The AES Corporation                                )            File No. 70-9779


            Certificate Pursuant to Rule 24 and Release No. 35-27363
              Under the Public Utility Holding Company Act of 1935


                  On March 23, 2001, the Securities and Exchange Commission
("SEC") issued an order, Release No. 35-27363 in File No. 70-9779 ("Exemption
Order"), granting an exemption under Section 3(a) of the Public Utility Holding
Company Act of 1935, as amended, to The AES Corporation ("AES") in relation to
its proposed acquisition of IPALCO Enterprises, Inc. ("IPALCO"), which has a
public-utility subsidiary company, Indianapolis Power & Light Company ("IPL").
The Exemption Order required AES to file certain certificates (as described in
the Exemption Order) under Rule 24 within 60 days of the close of each calendar
quarter for a period of two years beginning March 31, 2001 and every six months
thereafter. A certificate complying with the Exemption Order is set forth below
(as an attachment) for the period ending March 31, 2003.

                  AES hereby notifies the SEC that effective January 31, 2003 it
sold all of its interests in CILCORP, Inc. ("CILCORP"), including CILCORP's
public-utility subsidiary company, Central Illinois Light Company ("CILCO"). In
accordance with the Exemption Order, AES no longer is including in this
certificate information concerning CILCORP and CILCO. As required by the
Commission's order in Release No. 35-27063, File No. 70-9465, AES has filed with
the SEC periodic certificates with respect of AES' acquisition of CILCORP.
Because of AES' sale of CILCORP, AES intends to file no further certificates in
File No. 70-9465.

(1)   In accordance with the analysis used in the order requiring filing of this
certificate, the AES line items in this table are calculated on a proportional
consolidation basis whereby AES' subsidiaries are included by multiplying each
applicable line item from the statement of operations or balance sheet, as
applicable, of each AES subsidiary times AES' percentage ownership interest in
such subsidiary. The numbers presented for AES in this table exclude CILCO,
which AES sold during the first quarter of 2003.

(2)   Gross business revenues (utility and non-utility) of
IPALCO combined as a percentage of total gross business revenues (including
IPALCO/IPL, utility and non-utility) of AES.

IPALCO's electric revenues are allocated between electric generation and
electric transmission and distribution activities according to utility rate
base. AES generation revenues are derived from the total generation revenues
earned by AES subsidiaries times the percentage ownership interest of AES in
those subsidiaries.

There has been no change in the amount of generation capacity owned by IPALCO
and a 708 MW decrease in the amount of generation capacity owned by AES
(excluding IPALCO) from 39,286 MW to 38,578 MW since December 31, 2002. There
has been a 1% increase in the total revenues earned from the capacity owned by
AES and IPALCO in the 12-month period ended March 31, 2003 compared with the
12-month period ended December 31, 2002. The percentage of the total revenues
derived from the generation capacity owned by IPALCO has increased from 13% to
14%.(1)

IPALCO's electric revenues are allocated between electric generation and
electric transmission and distribution activities according to utility rate
base. AES transmission and distribution revenues are derived from the total
revenues earned by AES transmission and distribution subsidiaries by multiplying
these revenues by the percentage ownership interest of AES in those
subsidiaries.

The total transmission and distribution assets owned by AES and IPALCO have
decreased since December 31, 2002. IPALCO's transmission and distribution assets
have increased while the revenues derived from such assets have increased since
December 31, 2002. AES' transmission and distribution assets have decreased and
the revenues derived from such assets have decreased since December 31, 2002.
IPALCO's percentage of the total transmission and distribution assets has
increased from 21% to 23%, and IPALCO's percentage of the total revenues from
such assets has increased from 6% to 7% for the 12-month period ending March 31,
2003 compared to the 12-month period ending December 31, 2002.(1)

------------------
(1)   This evaluation excludes the transmission and distribution assets and
revenues of CILCO, which AES sold during the first quarter of 2003. CILCO's
electric transmission and distribution and gas distribution assets as of
December 31, 2002 were valued at $793 million; revenues associated with these
assets for the twelve months ending December 31, 2002 were $446 million.
IPALCO's percentage of AES' total transmission and distribution assets
(including CILCO) previously was reported as 19% as of December 31, 2002.
