The Byron Nuclear Generating Station is a nuclear power plant located in Ogle County, Illinois, 2 miles (3.2 km) east of the Rock River. The reactor buildings were constructed by Commonwealth Edison and house two Westinghouse Four-Loop[2] pressurized water reactors, Unit 1 and Unit 2, which began operation in September 1985 and August 1987 respectively. The plant is owned and operated by Constellation Energy.

The plant provides electricity to northern Illinois and the city of Chicago. In 2005 it generated on average about 2,450 MWe, enough power to supply about 2 million average American homes. The station employs over 600 people, mostly from Ogle and Winnebago counties, and features two prominent 495-foot (151 m) cooling towers.

The Byron plant has been subject to some controversy with respect to a lawsuit in 1981 with concerns over tritium contamination in groundwater. Tritium contamination at Byron and other Illinois nuclear power plants led the state of Illinois to pass legislation requiring plants to report such contamination to the state within 24 hours.
