Located in Washington County, Illinois, the PSEC is a technologically advanced electric generation facility, 95 percent owned by not-for-profit utilities and rural electric cooperatives. Prairie State's owners are committed to providing clean, reliable and affordable baseload power to the more than 2.5 million families they serve across 180 communities from Missouri to West Virginia.

Prairie State's power plant design incorporates supercritical technology and $1 billion of emissions control equipment; consuming less coal to produce more energy, while achieving one of the best levels of pollution removal in the country. Prairie State also utilizes domestic Illinois coal as its sole power source, derived from its adjacent underground mine, which eliminates the carbon dioxide emissions associated with coal transported from elsewhere. With its combined design efficiencies, Prairie State's carbon footprint is significantly smaller than the typical U.S. coal plant.
