Duke Energy Renewables will build the 200MW Frontier Windpower project in Oklahoma, US, with operations planned to begin in 2016.
To be developed in Kay County to the east of Blackwell, the wind farm will have the capacity to meet the power requirements of around 60,000 US households.
Energy output from the facility will be supplied to City Utilities of Springfield, Missouri under a 22-year power purchase agreement (PPA).
The project raises Duke Energy Renewables’ wind power portfolio in the country to over 2GW, and is the first green energy project for the company in Oklahoma.
Duke Energy commercial portfolio president Greg Wolf said: "We’re investing heavily in renewable energy, and surpassing 2,000MW of wind power is a significant accomplishment for our company.
"The facility will help City Utilities meet its renewable energy goals while creating economic development opportunities for Kay County."
Wanzek Construction will be responsible for setting up the project for which Amshore US Wind will offer development support.
Construction works for the development are expected to speed up in the first quarter of 2016 in order to keep up with its scheduled commissioning date.
The wind power project will be featuring 61 of Vestas’ V126-3.3 MW wind turbine models.
Vestas US and Canada sales and service president Chris Brown said: "By choosing the V126-3.3 MW turbine for the Frontier wind site, the order also showcases our product portfolio’s great flexibility across all wind sites, as the model provides highly competitive cost of energy in a traditional 2-MW turbine market."
