Siemens Energy has launched its new 6MW direct drive wind turbine. The new SWT-6.0 will be available with rotor diameters of 120 and 154 meters. It features the Siemens direct drive design with 50 per cent fewer parts than comparable geared wind turbines.

With a towerhead mass of roughly 350 tons, the SWT-6.0 is the lightest machine in its class. The entire electrical system of the new 6-MW machine – including the medium voltage system and the full converter – is now enclosed in the nacelle. A helicopter-hoisting platform is integrated in the nacelle rear. The first prototype of the Siemens 6MW turbine was installed in May, 2011 at Høvsøre, Denmark. Siemens is currently in the process of thoroughly testing and validating the performance of the turbine. A pre-series of up to 50 SWT-6.0 wind turbines will be installed at on- and offshore sites in Denmark, Germany, The Netherlands and in the UK during 2012 and 2013.
