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 April 1, 2003 through June
30,  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 June 30, 2003,  Exelon's  "aggregate  investment" (as defined in rule
        53(a)  under  PUHCA)  in all EWGs and  FUCOs  was  approximately  $2,806
        million,   and  accordingly,   at  June  30,  2003,  Exelon's  remaining
        investment  capacity  under the Modified Rule 53 Test was  approximately
        $1,194  million.  At June  30,  2003,  Exelon's  "consolidated  retained
        earnings" (as defined in rule 53(a) under PUHCA) was $2,150 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 May 29, 2003, Exelon Fossil Holdings, Inc., a wholly owned subsidiary
        of Exelon  Generation,  issued an irrevocable  call notice for the 35.2%
        interest in Sithe  Energies,  Inc. owned by Apollo  Energy,  LLC and the
        14.9% interest owned by subsidiaries of Marubeni Corporation.  The total
        call  price  will be based on the  terms  of the  existing  Put and Call
        Agreement  among the parties,  which we estimate  will be  approximately
        $650  million.  The payment of the call is  anticipated  to occur in the
        fourth quarter of 2003. See Exelon Corporation Form 8-K filed on May 29,
        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 second  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 income and revenues of Exelon's EWG and FUCO Projects for the twelve
        months ended June 30, 2003.

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

        At June 30, 2003, Exelon's  consolidated  capitalization ratio was: debt
        64%, common equity 34%, and preferred  securities of subsidiaries 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
        percentage   components  of  the  capital   structure  of  Exelon  on  a
        consolidated basis and of each Utility Subsidiary.

        Capital Structure of Exelon and its utility  subsidiaries as of June 30,
        2003 are as follows (in millions, except percentage data):
