RTE and the Chantiers de l’Atlantique – Hitachi Energy consortium sign a €4.5 billion contract for the construction of three offshore direct current platforms and three onshore converter stations for the Normandy (Centre Manche 1 & 2) and Oléron Island offshore wind farms

Thursday May 2, 2024, in the presence of Bruno le Maire, Minister of the Economy, Finance and Industrial and Digital Sovereignty and Roland Lescure, Minister Delegate in charge of Industry and Energy, Xavier Piechaczyk, Chairman of the Management Board of RTE, Laurent Castaing, Managing Director of Chantiers de l'Atlantique and Niklas Persson, Managing Director of Hitachi Energy's Grid Integration business, have reached a historic agreement for the construction of the first offshore direct current platforms and onshore converter stations for the Normandy (Centre Manche 1 & 2) and Oléron Island offshore wind farms.

This contract, of an unprecedented scale for RTE, marks an acceleration in the development of offshore farms and positions France among the few European nations building large offshore high voltage direct current converter stations.

These platforms, with a higher power (1250 MW) and a larger size than the alternating current ones, equipping the first French offshore wind farms, underscore the scale up needed in the production of offshore renewable electricity.

The new generation of offshore wind farms is more powerful and located further away from the coast, taking advantage of stronger and more favorable winds. In order to connect these offshore farms to the onshore electricity grid, it is necessary to use direct current, a technology capable of transporting electricity over very long distances. In Normandy and Oléron, the high voltage direct current (HVDC) transmission systems by Chantiers de l'Atlantique and Hitachi Energy will enable the integration of more than 3.5 GW of renewable energy into the RTE network.

Following an international call for bids, RTE, the project owner of the connection of offshore wind farms, has selected the Chantiers de l'Atlantique and Hitachi Energy consortium to carry out the execution of offshore and onshore conversion stations for the future offshore wind farms in Normandy and Oléron.

With more than a dozen offshore platforms built for wind farms in France and throughout Europe, Chantiers de l'Atlantique is a leader in the manufacture, construction, integration and turnkey delivery of the largest maritime structures. 

Hitachi Energy's expertise in HVDC technology is recognized globally and has been selected for the IFA2 and Bay of Biscay interconnections, between Great Britain and France as well as Spain and France.

With a total amount of €4.5 billion euro, this contract highlights RTE's industrial strategy and supply policy, which will be at the core of its future strategic network plan for the next 15 years. It demonstrates RTE's capacity, through its investments in the national electricity transmission network, to support employment and value creation in France and Europe. Almost all of the economic benefits from the construction of these platforms will thus take place in Europe, including almost half in France, particularly within Chantiers de l'Atlantique, the largest shipyard in Europe.

For the construction of the three offshore platforms to be built in Saint-Nazaire, Chantiers de l'Atlantique will double its production capacity for electrical platforms, investing nearly €100 million in this expansion. Especially, it will acquire Europe's largest paint cell, with a total area of 4,600m², and capitalize on its state-of-the-art industrial facilities, including its slipway equipped with gantry cranes lifting up to 1,400 tons.

Together, the expertise of RTE and the Chantiers de l'Atlantique – Hitachi Energy consortium makes an essential contribution to offshore wind projects and the achievement of carbon neutrality in 2050.

About RTE

RTE, manager of the French electricity transmission network, carries out a public service mission: guaranteeing the supply of electricity at all times and with the same quality of service on the national territory thanks to the mobilization of its 9,500 employees. RTE manages electricity flows and the balance between production and consumption in real time. RTE maintains and develops the high and very high voltage network (from 63,000 to 400,000 volts) which includes nearly 100,000 kilometers of overhead lines, 7,000 kilometers of underground lines, 2,900 electrical substations in operation or co-operation and a fifty cross-border lines. The French network, which is the most extensive in Europe, has 37 interconnections with its neighboring countries. As a neutral and independent industrial operator of the energy transition, RTE optimizes and transforms its network to connect electricity production installations regardless of future energy choices. RTE, through its expertise and its reports, informs the choices of public authorities.
