MidAmerican Energy Company has selected Siemens Gamesa to repower the 429.3 MW Rolling Hills wind power project. This is the largest repowering order in North America to date. Siemens Gamesa will repower the project with 163 SG 2.7-129 and 18 previously sold SWT-2.3-108 wind turbines.

The Rolling Hills project is located in Adair, Adams, and Cass counties in Iowa, and currently features 193 SWT-2.3-101 turbines. The repowering project includes replacement of the blades, hubs, and nacelles for all units, and top tower sections for the SG 2.7-129 units. Commissioning of the project is expected for late 2021.

The SG 2.7-129 builds on the 2.3MW geared product series.

José Antonio Miranda, CEO of Onshore Americas at Siemens Gamesa Renewable Energy, said: “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 2.6GW. The blades will be produced in Iowa, and the nacelles and hubs will come from Kansas.”
