                             Washington, D.C. 20549

   In the Matter of                                              CERTIFICATE
  Cinergy Corp., et al.                                                OF
   File No. 70-9577                                              NOTIFICATION

  Public Utility Holding Company Act of 1935
            ("PUHCA" or "Act")


         Cinergy Corp., a Delaware corporation and registered holding company
("Cinergy"), hereby submits the following pursuant to rule 24 under the Act and
the Commission's orders dated June 23, 2000 and May 18, 2001 in the above
docket, HCAR Nos. 27190 and 27400 (the "Cinergy Financing Orders"). This
certificate reports activity for the calendar quarter ended June 30, 2004.

         Any capitalized terms used herein but not defined herein have the
respective meanings given in the Cinergy Financing Orders.

1.   Pursuant  to the  "EWG/FUCO  Projects  Limit"  prescribed  in  the  Cinergy
     Financing Orders,  Cinergy's "aggregate  investment" (as used in rule 53(a)
     under  PUHCA)  may not  exceed  the sum of (1) an  amount  equal to 100% of
     Cinergy's  "consolidated  retained  earnings"  (as used in rule 53(a) under
     PUHCA), plus (2)  $2,000,000,000,  excluding any investments subject to the
     Restructuring  Limit.  At June 30,  2004,  (a)  Cinergy  had  "consolidated
     retained  earnings"  of $1,548  million and  therefore a EWG/FUCO  Projects
     Limit of $3,548 million; (b) Cinergy's  "aggregate  investment" pursuant to
     the  EWG/FUCO  Projects  Limit  was  approximately  $841  million;  and (c)
     accordingly,  Cinergy's  remaining  investment  capacity under the EWG/FUCO
     Projects Limit was approximately $2,707 million.

2.   At June 30, 2004, consolidated debt, cumulative preferred stock, and common
     stock equity comprised approximately 57.5%, 0.7%, and 41.8%,  respectively,
     of   Cinergy's   consolidated   capitalization.    (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.)

3.   At June 30, 2004, Cinergy's market-to-book ratio was 183%.

4.   The Cinergy  Financing  Orders  reserved  jurisdiction  over the ability of
     Cinergy to make investments  under the  Restructuring  Limit.  Accordingly,
     there is no activity to report with respect thereto.

5.   For the quarter ended June 30, 2004, Cinergy issued $25.1 million of common
     stock and had a net  increase  of $234  million in notes  payable and other
     short-term obligations; Cinergy issued no new long-term debt securities. At
     June 30, 2004, Cinergy's  unconsolidated  total  capitalization  (excluding
     retained   earnings  and  accumulated  other   comprehensive   income)  was
     approximately $3.53 billion, a net increase of $1.53 billion over Cinergy's
     unconsolidated  total  capitalization  at December 31, 1999,  the benchmark
     used in the Cinergy Financing  Orders,  in which the Commission  authorized
     Cinergy to increase its unconsolidated  total capitalization by $5 billion.
     Guarantees  issued by Cinergy and outstanding at June 30, 2004 totaled $852
     million,  leaving remaining  Cinergy guarantee  authority under the Cinergy
     Financing Orders of approximately $1,148 million.  Finally, Cinergy affirms
     that it has met the applicable terms and conditions as specified in Section
     II of the Cinergy Financing Orders.

6.   Pursuant  to a request  for  confidential  treatment  under rule  104(b) of
     PUHCA, Cinergy is concurrently filing in paper format as Exhibit A, certain
     information concerning new investments for the quarter ended June 30, 2004,
     including  the  aggregate  investment  by  EWG/FUCO  Project  and growth in
     retained earnings, along with the year to date June 30, 2004 net income and
     revenues of Cinergy's EWG/FUCO Projects.





                             S I G N A T U R E

         Pursuant to the requirements of PUHCA, the undersigned company has duly
