ABB will provide Reliable generator circuit breakers (GCBs), the Isolated Phase Busduct (IPB), and the transformers help to ensure that the plant is operated efficiently.
Nant de Drance, the operator of the plant, is planning to invest around $2.2bn in the erection and installation of the power plant, along with its partners Alpiq, SBB, Industrial Works and the Valais Electricity Company FMV.
The pumped-storage power plant is expected to produce about 2,500 million kWh of electricity per year while the six sets of 150MW pump turbines will produce a total capacity of 900MW.
Capable of storing excess energy in the form of water, the plant uses the difference provided by the 425m vertical shafts between the two reservoirs to generate power.
