The Clinton Nuclear Power Plant is located near Clinton, Illinois, USA. The nuclear power station has a General Electric boiling water reactor on a 14,300 acres (57.9 km2) site with an adjacent 5,000 acres (20.2 km2) cooling reservoir, Clinton Lake. Due to inflation and cost overruns, Clinton's final construction cost exceeded $2.6 billion. The power station began service on April 24, 1987 and is currently capable of generating 1,043 MW.

After more than a decade of operation the plant's original owner, Illinois Power, deduced that it was not economical to own and operate only one nuclear generating station. They subsequently sold Clinton Nuclear Power Plant to Exelon Corporation for a more modest price of $40 million dollars, with the purchase including the fuel in the reactor vessel and responsibility of all the radioactive waste in the spent fuel storage pool. The reactor design is of the type called the Generation II reactor. Clinton Nuclear Power Plant is a BWR-6 with a Mark III containment structure. The present reactor operating license was issued April 17, 1987, and will expire September 29, 2026.

The Operator and Owner is the Exelon Corporation.

In September 2003, Exelon submitted an Early Site Permit to place a second reactor at the Clinton site — this was approved March 15, 2007. The Early Site Permit does not actually grant any type of license to begin building a second reactor, although it offers the operator an avenue to begin the approval process leading to construction and operation of an additional power reactor at the site. According to the ESP, the new plant design will be of the AP1000 type, although the ESP does not state what gross wattage has been selected.
