France's second offshore wind farm produces its first green megawatt-hours in Brittany

The first green electrons produced by the Saint-Brieuc offshore wind farm have been fed into the national grid by its operator, RTE. This is the second French offshore wind farm to produce green megawatt-hours.

Following the test phase, the wind turbines were put into production on July 05 from the Ailes Marines marine coordination center in Kerantour (Côtes d'Armor).

The park's output will increase as the 62 wind turbines are installed and commissioned.

"It is with great satisfaction that we have launched the production of the first wind turbines of the wind farm. A milestone symbolizing 12 years of effort to bring this gigantic project to fruition, which contributes both to Brittany's energy sovereignty and to the energy transition, a key element in the battle against climate change," says Emmanuel Rollin, Managing Director of Iberdrola France.

The electricity generated is collected by the offshore substation at the center of the wind farm. It is routed via two 225 kV undersea export cables installed by RTE (Réseau de Transport d'Électricité) to Caroual beach in Erquy. The electricity is fed into the grid via the Doberie substation in Hénansal (Côtes-d'Armor).

The park will generate around 1,820 GWh/year, equivalent to the annual electricity consumption of 835,000 inhabitants (including heating), or 9% of Brittany's total electricity consumption.

In fact, once fully commissioned, the Côtes-d'Armor region (population 600,000) will become a positive-energy department, producing more energy than it consumes on its domestic side.

The Saint-Brieuc offshore wind farm will reduce Brittany's energy dependency while contributing to the objectives of the French Multiannual Energy Program (PPE).
