(Liquidation amount $50 per security) fully and unconditionally guaranteed by,

THE AES CORPORATION

        AES Trust II, a statutory business trust created under the laws of the
state of Delaware, issued and sold 6,000,000 $2.75 Term Convertible Securities,
Series B ("TECONS"), liquidation preference $50 per security in transactions
exempt from the registration requirements of the Securities Act of 1933, as
amended. We filed a registration statement, and printed a prospectus dated March
27, 1998, in order to permit the holders of the TECONS to resell their TECONS in
offerings registered with the Securities and Exchange Commission. On pages 68
and 69 of the prospectus, there is a table that lists:

            (i) each person selling TECONS in connection with the prospectus
                (the "Selling Holders"); and
           (ii) the number of TECONS beneficially owned by each such Selling
                Holder.

This prospectus supplement, which provides supplemental information to that
prospectus, adds certain additional information to the list of Selling Holders:

           1) The number of TECONS to be sold by Donaldson, Lufkin & Jenrette
Securities Corporation is increased by 20,000.

      None of such Selling Holders has a material relationship with AES Trust II
or The AES Corporation except as we have described in the accompanying
prospectus.











THE DATE OF THIS PROSPECTUS SUPPLEMENT IS SEPTEMBER 22, 1999
