MidAmerican Energy has selected US contractor Mortenson to build the 250MW Arbor Hill and 91MW Ivester wind farms in Iowa.
Arbor Hill, which is located in Adair County, will feature 125 Vestas turbines with hub heights of 95 metres, while Ivester in Grundy County will comprise 35 Siemens Gamesa machines with 80-metre hub heights.
