Iberdrola-owned Ailes Marines has selected GE Renewable Energy’s Grid Solutions business to provide the main electrical equipment for the Saint-Brieuc offshore wind farm’s substation in the northwest of France.
GE’s Grid Solutions will be in charge of the design, manufacturing, installation and commissioning of the high-voltage electrical equipment as well as the substation’s control and protection system.
GE’s Grid Solutions will design and manufacture 72.5kV and 225kV gas insulated switchgear (GIS) at its French plant in Aix-les-Bains.
The substation’s control and protection system will be designed at its centre of excellence in Montpellier, France.
Power transformers will be manufactured at its Gebze plant in Turkey.
GE’s Grid Solutions forecasts that the electrical substation’s commissioning tests will take place during 2022.
The offshore substation will be positioned at the centre of the Saint-Brieuc wind farm, on a jacket type foundation.
It will house the wind farm’s fully automated control systems, as well as all the equipment to ensure the reliable electrical connection between the wind turbines and the power grid on land.
The Saint-Brieuc substation will play a central role, by collecting the electricity produced by the 62 wind turbines and by increasing voltage, through power transformers, to limit energy losses when the energy gets transferred to the coast.
Within the offshore substation, voltage is elevated from 66,000 to 225,000 volts.
GE Renewable Energy vice president and CEO of grid solutions Heiner Markhoff said: “We look forward to working with Ailes Marines to bring clean energy to France with our advanced substation technology, as well as our expertise in integrating renewable energy to the grid.”
Ailes Marines president and Iberdrola’s international offshore business director Javier Garcia Perez said: “This new partnership with GE’s Grid Solutions for the electrical fitting of Saint-Brieuc’s offshore substation will contribute to maintain skilled jobs in France.
“The green economy is a major source of industrialization and sustainable, quality jobs which stimulate activity throughout the entire value chain.
“With the last of the supply contracts coming along, the project is progressing toward its construction phase, thanks to the support of all stakeholders, while helping France to accelerate towards a fully decarbonized economy.”
