At the European Wind Energy Conference and Exhibition in Warsaw, Siemens Energy, Erlangen, Germany, launched on 20 April 2010 its SWT-3.0-101 Direct Drive wind turbine for sale for onshore and offshore projects around the world. With 50% less parts, the new SWT-3.0-101, which will require less maintenance and increase profitability for customers at the same price of a geared turbine, has a rated power of 3 MW, and a rotor diameter of 101 meters. The SWT-3.0-101 features a new direct drive concept: a gearless drive train design with a compact, synchronous generator, excited by permanent magnets. The zero-series with up to 10 SWT-3.0-101 wind turbines will be installed in various parts of the world during 2010. Commercial serial production is expected to commence in 2011.

“Our new SWT-3.0-101 will offer 25 percent more power than our present 2,3-MW-machine, but with a lower weight and only half the parts. Our main target for the new machine was to reduce complexity in order to increase reliability and profitability”, said Henrik Stiesdal, CTO of the Siemens Wind Power Business Unit. A major advantage of the new machine is its compact design. With a length of 6.8 meters and a diameter of only 4.2 meters, the nacelle can be transported using standard vehicles commonly available in most major markets. “The nacelle of SWT-3.0-101 weighs only 73 tons, but despite the compact design, we have actually given our service technicians more space to operate – simply because we radically reduced the number of parts”, added Henrik Stiesdal. “This careful introduction of new products reduces risks for our customers and boosts the reliability and profitability of our technology.”
