PSGC Power Plant Update

Marissa, IL – Prairie State Energy Campus’s power plant is comprised of two 800-MW units. Unit 1 is in startup and will be producing power for its nine Owners today. On Saturday morning, while Prairie State was taking Unit 2 offline for a scheduled maintenance outage, a water storage tank overflowed resulting in an unexpectedly high release of steam and water that damaged the siding and associated equipment. All of the employees and workers on site are safe. No explosion, fire or injuries occurred.
Neither the boiler nor the turbine generator was damaged. The unit will be returned to service after repairs to the storage tank and siding are complete. Unit 2 is expected to be back online and producing power for most of the summer.
“PSGC’s power plant team is committed to maintaining its transparency with its member-Owners and the customers they serve,” said Duncan Kincheloe, PSGC’s interim CEO and President. “The repair schedule will be updated on a regular basis.”
Located in Washington County, Illinois, the Prairie State Energy Campus is a technologically- advanced electric generation facility, utilizing domestic Illinois coal resources to power its 1600 megawatt power plant. Prairie State’s owners, which represent 10 percent of public power, invested more than $1 billion in environmental emissions control equipment, placing Prairie State’s power plant among the top 10 cleanest plants in the nation.
