Mortenson Construction says it has commenced construction on the Shady Oaks Wind Farm near Compton, Ill., which will add 109.5 MW to the state's wind energy capacity.
The wind power facility will consist of 71 Goldwind turbines. Mortenson is responsible for the design and construction of the access roads, collection system and foundations, as well as the erection of the turbines.
Construction on the project is expected to be complete in early 2012.
