Zion Station

Zion Station

Zion Station is a former nuclear generating facility that has been converted into an electrical grid voltage-stabilizing facility. It is located on the western shore of Lake Michigan in the Northeast Illinois community of Zion.

After more than 20 years of operation, Zion's two reactors were permanently shut down on January 15, 1998. Commonwealth Edison, owner of the plant at the time, concluded that the continued operation of Zion Station was not financially feasible and the plant was removed from service.

The site is approximately 50 miles north of Chicago and 42 miles south of Milwaukee. The plant property sits between the northern and southern parts of the Illinois Beach State Park, a 4,000 acre public park that receives thousands of visitors each year.

Future of Zion

The decommissioning of Zion Station began Sept. 1, 2010. The $1 billion, 10-year project will be the largest commercial nuclear plant dismantling ever undertaken in the United States, requiring an average of 200 skilled workers each year, most of them local, and a peak workforce of 400.
