HUTCHINSON, Kan. — The Hutchinson Siemens Gamesa plant has been awarded a new contract from MidAmerican Energy.

Siemens Gamesa will supply the turbines for the Rolling Hills wind power project with 429.3 MW capacity.

The company will repower the project with 163 SG 2.7-129 and 18 previously sold SWT-2.3-108 wind turbines.

Rolling Hills 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, Siemens Gamesa said on Tuesday.

MidAmerican Energy Company will start commissioning of the project in late 2021.

Siemens Gamesa has installed nearly 1,400 wind turbines for a total of almost 3.5 GW in Iowa alone. The blades for the project will come from Fort Madison, Iowa, and the new component from the facility in Hutchinson.
