Construction kicked off for Saint-Nazaire substation

Chantiers de l’Atlantique

The first steel sheet of the electrical substation for the Saint-Nazaire offshore wind farm was cut today (9 January 2020) at Chantiers de l’Atlantique shipyard in Saint-Nazaire, France.

The substation was ordered in August 2019 by Parc du Banc de Guérande, a company held jointly by EDF Renouvelables and Enbridge, Inc. The substation is scheduled to leave the shipyard in the summer of 2021 and to be connected with the wind farm in 2022. The substation will collect and transform the electricity produced by wind turbines and transfer it to the shore network, while ensuring  remote control of the wind farm.

Chantiers de l'Atlantique, with its partners GE Renewable Energy’s Grid Solutions business and SDI (DEME Offshore), have also been selected by Eoliennes Offshore des Hautes Falaises et Eoliennes Offshore du Calvados, a joint venture between by EDF Renouvelables, Enbridge Inc and wpd offshore, to design, manufacture and install the electrical substations for the
Fécamp and Courseulles-sur-Mer wind farms (Normandie, France).

The delivery of the Fécamp and of Courseulles-sur-Mer substations, with a total capacity of around 500 MW each, should take place respectively at the end of 2022 and in 2023. Over the period of execution of these three projects, more than 400 people will be employed in the Saint-Nazaire area.


Atlantique Offshore Energy is responsible for the topside and jacket-type foundation design, manufacturing and commissioning. GE Grid Solutions is in charge of high voltage electrical equipment and protection control systems design, manufacturing and commissioning. SDI has been tasked with the transport and installation of these structures, including offshore prepiling works.


"This choice allows to strengthen the French industrial sector of offshore wind power, which is facing a particularly competitive market dynamic,"
said Frédéric Grizaud, Director of Atlantique Offshore Energy. "After our first successes in Europe, we are proud to consolidate our industrial know-how on these three projects. This strategy gives us the needed visibility to address in parallel other projects being developed in France and worldwide."
