Häusling storage power plant

The Häusling pumped storage power plant is located in the town of Brandberg in the municipality of Mayrhofen, in a picturesque side valley of the Zillertal in the province of Tyrol.

The water reservoir of the VERBUND power plant is the Zillergründl reservoir at 1,850 metres above sea level – one of the many attractions in the region, in addition to the beautiful features of the Zillertal Alps Nature Park. 

The Roßhag, Häusling and Mayrhofen power plant group is one of the most powerful storage power plant groups in Austria. The combination of storage and pumped storage power plants makes the three power plants indispensable as balancing and standard energy suppliers for the Austrian and European grid.

Environmental protection at VERBUND
Sustainable Rivermanagement is a project under the scientific direction of the University of Natural Resources and Life Sciences and e3 consult, which VERBUND Hydro Power GmbH co-financed as one of the consortium partners. 
Achieving the environmental targets of the EU Water Framework Directive is just as essential for national climate targets as it is for the implementation of the EU’s energy and climate packages. Over many years of cooperation between science, power generation and the authorities, the understanding between the interest groups has been deepened and meaningful, efficient solutions for the implementation discussed. A method has been developed for comparing the ecological effects or the ecological improvement potential of individual surge-absorbing measures with the corresponding system-relevant as well as economic and business effects. Further information about the project can be found on the website of the Federal Ministry for Sustainability and Tourism.

Fish bypass

The long side of the Häusling powerhouse was built into the steep rockface. Two sets of machinery with a vertical shaft (total height approx. 40 metres) and a total bottleneck power of 360,000 kW are installed in the powerhouse, each consisting of a motor generator, a Francis turbine as well as a two-stage, single-flow pump and a hydraulic converter. 

The energy is raised to high tension with a 220 kV indoor switchgear and transmitted via a 220 kV overhead line to the Mayrhofen outdoor switchgear.

Zillergründl reservoir: The Zillergründl reservoir has a usable capacity of 86.7 million m3 and is located 1,850 m above sea level. The closing structure is a double-curved arched wall.
