                   CENTERPOINT ENERGY ANNOUNCES REDEMPTION OF
                 2.875 PERCENT CONVERTIBLE SENIOR NOTES DUE 2024
               AND EXTENSION OF PURCHASE OPTION FOR 2.875 PERCENT
                        CONVERTIBLE SENIOR NOTES DUE 2024

     HOUSTON - DECEMBER 21, 2006 - CenterPoint Energy, Inc. (NYSE: CNP) today
announced the planned redemption of all outstanding 2.875 percent Convertible
Senior Notes due 2024 on January 22, 2007 (Redemption Date). The redemption
price will be $1,000 in cash, plus accrued and unpaid interest, including
contingent interest, if any, to the Redemption Date.

     The amount of regular interest that will be payable with respect to the
notes on the Redemption Date is $0.559 per $1,000 principal amount. Pursuant to
the indenture governing the notes, the amount of contingent interest that will
be payable with respect to the notes on the Redemption Date, if any, will be
determined by reference to the average trading price of the notes for the five
business days ending on January 11, 2007.

     The notes, which become convertible upon a call for redemption, are
convertible into cash or, at CenterPoint Energy's option, a combination of cash
and shares of CenterPoint Energy's common stock. The current conversion rate of
the notes is 79.8969 shares of CenterPoint Energy's common stock per $1,000
principal amount of the notes, so long as specified conditions are met and
subject to adjustments under certain circumstances. The notes may be converted
at any time before 5 p.m. EST on the Redemption Date. Notes that are not
converted prior to that time, or for which a notice of conversion is withdrawn,
will be redeemed. CenterPoint Energy will satisfy its conversion obligation by
paying an amount in cash equal to the lesser of the aggregate principal amount
of notes converted and CenterPoint Energy's conversion obligation, and by
delivering shares of CenterPoint Energy's common stock to the extent that the
conversion obligation exceeds the aggregate principal amount of notes being
converted. On the Redemption Date, the notes will be redeemed unless (i) holders
surrender their notes for purchase in accordance with the Company Notice
previously delivered to holders and such notes are not withdrawn or (ii) such
notes are converted prior to 5:00 EST on the Redemption Date and the conversion
request is not withdrawn.

     Holders of notes at 5 p.m. EST on January 1, 2007, the regular record date
for the January 15, 2007 interest payment on the notes, will receive interest in
the amount of $14.375 per $1,000 principal amount of notes payable on January
15, 2007. Notes surrendered for conversion by holders during the period from 5
p.m. EST on January 1, 2007 to 9 a.m. EST on January 15, 2007, must be
accompanied by a payment of $14.375 per $1,000 principal amount of notes
surrendered for conversion, which amount equals the regular interest payment
that the holder is to receive on such notes. Holders that submit notes for
conversion after 9 a.m. EST on January 15, 2007, need not submit any interest
payment in connection with the conversion.
