Odin Wind Farm

Odin, Minnesota

In the heart of wind country, the Odin Wind farm is located in the rural county of Watonwan in southern Minnesota. Miles of farmland stretch as far as the eye can see.

While there were few above ground challenges, the soft soils in the area required creative solutions. A strategy was required to compensate for the soft soils during the construction of the roads, as well as the crane paths and pads. The weight of the crane and its movement from site to site was also taken into consideration.

To meet the project’s schedule requirements and neutralize the challenge of the soft soils,
foundations were laid during the summer months and the wind turbines were erected in December.

Thorstad’s role on this project was an EPC contractor. Thorstad designed and constructed the roads, foundations, and substation, erected the wind turbines and installed the collection system for this project.

Project was completed March 2007.
