KENNETT SQUARE, Pa., Jan. 27, 2014 /PRNewswire/ --Exelon Generation's 10
nuclear power plants in Illinois, Pennsylvania and New Jersey produced 134
million net megawatt-hours of electricity in 2013, the highest annual
production ever for the nation's largest operator of commercial nuclear

The new generation record exceeded the previous record, set in 2007 by the
same plants, by 1.6 million megawatt-hours. A megawatt-hour is a million
watts flowing for an hour. The 2013 total is enough electricity to power 15
million typical U.S. homes uninterrupted through the year.

The Exelon fleet last year operated at a 94.1 percent capacity factor, a
measure of reliability. The industry average capacity factor in 2012, the
latest year for which figures are available, was 89.1 percent. Capacity factor
refers to amount of electricity actually produced compared with the
theoretical maximum possible.

Exelon's nuclear plants sustained reliability momentum into 2014 as heavy
snow, ice and record low temperatures plagued much of the country. The fleet
operated continuously during that period. Nuclear energy is by far the largest
clean energy source and the only one that can produce large amounts of
electricity around the clock through severe weather.

Exelon's 17 nuclear reactors represent approximately 20 percent of the
nation's nuclear power capacity.

Exelon Corporation (NYSE: EXC) is the nation's leading competitive energy
provider, with 2012 revenues of approximately $23.5 billion. Headquartered in
Chicago, Exelon has operations and business activities in 47 states, the
District of Columbia and Canada. Exelon is one of the largest competitive U.S.
power generators, with approximately 35,000 megawatts of owned capacity
comprising one of the nation's cleanest and lowest-cost power generation
fleets. The company's Constellation business unit provides energy products and
services to approximately 100,000 business and public sector customers and
approximately 1 million residential customers. Exelon's utilities deliver
electricity and natural gas to more than 6.6 million customers in central
