Ailes marines (Iberdrola) is still awaiting the judgment of the French Council of State concerning final appeals submitted against the 496 MW Saint-Brieuc wind farm, located 16.3 km off Brittany.

The appeal concerns the technical modification of the park on the change of 8 MW Adwen wind turbine to 8 MW Siemens Gamesa which requires amending the Decree of IOTAs (works, works and activities subject to the water law).

This is the final appeal blocking the project from entering construction; the majority were cleared in 2019. Ailes Marines is hoping for a decision from the French Council of State by the end of the year.

Despite the lingering appeal, the project did achieved financial close earlier this year and all tier one contracts have been awarded for construction to start next year.

The wind farm will feature 62 SG 8.0-167 DD turbines with jacket foundations supplied by Navantia-Windar, in Fene (A Coruña) and Avilés (Asturias), respectively.

Prysmian will install and commission 90 km of 66 kV alternating current high.voltage connection cabling and three XLPE insulation hubs.The cable hubs will be manufactured at the group's centres of excellence in Montereau-Fault-Yonne and Gron (France) and will be assembled and finished in Nordenham (Germany).

The substation has been awarded to the joint venture made up of Eiffage Métal and Engie Solutions. The substation is made up of a jacket foundation — measuring 63 m high and weighing 1,630 tons — and a topside measuring 55 m long, 31 m wide and 23 m high, with a total weight of approximately 3,400 tons.

Iberdrola has chosen GE Renewable Energy Grid Solutions to supply and install the main electrical equipment for the offshore substation

Van Oord will start the offshore operations in 2021 with the installation of the pin piles and the offshore substation using its offshore installation vessel Aeolus. The Aeolus will be assisted by a second vessel in 2022.

With an investment of EUR 2.4 billion, it is estimated that, once commercialisation begins in 2023, it will meet the energy needs of 835,000 people.
