Duke Energy will build the Frontier Windpower Project at a site in Kay County, northern Oklahoma, central US. It is Duke's first wind project in the state.
The power produced by the project will be sold to City Utilities of Springfield, in neighbouring Missouri, in a 22-year deal.
"We are excited to be working with the community and local landowners as we get our first project in this wind-rich state underway. The facility will help City Utilities meet its renewable energy goals while creating economic development opportunities for Kay County," said Duke's commercial portfolio president, Greg Wolf.
Construction will begin in early 2016 with the project set for completion by the end of that year.
A total of 61 Vestas V126-3.3MW turbines will be installed at the site.
"Historically, Oklahoma has been 2MW territory, but this order once again emphasizes the versatility of our product portfolio and shows that we can draw from both our 2MW and 3MW platforms to select exactly the right turbine to meet our customers' needs," said Vestas president of sales and service division in the US, Chris Brown.
