The fair



The French Alps are Europe’s primary hydroelectric hub. They contain an unparalleled density of installations, as well as all the knowledge and companies required for commanding this energy of the future. It is one of the rare industrial sectors in which France remains fully independent.

Hosted by Hydro 21, this ecosystem now includes over 100 members from four major key sectors (engineering, research & development, manufacturing and operation) to design, implement and master future hydroelectric technologies – particularly those that can answer electrical grid flexibility needs, including:

• the engineering of major installations, civil engineering works and technical-economic approaches,

• manufacturers and integrators of hydraulic, electrical and mechanical machinery,

• operators of hydroelectric installations, energy systems, as well as information and control-command systems.
