Rolling Hills Wind Project Proceeding On Schedule


Construction of the 443.9 MW Rolling Hills wind project in southwest Iowa is progressing on schedule toward a planned year-end completion, according to officials from MidAmerican Energy Co., Mortenson Construction and Siemens Energy.

Company representatives gathered with community leaders and local residents at the site to showcase the project. A wind turbine blade, manufactured at Siemens' blade manufacturing plant in Fort Madison, Iowa, was displayed at the event.

Siemens is supplying 193 of its SWT-2.3-101 wind turbines to the project, located in Adair, Adams and Cass counties. Each turbine is capable of producing 2.3 MW of energy.

Mortenson Construction is installing the wind turbines, as well as constructing the balance of the project infrastructure, which includes approximately 37 miles of access roads and 139 miles of underground wiring.

Rolling Hills is one of three MidAmerican Energy wind projects underway in Iowa this year. Wind turbines also are being constructed in Calhoun, Marshall and Pocahontas counties.
