CORDOVA, Ill. - Operators at Quad Cities Generating Station declared an "Alert" at 1:40 p.m. CT today, after smoke was observed in one of the plant's electrical systems.
The station is in the process of evaluating exiting the Alert status.
The plant is stable and is shutdown. There is no impact to public health or safety or to plant personnel. Exelon's technical experts are looking into the cause of the smoke.
