Siemens launches offshore wind turbines of 7MW

Siemens announced the launch of its new flagship offshore wind turbine, which it says generates nearly 10 percent more power annually than its predecessor.


The new wind turbine of seven megawatt (MW), called SWT-7.0-154, was presented at the ongoing EWEA Offshore 2015 conference that opened Tuesday in Copenhagen.

Siemens has added stronger permanent magnets and generator segments in the permanent magnet generator for higher yield, according to Michael Hannibal, Offshore CEO of Siemens Wind Power and Renewables.

In addition, the converter and transformer have been upgraded in line with the higher electrical output, Hannibal said.

“Our new wind turbine offers our customers an investment as reliable as our proven G4 and D6 product platforms,” Hannibal said. “Yet it also answers market demands to achieve greater energy yield at lower cost and effort.”

The new model is set to go into series production by 2017, the company said. Meanwhile, the 6-MW-version will continue to be available for sales.
