Construction, asbestos removal, photovoltaics, energy storage, import-export, real estate — a family-owned group from Auvergne that masters the whole chain, from the roof being rebuilt to the energy being managed.
The group
In 2016, after more than thirty years at EDF, Jean Renard founded JR Énergie Conseil in Cournon-d'Auvergne. He now chairs the group as head of JR Holding, guardian of its strategic vision and of the balanced development of each company.
An entrepreneurial vision built on high standards, technical mastery and a constant pursuit of excellence — carried by in-house teams that design, remove asbestos, build, install, connect and operate, seamlessly.
