Tunnel Day

The Austrian National Committee of the ITA (International Tunneling Association) organizes the Austrian Tunnel Day in conjunction with the Geomechanics Colloquium. The Tunnel Day focuses on presenting the latest state of the art of Austrian and international engineering concepts in design and construction.

Recent creative developments in design, construction, and operating methods in tunnelling are presented.

The application of those new design and construction concepts will promote further innovation in future tunnelling projects.

LIMBERG III PUMPED STORAGE POWER PLANT

VERBUND Hydro Power GmbH (VHP) started construction on the Limberg III power plant in 2021.

Preliminary Program:

  • 08:00  Departure Salzburg Congress
  • 09:30  Arrival at the main construction camp Limberg III
  • 09:45  Project presentation and site inspection upper stage (Drossen)
  • 12:00  Lunch Break
  • 13:00  Site inspection main stage (Limberg)
  • 14:30  Departure main construction camp Limberg III
  • 16:00  Arrival at Salzburg Congress

 

The project, which was approved in 2017, is a pumped storage power plant with a total capacity of 480 megawatts. Like Limberg II, which was put into operation in 2011, it will be constructed entirely underground between the two existing reservoirs of the Mooserboden (final level 2,036 m) and Wasserfallboden (final level 1,672 m).

These two reservoirs with a total capacity of 160 million m³ will be used as upper and lower basins for the pump turbine operation to generate electricity. This is an addition to the existing power plants Limgerg I and Limberg II which are already in operation

The new headracetunnel starts at the intake of the Mooserboden reservoir and reaches the pressure shaft after 3.7 km. After a length of 600 m the pressure shaft leads via two distribution pipes into the underground power station, which is located underneath the Limberg dam. The power station consists of a machine chamber with two 240 MW hydroelectric sets and a transformation chamber, connected via two generator dissipation tunnels. After the turbines the water is returned  to the Wasserfallboden reservoir via a 613 m long tailrace tunnel.

In the powerhouse cavern, two hydroelectric sets generate electricity, each consisting of a reversible Francis pump turbine and a generator. The energy is dissipated with a nominal voltage of 380 kV from the cavern system by means of a gas insulated line and is connected to the existing energy dissipators.  

Upon completion, Limberg III will be a power plant whose design is tailored very specifically to the future needs of the energy transition. Special machine sets with variable speed-controlled pump turbines will be used that are able to react with extreme flexibility to the increasing need for balancing and controlling energy in the grid. Given the increasing requirements caused by the expansion of volatile forms of energy generation, these are important services for grid stability – one of the main prerequisites for a safe and affordable electricity supply.

In addition to being constructed underground, and thus out of sight, the overall project also encompasses a large number of ecological measures. A special highlight is the construction of the 24 hectare European conservation area “Alpine Alluvial Land Drossen”, which extends into the Drossen ravine. Below the dam, a project will also be implemented that aims at eliminating traces of the construction period of the 1950s by means of land restoration.

Technical Facts

  • Medium head 365 m
  • Number of pump turbines 2
  • Pump turbine capacity 2 x 240 MW
  • Flow rate per pump turbine 72 m3/s
  • Height of hydroelectric generating set 18,5 m

Sight Seeing Programm

On Thursday, October 8th, we are offering accompanying persons the following social program:

The Attersee is the largest lake in the Salzkammergut and, thanks to its turquoise blue water of drinking water quality, is one of the most popular bathing lakes in Austria. In addition to various sports opportunities, the region also offers numerous  attractions.

First, our tour leads to the beautiful late Gothic parish church of Gampern, where you can admire one of the three most famous Gothic winged altars in Upper Austria.

Then we go to Seewalchen where we visit the Gexi Tostmann traditional costume museum.

Afterwards we enjoy a walk on the promenade with a view of the lake, passing Villa Paulick, a historic summer villa that is a listed building.

A visit to the Klimt center in Schörfling, a walk on the Klimt theme trail, in the Klimt garden and a boat trip on Lake Attersee open up the Klimt trails and its impressive motifs on land and from the sea side.

Of course, lunch as well as coffee and cake are also provided.
