From 2024, offshore work will commence with the installation of the piles. France’s RTE (Réseau de Transport d’Electricité), responsible for the wind farm’s connection, will set up a double subsea connection to transfer the electricity generated at sea to the onshore grid.

The installation of the jackets and the offshore substation built by Chantiers de’l Atlantique in Saint-Nazaire will follow in 2025.

DEME will be responsible for the transport and installation of the foundations, the substation, and the construction, transport, and installation of the inter-array cables in 2026.

The wind turbines, produced by Siemens Gamesa in its Le Havre facility, will be installed by Jan de Nul Group during that same year.
