File No. 70-9693                                              NOTIFICATION

Public Utility Holding Company Act of 1935 (PUHCA)

     Exelon  Corporation,  a Pennsylvania  corporation  and  registered  holding
company  (Exelon),  hereby  submits the following  Certificate  of  Notification
pursuant  to Rule  24.  This  filing  is made  pursuant  to  Exelon's  Form  U-1
Application-Declaration, as amended (the "Financing U-1") and the Securities and
Exchange Commission's merger,  financing and investment orders. This certificate
reports  activity  in File No.  70-9693 for the period  October 1, 2003  through
December 31, 2003. Any capitalized terms used herein but not defined herein have
the respective meanings given in the Financing U-1 or the Commission's Orders.

See Exhibit A for Glossary of Defined Terms

1.   Order - A computation in accordance  with rule 53(a) setting forth Exelon's
     "aggregate  investment" in all EWGs and FUCOs, its  "consolidated  retained
     earnings" and a  calculation  of the amount  remaining  under the Requested
     EWG/FUCO Authority.

     Rule  53(a)  provides  that  a  registered   holding  company's   aggregate
     investment  in EWGs and FUCOs may not exceed 50% of its retained  earnings.
     Exelon was granted  partial  relief from this rule pursuant to the December
     8, 2000 Order,  which  provides for a Modified  Rule 53 Test  applicable to
     Exelon's  investments in EWGs and FUCOs of $4,000 million.  At December 31,
     2003,  Exelon's  "aggregate  investment"  (as  defined in rule 53(a)  under
     PUHCA)  in all  EWGs  and  FUCOs  was  approximately  $2,545  million,  and
     accordingly,  at December 31, 2003, Exelon's remaining  investment capacity
     under  the  Modified  Rule 53 Test was  approximately  $1,455  million.  At
     December 31, 2003, Exelon's "consolidated retained earnings" (as defined in
     rule 53(a) under PUHCA) was $2,245 million.

2.   Order - A breakdown  showing Exelon's  aggregate  investment in each EWG or
     FUCO counting against the Requested EWG/FUCO Authority.

     Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA,  Exelon is  concurrently  filing in paper  format as  Attachment  1,
     certain  information   concerning  the  aggregate  investment  by  EWG/FUCO
     Project.

3.   Order  -  Identification  of any  new  EWG or  FUCO  counting  against  the
     requested  EWG/FUCO  Authority in which Exelon has invested or committed to
     invest during the quarter.

     On  December  22,  2003,  Exelon  Generation  Company,  LLC  purchased  the
     remaining 50% interest in AmerGen Energy  Company,  LLC that was indirectly
     owned by BE US  Holdings,  Inc.,  a  subsidiary  of British  Energy plc for
     $276.5  million.  AmerGen  is  now a  wholly  owned  subsidiary  of  Exelon
     Generation  and owns and operates 3 nuclear  generating  facilities  with a
     combined  capacity  of 2,492 MW. The  Clinton  plant is located in Clinton,
     Illinois;  Oyster Creek is located in Forked River,  New Jersey;  and Three
     Mile Island is located in Londonderry Township, Pennsylvania.

     On November 25, 2003,  Generation,  Reservoir Capital Group (Reservoir) and
     Sithe  completed  a series of  transactions  resulting  in  Generation  and
     Reservoir  each  indirectly  owning a 50% interest in Sithe.  The series of
     transactions is described below.  Immediately prior to these  transactions,
     Sithe


                                       1



     was owned 49.9% by Generation,  35.2% by Apollo Energy,  LLC (Apollo),  and
     14.9% by subsidiaries of Marubeni Corporation (Marubeni).

     Entities  controlled by Reservoir  purchased certain Sithe entities holding
     six U.S. generating facilities, each a qualifying facility under the Public
     Utility  Regulatory  Policies Act, in exchange for $37 million ($21 million
     in cash and a $16  million  two-year  note);  and  entities  controlled  by
     Marubeni  purchased all of Sithe's entities and facilities outside of North
     America (other than Sithe Energies  Australia (SEA) of which it purchased a
     49%  interest on November  24, 2003 for  separate  consideration)  for $178
     million.  Marubeni agreed to acquire the remaining 51% of SEA in 90 days if
     a buyer is not found,  although  discussions  regarding  an  extension  are
     ongoing.

