bridge was built here. Since then, the place has come into the public eye several times through suicides .

technology

The water required for operation is taken from a tunnel at the north end of Matrei am Brenner der Sill and then fed back to a sand trap in the moated castle via two sand traps and a short channel in an approximately 7-kilometer-long tunnel . This is where the two pressure pipelines begin, each with an inner diameter of 1,250 millimeters and a drop height of 185 meters. About halfway up, the two pipelines cross under Brennerstrasse in a 93-meter-long tunnel.

Six twin turbines, each with directly coupled generators, were installed in the power house. Between 1926 and 1928, these machine sets were replaced by three new Pelton machine sets for three- phase power generation. A total output of 18  megawatts is installed.

Since 1986 a new headrace tunnel with a delivery volume of 15 cubic meters of water per second has replaced the originally constructed tunnel. Another tunnel enables the headwater to be forwarded to the Ruetz power plant .
