LaSalle County Generating Station

Nuclear: An Ideal Foundation for Our Clean Energy Future

Located in Marseilles, Illinois, LaSalle County Generating Station's two nuclear reactors can produce up to 2,320 megawatts (MW) of zero-emissions energy, enough carbon-free electricity to power the equivalent of more than 1.7 million homes. The station's 2,058-acre man-made cooling lake is a popular fishery managed by the Illinois Department of Natural Resources.
