LaSalle County Nuclear Generating Station
[edit on Wikidata]
LaSalle County Nuclear Generating Station, located in Brookfield Township, LaSalle County, Illinois, near Marseilles, 11 miles (18 km) southeast of Ottawa, serves Chicago and Northern Illinois with electricity. The plant is owned and operated by Constellation Energy following separation from Exelon Corporation in 2022. Its Units 1 and 2 began commercial operation in October 1982,[1] and October 1984,[1] respectively.
It has two General Electric boiling water reactors. LaSalle's Unit 1 and Unit 2 together produce 2,320 megawatts, which is enough electricity for the needs of 2.3 million American homes.[1]
Instead of cooling towers, the station has a 2,058-acre (833 ha) man-made cooling lake, which is also a popular fishery — LaSalle Lake State Fish and Wildlife Area — managed by the Illinois Department of Natural Resources.[1]
