Seeking to capture the tremendous potential of marine winds, ENGIE is investing in major offshore wind projects, both bottom-fixed and floating. The Group actively participates in the emergence of a sustainable industrial sector through its Ocean Winds 50/50 joint venture with EDPR.
What is offshore wind energy?
An ocean wind turbine, usually called an offshore wind turbine, uses the power of marine winds to produce renewable, carbon-free energy. It works in the same way as a land-based wind turbine but can be installed in two ways: on a foundation anchored to the seabed (a so-called "bottom-fixed" foundation) or on a floating foundation simply connected to the seabed by anchor lines. With higher masts than those of onshore wind turbines, offshore wind turbines benefit from greater and more regular wind power and can therefore produce up to twice as much energy as onshore turbines.
According to various scenarios, offshore wind energy could account for up to 11.3% of power generated in Europe by 2030. Today, Europe has 25 GW of installed offshore wind capacity and the European Union has set its sights on 300 GW by 2050. The growth potential of the sector is considerable in view of the extent of Europe's coastlines.
Ocean Winds, ENGIE’s JV for offshore wind energy activities
In January 2020, ENGIE and the Portuguese group EDPR created a new 50-50 joint venture, Ocean Winds, to speed up their development in offshore wind energy. Through this joint venture, ENGIE and EDPR are combining their offshore wind assets, know-how, and project pipeline. Since its creation, Ocean Winds has expanded sharply and in Q1 2022 reached a projet capacity of 11.2 GW across the world.

- In France: projects off the coasts of Le Tréport, Yeu and Noirmoutier islands
With for example, projects off the coasts of Dieppe-Le Tréport and the Yeu and Noirmoutier islands, ENGIE is contributing to the development of a sustainable offshore wind energy industry in France. The consortium consisting of ENGIE, EDP Renewables and Caisse des Dépôts has been selected by the French government to develop and install two offshore wind farms with a total capacity of approximately 1,000 MW. The estimated capacity of these wind farms should produce the equivalent of the energy consumption of 1.5 million inhabitants. Each of these state-of-the-art wind farms will be equipped with 62 8-megawatt wind turbines manufactured by Siemens Gamesa Renewable Energy. ENGIE and its partners are carrying out these projects in close consultation with local stakeholders. To find out more and receive regular information on these projects, visit the websites of the Dieppe and Le Tréport project and the Yeu and Noirmoutier islands project.
The SeaMade wind farm entered into service in Belgium in 2020. It comprises 58 wind turbines and offers a total capacity of 487 MW. The site produces enough electricity to cover the annual consumption of 485,000 Belgian households while reducing CO2 emissions by 600,000 tonnes each year.
