Engineering and construction firm Mortenson says it will build wind energy projects in Iowa and Minnesota.

In Iowa, the firm was selected by MidAmerican Energy Co. to build two wind farms as part of the utility’s Wind XI Project, a plan to install 2,000 megawatts (MW) of wind energy in the state by 2019.

The new Arbor Hill and Ivester wind farms will be Mortenson’s 16th and 17th wind projects in the state for MidAmerican, and will add 341 MW of generating capacity.

In Minnesota, Mortenson will build the 200 MW Blazing Star wind farm in the southwest part of the state for Xcel Energy. The utility plans to add 1,850 MW of wind energy in Minnesota, South Dakota, North Dakota and Iowa by 2030.

Mortenson says it will have installed around 3,000 MW of wind energy for MidAmerican Energy, and more than 4,000 MW of wind energy in Iowa over the past 23 years.

The Arbor Hill wind farm in Iowa will include 125 Vestas turbines with tower hub heights of 95 meters, totaling 250 MW of generating capacity.

The Ivester project will consist of 35 Siemens Gamesa turbines with a combination of tower heights of 85.1 meters and 80 meters totaling 91 MW of capacity.

The scope of work for both Iowa projects includes access roads, foundations, collection system installation and placement of the turbines. Mortenson will handle all civil and high voltage work associated with these projects.
