Successful Sail-Away and Installation of GE’s Electrical Substation for France’s Saint Nazaire Offshore Wind Farm

Significant milestone reached! 

The very first electrical offshore substation (OSS) in France has triumphantly sailed off on August 18th and was installed on its jacket 12 km from the coast. It’s impressive to see the extent of this electrical substation – Its cumulative weight is roughly equal to the London Eye, (also known as the London Millennium Wheel), or about 280 adult African elephants!!!

GE Renewable Energy’s Grid Solutions’ AC Systems department, responsible for turnkey projects at its site in St. Priest (France), designed and integrated the high and medium voltage systems for this project. The systems include five 220 kV gas-insulated switchgear (GIS) from Aix-les-Bains (France), two 220/33 kV transformers made in Monchengladbach (Germany), two SCADA systems developed in Montpellier (France) as well as one 33 kV GIS and a telecommunications system.

When it comes to the consortium partners’ pursuits: DEME Offshore provided the transport and installation of the OSS, including the offshore pre-piling works. Chantiers de l’Atlantique is responsible for the topside and jacket foundation design, manufacturing, and commissioning. GE Renewable Energy’s Grid Solutions is responsible for the high voltage electrical supplies and protection control systems design, manufacturing, and commissioning.

The electrical substation for Saint Nazaire’s offshore wind farm will be attached to 80 Haliade 150 6 MW offshore wind turbines produced by GE Renewable Energy.

“With this major milestone delivered to our customer, GE’s Grid Solutions demonstrates once again its domain expertise to integrate turnkey high voltage electrical systems for the Alternating Current (A/C) offshore market. Moreover, GE reaffirms its position as a leading provider of solutions for this sector, with a dedicated focus on the development of turnkey solutions in Europe and worldwide for our valued customers” stated Johan Bindele, AC Systems Business Leader at GE’s Grid Solutions. 

The Pacific Power Reps Team is proud to be representing GE Grid Solutions, and proud of the team of engineers behind the scenes always innovating and never satisfied.

Additional Information about Parc Eolien en mer de St Nazaire:

The Parc Eolien en mer de St Nazaire is the first offshore windfarm France. It will have a capacity of 480 MW, with the ability to power 20% of the Department Loire Atlantique. This project is a key milestone based on France’s energy roadmap, targeting 32% renewables within its total energy expenditure. The Parc Eolien en mer de St Nazaire design is scheduled to be operational by the end of 2022.

This project was granted in 2019 to a consortium including Atlantique Offshore Energy, the business section of Chantiers de l’Atlantique committed to Renewable Marine Energies, DEME Group’s French subsidiary SDI, Chantiers de l’Atlantique, and GE Renewable Energy’s Grid Solutions. The 480 MW Saint-Nazaire offshore wind project is being produced by EDF Renouvelables and EIH S.à r.l, an indirect subsidiary of Enbridge Inc., and CPP Investments.
