Mortenson to Make History with MidAmerican Energy

Mortenson Construction is excited to continue its relationship with MidAmerican Energy Company by building its 12th wind farm for the utility.  MidAmerican Energy has selected Mortenson to construct the 170-MW Beaver Creek wind farm in Iowa. The Beaver Creek wind farm is part of MidAmerican Energy’s Wind XI expansion that will add 2,000 megawatts of wind generation capacity in Iowa.

Mortenson, a leading renewable energy contractor who has built 51% of all the wind in Iowa, will now be a part of the largest economic development investment in Iowa’s history.  

“We are pleased to be part of Iowa’s leadership in wind energy.  It was in Iowa where we entered the wind energy market in 1995 by erecting our first turbine near Adair,” commented Tim Maag, VP and General Manager of Mortenson’s Wind Energy Group.

The Beaver Creek wind farm is being constructed across Greene and Boone counties near the town of Grand Junction, Iowa, and will consist of 85 turbines. Vestas will provide the V110 turbines that are scheduled for delivery this month and are expected to be in-service December 2017.

The Beaver Creek wind farm is expected to create 150 temporary construction jobs.
