         This Post-Effective Amendment to the Registration Statement on Form S-8
is being filed pursuant to Rule 414 under the Securities Act of 1933, as amended
(the "Securities Act"), by the Registrant, the successor to Reliant Energy,
Incorporated (formerly Houston Industries Incorporated), a Texas corporation,
following a merger to effect a holding company reorganization effective as of
August 31, 2002. The Registrant hereby expressly adopts the Registration
Statement of Reliant Energy on Form S-8 (Registration No. 333-32413) as its own
registration statement for all purposes of the Securities Act and the Securities
Exchange Act of 1934, as amended, and hereby sets forth any additional
information necessary to reflect any material changes made in connection with or
resulting from the succession, or necessary to keep this Registration Statement
from being misleading in any material respect.

================================================================================

                             INTRODUCTORY STATEMENT

         Effective August 31, 2002, pursuant to the Agreement and Plan of Merger
(the "Merger Agreement") among Reliant Energy, Incorporated ("Reliant Energy"),
Reliant Energy MergerCo, Inc. ("MergerCo") and CenterPoint Energy, Inc.
("CenterPoint Energy" or "Registrant"), MergerCo merged into Reliant Energy, as
a result of which the outstanding shares of common stock, without par value, of
Reliant Energy were exchanged automatically on a share-for-share basis for
shares of common stock, par value $0.01 per share, of CenterPoint Energy, and
Reliant Energy became a subsidiary of CenterPoint Energy.

         Pursuant to the Merger Agreement, the unexpired employee stock options
assumed by Reliant Energy pursuant to the Agreement and Plan of Merger dated as
of August 11, 1996, as amended, by and among Houston Industries Incorporated,
Houston Lighting & Power Company, HIMerger, Inc., and NorAm Energy Corp. (the
"NorAm Merger Agreement") were assumed by CenterPoint Energy. Accordingly, all
stock issued pursuant to unexpired employee stock options assumed by Reliant
Energy pursuant to the NorAm Merger Agreement will be shares of the common stock
of CenterPoint Energy rather than shares of the common stock of Reliant Energy.

         The applicable registration fees were paid at the time of the original
filing of this Registration Statement.

amended (the "Securities Act"). In accordance with Rule 428 and the requirements

and Exchange Commission (the "Commission") either as part of this Post-Effective
Amendment to Registration Statement or as prospectuses or prospectus supplements
pursuant to Rule 424 under the Securities Act. The Registrant shall maintain a

                                      II-1

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Article 2.02.A.(16) and Article 2.02-1 of the Texas Business
Corporation Act and Article V of the Registrant's Amended and Restated Bylaws
provide the Registrant with broad powers and authority to indemnify its
directors and officers and to purchase and maintain insurance for such purposes.
Pursuant to such statutory and Bylaw provisions, the Registrant has purchased
insurance against certain costs of indemnification that may be incurred by it
and by its officers and directors.

         Additionally, Article IX of the Registrant's Amended and Restated
Articles of Incorporation provides that a director of the Registrant is not
liable to the Registrant for monetary damages for any act or omission in the
director's capacity as director, except that Article IX does not eliminate or
limit the liability of a director for (i) any breach of such director's duty of
loyalty to the Registrant or its shareholders, (ii) any act or omission not in
good faith that constitutes a breach of duty of such director to the Registrant
or an act or omission that involves intentional misconduct or a knowing
violation of law, (iii) a transaction from which such director received an
improper benefit, whether or not the benefit resulted from an action taken
within the scope of the director's office or (iv) an act or omission for which
the liability of a director is expressly provided for by statute.

         Article IX also provides that any subsequent amendments to Texas
statutes that further limit the liability of directors will inure to the benefit
of the directors, without any further action by shareholders. Any repeal or
modification of Article IX shall not adversely affect any right of protection of
a director of the Registrant existing at the time of the repeal or modification.

         See "Item 9. Undertakings" for a description of the Commission's
position regarding such indemnification provisions.

ITEM 9.  UNDERTAKINGS.

                  (a)  The undersigned registrant hereby undertakes:

                       (1)  To file, during any period in which offers or sales
         are being made, a post-effective amendment to this registration
         statement:

                            (i) To include any prospectus required by section
                  10(a)(3) of the Securities Act;

                            (ii) To reflect in the prospectus any facts or
                  events arising after the effective date of the registration
                  statement (or the most recent post-effective amendment
                  thereof) which, individually or in the aggregate, represent a
                  fundamental change in the information set forth in the
                  registration statement;

                            (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the registration statement or any material change to such
                  information in the registration statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii)
above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange
Act that are incorporated by reference in the registration statement.

                                      II-3

                       (2) That, for the purpose of determining any liability
         under the Securities Act, each such post-effective amendment shall be
         deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time shall
         be deemed to be the initial bona fide offering thereof.

                       (3) To remove from registration by means of a
         post-effective amendment any of the securities being registered which
         remain unsold at the termination of the offering.

                  (b) The undersigned registrant hereby undertakes that, for
         purposes of determining any liability under the Securities Act, each
         filing of the registrant's annual report pursuant to Section 13(a) or
         Section 15(d) of the Exchange Act (and, where applicable, each filing
         of an employee benefit plan's annual report pursuant to Section 15(d)
         of the Exchange Act) that is incorporated by reference in this
         registration statement shall be deemed to be a new registration
         statement relating to the securities offered therein, and the offering
         of such securities at that time shall be deemed to be the initial bona
         fide offering thereof.

                  (c) Insofar as indemnification for liabilities arising under
         the Securities Act may be permitted to directors, officers and
         controlling persons of the registrant pursuant to the provisions
         described under Item 6 above, or otherwise, the registrant has been
         advised that in the opinion of the Commission such indemnification is
         against public policy as expressed in the Securities Act and is,
         therefore, unenforceable. In the event that a claim for indemnification
         against such liabilities (other than the payment by the registrant of
         expenses incurred or paid by a director, officer or controlling person
         of the registrant in the successful defense of any action, suit or
         proceeding) is asserted by such director, officer or controlling person
         in connection with the securities being registered, the registrant
         will, unless in the opinion of its counsel the matter has been settled
         by controlling precedent, submit to a court of appropriate jurisdiction
         the question whether such indemnification by it is against public
         policy as expressed in the Securities Act and will be governed by the
         final adjudication of such issue.


                                      II-4

                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this
Post-Effective Amendment to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Houston, the State of Texas, on
