The operation involved installing two 225 kV High-Voltage Alternating Current (HVAC) export cables to connect the wind farm’s offshore substation to the French electricity grid. Over 100 professionals and two primary vessels, including Nexans’ specialized cable-laying vessel, Nexans Skagerrak, were deployed to complete the task. The commissioning of the export cable system is scheduled for spring 2026, marking a key milestone in the project’s timeline.
Under a contract signed in March 2022 with Réseau de Transport d’Electricité (RTE), France’s transmission system operator, Nexans handled the design, engineering, manufacturing, installation, and protection of the 225 kV cables. The company will also provide ongoing inspection, maintenance, and repair services to ensure the wind farm’s long-term operational reliability.
In July 2025, the offshore substation, designed and constructed by Atlantique Offshore Energy, a division of Chantiers de l’Atlantique focused on marine energy, was installed by DEME’s Gulliver vessel. The substation serves as a critical link for transmitting power to the mainland. Foundation work is progressing, with the first jacket foundation installed earlier in September 2025. The wind farm will consist of 62 Siemens Gamesa 8 MW turbines, contributing significantly to clean energy production.
“The completion of the export cable campaign is a pivotal step in advancing France’s renewable energy goals,” a Nexans spokesperson noted. The project is expected to bolster sustainable energy infrastructure while supporting economic growth through job creation and technological innovation in the region.
