Siemens introduces new 3.6-megawatt wind turbine featuring a 120 meter rotor diameter

The turbine has a swept area of 11,300 square meters, which is equivalent to nearly two football fields. “We anticipate that our new SWT-3.6-120 wind turbine will generate roughly ten per cent more electricity at a typical offshore site compared to our SWT-3.6-107,” said Andreas Nauen, CEO of the Siemens Wind Power Business Unit.

“With this new wind turbine we will continue to maintain our technology leadership in offshore wind energy. We have already seen a lot of interest from the market in this new product.” The SWT-3.6-120 extends the performance of the proven Siemens 3.6 MW wind turbine type, which is already established as the preferred offshore turbine type in the multi-megawatt class. Siemens has installed 100 of its 3.6 MW wind turbines and has another 700 turbines on order.

Earlier this year Dong Energy signed orders for more than 450 SWT-3.6-120 machines. 175 of these new wind turbines will be installed in the first phase of the British London Array project, which will ultimately be the world’s first offshore wind farm on a gigawatt-scale. Furthermore, 51 SWT-3.6-120 wind turbines will be installed at the Walney II Offshore Wind Farm, also in the U.K.

These orders from Dong Energy are part of the world’s largest wind power agreement for the supply of up to 500 offshore wind turbines, which was signed earlier this year. The wind turbines to be delivered under the supply agreement will have a total capacity of up to 1,800 megawatts.

The first two prototypes of the SWT 3.6-120 will be used by Dong Energy at Avedøre in Copenhagen, and installed in time for the COP 15 / UN World Climate Summit in Copenhagen. The Hvidovre Vindmøllelaug, a group of local investors, is contributing to this project.

Wind turbines are an important component of the Siemens environmental portfolio, which earned the company revenues of nearly EUR19 billion in fiscal 2008, roughly a quarter of the company’s total revenues. Today, Siemens is the world’s leading supplier of environmentally friendly technology.

The Siemens Energy Sector is the world’s leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas.

In fiscal 2008 (ended September 30), the Energy Sector had revenues of approximately EUR22.6 billion and received new orders totaling approximately EUR33.4 billion and posted a profit of EUR1.4 billion. On September 30, 2008, the Energy Sector had a work force of approximately 83,500.
