Coal-Fired Plants in Illinois
Baldwin
Location: IL
Operator: Dynegy
Configuration: 1 X 623 MW, 2 X 635 MW
Operation: 1970-1975
Fuel: subbituminous coal
Boiler supplier: B&W, CE
T/G supplier: WH, GE
EPC: Sargent & Lundy, Baldwin Associates
Quick facts: This plant was originally built for and operated by Illinois Power. As part of this project, a 2,018ac perched cooling lake was built by constructing an 8mi levee on the Kaskaskia River and dredging out a section of bottomland. Most of the lake is maintained by the state and operated as a fishery resource and wildllfe habitat. The plant has two cyclone boiler units with SCR and a tangential boiler which were used for a demonstration of an online boiler and pollution control equipment optimization system developed by NeuCo Inc. The $45mo project cost about $19mn of which 45% was paid by the US Dept of Energy.

Cahokia
Location: IL
Operator: AmerenUE
Configuration: 3 X 30 MW, 1 X 50 MW, 2 X 75 MW
Operation: 1923-1937 (ret 1976)

Boiler supplier: ??
T/G supplier: ??
Quick facts: Cahokia was an early "superpower" plant and at completion was the largest power station in the Mississippi Valley. The brick structure was built on a 52ac site and rested on concrete piles driven to hard gravel 30ft below the river bed of the Mississippi. The 265ft stacks are 21ft in top diameter. Cahokia was the first power plant designed to use pulverized Illinois coal and late in life was converted to oil firing. Twenty-nine submarine cables carried electricity to St. Louis. Union Electric sold the property in 1979.
