EXHIBIT 99.1 FOR FURTHER INFORMATION: Sandy Fruhman, Media (713) 207-3123 Marianne Paulsen, Investors (713) 207-6500 Dennis Barber, Investors (713) 207-3042 FOR IMMEDIATE RELEASE: April 29, 2002 RELIANT ENERGY REPORTS FIRST QUARTER 2002 EARNINGS HOUSTON, TX. - Reliant Energy, Incorporated (NYSE: REI) today reported net income for the first quarter of 2002, of $225 million, or $0.76 per diluted share, compared to net income of $262 million, or $0.90 per diluted share, for the first quarter of 2001. Reliant Energy's earnings reflect its approximately 83 percent interest in Reliant Resources (NYSE: RRI). In the 2001 period, there were two unusual items which included a $62 million after-tax, non-cash gain from the implementation of Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities", and a $65 million after-tax, non-cash charge related to the redesign of benefit plans for employees of Reliant Resources. The decrease in net income for the first quarter of 2002, was largely driven by a decline in earnings from the company's wholesale energy segment due to less favorable market conditions somewhat offset by earnings in the retail energy segment. In addition, milder weather in the 2002 period negatively impacted earnings from the natural gas distribution segment. Results for the first quarter of 2002 also reflected the benefit of reduced interest expense partially offset by a negative impact related to the ZENS securities. On January 1, 2002, the company discontinued amortizing goodwill in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets". During the first quarter of 2001, $21 million of goodwill amortization expense was recognized. "This has been a very productive first quarter with the successful implementation of retail electric competition in the Texas market," said Steve Letbetter, chairman, president and chief executive officer. "Our business units handled this transition very well and effectively implemented their strategies for the restructured environment. Our performance, while negatively affected by weather, a weaker economy and unfavorable market conditions, remained solid." EARNINGS BEFORE INTEREST AND TAXES BY SEGMENT DETAILED ELECTRIC OPERATIONS During 2001, the company's electric operations segment reflected the regulated electric utility business, including generation, transmission and distribution, and retail electric sales. As of January 1, 2002, with the opening of the Texas market to full retail electric competition, generation and retail sales were deregulated. Retail electric sales involve the sale of electricity and related services to end users of electricity and were included as part of the bundled regulated

service prior to 2002. Retail electric sales are now reported as the retail energy segment of Reliant Resources. Beginning in 2002, Reliant Energy will report two new segments for what was the former electric operations segment: . Electric Generation, and . Electric Transmission and Distribution The previously regulated generation operations in Texas are being reported in the new electric generation segment. The electric transmission and distribution segment will report results from two sources. This segment includes the regulated electric transmission and distribution operations, which recovers the cost of its service through an energy delivery charge, as well as impacts of generation-related stranded costs recoverable by the regulated utility. As a result of the implementation of deregulation and the corresponding new segments, there are no meaningful comparisons for these segments against prior periods. Although the company's retail sales are now conducted by Reliant Resources, retail customers remained regulated customers of Reliant Energy HL&P through the date of their first meter reading in 2002. Sales during this transition period produced EBIT (earnings before interest and taxes) of $14 million in the first quarter of 2002, reflected in the electric operations segment. The company expects to incur transition expenses during the remainder of the year and a substantial portion of these earnings is expected to be offset. ELECTRIC GENERATION The new electric generation segment is comprised of over 14,000 MW of electric generation located entirely in the state of Texas, and will be called Texas Genco after the company's restructuring. This segment reported a $52 million loss before interest and taxes for the first quarter of 2002. ELECTRIC TRANSMISSION & DISTRIBUTION The new electric transmission & distribution segment reported EBIT of $245 million for the first quarter of 2002. This reflected EBIT of $104 million for the regulated electric transmission and distribution business, and EBIT of $141 million associated with certain generation-related regulatory assets (ECOM, or Exess Cost Over Market, true-up) recorded pursuant to the Texas restructuring law as explained below. Under the deregulation law, each power generator that is unbundled from an integrated electric utility in Texas has an obligation to conduct state-mandated capacity auctions of 15 percent of its capacity. In addition, under a master separation agreement between Reliant Energy

