MidAmerican Energy Company has selected Siemens Gamesa for its 429.3-MW Rolling Hills wind power project in Iowa — the largest repowering order to date in North America. The company will repower the project with 163, SG 2.7-129 and 18 previously sold SWT-2.3-108 wind turbines.
The project includes replacement of the turbine blades, hubs, and nacelles for all units, and the top tower sections for the SG 2.7-129 units. Commissioning of the project is expected for late 2021.
“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,” stated José Antonio Miranda, CEO of Onshore Americas at Siemens Gamesa Renewable Energy.
He added: “The blades will be produced right there in Iowa and the nacelles and hubs will come from neighboring Kansas, making this a truly local project.”
In Iowa, Siemens Gamesa has installed nearly 1,400 wind turbines for a total of almost 3.5 GW. The company has a strong footprint consisting of service, offices and two manufacturing facilities located in Fort Madison, Iowa, and Hutchinson, Kansas.
