VALOREM Group governance

Jean-Yves GRANDIDIER – Founder and President

Jean-Yves GRANDIDIER’S passion for defending renewable energies began in his childhood. He called the oil crisis in 1973 shocking. Seeing my father forced to buy jerricans of petrol from American surplus stores, I would wonder why we were so dependent on a resource that came from the other side of the world”. That was what formed his pioneering spirit and convinced him that it was not up to energy resources to come to him, but up to him to look for new ones. In 1994, after a stint in the aerospace sector, he founded VALOREM. Given his deep involvement His involvement in the sector meant that Jean-Yves GRANDIDIER was able to call upon the public authorities to put in place a suitable regulatory framework for wind energy development: in 1996, he co-founded France Wind Energy, an organisation representing the profession. Today, his wind engineering office has become a green energy operator mastering every step of a renewable energy project.
