Exelon Generation Kicks Off Fall Maintenance Work at Illinois Nuclear Units, Adding 4,200 Temporary Jobs

BYRON, Ill.  — The city of Byron’s population jumped by a third this week as more than 1,400 temporary workers traveled to the area in support of Byron Generating Station’s annual refueling outage. Operators removed Unit 1 from service to inspect, refuel and upgrade the nuclear energy plant to ensure continued safety and reliability during the winter months ahead.

Byron’s refueling and maintenance outage is one of three planned this fall, including a Unit 2 outage at Braidwood Generating Station in Braceville, Ill., and a Unit 3 outage at Dresden Generating Station in Morris, Ill. These outages will add 4,200 temporary jobs and infuse millions of dollars into the Illinois economy.

"Exelon’s fall outages support more than a thousand electricians, pipe fitters, welders, laborers and other contractors,” said Stacy McCaskill, director, Illinois Small Business Development Center (SBDC) at Sauk Valley Community College. “This influx of people and purchasing makes small-town businesses thrive. We are so thankful for Exelon's support of our Illinois SBDC so that we can continue helping small business serve the needs of Exelon's hardworking employees.”

“The extra workers in town for the outage give our businesses an added boost to their bottom line,” said Oregon Mayor Ken Williams. “The timing works out very well with the outage lasting through September and then our annual ‘Autumn On Parade’ taking place Oct. 6-7. We hope many more visitors can enjoy our scenic area as we transition into fall.”

During the outage, the Unit 1 cooling tower will not produce any water vapor cloud. This is normal when a unit is taken offline.
Byron’s Unit 2 reactor will continue to supply carbon-free electricity to customers during the Unit 1 outage. With both units at full power, the site produces almost 2,500 megawatts, enough electricity to power more than 2 million average American homes. Byron Generating Station is in Ogle County, Ill., about 25 miles southwest of Rockford.
