Siemens plans to invest €150 million over the next two years to expand its wind power business. The company is contemplating to open two research and development centres, and an offshore “centre of excellence” in Denmark. Siemens Wind Power CEO Jens-Peter Saul said further factories were being planned in the UK, Canada, Russia and India.
Meanwhile, Siemens has won its first ever offshore turbine order in China. Guodian-subsidiary Longyuan has given the manufacturer a 48 MW deal for the Rudong inter-tidal project located in Rudong county, Jiangsu province, western China. The project will use 21 Siemens SWT-2.3 MW, 101 turbines. The contract also includes a five-year service agreement. The turbine’ blades will be manufactured at its new Chinese facility.
In October last year, Longyuan won a tender to develop the 200 MW Dafeng offshore project.
In yet another development, Siemens has installed the first prototype of its 6 MW offshore wind turbine, the SWT-6.0-120, with direct drive technology. The prototype has been installed at Høvsøre in Denmark. The offshore wind turbine’s nacelle and rotor weigh under 350 tonnes, something that could cut the cost not only of the nacelle, but also the tower and supporting structures, Siemens says.
“In tendency large wind turbines have always been heavier per megawatt than small ones. The SWT-6.0-120 breaks this rule, having a weight per MW similar to that of many turbines in the 2-3 MW range,” says Henrik Stiesdal, CTO, Siemens Wind Turbine Business Unit. Serial production of the 6 MW offshore wind turbine is scheduled for 2014.
