AbstractConstruction of the Verbund project Limberg III pumped storage power station is currently underway in the area of the Kaprun/Salzach power station group. Preliminary work started on 6 April 2021, the main construction work started on 7 January 2022 and the overall facility is scheduled to be commissioned the end of 2025. Kaprun has a long history in the construction of power stations. The Kaprun storage power stations in the 1950s were an outstanding engineering feat and is symbolic of the reconstruction efforts that took place in Austria in the wake of World War II. The power station facilities at the main and upper stage have been in existence since the 1950s and have since been continuously expanded. From 2006 to 2011 the all‐year‐round reservoirs Mooserboden and Wasserfallboden were extended to include the Limberg II pumped storage station. The group is currently expanding the Kaprun/Salzach power station group by building the Limberg III pumped storage station, for which the same design as Limberg II has been adopted for implementation purposes. In addition to the significant logistical challenges posed by the high mountain location of the construction site, this report also covers the tunnelling systems.
