Launched in 2011, the Romanche-Gavet work site, near Grenoble, is the largest development project in France. On a technical level, EDF's two hydroelectric engineering units are involved in the entire production chain, both upstream (feasibility studies, construction, rehabilitation, etc .) and downstream (operation, monitoring of hydro-meteorological forecasts, etc .) . On an environmental level, EDF specialists provide expertise in hydrology, sedimentology, the conservation of rivers, and aquatic biology.
