The companies agree to jointly make wind turbine and foundation offers on major European projects. AREVA will bring its expertise in design and production of wind turbines and STX France its know-how in specialized offshore foundations, with a view to strengthen competitiveness of offshore wind power in a European market that should see its installed base reach around 40,000 MW by 2020. STX France would, in addition to designing the foundations, be responsible for complete or partial manufacture of the structures. Almost one third of investment expenditure in offshore wind farms is generated by the manufacturing, logistics and installation costs associated with the foundations and turbine towers. Their optimization is therefore a major lever for reducing overall project costs.
