From the “bigger they are, the harder they fall” department comes this monster from General Electric:
GE Renewable Energy GE will invest more than USD 400 million over the next three to five years to develop and deploy the largest, most powerful offshore wind turbine – the Haliade-X 12 MW.
Featuring a 12MW direct drive generator and a capacity factor of 63 percent, the Haliade-X will produce 45 percent more energy than any other offshore turbine available today, the company said.
GE Renewable Energy aims to supply its first nacelle for demonstration in 2019 and ship the first Haliade-X units in 2021.
Towering 260 meters (853 feet) over the sea, more than five times the size of the Arc de Triomphe in Paris, France, the Haliade-X 12 MW carries a 220-meter rotor.
Designed and manufactured by LM Wind Power, the 107-meter-long blades will be the longest offshore blades to date and will be longer than the size of a soccer field.
Jérôme Pécresse, President and CEO of GE Renewable Energy said:
“The renewables industry took more than 20 years to install the first 17 GW of offshore wind. Today, the industry forecasts that it will install more than 90 GW 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.”
AN INDUSTRY FIRST
Introducing the Haliade-X 12 MW, the most powerful offshore wind turbine in the world to date, featuring a 12 MW capacity (the world’s first), 220-meter rotor, a 107-meter blade designed by LM Wind Power, and digital capabilities. In addition to being the biggest offshore wind turbine, the Haliade-X will also be the most efficient of wind turbines in the ocean. Best of all, it’s capable of transforming more wind into power than any other offshore wind turbine today.
The Haliade-X 12 MW also features a 63% capacity factor*—five to seven points above industry standard. Each incremental point in capacity factor represents around $7 million in revenue for our customers over the life of a windfarm.
The offshore wind turbine design of the Haliade-X is what makes it unique. The combination of a bigger rotor, longer blades and higher capacity factor makes Haliade-X less sensitive to wind speed variations, increasing predictability and the ability to generate more power at low wind speeds. The Haliade-X can capture more Annual Energy Production (AEP) than any other offshore wind turbine even at low wind conditions.
This 12 MW ocean wind turbine can also generate 67 GWh annually, which is 45% more AEP than the most powerful machines on the market today, and twice as much as the Haliade 150-6MW. One Haliade-X 12 MW can generate enough clean power to supply 16,000 European households according to wind conditions on a typical German North Sea site. Based on a 750 MW windfarm and an estimated AEP, the Haliade-X 12 MW could produce enough power for up to 1 million households.

No word yet on what the “carbon footprint” of producing and installing this beast is, and whether it will actually going to offset its own footprint during its useful operational lifetime.
Given what happened at the wind farm in Punta Lima, Playa Hucares, Puerto Rico when Category 4 Hurricane Maria made landfall on September 24th, one wonders if the materials in this monster turbine are up to the task of scaling up the size. The wind loading would be massive and untested, and could only be modeled.
