September
The offshore electrical substation
The substation will be positioned in the centre of the Saint-Brieuc wind farm on a jacket foundation. It will house all of the wind farm's automated control systems, as well as all of the equipment required to ensure a reliable electrical link between the wind turbines and the onshore grid.
A key element of an offshore wind farm
The Saint-Brieuc substation will play a central role, collecting the electricity produced by the 62 wind turbines and raising the voltage, via power transformers, to limit energy losses when transferring electricity to the coast. In the offshore substation, the current is thus increased from 66,000 to 225,000 volts.
"We look forward to working alongside Ailes Marines to provide clean energy in France, thanks to our state-of-the-art substation technology and our expertise in integrating renewable energy into the terrestrial power grid. »
"This new partnership with GE Grid Solutions, concerning the electrical equipment for the substation of the Saint Brieuc offshore wind farm, will help to maintain skilled jobs in France. The green economy is a major source of industrialization and the creation of sustainable, high-quality jobs capable of stimulating activity at all stages of the value chain. After making good progress on the latest supply contracts, the project is moving into the construction phase with the support of all stakeholders as France accelerates its transition to a decarbonised economy. »
