Siemens has won orders for 23 units of its direct-drive turbines for five onshore projects in northern Germany.
Two of the wind farms are situated in Germany’s northernmost state of Schleswig-Holstein; the other three will be erected in Lower Saxony. Installation of all five projects – each comprising anywhere from one to eight of the gearless units – will be completed by spring 2017, says Siemens.
The first SWT-3.3-130 to be installed in Germany will be erected in Schleswig-Holstein by the end of this year in the municipality of Südermarsch. This unit, which Siemens is installing for Südermarsch Wind GmbH & Co., has an 85-meter hub height on a steel tower and a rotor diameter of 130 meters. Siemens says the model is designed to operate in moderate wind speeds and deliver a rated electrical generating capacity of 3.3 MW.
Six other turbines of this model make up the Damme Wind Farm project, being built in Lower Saxony. Owing to the wind conditions at this site, however, Siemens will install the units on steel tube towers with a hub height of 135 meters.
Both projects are scheduled to go online by the end of this year.
The five SWT-3.0-113 wind turbines that Siemens is installing on steel towers for the Beedenbostel Wind Farm – near the town of Celle in Lower Saxony – have a hub height of 115 meters. The 3 MW-class units, with rotors measuring 113 meters in diameter, are replacing five older turbines as part of a repowering project. The five new turbines will take up operation in early 2017. The operator is the Dean Group, headquartered in the town of Neustadt am Rübenberge.
Siemens is delivering eight more wind turbines of the same model – with a hub height of 92.5 meters – to customers innoVent and Jade Concept for the Bollenhagen Wind Farm, located in the Wesermarsch marshlands near the city of Oldenburg. Planning calls for the 24 MW project to begin commercial operations by the beginning of 2017.
The SWT-3.2-113 turbines Siemens is supplying for Denker & Wulf AG are destined for the Quarnbek Wind Farm. This trio of wind turbines, delivering a total output of 9.6 MW, is currently being installed in Quarnbek on the A210 Autobahn between Rendsburg and Kiel. Working in close cooperation with the developer, the project team accelerated construction times so that commissioning can take place before the end of this year, says Siemens.
“Our exceedingly economical gearless wind turbines are bestsellers in windy northern Germany, as these five new projects in Lower Saxony and Schleswig-Holstein underscore once again,” said Thomas Richterich, CEO of onshore wind of Siemens’ wind power and renewables division.
