         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  orders dated November 2, 2000 and December 8, 2000. This
certificate  reports  activity in File No.  70-9693 for the period April 1, 2002

See Exhibit C 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,
       2002,  Exelon's  "aggregate  investment"  (as defined in rule 53(a) under
       PUHCA)  in all EWGs and  FUCOs  was  approximately  $2,106  million,  and
       accordingly,  at June 30, 2002,  Exelon's remaining  investment  capacity
       under the Modified Rule 53 Test was approximately $1,894 million. At June
       30, 2002, Exelon's  "consolidated  retained earnings" (as defined in rule
       53(a) under the PUHCA) was $1,172 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  Exhibit  A,
       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.

       In the second quarter of 2002,  Exelon  invested in one EWG and committed
       to invest in a second EWG that would count  against the Modified  Rule 53
       Test.  On June 26, 2002,  Genco signed an agreement to acquire  Sithe New
       England Holdings, a subsidiary of Sithe Energies, Inc., for $543 million.
       The parties are seeking FERC and other required  approvals by October 31,
       2002. If approved,  the transaction  could be completed in November 2002.
       In addition,  on June 19, 2002, Genco committed to invest $178 million in
       Southeast Chicago Energy Project, LLC.

       In the second quarter of 2002,  Exelon did not invest or commit to invest
       in a FUCO that would count against the Modified Rule 53 Test.

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.

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, 2002, Exelon's consolidated capitalization ratio was: debt 62%, common equity 35%, and preferred securities of subsidiaries of 3%.
