The contract includes delivery and commissioning of the turbines along with a five-year service and maintenance agreement.
Delivery of the turbines is scheduled for late summer 2011 and commissioning is expected by the end of next year.
Minneapolis-based energy management services provider Avant Energy is managing this power project.
Vestas Americas president Martha Wyrsch said that the V90-1.8MW turbine is specifically designed to provide maximum power output at sites with medium wind speeds.
"Minnesota is one of the leading states for wind power, and we are excited to help create more clean, reliable energy here. This project also will result in construction jobs and long-term local maintenance positions to be hired by Vestas," Wyrsch said.
