Braidwood Nuclear Generating Station

Braidwood Generating Station is located in Will County in northeastern Illinois, U.S. The nuclear power plant serves Chicago and northern Illinois with electricity. The plant was originally built by Commonwealth Edison company, and subsequently transferred to Com Ed's parent company, Exelon Corporation. Following Exelon's spin-off of their Generation company, the station was transferred to Constellation Energy. This station has two Westinghouse pressurized water reactors. Unit #1 came online in July 1987. Unit #2 came online in May 1988. The units were licensed by the Nuclear Regulatory Commission to operate until 2026 and 2027, then granted extended licenses until 2046 and 2047. Each unit has received two power uprates during their lifetime, the first in May 2001 for 175.6 MWt and the second in February 2014 for 58.4 MWt. The power uprates at Braidwood granted in 2001 make it the largest nuclear plant in the state, generating a net total of 2,386 megawatts. However the three largest Illinois nuclear power plants are nearly equal in generating capability as LaSalle County Nuclear Generating Station is only 2 MW less in capacity than Braidwood and Byron Nuclear Generating Station is only 4 MW less than LaSalle.
