Located in Iowa, the Rolling Hills wind power project currently features 193 SWT-2.3-101 turbines. The repowering project also includes replacement of blades, hubs and nacelles for all units, and top tower sections for the SG 2.7-129 units.

The nacelles and hubs will be brought from the company’s nacelle and hub assembly facility in Hutchinson, Kansas, while the blades will come from the blade manufacturing facility in Fort Madison, Iowa. The project is expected to be commissioned in 2021.

Siemens Gamesa Renewable Energy CEO of onshore Americas José Antonio Miranda said: “We are excited to provide upgraded equipment and technology to the Rolling Hills project in Iowa, a national leader in the wind energy industry.

“This new project is a testament to MidAmerican Energy’s confidence in us as well as Iowa, where we have supplied them with more than 2.6 GW.
