In the past, pump and turbine runner repair work (Francis, Pelton, Kaplan) was exclusively performed through welding and grinding with profile models acting as the only reference points for the original hydraulic profiles. Our centralised machine shop now offers 3D scanning which allows the modelling of any component.
HYDRO Exploitation specialises in the area of fitness-for-service and risk analysis thanks to its experts in the fields of civil, mechanical and electrical engineering.
On 22 December 2015, the Romande Energie-owned Centrale des Farettes’ first hydroelectric production facility entered into its test run phase following the successful completion of installation works lasting several weeks. Our Automation & Control unit was actively involved in analysing and installing a control system for this 11 MW-capacity machine.
