HOUSTON - March 31, 2004 - CenterPoint Energy, Inc.'s (NYSE:CNP) electric transmission and distribution subsidiary, CenterPoint Energy Houston Electric, today filed with the Public Utility Commission of Texas (PUC) the final true-up application required by the 1999 Texas Electric Choice Law.

CenterPoint Energy, as well as other major parties, including consumer groups, unions, businesses and environmental groups were active supporters of the Texas Electric Choice Law. The 1999 legislation gave customers the ability to choose their retail electric providers beginning in 2002. It also required electric utilities to subject their retail and generation activities to competition and limited their regulated operations to transmission and distribution. The law also authorized electric utilities to recover in 2004 a "true-up" balance composed of stranded power plant costs, the cost of environmental controls and certain other transition costs, primarily through the issuance of low interest bonds. Repayment of the bonds will be through charges paid by retail electric providers for electric delivery services.

CenterPoint Energy's true-up balance is $3.8 billion. An additional $631 million in interest could be added if approved in a pending court proceeding.

"Each year our company makes hundreds of millions of dollars in investments in transmission and distribution infrastructure to serve our communities," said David M. McClanahan, president and chief executive officer for CenterPoint Energy. "To do so, we must have access to capital markets on reasonable terms. The outcome of this proceeding will have a significant effect on the cost and availability of capital to our company."

The impact on residential customers should be modest. Once the PUC completes its review, the company plans to issue securitization bonds that attract lower interest rates. Based on today's interest rates, the bonds that would be required to securitize the final true-up balance set forth in the application would require payments of approximately $330 million annually. These bond payments would result in an increase in the rate CenterPoint Energy charges retail electric providers by about one-half cent per kilowatt hour (kwh). Even if the retail electric provider passes on the full amount to residential customers, the effect would be an increase of approximately $5 per month (using the PUC's benchmark of 1,000 kwh per residential customer).

In addition, CenterPoint Energy currently gives each retail provider a credit (technically known as an "excess mitigation credit"). This credit, which is not based on the final true-up balance, will likely be discontinued. Customers may ultimately find their monthly bills impacted by their retail providers' treatment of several factors, including the final true-up balance, the termination of the excess mitigation credits and fuel cost adjustments. Depending on the specific retail electric provider involved, the combined impact of these factors on retail customers could range from a slight decrease to an increase of about one cent per kwh.

A final decision is expected by the PUC in late August. The docket number is 29526 and can be accessed on the PUC's web site at www.puc.state.tx.us./index.cfm.
