    Field Trips

    We are planning the following field trips:

    Monday 9.10.2023 field trips: PSW Kühtai / Semmering Base Tunnel
    Saturday 14.10.2023 field trips: Brenner Base Tunnel / KW Tauernmoos

    Details to every single excursion are available below:

    Field trip Semmering base tunnel

    Construction of the Semmering base tunnel was started in 2012. The tunnel has a length of 27,3 kilometers and consists of two running tunnels. Excavation works are nearly finished and the concrete works for the inner lining where started in 2020. The base tunnel is part of the new 470 kilometer long railway line between Vienna and Villach which should be completed by the end of 2030.

    The tour begins with the presentation of the complete project and continues with a visit to the building lot SBT2.1 - tunnel Fröschnitzgraben.  You will see the impressive installations for the underground works which are supplied over two 400 meter deep shafts. After entering the tunnel system by one of the shafts you will be shown the running works on the two single line tunnels. The participants will be supplied with the necessary clothing and split up into groups for the visit.

    Field Trip Brenner Base Tunnel

    The Brenner base Tunnel (BBT) is a low gradient tunnel with a length of 55 km running between Innsbruck (Austria) and Fortezza (Italy) and therefore a cross border tunnel of European importance. The tunnel has two single bores by a diameter of 8.1 meters and a distance between the two running tunnels between 40 and 70 meters. Every 333 meters the two tunnels are connected by a cross passage. As a speciality this base tunnel has an exploratory tunnel over the full length.

    The site visit will beginn in the modern information center called „Tunnelwelten“ in Steinach am Brenner with a project presentation. After a short lunch break you tour will take you underground to see the emergency station St. Jodock and an assembly cavern for one of the TBM’s as well as the crossover tunnel. At the end you will be shown the large landfill
    area Padastertal.

    Field Trip Limberg III

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

    After a short project presentation you will visit the building site at an altitude of over 2000m.  The existing reservoirs at Moorboden and Wasserfallboden as well as the landfill site of Drossen will be on your tour before going underground to see all the different excavation sites. At the time of your visit you will mainly see the ongoing concrete works. At the end of your visit you will be invited to a meal in the site canteen before leaving for Salzburg.

    Field Trip Tauernmoos

    With the construction of the pump storage power plant Tauernmoos the ÖBB (Austrian federal Railway company) are adding a very important asset to their existing power plant at Tauernmoos for the production of electricity for the rail infrastructure.

    The two existing reservoirs Tauernmoossee and Weißsee with a difference in altitude of 220 m will be connected by an underground pressure shaft. The power plant will finally have a pump turbine capacity of 170 megawatts and an annual production of 460 GWh.

    The excursion will start with a visit to the existing power plants Uttendorf 1 & 2. After a half hour drive to the site office at Enzingerboden you will be offered a small snack and fitted with the needed tunnel gear to explore the underground works at an altitude of up to 2300 m. The highlight will be a visit to the large machine chamber, the pressure shaft and the inlet trumpet.

    Finally you will get the chance to enter the control tunnel underneath the existing concrete arch gravity dam Tauernmoos.

    Field trip SKW Kühtai

    TIWAG (the regional electricity supplier of the Tyrol) is constructing the hydro pump storage plant in Kühtai at an altitude of approximately 2000m. With an additional water intake from the Ötzvalley and the Stubaivalley the existing power plant will have a significant extra production.

    The technical facts are as follows:

    New Reservoir with a capacity of 31 million cubic meters
    Rock-fill dam with vertical earth core with a hight of 113 meters
    Adduction tunnel 25,5 km long with a diameter of 4,20 meters
    Additional annual production of 216 GWh
    Capacity 130 MW as turbine and 140 MW as pump

    During the excursion you will see all the works for the dam construction from winning the material in situ, the material treatment up to placement of the material. The tour will also take you underground to the concrete works in the two machine chambers and give you an insight to the installations of the whole site.
