CORDOVA, Ill. (AP) — Exelon Generation says it has formally notified a grid operator of its plans to retire the Quad-Cities Generating Station, one of two Illinois nuclear plants it intends to shut down.

The Quad-City Times reports that the step announced Thursday is one of several procedural notifications Exelon has to make before closing the station in Cordova and another in Clinton.

The company announced on June 2 that it planned to close the plants after the state Legislature failed to approve a financial-support plan.

Exelon has already notified the Nuclear Regulatory Commission.

Exelon President and CEO Chris Crane said in a news release that the company will “continue to work with all stakeholders to ensure the retirement of these plants is carried out responsibly, safely and with consideration to the employees.”
