Site description

The Prairie State Energy Campus is a 1,600 MW coal-fired power plant that is owned by nine different power utilities, with majority ownership belonging to American Electric Power. When the second unit began operations in November 2012, Prairie became the largest US coal-fired plant built in the last 30 years. Prairie State is built on earthquake fault lines, between the Wabash seismic and New Madrid fault lines.
