Project History
Mackinaw Solar represents a total capital investment of approximately $400 million and is expected to become operational in 2029, with a 30-year life cycle from commercial operation. This project will help advance Illinois’ ambitious climate goals by injecting a significant amount of renewable electric power into the grid, while generating new tax payments that will provide Tazewell County with millions of additional dollars, without requiring additional county services.
