Cordova, Illinois – Quad Cities Unit 1 automatically shut down at 3:58 a.m. CST today during a scheduled maintenance activity in the plant’s condenser. The condenser helps efficiently turn steam into water on the non-nuclear side of the plant.

The automatic shutdown occurred with all plant equipment operating as designed.  Exelon personnel  are reviewing the activity that led to the shutdown to determine its cause and to return the plant to service in an efficient manner.

Quad Cities Unit 2 continues to operate at full power and there was no impact to the Exelon customers as a result of Unit 1 coming offline.

Quad Cities Generating Station is located on the banks of the Mississippi River in Cordova, Illinois. With both units running at full power, Quad Cities generates electricity to power more than 1 million average American homes.
