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  orders dated November 2, 2000 and December 8, 2000. This
certificate  reports  activity in File No.  70-9693 for the period April 1, 2001
through June 30, 2001. Any capitalized  terms used herein but not defined herein
have the  respective  meanings  given in the Financing  U-1 or the  Commission's
Orders.

1.   As determined  pursuant to the December 8, 2000 Order, the Modified Rule 53
     Test  applicable  to  Exelon's  investments  in EWGs and FUCOs is  $4,000.0
     million. At June 30, 2001,  Exelon's "aggregate  investment" (as defined in
     rule  53(a)  under  PUHCA) in all EWGs and FUCOs was  approximately  $744.0
     million,  and accordingly,  at June 30, 2001, Exelon's remaining investment
     capacity  under  the  Modified  Rule 53  Test  was  approximately  $3,256.0
     million.  At June 30, 2001, Exelon's  "consolidated  retained earnings" (as
     defined in rule 53(a) under the PUHCA) was approximately $755.0 million.

     Note: In its quarterly Rule 24  certificate  for the first quarter of 2001,
     filed May 30, 2001,  Exelon reported an "aggregate  investment" in EWGs and
     FUCOs of $770 million.  This number is in error,  as it included  growth in
     retained  earnings  and  not any  additional  investments.  The  "aggregate
     investment" in EWGs and FUCOs has not changed from the amount of "aggregate
     investment" initially disclosed, $744 million.

2.   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.   At June 30, 2001, Exelon's consolidated capitalization ratio was: debt 65%,
     common equity 32%, and preferred  securities  of  subsidiaries  of 3%. (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).

4.   At June 30, 2001,  the  market-to-book  ratio of Exelon's  common stock was
     2.76.

5.   In the second quarter of 2001, Exelon did not invest or commit to invest in
     an EWG or FUCO that would count against the Modified Rule 53 Test.

6.   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  aggregate  investment  by EWG and FUCO Project and
     related growth in retained earnings.

7.   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 aggregate investment by EWG/FUCO Project, net income
     and revenues of Exelon's EWG and FUCO Projects.

8.   Sale of any Common Stock or Preferred  Securities  issued by Exelon  during
     the second quarter of 2001, and the purchase price per share and the market
     price per share at the date of the agreement of sale.
