Description
Fondation OPEN-C coordinates, develops, and manages France’s five offshore testing sites for floating wind and Marine Renewable Energies (MRE), providing infrastructures dedicated to industrial development, research, and innovation under real-world conditions. Offshore testing validates tomorrow’s energy solutions and accelerates their deployment, while measuring performance and environmental impact. As a public-interest organization, the Foundation is an essential tool to mitigate risks, reduce costs, and accelerate the time-to-market of offshore innovations. Building on the combined strength of its teams and sites, Fondation OPEN-C serves as a strategic lever to advance the energy transition at sea, supporting the development of Offshore Renewable Energies (ORE) in France and across Europe.
