Infrastructure and Energy Alternatives (IEA) has announced that the company has been awarded the Big Sky Repower balance of plant (BOP). Vitol awarded the project to White Construction, a subsidiary of IEA that manages utility-scale renewable energy and heavy civil infrastructure projects.
The award is for the repowering of a 240MW utility-scale wind farm in the Bureau and Lee Counties of Illinois. Work on repowering the Big Sky Wind Farm will begin in August 2021 and is expected to be completed in July 2022. IEA will self-perform all of the engineering, procurement and construction needs of the project, including full decommissioning and foundation removal of five wind turbine generators (WTG) and the repowering of 109 WTGs, including the replacement of nacelles, hubs, blades and adaptor rings. By the end of the construction, it is expected that the project will increase the wind farm’s annual output by approximately 60 percent. The project is valued at approximately $70 million.
