Mortenson's Wind Energy Group was selected by MidAmerican Energy Company (MEC) to construct the 250.3-megawatt O’Brien Wind Project, our 150th wind project. This was the 11th project constructed for the customer.
O’Brien Wind Project is an expansion of Highland Wind Project, a 500 MW project completed in 2015. Construction commenced in late April 2016 and completed later that year in December.
Our scope of work included access roads, foundations, underground collection and erection of 91-Siemens SWT 2.416-MW and 13-Siemens SWT 2.346-MW turbines.
With the completion of Ida Grove and O’Brien, Mortenson has installed nearly 3,400 MW of clean energy in the state of Iowa alone, which is 55% of all wind energy installed in Iowa.
