Based on V-164 technology by Vestas, each turbine will have a power output of 10 MV, equivalent to the energy used by nearly 17,000 inhabitants.
Each floating structure takes the form of a square semi-submersible steel barge.
- Optimized dimensions (45m x 45m x 17m) for easy integration in the port.
- Hull as a ring with a central opening (Damping pool©) to dampen swell movements.
- Bottom extended around the floating structure to dampen swell frequencies.
- Wind turbine attached to the back of the deck via a transition piece.
As the French transmission system operator, RTE is responsible for ensuring power systems operate safely and efficiently. As such, it operates, maintains and develops high and extra-high voltage lines across France and neighboring countries.
RTE will be responsible for connecting the Eolmed pilot wind farm to the electricity grid using a 33,000-volt submarine and underground link over approximately 27 km.
The underwater connection will run from the wind farm to the beach at Port-La-Nouvelle, crossing the commercial port’s shipping channel and bypassing the 30-metre beacon to the south. The junction chamber between the submarine and underground link will be located in one of the parking lots by the beach.
The underground connection will first run through the south of Port-La-Nouvelle, before branching off at Avenue du Général-de-Gaulle. The cables will then cross under the railway line, before arriving at Combe de Buis and the Port-La-Nouvelle electrical substation.
Connecting the submarine and underground cables
The landfall is the point at which the offshore cables reach the shore. The junction chamber will be built in a concrete structure buried at a depth of around 2 m.
This connection consists of a single tri-cable with a protective sheath. Depending on the seabed, and to ensure the safety of the structure, it will be buried in the marine sediment.
From the landing junction chamber, the underground connection comprises 3 separate sheathed cables, each around 7 cm in diameter, buried in an underground trench at a depth of around 1.5 m.