     Following  the  sales of the above  entities,  Generation  transferred  its
     wholly owned  subsidiary  that held the Sithe  investment to a newly formed
     holding company.  The subsidiary holding the Sithe investment  acquired the
     remaining  Sithe  interests from Apollo and Marubeni for $612 million using
     proceeds  from  a  $580  million  bridge   financing  and  available  cash.
     Generation  sold a 50% interest in the newly formed holding company for $76
     million to an entity  controlled by Reservoir.  On November 26, 2003, Sithe
     distributed  $580  million  of  available  cash to its  parent,  which then
     utilized the distributed funds to repay the bridge financing.

     In  connection  with  this  transaction,  Generation  recorded  obligations
     related to $39 million of guarantees in accordance with FASB Interpretation
     (FIN) No. 45,  "Guarantor's  Accounting  and  Disclosure  Requirements  for
     Guarantees,  Including Indirect  Guarantees of Indebtedness to Others" (FIN
     No. 45).  These  guarantees  were issued to protect  Reservoir  from credit
     exposure of certain counter-parties through 2015 and other indemnities.  In
     determining  the  value of the FIN 45  guarantees,  Generation  utilized  a
     probabilistic  model to assess the  possibilities  of future payments under
     the indemnifications.

     Both  Generation and  Reservoir's 50% interests in Sithe are subject to put
     and call  options  that could  result in either party owning 100% of Sithe.
     While  Generation's  intent is to fully divest Sithe, the timing of the put
     and call options vary by acquirer and can extend  through  March 2006.  The
     pricing of the put and call options is dependent on numerous factors,  such
     as the acquirer,  date of acquisition and assets owned by Sithe at the time
     of  exercise.  Any  closing  under  either  the  put  or  call  options  is
     conditioned upon obtaining state and Federal regulatory approvals.

     Based on Generation's interpretation of FASB Interpretation No. 46 (revised
     December  2003),  "Consolidation  of Variable  Interest  Entities" (FIN No.
     46-R), it is reasonably  possible that Generation will consolidate Sithe as
     of March 31, 2004. The book value of  Generation's  investment in Sithe was
     $47 million at December 31, 2003.


4.   Order -  Analysis  of the growth in  consolidated  retained  earnings  that
     segregates  total earnings growth of EWGs and FUCOs from that  attributable
     to other subsidiaries of Exelon.

     Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA, Exelon is concurrently filing in paper format as Attachment 1, total
     earnings growth by EWG and FUCO project in the fourth quarter, 2003.

5.   Order - A statement  of  revenues  and net income for each EWG and FUCO for
     the twelve months ending as of that quarter.

     Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA,  Exelon is concurrently  filing in paper format as Attachment 1, net

6.   Order - Consolidated  capitalization  ratios of Exelon,  with  consolidated
     debt to include all short-term  debt and  nonrecourse  debt of all EWGs and

     At December 31, 2003, Exelon's consolidated  capitalization ratio was: debt
     63%,  common  equity 35%, and  short-tem  debt of 2%. (For these  purposes,
     "consolidated debt" means all long-term debt, long-term debt due within one
     year,  notes  payable  and  other  short-term  obligations,  including  any
     short-term debt and non-recourse debt of EWG/FUCO  Projects,  to the extent
     normally consolidated under applicable financial reporting rules).

7.   Order - A table  showing,  as of the end of the  quarter,  the  dollar  and

     In the fourth quarter of 2003,  Genco entered into a forward  starting swap
     to hedge interest rate exposure associated with future debt issuances.  The
     swap is designated as a cash flow hedge in that it attempts to minimize the
     variability of the future interest  expense  associated with changes in the
     3-month  LIBOR  rate.  A  table   summarizing  the  forward  starting  swap
     transaction  that was  entered  into in the fourth  quarter  is below.  The
     transaction was unwound prior to the associated debt issuance.
