Reisseck II Pumped Storage Power Plant
Mühldorf, Austria / 06.2010 - 09.2014
The new Reisseck II pumped storage power plant serves as an expansion to the existing group of power plants, Malta and Reisseck/Kreuzeck in Carinthia. It links the hydraulic systems of the power plant group, thereby optimising the use of resources. The power plant has a power output in turbine and pumping operation of 430MW.
The location of the construction site and the logistics presented the relevant teams with special challenges: in the Alpine area at heights of 600 to 2,400m above sea level, they built a sloped shaft with a gradient of 42° and a length of 820m using conventional shaft-sinking methods. A special avalanche warning system was set up for the 7km-long construction site in the Mühldorfer Graben area to protect the workers during the winter months.

Power plant construction at a 42° gradient.
The spectacular construction site attracted numerous sightseers and so the flows of visitors through the construction site also had to be organised.
Today the new, approx. 5km-long headrace consists of a 3.3km-long headrace gallery, a 0.8km-long pressure shaft, a 0.6km-long flat section and a 0.3km upstream distribution pipeline, via which the water flows into the new hydropower cavern.
What ultimately counts in the construction business is successfully completed projects. PORR has many of these.
