Clinton Power Station

Clinton Power Station

Clinton Power Station, one of Exelon’s newest nuclear power plants, is located in central Illinois about 6 miles east of Clinton, Illinois in DeWitt County.

The nuclear power plant is built on a 14,300-acre site with a 5,000-acre cooling lake formed by a dam built at the convergence of Salt Creek and the North Fork of Salt Creek. Clinton Power Station began operating April 24, 1987 and reached 100% capacity on September 15, 1987.  The unit is capable of generating nearly 1,065 net megawatts (MW), enough electricity to power about 1 million average American homes.

Committed to Safety

Clinton Power Station, like all U.S. nuclear energy facilities, is based on a “defense-in-depth” design, which means there are redundant layers of safety.  There are multiple layers of safety systems to provide water to the reactor core.  These safety systems, and their backup safety systems, are powered by multiple and redundant power sources.  Nuclear energy plants are built with multiple physical barriers, including thick, steel-reinforced concrete walls around the reactor to contain radioactive materials. 

Our employees are personally committed to safety.  They are highly-skilled workers and continually receive training to make our safe work practices even safer.  We have a culture of continuous learning and implement lessons learned from operating experience to continue to operate safe nuclear energy facilities.  Each employee has 100 percent accountability.  We welcome strict, daily oversight by the Nuclear Regulatory Commission (NRC).  We work with the NRC to ensure that all regulations are complied with - and exceeded.

Generating More Low-Carbon Electricity

As part of Exelon 2020, Exelon Nuclear launched a series of planned power uprates across the company's nuclear fleet that will generate additional generation capacity within 8 years without turning a spade of earth. Uprate projects improve the efficiency and increase electricity output of a nuclear generating unit through upgrades to plant equipment. The projects take advantage of new production and measurement technologies, new materials and learning from a half-century of nuclear power operations.

Greening Our Operations

As part of Exelon’s environmental and business strategy, Exelon 2020, the Clinton Power Station has been making energy-efficient improvements where possible.  In 2008, Clinton received silver LEED certification of its energy-efficient administration building. These improvements include a reflective white roof to reduce heat gain, an automated lighting system, natural lighting, high-efficiency lighting in the warehouse and use of paper and plastic disposable plates and cups.

Emergency Planning

Clinton employs a sophisticated emergency response plan to protect public health and safety approved by the Nuclear Regulatory Commission (NRC) and the state of Illinois. The emergency plan includes coordination with local counties, municipalities and school districts.

Supporting the Local Economy

The majority of Clinton’s approximately 700 employees live in DeWitt, McLean, Macon and Champaign counties. During refueling outages, Clinton employs several hundred contractors who boost the local economy during their stay.

Community Involvement

Clinton aims to be a good neighbor and is very active in the local community.

  • Sponsorship.  The power plant sponsors several community events including a series of free summer concerts in Clinton. It also sponsors youth sports teams.
  • Charitable Giving & Volunteering.  Clinton employees give generously to the community through a variety of charitable activities, including the local United Way chapters.  The plant also sponsors blood drives throughout the year, helping local hospitals. The station’s Diversity Committee also runs food, toy and fund drives to support various community groups and agencies.
