EDF has awarded Alstom two contracts to renovate the speed and voltage systems in hydroelectric power plants in France.

The deals, awarded following a call for tenders in February 2013, are part of a significant investment scheme launched by EDF’s Production and Hydraulic Engineering Division, which primarily involves modernising electrical control installations in hydroelectric power plants.

The operation involves replacing existing systems with Alstom-designed ones to control the hydraulic turbines and their related generators. In addition, the contracts include a MOC (Maintenance in Operational Conditions) section, thus further asserting Alstom’s positioning in high value-added services. Initial refurbishment works are due to start in early 2015.

Alstom Hydro Services will carry out speed control work and Alstom Power Automation & Controls will be responsible for voltage control.

"By winning this substantial market, Alstom is reasserting its leading position in the renovation of hydroelectric power plants and in related services aiming at maintaining them in operational condition," said François Taveau, EDF Group Key Account Director for Alstom Power. "The Group has built a sound experience in the assessment, maintenance and refurbishment of power plants, and this contract will strengthen our positioning within the hydroelectric power plant market and that of rotary machine control systems in all types of power plants."
