Who are we?
In our central workshops we bring together on a single site the services of wheel repair, mechanical component overhaul and machining services, Our customers benefit from the collaborations resulting from this.
The HYDRO Exploitation machine shop in Martigny constructs various mechanical parts for mechanical reconditioning or for spare parts. It is also required to supply any necessary parts for refitting during operations.
EDF: rehabilitation of the Francis groups
As part of the programme to maintain and optimise its hydropower plants, Électricité de France (EDF) entrusted us in 2017 with the rehabilitation of the Francis groups at the St Pierre en Faucigny and Le Carrelet power plants.
Electricité de la Lienne: replacement of the group electrical protections
Energie Sion-Région SA (ESR), which operates the hydropower facility at La Lienne, chose us to replace the old electrical generator protections of the ABB REG216 type, that had been brought into service in the nineties, by new ABB REG670 units.
