Illinois stands as a national leader in nuclear energy production, operating the highest number of nuclear reactors within any single state in the union. This substantial infrastructure forms the backbone of the region's energy security, providing a steady source of low-carbon electricity to homes and businesses. Understanding the scope and scale of these facilities is essential for grasping the state's energy landscape and its contribution to broader national grid stability.
Current Reactor Inventory and Capacity
The state is home to six active nuclear power plants, which collectively house eleven operational reactors. These facilities are strategically located along major waterways, primarily the Illinois River and the Mississippi River, to leverage water for cooling purposes. The combined capacity of these reactors generates approximately 50% of the state's total electricity, making nuclear energy the dominant power source in Illinois and significantly reducing reliance on fossil fuels for baseload power.

Economic and Environmental Impact
These six plants support thousands of high-skilled jobs across the state, from engineering and maintenance to administrative and security roles. The consistent output of these reactors helps keep energy prices stable and predictable for consumers. Environmentally, the operation of these facilities prevents millions of tons of carbon dioxide emissions annually, playing a crucial role in Illinois's efforts to meet its climate goals and improve air quality.
Unit-Level Breakdown of Reactors
To understand the total of eleven reactors, one must look at the individual units housed within the six plants. Each plant operates one or more reactor buildings, each containing a distinct reactor core that generates heat to produce steam. The following table outlines the specific units and their respective capacities:
