Illinois Nuclear Plants Transition Ownership From ComEd to Constellation

The Government Services Committee Meeting held on July 28, 2025, by the City Council of Saint Charles, Illinois, featured discussions primarily focused on the state's nuclear energy landscape. A key point of conversation revolved around the ownership and operational status of nuclear plants in Illinois, which are predominantly owned by Constellation Energy.

During the meeting, a council member noted that Illinois has the highest number of nuclear plants in the United States. These facilities were originally part of ComEd before being acquired by Exelon, which later spun off Constellation as a separate entity. The discussion highlighted the historical context of these plants and their significance in the state's energy portfolio.

Another topic raised was the licensing status of the nuclear plants, with questions about when these licenses are set to expire. However, specific details regarding the expiration dates were not available during the meeting.

Overall, the discussions underscored the importance of nuclear energy in Illinois and the ongoing interest in understanding its regulatory framework and future implications for the state's energy strategy. The committee's inquiries reflect a broader concern about energy management and sustainability in the region.
