Christophe Nicolet graduated in Mechanical Engineering from EPFL in 2001 and obtained his PhD degree in 2007 at the EPFL Laboratory for Hydraulic Machines in the field of hydroelectric transients modeling. Since 2007, Christophe Nicolet is director of Hydropower Dynamics Engineering SA, HDE, in St-Sulpice, Switzerland and also external lecturer at Ecole Polytechnique Fédérale de Lausanne, EPFL, in the field of «Hydroacoustic for Hydropower plants» at Master Degree. With HDE he provides consulting and expertise in the fields of hydraulic and electric transient analysis, power plant system stability, control system optimization, ancillary services capability optimization. With more than 25 years of experience in the field of hydraulic machinery and transients, he was involved in more than 20 Pumped Storage projects ranging from feasibility study to troubleshooting in Switzerland and abroad. He is also working group member of IEC-TC4 on hydraulic turbines of WG33 on pressure fluctuations and convenor of WG36 on hydraulic transients calculation.
