Onshore Wind - US

Historically, Mainstream developed onshore wind projects.  The Shady Oaks (110 MW) project in Illinois, was developed by Mainstream.  In 2009, it partnered with Goldwind USA to participate in the Illinois Power Agency’s competitive bidding process.

The project was successful and subsequently entered a 20-year inflation indexed power purchase agreement with the largest electric utility in the state of Illinois, Commonwealth Edison. In 2011, Goldwind acquired the wind plant from Mainstream.

Mainstream sold its Green River 1 & 2 (375 MW) project at the development stage.
