The company has received a three-year extension from Alliant Energy to provide service and maintenance at the Whispering Willow Wind Farm – eastern Iowa.
Under the agreement, Vestas will carry out scheduled maintenance and monitor and remotely control the turbines with the VestasOnline surveillance system.
Senior Vice President of Energy Resource Development at Alliant Energy Tom Aller said: "Renewable energy is a key component of our long-term energy resource supply. As a result, we need a company that can keep our wind generating facilities operating at an optimum level. Vestas is an industry leader in servicing and maintaining wind generating facilities."
Vestas has performed service and maintenance at Whispering Willow Wind Farm – East since the site began operations in 2009.
Alliant Energy owns three other projects using the V82-1.65 MW turbine. In December, Alliant Energy began commercial operations at the Franklin County Wind Farm in Iowa, which includes 60 V82-1.65 MW turbines.
In 2008, Alliant first worked with Vestas to build the Cedar Ridge Wind Farm in Wisconsin, which consists of 41 V82-1.65 MW turbines. Vestas also supplied 122 of these turbines to the Bent Tree Wind Farm in Minnesota, which began commercial operations in 2011.
