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 2.3 million homes. The station's 2,058-acre man-made cooling lake is a popular fishery managed by the Illinois Department of Natural Resources.

U.S. nuclear energy facilities are initially licensed to operate for 40 years and a Nuclear Regulatory Commission (NRC) rule allows licensees to apply for extensions of up to 20 years after the initial 40-year term. Constellation submitted a license renewal application for this facility to the U.S. Nuclear Regulatory Commission (NRC), which was approved on October 19, 2016. With license renewal complete, LaSalle Generating Station Unit 1 is licensed through 2042, and Unit 2 is licensed through 2043.

Safety is Constellation’s first and most critical obligation. Nuclear power plants are among the best-protected private sector facilities in America, with monitoring and inspections by plant owners, local officials, and the federal government.
