Alstom picks two French cities for 6-MW wind turbine manufacture

Plants in Saint-Nazaire and Cherbourg will be built to manufacture 6-MW wind turbines for offshore use; LM Wind Power will build 73.5m blades in Cherbourg.

Wind turbine manufacturer Alstom (Levallois-Perret, France) announced on Nov. 4 that it is planning to establish up to two sites dedicated to the production of components and to the assembly of 6-MW offshore wind turbines in the port areas of Saint-Nazaire and Cherbourg, France.

These two French sites would be for Alstom the first in the world entirely dedicated to offshore wind energy. The dimensioning of the project will depend on the success in the call for tenders of the consortium led by EDF EN to which Alstom belongs. Alstom’s investments could reach €100 million and generate up to 1,000 direct jobs and 4,000 indirect jobs.

If the consortium is selected at a level that ensures an industrial critical mass, Alstom plans to establish:

  • In Saint-Nazaire, the nacelles and generators manufacturing activities, to which would be added, still in Loire-Atlantique, Alstom’s offshore engineering centre.
  • In Cherbourg, the production of the blades, in partnership with LM Wind Power, as well as the towers manufacturing workshop, which would be set up by Alstom’s supplier, chosen subsequently.

“By locating in Saint-Nazaire and Cherbourg, Alstom would be sharing in the ambition of the consortium led by EDF EN and to which it belongs to create in France with its suppliers a long-lasting industrial and technological sector. We will be pleased to participate thus in regional planning through substantial investments and significant job creation, which are dependent of course on the success of our consortium, in this first call for tenders. The consortium will announce later the other investments planned as well as their localisation, for example assembly and service facilities.” stresses Jérôme Pécresse, president of the Alstom Renewable Power Sector.

These industrial projects will allow the production of the Haliade 150, the first new generation 6-MW offshore wind turbine, each unit of which will be capable of supplying the equivalent of approximately 5,000 homes with power. Alstom has relied on long experience to design this robust, simple and efficient offshore wind turbine. Its 73.50m/241-ft blades will be the longest in the world and it will be equipped with a permanent magnet generator. This advanced technology is capable of facing up to the severe constraints of the maritime environment and ensuring a reliability as well as an efficiency that are sufficiently high to reduce the cost of the electricity generated.
