Mortenson has been selected by MidAmerican Energy to build two wind farms in Iowa as part of the company’s Wind XI Project, a broader plan to install 2,000MW 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 built in the state for MidAmerican Energy, adding 341MW to Iowa’s electric grid.
Arbor Hill, located in Adair County, includes 125 Vestas turbines with tower hub heights of 95 meters, totaling 250MW of output. The Ivester project, located in Grundy County, is approximately 130 miles from Arbor Hill and consists of 35 Siemens Gamesa turbines with a combination of tower heights of 85.1 meters and 80 meters totaling 91MW. The scope of work for both projects will include access roads, foundations, collection system installation and erection of the turbines. Mortenson will self-perform all civil and high voltage work associated with these projects.
