("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.

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.
