Haliade-X turbine will generate 12MW with a 63 per cent capacity factor, and stands 260m tall.

The new wind turbine, whose launch was announced yesterday in Paris, will produce 45 per cent more energy than the current largest turbine available. Each unit is claimed to have the ability to produce 67GWhr of energy per year, sufficient to power up to 16,000 typical European households. Its large size will enable offshore wind farm operators to reach their power goals using fewer wind turbines, thereby reducing capital expenditure, risk in project execution and simplifying maintenance and operation.

The Haliade-X is a truly enormous beast, towering 260m above sea level. In keeping with the location of the launch, GE stated that it is five times the height of the Arc de Triomphe; British readers may not realise that the Arc de Triomphe is roughly the same height as Nelson’s Column. More comparisons with well-known buildings can be seen in the infographic above.
Each blade of the turbine is 107m long, making a total rotor diameter of 220m. The blades were designed, and will be manufactured, by LM Wind Power, a Danish blade specialist acquired by GE in 2016, which manufactures in Europe, North and South America and Asia.

Jérôme Pécresse, president and CEO of GE Renewable Energy said: “The renewables industry took more than 20 years to install the first 17GW of offshore wind. Today, the industry forecasts that it will install more than 90GW over the next 12 years. This is being driven by lower cost of electricity from scale and technology. The Haliade-X shows GE’s commitment to the offshore wind segment and will set a new benchmark for cost of electricity, thus driving more offshore growth.”
The capacity factor of the turbine is a significant development. Indicating how much energy is generated compared with the maximum that could be generated at continuous full power operation, it indicates what fraction of the nameplate capacity can be expected during average wind conditions. At 63 per cent, the Haliade X is five to seven points ahead of the current industry benchmark. Therefore, GE says, it will produce more energy per megawatt installed, “which will significantly increase returns for customers.”
John Lavelle, CEO of Offshore Wind at GE Renewable Energy said: “The Haliade-X 12MW will help our customers in an increasingly competitive offshore environment, and through its size and digital functionality provide important value across manufacturing, installation and operation.”
GE is to invest $400m in developing and deploying the Haliade-X over the next three to five years, and anticipates that the first deployment could be in 2021.
I had the vague understanding that they were big. The infographic is a real eye-opener. Wow.
Very interesting and impressive.
“Today, the industry forecasts that it will install more than 90GW over the next 12 years.”…I wonder how that compares to nuclear industry projections? I also wonder which one is more cost effective?
Hello subsidy free Energy Generation 🙂
Stunning technology -that of aerofoil lift!- in an new/enhanced application. If we accept that the ‘lift’ from the wings of a Jumbo/Airbus aircraft (somewhat similar in size too) can support the forces they do: the full potential of a turbine to generate starts to become obvious.
I wonder what the tip speed will be and what is the clearance from the bottom tip above the crest of a huge swell in a king tide, enough for a large cruise ship? That would make a good disaster movie. A question (to Andrew J’s comment) – what is the true cost of nuclear power once we factor in the various governments and nuclear agencies of the world cleaning up all the mess of decommissioning and the accidents that have happened?
There have been reports of major problems with the early off-shore turbines, which are much smaller than these. The problems seem to relate to the erosion / corrosion damage to blades and the cyclic stresses on the undersea foundations. The rapid expansion of technologies always raises problems that can cost enormous sums to correct. The use of even bigger blades could prove very expensive.
Fortunately, GE and Siemens are both wealthy companies who have had massive subsidies from all of us for their white elephants!
I’d be interested to know more about the economics of this turbine. For example:
How long is it expected to remain operational?
What will be the cost per Kwh over its planned life cycle, allowing for maintenance and financing costs?
How does this compare with alternative renewable energy approaches?
Oh…and one other thing…where are such behemoths likely to be located?
And energy storage? It is one thing to be able to generate when the wind blows i is quite another to be able to supply when it does not.
All kudos to GE and their partner companies for developing this fantastic new wind turbine.
It is irritating that the artist felt the need to exaggerate it’s size in the first graphic. The total height of a wind turbine is measured to the tip of one of the blades when it is pointing straight up. If the wind turbine in the graphic is adjusted so that one blade is pointing straight up, it becomes much taller than the Eiffel Tower. But the Eiffel Tower is reported as 1063 ft and the wind turbine is only 853 ft. So something is amiss.
