MidAmerican Energy recently reached an agreement with Highland Wind Energy, LLC, an Invenergy Wind LLC company,
for the acquisition of the approximate 500-megawatt Highland wind project site in O’Brien County. Agreements
also were reached with EDF Renewable Energy for the acquisition of the approximate 250-megawatt Lundgren wind
project site in Webster County, and with two RPM Access, LLC companies for the acquisitions of the approximate
138.6-megawatt Wellsburg wind project site in Grundy County and the approximate 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 (Vienna II wind project).
Once complete, the new wind projects, which will consist of 448 wind turbines, will generate enough electricity
to power the equivalent of approximately 317,000 average Iowa households.
