Limberg 3 pumped storage power plant
The Kaprun upper stage/Limberg 3 pumped storage power plant is located in the municipality of Kaprun in the province of Salzburg and forms part of a large generation group of storage reservoirs and power plants.
For this purpose, a third transformer and power plant cavern will be built into the mountain next to the existing power plants of the "Kaprun Upper Stage" (Limberg 1 and 2) and will be connected to the existing reservoirs Mooserboden and Wasserfallboden with a headrace tunnel.

The Limberg III power plant project was approved in 2017. It is a pumped storage power plant with a capacity of 480 megawatts in Kaprun. Like Limberg II, which was commissioned in 2011, it will be built completely underground between the two existing reservoirs Mooserboden (storage target 2,036 m) and Wasserfallboden (storage target 1,672 m).
It is also planned to raise the level of the Wasserfallboden reservoir by 8 meters. The increase in the Limberg dam that is necessary can be realized by using existing construction reserves while maintaining unrestricted dam safety. The necessary approval documents will be submitted to the responsible authorities in the next few weeks.
