Project Facts

The boilers were originally designed for another project and were partially fabricated when that project was canceled.
The design of these boilers was then modified to adapt to the requirements of the Prairie State Energy Campus project, including a change in fuels from Powder River Basin sub-bituminous coal to Illinois bituminous coal.
The boilers burn coal from a mine adjacent to the power plant.
Electricity produced is dedicated to supply eight Midwestern-based public power utilities serving customers across nine states.
