                 TEXAS GENCO REPORTS THIRD QUARTER 2004 RESULTS
                LOSS REFLECTS IMPAIRMENT CHARGE FOR PENDING SALE

         HOUSTON - OCTOBER 28, 2004 - Texas Genco Holdings, Inc. (NYSE: TGN), an
81 percent-owned subsidiary of CenterPoint Energy, Inc. (NYSE: CNP), today
reported a net loss of $311 million, or $3.89 per share, for the third quarter
of 2004, which includes an after-tax impairment charge of $426 million ($649
million pretax) related to the pending sale of the company's coal, lignite and
gas-fired generation plants. As a result of the signing of the definitive
agreement described below, and in accordance with Statement of Financial
Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal
of Long-Lived Assets", the company ceased depreciation on its coal, lignite and
gas-fired generation plants at the time these assets were considered "held for
sale". This resulted in a decrease in depreciation expense of $24 million after
tax ($37 million pretax) for the quarter. In accordance with SFAS No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions", the
company also recorded a curtailment expense related to postretirement benefits
of $11 million after tax ($17 million pretax), which is included in operations
and maintenance expense. Excluding these sale-related impacts, net income for
the third quarter of 2004 was $102 million, or $1.27 per share, compared to $82
million, or $1.03 per share, for the same period of 2003.

         For the nine months ended September 30, 2004, the company reported a
net loss of $170 million, or $2.13 per share, including the sale-related impacts
described above. Net income for the nine months ended September 30, 2003, was
$204 million, or $2.55 per share, including a non-cash gain of $99 million
($1.24 per share) from the adoption of Statement of Financial Accounting
Standards No. 143, "Accounting for Asset Retirement Obligations". Excluding the
sale-related impacts, net income for the nine months ended September 30, 2004
was $243 million, or $3.03 per share, and income before the cumulative effect of
an accounting change for the same period of 2003 was $105 million, or $1.31 per
share.

          Excluding the pre-tax impacts related to the sale noted above,
operating income for the third quarter of 2004 improved by $28 million from the
prior year primarily due to higher wholesale electricity prices for baseload
products and improved availability of baseload units.

         On July 21, 2004, CenterPoint Energy and Texas Genco announced a
definitive agreement for GC Power Acquisition LLC, a newly formed entity owned
in equal parts by affiliates of The Blackstone Group, Hellman & Friedman LLC,

Kohlberg Kravis Roberts & Co. L.P. and Texas Pacific Group, to acquire Texas
Genco for approximately $3.65 billion in cash. The transaction, subject to
certain regulatory approvals, will be accomplished in two steps. The first step,
expected to be completed in the fourth quarter of 2004, involves Texas Genco's
purchase of the 19 percent of its shares owned by the public for $47 per share,
followed by GC Power Acquisition's purchase of a Texas Genco subsidiary that
will then own Texas Genco's coal, lignite and gas-fired generation plants. In
the second step of the transaction, expected to take place in the first quarter
of 2005 following Nuclear Regulatory Commission approval, GC Power Acquisition
will complete the acquisition of Texas Genco, the principal remaining asset of
which will then be Texas Genco's interest in the South Texas Project nuclear
facility.
