The station has a single generation II General Electric Boiling Water Reactor. The present reactor operating license was issued April 17, 1987, and will expire September 29, 2026. Plans for a second reactor were shelved. Exelon, the owner and operator of the present reactor, announced plans to permanently close the power station in June 2017, due to the plants struggles to compete economically in wholesale markets, resulting in a loss of millions of dollars in recent years. The plans for closure were canceled, however, when the Illinois State Legislature passed and the Illinois Governor signed SB 2814, The Future Energy Jobs Bill. The legislation provides Zero Emission Credits for the plants' -free electricity. The consequences of continued operation include saving 4,200 jobs and the annual generation of 22 billion kWhs of -free energy.
