Designed for the most challenging conditions

With one of the world’s largest offshore wind turbines, the Haliade* 150-6MW

Haliade* 150-6MW Offshore Wind Turbine

Thanks to its 150-meter diameter rotor (with blades stretching 73.50 m), the turbine has a yield 15% better than existing offshore turbines, enabling it to supply power to the equivalent of about 5,000 households.

Developed for all offshore conditions, our 6MW direct drive wind turbine combines proven technology and innovation. Building on our unique Pure Torque* design, it provides high yield and uncompromising reliability that will lower the cost of offshore energy.

Key milestones

April 2012: The consortium led by EDF EN for which GE is the exclusive turbine supplier won three offshore wind farms in France (Saint-Nazaire, Courseulles-sur-Mer and Fécamp for a total of around 240 wind turbines).

December 2014: Type A certificate obtained, following the technology tests and performance measurement in Le Carnet, France, where GE installed the First Haliade* 150-6MW prototype.

End of 2013: GE installed the first Haliade prototype off the coasts of Ostend harbor at the Belwind site in Belgium. GE undertook commissioning tests and Operations & Maintenance demonstration and training. This installation helped GE confirming how the machine behaved within the offshore environment for which it was specifically designed and developed.

March 2016: GE installed and started additional testing and technology optimization at Osterild, Denmark.

August 2016: GE reached the financial close for the 396 MW Merkur offshore wind farm project, located in the North Sea, which will generate enough power for 500,000 homes. GE will supply 66 Haliade 150-6MW, and when completed, it will become one of Germany’s largest wind farms.

August 2016: GE installed America’s first offshore wind farm at Block Island, located off the coast of Rhode Island. This 30MW project will generate enough power to meet the needs of the residents of the island.

Thanks to its unique innovative and proven technology, GE is a key player in the offshore wind market, delivering efficient, reliable and environmentally-friendly power solutions to its customers.

A partnership in floating wind

Floating wind energy provides an innovative alternative for enhancing the energy potential of maritime settings that are too deep to install fixed-bottom foundations. Such settings usually provide better wind conditions while being more extensive and less travelled than near-coastal areas.

In October 2014, GE joins with DCNS to found a sector of excellence in the floating wind energy business. The partnership agreement aims at developing and then commercialising an integrated system for a semi-submersible floating wind turbine delivering 6 MW.

On August 2016, GE’s Haliade was selected as a preferred supplier (by EOLFI and CGN) for one of the first French floating offshore projects, located in Groix, 14 km off the coast of Brittany.


Innovative technology

  • The Pure Torque* design protects the generator to ensure and improves its performance by diverting unwanted stresses from the wind safely to the turbine’s tower though the main frame.
  • The innovative Advanced High Density direct-drive Permanent Magnet Generator (PMG) is more compact and lightweight design compared to earlier generation direct-drive systems.


  • GE’s unique and proven rotor support with direct-drive PMG increases reliability, maximises turbine availability and reduces maintenance costs.


  • Strength and durability are maximised with the 150m diameter rotor combined with 73.5m light blade.
  • Yield improved by 15% compared to the existing offshore turbines.
  • Supplying 5,000 households with electricity.
