Siemens reveals gearless wind turbine as COP15 swings into action  

2009.12.07
Siemens Wind Power has installed a prototype of a 3 MW gearless onshore wind turbine which could revolutionise the wind industry
This week, when delegations from 192 countries gather at the UN Climate Change Conference COP15 in Copenhagen to attempt to establish a new global treaty on climate change, Siemens Wind Power has revealed an invention which could herald a new era in the global wind industry – a prototype of a 3 MW gearless wind turbine. The news is reported by Erhvervsbladet.
 
Last week, Siemens Wind Power disclosed that it has been developing a prototype of a gearless wind turbine since 2005, which has just been installed near Brande where the company is headquartered. The wind turbine, designated SWT-3.0-101, has a 90 metre high tower and a rotor diameter of 101 metres, giving a swept area of over 8,000 square metres. It is planned to start producing electricity this week.
 
Henrik Stiesdal, head of technology at Siemens Wind Power says: "After having tested gearless wind turbines for 18 months, we are confident that this technology can provide a good foundation for future product development. This is a great technological step forward for Siemens. Gearless wind turbines could become a significant bestseller for us in the future."
 
Siemens has invested DKK 50m (USD 10.1m) in the development of SWT-3.0-101, which will be introduced on the market next year. If everything goes according to plan, Siemens will expand sales in 2011.
 
Germany's Enercon is currently the only manufacturer worldwide which produces gearless wind turbines, while China's Goldwind, according to industry information, is planning to start production at some point. If Enercon and Goldwind can cope with competition with Siemens' new invention, competition for customers is set to intensify.
