The turbine manufacturer has purchased 80 acres to the east of the facility, which is located near Greeley, according to reports. The deal cost $2.5million.
The Coloradoan quoted a representative from the company who sold the property to Vestas. He said the land would be used to store blades for a "recent order".
He added that although the property was zoned for agriculture usage, Greeley authorities had given Vestas a temporary industrial usage permit.
In July, New York-based developer Terra-Gen Power signed a 570MW order with Vestas for 190 V90-3.0 MW turbines, which would be made at the Windsor plant. It is the largest order Vestas has received for a single site.
