                    TEXAS GENCO'S BOARD AUTHORIZES INCREASED
                         OWNERSHIP IN STP NUCLEAR PLANT

      HOUSTON, TX - May 28, 2004 - The Board of Directors of Texas Genco
Holdings, Inc. (NYSE:TGN), a majority-owned subsidiary of CenterPoint Energy,
Inc. (NYSE: CNP), voted to exercise its right of first refusal to purchase up to
the entire 25.2 percent interest in the South Texas Project Electric Generating
Station (STP) that is currently owned by American Electric Power (AEP).

      In addition to AEP, the 2,500 megawatt nuclear plant is owned by Texas
Genco (30.8 percent), City Public Service of San Antonio (CPS) (28 percent) and
Austin Energy (16 percent).

      AEP had previously announced that it had received an offer of $333
million, subject to certain adjustments, to purchase its 630 megawatt interest.
Under the STP Participation Agreement, co-owners wishing to acquire AEP's
interest are entitled to do so at the proposed sale price.

      Austin Energy indicated that it will not exercise its right of first
refusal, while CPS indicated that it intends to purchase at least 12 percent or
300 megawatts. Accordingly, Texas Genco should be entitled to purchase a 13.2
percent interest or 330 megawatts from AEP.

      Texas Genco Holdings, Inc., based in Houston, Texas, is one of the largest
wholesale electric power generating companies in the United States with over
14,000 megawatts of generation capacity, of which approximately 2,500 megawatts
are currently in mothball status. It sells electric generation capacity, energy
and ancillary services in one of the nation's largest power markets, the
Electric Reliability Council of Texas (ERCOT). Texas Genco has one of the most
diversified generation portfolios in Texas, using natural gas, oil, coal,
lignite, and uranium fuels. The company owns and operates 60 generating units at
11 electric power-generating facilities and owns a 30.8 percent interest in a
nuclear generating plant. Texas Genco currently is a majority-owned subsidiary
of CenterPoint Energy, Inc. For more information, visit our web site at
