Voith is to supply two Pelton 60 MW turbines and a 60 MW storage pump for the Ritom pumped storage power plant in Switzerland.The plant, which has been in operation since 1920, is being replaced by a new CHF250 million facility.
The Ritom pumped storage power plant’s four Pelton turbines, with a total rated output of 44 MW, will be replaced by much more powerful generating units in the new facility. Voith will be responsible for the design, fabrication, installation and commissioning of the two Pelton 60 MW turbines and the 60 MW storage pump.
The first machine unit will supply power for the 16.7 Hz Swiss Rail network and the operation of its trains. The second will feed the electricity it generates into the 50 Hz public grid. The third unit, a 60 MW capacity storage pump with a delivery head of more than 700 m, will pump the water for reservoir management and to provide balancing power (operating reserve) from the Airolo basin to Lake Ritom.
