From March to October 2016, our engineers Yvan Michellod and Robin Lauzière, supported by their teams and GEH Riviera-Chablais, commissioned two new pumped storage units (each with an output of 120 MW). A key stage in the completion of this project that began almost 10 years ago.
Our experts in non-destructive testing (NDT) can intervene on an installation in the event of an outage or during maintenance. They can thus inspect all the critical elements without damaging them, using a combination of methods that characterise the condition of the structural integrity or components, whereby reliable operation is key.
Services Industriels de Bagnes (SIB) have commissioned us to improve the availability of their seven turbine installations, with an output ranging from 100 kW for the smallest installation up to 2 MW for the largest, and two pumping stations.
