Wind generation in Haliade ™ 150 sea – 6 MW Alstom installed off the coast of Ostend on the site Belwind Belgium, produced its first kWh on 19 September.
According to Alstom, assembly and testing have optimized the procedures for installation and commissioning of the wind at sea. They will continue to confirm the behavior of the machine in a marine environment and refine procedures for operation and maintenance. The Haliade should receive final certification in the last quarter of 2014.
With a 150 meter rotor (blades with 73.50 meters), the Haliade 150-6 MW has a yield of 15% higher than existing offshore wind turbines, thus allowing it to supply power to the equivalent approximately 5,000 homes.
The turbine operates without gearbox (direct drive) with a permanent magnet alternator. Thus, the number of mechanical parts inside of the machine is reduced, which makes it more reliable and allows, at the same time, reduce operating costs and maintenance. Finally, Haliade 150 is equipped with Alstom Pure Torque® technology that optimizes its performance in protecting the alternator through a deferral of unwanted mechanical wind forces to the mast of the turbine.
The Haliade will be made entirely in France, the new plant generators and nacelles of wind turbines located in the port of Saint-Nazaire. During the summer, Alstom has transferred 150 tons of tools and wind turbines in production of temporary workshop to the new plant, which will be fully operational in early 2015. Eventually, the production of Haliade should generate 1,000 jobs direct and indirect jobs in France 4000.
To date, Alstom is the exclusive provider of 238 wind turbines Haliade 150-6 MW commissioned by the consortium led by EDF-EN, under the first call for tenders launched by the French government in 2012. Alstom also sold 5 Haliade for the field of Block Island in the United States.
“This project with Belwind confirms our technology leadership and our ability to innovate. The installation of our robust and efficient turbine will improve the competitiveness of offshore wind,” said Yves Rannou, Senior Vice President of Alstom Wind activity.
