Siemens Unveils 7MW Offshore Wind Turbine

Siemens has presented its new SWT-7.0-154 wind turbine at EWEA Offshore conference in Copenhagen. 

After setting standards with its flagship 6MW offshore wind turbine, the SWT-6.0-154, Siemens today introduced a generator upgrade to seven megawatt (MW), the new Siemens SWT-7.0-154.

The turbine delivers nearly ten percent more energy production than the predecessor under offshore wind conditions, while retaining the same proven reliability, Siemens said. Development engineers have refined solely those turbine components needed to increase electrical output.

The new model is set to go into serial production by 2017.

Stronger permanent magnets and generator segments in the permanent magnet generator provide the key to harvesting a higher yield. Additionally, the converter and transformer have been upgraded, in line with the higher electrical output. All other components remain the same tried and proven engineering of the 6-MW wind turbine, giving Siemens’ customers the assurance of relying on proven technology and supply chain while significantly increasing energy production. The 6-MW-version will continue to be available for sales but following the improvements, Siemens has renamed the product platform to D7.

Siemens is presenting its new SWT-7.0-154 to the world’s experts at the international wind power conference and exhibition EWEA Offshore 2015 in Copenhagen. The product is yet another innovative step by the company to lower the cost of generating electricity on the high seas. “Our new wind turbine offers our customers an investment as reliable as our proven G4 and D6 product platforms,” notes Offshore CEO Michael Hannibal of Siemens Wind Power and Renewables. “Yet it also answers market demands to achieve greater energy yield at lower cost and effort.”

The turbine’s long structural design lifetime of 25 years and increased power rating create a remarkable cost of energy benefit.
