             NRC Approves 20-Year License Extension for Peach Bottom

KENNETT SQUARE,  Pa. - The U.S. Nuclear  Regulatory  Commission  announced today
that it has approved a 20-year  extension of the  operating  licenses for Exelon
Nuclear's Peach Bottom Atomic Power Station in York County, Pa.

Exelon Nuclear is the largest  operator of commercial  nuclear power stations in
the nation and third largest worldwide.  Peach Bottom's two generating units are
the first of Exelon Nuclear's 17 reactors to receive extended licenses.  The NRC
has renewed the  licenses of 14 other U.S.  nuclear  reactors  and is  reviewing
applications for 14 more.

The original  40-year  license for Peach Bottom Unit 2 was to expire in 2013. It
has been  extended  to 2033.  The Unit 3  license  was to  expire in 2014 and is
extended to 2034. Peach Bottom Unit 1, an early gas-cooled prototype reactor, is
no longer in operation.

"This  decision  means Peach Bottom will continue to deliver  safe,  carbon-free
electricity  to more than two million  households  on the Atlantic  seaboard for
another two decades,"  said Exelon Nuclear  President and Chief Nuclear  Officer
Jack  Skolds.  "And we are  doing it  without  turning  a spade of  earth.  This
contributes  mightily to America's  energy  independence and to the mid-Atlantic
region's inventory of safe, inexpensive electricity."

Peach Bottom's local economic  impact is significant  and will continue as well.
The station employs about 700 people,  with an annual payroll of $57 million. It
pays about $1 million  annually in property  taxes and spends $10 million a year
in purchases of local goods and services.

"Peach Bottom's  history of safe operation is the primary reason we can continue
to produce  power over the next 20 years,"  said station  Vice  President  Rusty
West.  "Safe  operation is the lynchpin  behind  license  extension,  which is a
long-term  investment in our employees,  in the communities  around Peach Bottom
and in our company.  We're very happy that we will continue to be an active part
of our communities for many years to come."






The station also generates low-cost electricity.  In 2002, Peach Bottom produced
power for about three-fourths of the average cost of coal-generated  electricity
and one-fourth the average cost of electricity generated from natural gas.

Peach Bottom's  license renewal program began in 1999 and required four years of
extensive engineering, safety and environmental analysis, NRC review, and public
input.  Engineers  reviewed  more  than  100  plant  systems  and  about  40,000
components  to ensure the two units are capable of running for an  additional 20
years. The project cost about $14 million to complete.

"The safety review  determined  that Peach Bottom has solid programs in place to
provide for the continued  safe and reliable  operation and  maintenance  of the
plant," West said. "The  environmental  review concluded that any  environmental
impacts from extending the license would be small."

As part of the review,  the NRC held public  meetings  and verified the analysis
with  county,  state  and  federal  agencies.   Experts  from  national  nuclear
laboratories,  environmental  agencies,  historical  preservation  societies and
others were consulted.

Peach Bottom Atomic Power Station is in Peach Bottom Township of York County and
has two General  Electric  boiling water  reactors that produce a total of 2,274
net megawatts.  Unit 2 (1,148 net megawatts) began commercial  operation on July
5, 1974.  Unit 3 (1,126 net megawatts)  began  commercial  operation on Dec. 23,
1974. A megawatt is a million watts.
