Invenergy has contracted Infrastructure and Energy Alternatives subsidiary White Construction to build the planned 250MW Sapphire Sky wind farm in the US state Illinois.
The $75m deal will see White Construction provide engineering and construction of 64 turbines and nearly 32km of private-land access roads.
Work started on the project during the fourth quarter of 2021, with targeted completion by the fourth quarter of this year.
The development is expected to create nearly 300 new jobs in Illinois during the period of construction.
Infrastructure and Energy Alternatives chief executive JP Roehm said: “Invenergy is a valued, long-term partner of IEA, a company whose commitment to building sustainable energy solutions of scale closely aligns with our vision and values.
