Substation for theWind Farm off the Coastof Calvados
In February 2021, Atlantique Offshore Energy, along with its partners GE Grid Solution and SDI, a member of the DEME Group, received an order from the consortium of companies led by EDF Renouvelables in association with Enbridge and wpd Offshore, to design and manufacture the electrical substation for the Calvados offshore wind farm located off the coasts of Courseulles-sur-mer.
This project counts 64 offshore wind turbines for a cumulated power of nearly 450 MWThe considered solution will allow to produce enough energy to provide for more than 630,000 people, that is to say 90 % of the region inhabitants, by 2024.
Organization of the contract:
The consortium gathers the expertize of Atlantique Offshore Energy – in charge of the designing, manufacturing and commissioning of the topside and the Jacket structure – of GE Grid Solution – in charge of the designing, manufacturing and commissioning of the high-voltage electrical equipment as well as the safety and the control and command equipment – and of SDI – in charge of the transportation and installation of the structures. Before that, the consortium won the call for bidders regarding the substation for the Saint-Nazaire and Fécamp offshore wind farm. The substation for the Calvados offshore wind farm is mostly identical to the previous ones. The experience gained on the two previous substations will thus allow to further optimize the maintenance and exploitation capabilities of the client’s upcoming wind farms.
This contract brings to four the number of electrical substations on Chantiers de l’Atlantique’s book of orders.
