Nacelle installed on GE Haliade-X 12 MW turbine

The Nacelle of the largest offshore wind turbine in the world Pondera GE Haliade-X 12 MW has been successfully installed at the Maasvlakte in Rotterdam.

Key figures for the Haliade-X 12 MW

Capacity: 12 MW
Rotor diameter: 220 m
Blade length: 107 m
Hub height: 150 m
Tip height: 260 m
Wind turbine swept area: 38,000 m2
Annual energy yield: approx. 67 GWh

General information

Pondera Development and SIF Holding, together with GE Renewable Energy, are developing the Haliade-X on the Maasvlakte 2 in Rotterdam. The development of the innovative Haliade-X project in Rotterdam has been made possible thanks to Pondera’s extensive knowledge and many years of experience in Dutch wind energy legislation and regulatory policy. The increase in size and scale of (offshore) wind turbines is an important step in generating more sustainable energy, accelerating the energy transition and thereby limiting the effects of climate change.

The offshore wind turbine prototype will be installed onshore in order to ease access for testing and monitoring purposes. This will also allow GE to collect the data needed to obtain the Type Certificate, a key step in commercializing the Haliade-X.

The Haliade-X can generate 67 GWh of electricity annually. That is enough power for 16,000 European households and thus saves 42 megatons of CO2. In the fall of 2019, the Haliade-X will generate renewable energy on the SIF site on the Maasvlakte.

Pondera and Sif to build the largest wind turbine in the world

  • Agreement signed with Future Wind includes five years of testing and 15 years of service
  • Installation of Haliade-X 12 MW will take place during summer 2019

GE Renewable Energy and Future Wind (a Joint Venture between Pondera Development and SIF Holding Netherlands) announced today that they have signed an agreement to install the first Haliade-X 12 MW wind turbine prototype in Maasvlakte-Rotterdam (NL) during summer 2019. The deal includes five years of testing and a 15-year full service Operation and Maintenance agreement.

This Haliade-X 12 MW prototype will be installed onshore to facilitate access for testing. During the initial period of operations, it will allow GE Renewable Energy to collect data needed to obtain a Type Certificate, a key step in commercializing the product in 2021.

Activities in Rotterdam to prepare the site for future installation have just begun. The nacelle of the Haliade-X 12MW prototype will be assembled in Saint-Nazaire (France), while the three 107 meter-long LM Wind Power blades will be manufactured in Cherbourg (France), and the tower sections will be produced in Seville (Spain). All components will be shipped to Rotterdam, where pre-assembly work and installation will take place.

This prototype in Rotterdam is part of the $400 (€320) million investment in the Haliade-X development announced by GE Renewable Energy in March 2018 to help reduce offshore wind’s cost of energy in order to make it a more competitive source of clean, renewable energy.
