Item 9. Regulation FD Disclosure

Investors Meeting

On February 27-28,  2002, Bob Shapard,  Executive VP and CFO, and Linda Byus, VP
Investor Relations, met with investors and presented the information in Exhibits
99.1 and 99.2.

PECO Energy Company  Customer Choice.

The   Pennsylvania   Public   Utility   Commission's   (PUC's)  Final   Electric
Restructuring  Order  provided for the  phase-in of customer  choice of electric
generation  suppliers  (EGS) and as of  January  1,  2000,  all  customers  were
eligible for customer  choice.  The Final  Restructuring  Order also established
market  share  thresholds  (MST) to promote  competition.  The MST  requirements
provided that, if as of January 1, 2001 and January 1, 2003, respectively,  less
than 35% and 50% of  residential  and commercial  customers  were shopping,  the
number of customers  sufficient  to meet the MST shall be randomly  selected and
assigned to an EGS through a PUC-determined  process.  For residential and small
commercial customers,  the threshold measurement is by number of customers.  For
large  commercial  customers the measurement is by load. On January 1, 2001, the
35% MST  threshold  was met for all customer  classes as a result of  agreements
assigning  customers  to New Power  Company  (New  Power) and Green  Mountain as
providers of last resort  default  service.  During 2002,  PECO  experienced  an
increase in the number of customers  selecting or returning to PECO as their EGS
and at December 31, 2002,  approximately 21% of PECO's  residential load, 10% of
its small  commercial  and  industrial  load and 7% of its large  commercial and
industrial  load  were  purchasing  generation  from an  alternative  generation
supplier.  Customers who purchase  energy from an EGS continue to pay a delivery
charge.  In January 2003,  PECO submitted to the PUC an MST plan to meet the 50%
threshold requirement for its small and large commercial customer classes, which
was  approved on February 6, 2003.  According  to the  approved  plan,  randomly
assigned  customers who participated  will be switched to winning MST bidders as
of their respective meter read dates. On February 21, 2003, Strategic Energy LLC
filed an Application for Stay or Supersedeas with the Pennsylvania  Commonwealth
Court.  In that  Application,  Strategic  Energy  requested  that the Court stay
implementation  on the MST auction  pending  Court review of whether the process
used to develop the auction was  appropriate.  The Court scheduled oral argument
on the Application for March 18, 2003. On February 24, 2003, the small and large
commercial MST auction was completed.  There were three winning bidders who were
awarded a total of 64,172 small  commercial  customers,  at a clearing  price of
1.25%  off  PECO's  tariffed  rate  GS.  No bids  were  received  for the  small
commercial  renewable auction or the large commercial (GS6) non-interval metered
load auction.  Also in February 2003, PECO filed an MST plan for the residential
customer classes which is pending PUC approval.

In  February  2002,  New Power  notified  PECO of its  intent to  withdraw  from
providing Competitive Default Service (CDS) to approximately 180,000 residential
customers. As a result of that withdrawal,  those CDS customers were returned to
PECO in the second quarter of 2002.  Pursuant to a tariff filing approved by the
PUC, PECO is serving those  returned  customers at the discount  energy rates on
generation  provided  for under the  original  New Power CDS  Agreement  for the
remaining  term of that contract.  Subsequently,  in the second quarter of 2002,
New Power also  advised  PECO it planned to  withdraw  from  serving  all of its
customers  in  Pennsylvania,   including   approximately   15,000  non-CDS  PECO
customers.  These  customers  were  returned to PECO during the third quarter of
2002.
