The Clinton Power Station is a 1,070 MW boiling water reactor located near Clinton, Illinois. Construction began in 1976 and the plant began licensed operations in 1987. The Clinton reactor is licensed to operate until 2026. Exelon plans to submit a license renewal application in the first quarter of 2021.

Operating Environment

As natural gas electricity generation has placed competitive pressures on electricity rates, Illinois voted (in 2016) to subsidize Exelon with 1¢/kWh or approximately $240 million per year to keep Clinton and Quad Cities Nuclear Generating Station open for at least 10 years.


The Clinton plant is located within DeWitt County, Illinois. As of 2016:

  • Population: 16,000
  • Per Capita Annual Income: $45,000
  • Unemployment rate (not seasonally adjusted): 4.6%

The annual payroll at the Clinton Power Station is approximately $63M and in 2017 the plant contributed $13M in property tax payments.
