Ministère de l'Ecologie, du Développement durable et de l'Energie (MEDDE) is undertaking the Saint-Brieuc Offshore Wind Farm 496 MW project 17km off the coast of Saint-Brieuc, in France.

The project involves the construction of an offshore on a 77km2 area with a capacity of 496MW housing 62 Adwen AD8-180 type wind turbines of 8MW capacity each. It also includes the construction of an offshore substation and turbine foundations and the installation of turbines, transformers, subsea transmission cables and other related facilities.

In July 2011, MEDDE launched the tender for the developer contract.

In April 2012, Ailes Marines SAS, formed by Iberdrola Renovables France (70%), Eole-RES (22.5%) and Caisse des Depots et Consignations (7.5%) was awarded the developer contract.

IN VIVO Environnement and Neoen S.A.S were appointed as an environmental study consultant. NIRAS A/S, Intertek Energy & Water consultancy services, Ifremer and DHI Group were appointed as a study consultant.

In July 2014, Areva, in a joint venture with Gamesa, was confirmed as the project's turbine manufacturer that will supply 62 turbines with an individual capacity of 8MW each. In 2012, 100 turbines of 5MW capacity were planned for the project, but the increased turbine power impacted the reduction in the number of turbines to be installed. Areva is also responsible for the installation of jacket foundations.

In March 2015 Adwen a jointly owned company was created by Areva (50%) and Gamesa (50%). Adwen is responsible for the design, manufacture, installation and maintenance of the wind turbines. Ceole is also responsible for the manufacturing of turbine towers.

The turbines will be installed upon completion of the validation process by the Ministry of the Ecology and Sustainable Development (MEDDE).

In June 2015, the Ministry of Environment validated the new plan of using 8MW machines instead of 5MW machines initially planned.

A public inquiry process has been held in August 2016 - September 2016.

In January 2017, The project received a favorable opinion from the public inquiry.

In April 2017, Ailes Marines, the developer and future operator of the 496MW offshore wind farm project in the Bay of Saint-Brieuc, France, has received the three administrative authorizations (The company has obtained the concession of utilisation of the maritime public domain; the Unique Authorization for the installations Structures, Works and Activities (AU IOTA); and the work Project Authorization (APO))required to construct and operate the wind farm.

The project is in the process of filing Final Investment Decision, which will be followed by the launch of various tenders for the installation and manufacturing of jacket type foundations in 2018.

Planning activities are underway. The construction is expected to start in 2019 and the wind farm is scheduled to be operational in 2021.
