To meet the threat from Haliade-X, Vestas is now presenting a wind turbine with 115.5 meters long blades. Their rotation thus covers the largest area in the world.
GE Renewable Energy used to sit on the world’s largest offshore wind turbine. Haliade-X has a capacity of up to 14 MW, and the 107 meter long blades provide a rotor with a diameter of 220 meters. The dimensions together with the high capacity should be according to the manufacturer make the wind turbine less sensitive to wind variations, with the capacity to generate more energy at low wind speeds.
General Electric recently secured space for Haliade-X 14 MW for phase C of the large Dogger Bank Wind Farm at Doggers banks in the North Sea, which will be completed in 2026. The competitor’s success is of course annoying for Vestas, but the Danish company’s new wind turbines poking down Haliade-X from the throne.
Vestas V236-15.0 MW has, as the name suggests, a capability that surpasses GE’s giant. The Danish wind turbine also has much longer blades. They are 115.5 meters long, which gives a rotor with a diameter of 236 meters. Thus, Vestas has the record with the largest swept area – at 43,742 square meters.
Can supply 20,000 European homes with electricity
There are benefits to being great. According to Vestas, the V236 can withstand wind speeds of up to 57 seconds, which means that the spinner must withstand conditions that are worse than Hurricane Gudrun, with gusts of 42 seconds.
For one year, Vestas reckons that V236-15.0 MW, slightly depending on site conditions, will be able to deliver approximately 80 GWh. This means that a wind turbine can supply 20,000 European homes with electricity. If electricity replaces fossil production, more than 38,000 tonnes of carbon dioxide can be saved, which corresponds to 25,000 cars removed.
According to the manufacturer, the capacity, which for example is 65 percent higher than what the V173-9.5 MW delivers on an annual basis, means that wind farms can cope with fewer spins. A wind farm of 900 MW could remove 34 wind turbines and still increase its production by five percent. The first prototype will be installed in 2022, and put into production in 2024.
