Prairie State Project

The Prairie State Energy Campus in Washington County, Illinois is a technologically advanced electric generation facility, 95% owned by eight non-profit utilities who are committed to providing clean, reliable and affordable baseload power to hundreds of local communities in the Midwest and Mid-Atlantic regions.  Its combined design efficiencies mean Prairie State will significantly improve our industry’s environmental profile by displacing existing, less-efficient power plants – it will produce nearly 2.5 million fewer tons of carbon dioxide per year than the electricity generation it is replacing.
