Siemens Gamesa will fulfill the largest repowering order to date in North America by supplying turbine and equipment replacement for Iowa's Rolling Hills wind power project, according to the company's announcement on Tuesday.

Siemens Gamesa has been selected by MidAmerican Energy Company to repower the project for a total of 429.3 megawatts (MW).

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.

"The company will repower the project with 163 SG 2.7-129 and 18 previously sold SWT-2.3-108 wind turbines," the company stated, adding that commissioning of the project is expected for late 2021.

Siemens Gamesa has installed more than 10,000 wind turbines in the U.S. totaling approximately 20 GW of installed capacity. In Iowa, Siemens Gamesa has installed nearly 1,400 wind turbines for a total of almost 3.5 GW.
