The scope of supply for ANDRITZ includes two variable-speed motor-generators, each with a rated output of 95 MVA, including auxiliary equipment. The variable-speed generators will be connected to the grid via full-size converters and enable efficient and optimized operation within the defined head variations. Speed control is used both for controlling output in pumping mode and for extending the operating range in turbine mode.

The Kühtai 2 pumped storage power plant is an extension of the existing Sellrain-Silz power plant group in the Längen Valley of the Tyrolean Stubai Alps and will be built completely underground in a cavern. Kühtai 2 and the new Kühtai reservoir will increase the generating capacity of the entire power plant group by 50%.

The power plant group serves as a sustainable energy storage facility to cover peak loads and thus contributes significantly towards stabilizing the power grids and increasing security of energy supply. Commissioning is scheduled for 2026.
