Power Station Tauernmoos

Electricity from hydro power ensures environmentally friendly mobility. In the future, ÖBB-Infrastruktur will also count on the in-house generation of traction current with the planned Tauernmoos pumped-storage power station. Large peaks in the traction current network can be covered with the pumped storage method.

High environmental standards

ÖBB-Infrastruktur already operates four traction current power stations in Salzburg’s Stubachtal valley. Together, the power station group generates nearly 20 percent of the energy needed by the Austrian rail power network to power freight and passenger trains. In other words, almost every fifth train in the rail network runs on traction current from the Stubachtal. The authorities also issued the project with a positive environmental compatibility test (UVP) notification due to the high standards of nature conservation.

The UVP notification of Salzburg province covers water rights and nature conservation as well as all approvals required for power station constructions, including those of the Railway Act.

Optimal use of the 220 metre height difference between the reservoirs

The two reservoirs Tauernmoossee and Weisssee were constructed in the upper Stubachtal valley (municipality of Uttendorf) in the Hohe Tauern National Park, in the first half of the century. The Tauernmoossee has been used with the Enzingerboden power station to generate electricity (output 80 MW) ever since. The Weisssee, which is 220 metres higher, continues to serve as a pre-storage basin only. The drop height between Weisssee and Tauernmoossee has never been used. The new pumped-storage power station with two 85 MW turbines also enables this height difference of the reservoirs to be used to generate electricity for powering trains.

Information and coordination

The constructional realisation of the new pumped-storage hydropower station Tauernmoos is closely coordinated with neighbouring residents and municipal governments.
