MidAmerican Energy Co. says that in 2012, the company completed three wind farms totaling 407 MW in Iowa. With these projects complete, wind power makes up 30% of the company's portfolio.
In January 2012, MidAmerican acquired the 106 MW Vienna wind project, located in Marshall and Tama counties; the 200 MW Eclipse wind project, located in Guthrie and Audubon counties; and the 101 MW Morning Light wind project, located in Adair County. The three projects consist of 176 wind turbines.
The wind turbines for MidAmerican Energy’s 2012 wind expansion were supplied by Siemens, with the blades manufactured at its Fort Madison, Iowa, facility. The Vienna wind project was constructed by Mortenson Construction, while the Eclipse and Morning Light wind projects were constructed by Wanzek Construction.
