Siemens Gamesa unveiled 14MW offshore wind turbine
Wind turbine manufacturer Siemens Gamesa has unveiled a 14-megawatt (MW) capacity new SG 14-222 DD offshore Direct Drive wind turbine.
Using the company's Power Boost feature, a 222-meter rotor diameter, 108-meter long blades and a sweeping area of 39,000 m2 the power can reach up to 15 MW.
The 14 MW capacity allows one SG 14-222 DD machine to deliver enough energy each year to power around 18,000 average European households.
In addition, roughly 30 SG 14-222 DD offshore wind turbines could cover Bilbao, Spain's annual electricity consumption, Siemens Gamesa said.
The rotor has a diameter of 222 meters and uses the new Siemens Gamesa B108 blades, each 108 meters long.
The company also says the massive 39,000 m2 swept area of the turbine is equivalent to roughly 5.5 standard football pitches.
"It allows the SG 14-222 DD to provide an increase of more than 25% in Annual Energy Production compared to the SG 11.0-200 DD offshore wind turbine," the company said.
"Furthermore, the new offshore giant features a low nacelle weight at 500 metric tons. This light weight enables Siemens Gamesa to safely utilize an optimized tower and foundation substructure compared to a heavier nacelle. Benefits thus arise in the form of lower costs per turbine by minimizing sourced materials and reducing transportation needs."
