The operation
of an offshore wind farm

Wind is an inexhaustible resource whose intensity varies from place to place. The identification of sites well exposed to the wind is therefore an essential prerequisite for any wind farm installation. Wind turbines are designed to adapt to the physical constraints of a site and to the wind speed.

Everything starts with the wind that turns the blades

Wind turbines transform wind energy into electrical energy. The wind turns the rotor, composed of the blades and the hub. It is constantly oriented to face the wind. 

The blades drive a generator

Thanks to the more constant marine winds, offshore wind turbines have a higher efficiency than onshore wind turbines, the generator allows to produce electricity.

Electricity travels through a network of submarine cables

The wind turbines are connected by a network of cables to the electrical substation, which transforms the electricity produced into 66 kV and injects it into the 225 kV terrestrial network.

Electricity reaches the terrestrial network

It is routed via an underwater evacuation cable to a landing junction and then to the electrical substation, before being fed into your home.
