Exelon to close Clinton and Quad Cities nuclear plants

Exelon said Thursday it will move ahead with plans to shutter the Clinton and Quad Cities nuclear plants, blaming the lack of progress on Illinois energy legislation.

The company, the parent of Chicago-area utilities provider ComEd, said the Clinton Power Station will close June 1, 2017, and the Quad Cities Generating Station in Cordova will close June 1, 2018. Both plants, the company said, have lost a combined $800 million in the past seven years, despite being “two of the best-performing plants,” the company said in a statement.

The move comes after the Illinois General Assembly adjourned earlier this week without acting on the legislation known as the Next Generation Energy Plan, which Exelon said would have helped save the nuclear plants.

“We have worked for several years to find a sustainable path forward in consultation with federal regulators, market operators, state policymakers, plant community leaders, labor and business leaders as well as environmental groups and other stakeholders,” said CEO Chris Crane in a news release. “Unfortunately, legislation was not passed, and now we are forced to retire the plants.”
