Des Moines, Iowa — MidAmerican Energy has released more details about a plan to add nearly 450 wind turbines across the state. Construction is underway on the project in O’Brien County, as well as other projects in Webster, Grundy, Madison, and Marshall Counties. The utility has announced the blades for the expansion will be manufactured by a Siemen’s plant located in Fort Madison.
MidAmerican Energy recently reached an agreement with Highland Wind Energy, LLC, an Invenergy Wind LLC company, for the acquisition of the approximately 500-megawatt Highland wind project site in O’Brien County. Agreements also were reached with EDF Renewable Energy for the acquisition of the approximately 250-megawatt Lundgren wind project site in Webster County, and with two RPM Access, LLC companies for the acquisitions of the approximately 138.6-megawatt Wellsburg wind project site in Grundy County and the approximately 117-megawatt Macksburg wind project site in Madison County. In addition, MidAmerican Energy’s existing Vienna wind farm, constructed in 2012, is being expanded by 44.6 megawatts in Marshall County, and is being called the Vienna II wind project.
The Highland wind project in O’Brien County as well as the Macksburg and Wellsburg wind projects will be constructed by Mortenson Construction, which is based in Minnesota. The Lundgren and Vienna II wind projects will be constructed by Wanzek Construction, Incorporated, which is based in North Dakota.
Once completed by the end 2015, MidAmerican officials say the new wind projects will generate enough electricity to power the equivalent of 317,000 Iowa households.
