CORDOVA, Ill. (May 31, 2009) - Quad Cities Generating Station Unit 1 returned to service shortly after midnight today following the completion of an outage to repair two valves on Unit 1.
The unit, which had been placed back in service on May 24 following the successful completion of a scheduled refueling outage, was subsequently taken offline on May 25.
While performing routine surveillances following the refueling outage, workers identified two valves that were not operating as designed. The valves, which had not been worked on during the refueling outage, cannot be repaired while the unit is operating. While the unit was offline, operators also performed maintenance work on other systems.
The work was done to ensure the continued safe, reliable production of low-carbon electricity and did not affect the supply of electricity to those living in the area.
Quad Cities Generating Station is located in Rock Island County, five miles north of Cordova, IL. With both units at full power, the station can produce more than 1700 net megawatts of electricity, which is enough electricity to power more than 1.5 million homes.
