Replacement of drainage circuits on the Cheylas power plant
Contract holder for the replacement of piping
EDF power plant at Cheylas (Dpt 38)
Project in progress
Each of the two reversible 240 mw generators are installed at the bottom of a shaft 20 m in diameter and 66 m deep. These pump turbine generators are the most powerful in France and can raise the water from the Cheylas basin to the Flumet basin or turbine it in the opposite direction. The drainage circuits prevent any flooding in the station, particularly when the generators are activated.
Replacement of piping circuits in difficult access conditions in partnership with a company of rope access technicians.
Measuring and support modifications to optimise erection time on site.
