Duke Energy has selected Siemens turbines for its 168MW Ironwood Windpower Project in Ford County in the US state of Kansas.

The company will use 73 Siemens turbines, each with a generating capacity of 2.3MW, to construct the wind farm.

Duke Energy Renewables, a commercial business unit of Duke Energy, will build, own and operate the power project which will generate enough electricity to power more than 50,000 homes.

The company plans to begin construction of the wind farm in the fall of 2011, with commercial operation expected by mid-2012.

The electricity and associated renewable energy credits produced by project will be purchased by Westar Energy under a 20-year agreement.

Siemens’ new manufacturing facility in Hutchinson, Kansas, will supply the nacelles that will sit atop the 73 wind turbine towers at the wind farm.
