Proven technology and innovation

Thanks to its 150-meter diameter rotor (with blades stretching 73.50m), the Haliade 150-6MW turbine can supply power to the equivalent of about 5,000 European homes. Currently, this offshore wind turbine is powering the state of Rhode Island. Located on Block Island, GE constructed and installed the first offshore wind farm in the USA in 2016.

Developed for all offshore conditions, our 6 MW 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 and create more efficient offshore turbines.

Innovative technology: Pure Torque and Direct Drive

  • The Pure Torque design protects the generator to ensure and improve 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 offshore wind turbine’s 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, enhances offshore wind turbine availability and reduces maintenance costs.


  • Strength and durability are increased with the 150m diameter rotor combined with 73.5m light blade.
  • Yield is improved by 15% compared to existing offshore wind turbines.
  • Supplies enough electricity for 5,000 European households.

A partnership in floating wind

Floating offshore wind turbines provide 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.

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 238 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.

December 2014: GE inaugurated the offshore wind turbine rotor and nacelle assembly factory in Saint-Nazaire, France.

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

August 2016: 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 Merkur is completed, it will become one of Germany’s largest wind farms.

August 2016: GE installed the first offshore wind farm in the US at Block Island, located off the coast of Rhode Island. This 30 MW project generates enough power to meet the needs of the residents of the island. See how the Block Island wind farm was installed using a magnetic rotor design.

March 2017: GE Renewable Energy was selected by Chinese Fuqing Haixia Electricity Generation  Company (a joint venture between China Three Gorges and Fujian Energy) to deliver  three Haliade 150-6MW offshore wind turbines to the Fujian Xinghua Gulf demo  project. GE is one of the several wind turbine suppliers to participate in the 73 MW windfarm project, capable to provide enough power to satisfy the needs of more than 20,000 households in the region.

March 2018: GE finished the installation of the Xinghua Gulf demo project, and became the first supplier in the world to have installed offshore wind turbines in the Americas, Europe, and Asia.

March 2018: GE announced the installation of the first Haliade 150-6MW at the Merkur offshore windfarm in Germany. Installation and commissioning activities are on-going.

September 2018: Finish the successful installation of the 66 Haliade 150-6MW offshore wind turbines at the 396MW Merkur Offshore Windfarm in Germany.
