Réseau de Transport d'Électricité (RTE France) has issued a tender for project management and technical support for the installation and protection of connection cables for three offshore wind farms. The three projects concerned are the Saint-Brieuc, Dieppe-Le Tréport and Iles d’Yeu et de Noirmoutier offshore wind farms.

The tender is divided into two lots with the first lot covering monitoring and validation of detailed studies related to the installation and protection of submarine cables. This includes marine surveys (UXO, geotechnical) and the definition of procedures. It also covers the monitoring and control of installation of cable and cable protection at sea as well as cable landing and cable pull-in operations.

Lot 2 includes the supporting RTE with follow-up and validation of the detailed studies related to the civil works at the cable landings. This includes maritime and coastal environments as well as a cliff for one of the landings. The scope also covers monitoring and control of civil works at the landing sites.

RTE is the electricity transmission system operator of France. It is responsible for the operation, maintenance and development of the French high-voltage transmission system. It is also responsible for the connection of offshore wind farms to the French national grid for integration and distribution.


The three offshore wind farms each have a maximum capacity of 500MW. In June 2018 French President Emmanuel Macron granted approval for the projects to move forward with a tariff on €150/MWh. Until then, the projects were deemed too expensive for approval given they had tariffs of €200/MWh.

The
Bay of Saint-Brieuc project has a total area of 75km2, and will have a total capacity of 496 MW. Siemens Gamesa has been lined up to supply 62 of its 8 MW direct drive turbines for the project. It is owned by Ibedrola, eole RES and Caisse des dépôts et consignations.

The
Dieppe-Le Tréport and Iles d’Yeu et de Noirmoutier offshore wind farms are both owned by a consortium of Engie, EDP Renewables and Caisse des dépôts et consignations. They will also have a maximum capacity of 500 MW each and will feature Siemens Gamesa 8 MW direct drive turbines.
