Jeffers Wind Farm

Jeffers, Minnesota

In the heart of rural southern Minnesota, the Jeffers Wind Farm stands amongst acres of farmland. The client was on a tight deadline for this project and wanted the foundations poured before winter hit. Starting in November, Thorstad constructed 20 foundations, 19,500 feet of road, and 43,000 feet of collection system in 22 days to meet this deadline.

Thorstad’s role in this project included design and construction of roads, foundations, and the operations and maintenance building.

Project was completed in December 2006.
