The Styrian plant manufacturer Andritz AG is supplying two motor generators for the new Kühtai pumped storage power plant, which is being built by Tiroler Wasserkraft AG (Tiwag) and is scheduled to go into operation in 2026.
Generators for pump and turbine operation
The Kühtai 2 pumped storage power plant is an extension of the existing group of power plants in the Längental in the Tyrolean Stubai Alps and is being built completely underground in a rock cavern. Andritz is supplying two variable-speed motor generators and ancillary systems, as the group announced on Tuesday.
The speed control is used both for power control in pump mode and to expand the control range in turbine mode.
50 percent more generation capacity
The order volume is 425 million euros, the volume of the order to Andritz AG was not disclosed by the company. With Kühtai 2 and the planned new Kühtai reservoir, the generation output of the entire power plant group will increase by 50 percent, it is said.
Meanwhile, the new ÖBB Nightjet trains were presented in Vienna on Tuesday, for which Siemens Graz developed its own lightweight bogies – they are significantly quieter and less subject to wear. A total of 33 of these train sets were ordered from Siemens Mobility – more on this in the new Nightjet presented by ÖBB (wien.ORF.at).
