Exelon Generation’s Illinois Nuclear Facilities Refueled and Ready to Power Seven Million Homes This Winter

Well executed refueling outages, robust winter readiness efforts make
nuclear the most reliable source of year-round power

WARRENVILLE, Ill.–(BUSINESS WIRE)–Exelon Generation’s Illinois nuclear facilities operated reliably this
summer and are now refueled and ready to take on winter weather. Coming
off one of their best seasons ever for outage performance, all six
Exelon Generation Illinois nuclear stations completed comprehensive
winter readiness activities this year to make them even more reliable
and resilient as temperatures drop and demand for power rises.

“We prepare for winter all year long,” said Bryan Hanson, Exelon
Generation’s Chief Nuclear Officer. “We executed our 2017 refueling
outages flawlessly and successfully completed a host of ‘winter
readiness’ maintenance activities to keep our fleet of nuclear power
facilities online when they are needed most.”

Exelon Generation’s Illinois fleet of 11 reactors at six locations are
operating more than 93.5 percent of the time. This metric, called
capacity factor, is a key industry performance indicator and Exelon
Generation is ready to continue this record of outstanding performance
this winter. No other large-scale carbon-free power source comes close
to matching this level of reliability.

Exelon Generation workers spend months ensuring that backup generators
and redundant equipment is ready for inclement weather. This fall,
operators and maintenance personnel inspected freeze protection systems,
tested electrical equipment, and properly aligned plant systems to
prepare all Exelon Generation facilities for sub-zero temperatures, icy
conditions and heavy snowfall. These efforts are in addition to the many
equipment upgrades performed during refueling outages.
