Mortenson, a US-based construction firm, has been selected by Xcel Energy to construct the 600MW Rush Creek Wind Project in Colorado, US.
The wind farm will be the largest single-phase wind farm ever built in North America, according to Morteson.
The project, owned and operated by Xcel Energy, will feature 300 turbines and a 134km transmission line near Limon, Colorado. The wind turbines will be provided by Vestas.
Under the contract, Mortenson's wind energy, high voltage transmission and civil groups will provide full engineering, procurement and construction services for the project.
Mortenson said that the project will increase Colorado's wind energy production by more than 20% and generate $180M in landowner lease payments and property tax revenue.
Tim Maag, vice president and general manager at Mortenson's Wind Energy Group, said: "We are pleased to be selected to construct this significant project for Xcel Energy and the state of Colorado. This project is another great example of Xcel's commitment to clean renewable energy."
Engineering design is expected to be complete in April 2017, with construction set to begin in May 2017. The wind farm is expected to create 350 jobs during the construction peak.
The project is set to be operational in October 2018.