and Reliant Resources, Texas Genco is contractually obligated to auction all capacity in excess of the state-mandated capacity auctions. The auctions conducted periodically between September 2001 and March 2002 were consummated at prices below those assumed by the Texas Public Utility Commission's ECOM model. Under the Texas restructuring law, a regulated utility may recover any difference between market prices received through the auction process and the Texas Public Utility Commission's earlier estimates of those market prices. This difference, recorded as a regulatory asset, produced the $141 million of EBIT in the first quarter of 2002. In the transmission and distribution business, throughput declined 5 percent compared to the first quarter of 2001 due to reduced energy delivery in the industrial sector. Customer growth was strong with an addition of 7,000 metered customers since December 2001, or approximately 2 percent growth on an annualized basis. NATURAL GAS DISTRIBUTION The natural gas distribution segment reported EBIT of $110 million for the first quarter of 2002 compared to EBIT of $137 million for the same period of 2001. The amount of goodwill amortization expense recognized in the first quarter of 2001 was $8 million. Usage in the natural gas distribution segment declined 10 percent in the first quarter of 2002 compared to the same period in 2001. This decline was due to milder weather compared to the 2001 period as well as to reduced consumption. PIPELINES AND GATHERING EBIT for the pipelines and gathering segment declined slightly to $38 million for the first quarter of 2002 compared to $39 million for the same period of 2001. The amount of goodwill amortization expense recognized in the first quarter of 2001 was $4 million. WHOLESALE ENERGY Earnings before interest and taxes for the wholesale energy segment were $114 million in the first quarter of 2002, compared to $229 million in the same period of 2001. The decrease was primarily due to less favorable market conditions, which resulted in lower operating margins from trading and marketing, power generation, and ancillary services, partially offset by the contribution from the Orion Power Holdings acquisition, which closed in February. The segment also had increased operations and maintenance expenses and higher depreciation expense, primarily due to the Orion Power acquisition, as well as lower equity income from an investment in the El Dorado Energy plant in Nevada. The quarterly earnings comparison reflects a $38 million reserve relating to our California receivables taken in the first quarter of 2001, as well as a release and adjustment of California receivables reserves totaling $33 million in the first quarter of 2002. The segment also had lower emissions expense in the first quarter of 2002. The Orion Power operations contributed $33 million of EBIT for the quarter. EUROPEAN ENERGY The European energy segment produced EBIT of $18 million in the first quarter of 2002, compared to $21 million in the 2001 comparable period. The decrease was primarily a result of reduced power generation margins, lower ancillary services and district heating revenues and increased plant outages in the first quarter of 2002. Partially offsetting these factors were a $19 million net gain recognized in fuel expense related to the change in valuation of our stranded cost contracts, improved trading margins and lower amortization expense. RETAIL ENERGY The company's retail energy segment produced EBIT of $48 million in the first quarter of 2002, compared to a loss of $3 million in the first quarter of 2001. The Texas retail electricity market opened to full competition in January 2002. At that time, the retail energy segment began serving approximately 1.7 million electricity customers in the greater Houston, Texas area. OTHER OPERATIONS The company's other operations, which include its thermal systems, power systems, new ventures businesses, various real estate used in business operations, remaining operations in Latin America and unallocated corporate costs, reported a loss before interest and taxes for the first quarter of 2002 of $13 million. This compares to a loss before interest and taxes of $131 million for the same period of 2001. The 2001 results include a $101 million non-cash charge

related to the redesign of benefit plans for employees of the company's unregulated businesses in anticipation of the spin-off of Reliant Resources. OUTLOOK FOR 2002 After the spin-off of Reliant Resources, CenterPoint Energy will include primarily the regulated businesses of electric transmission and distribution, natural gas distribution and pipelines and gathering. CenterPoint Energy will also include the Texas power generation assets until at least 2004 when Reliant Resources has an option to purchase these assets. Reliant Resources provides competitive energy services activities including nonregulated power generation, wholesale energy trading and marketing, retail energy services and wholesale energy in Europe. Assuming completion of the spin-off of Reliant Resources, 2002 earnings per share for the segments that will comprise CenterPoint Energy are expected to be in the range of $1.17 to $1.22, excluding its prior interests in Reliant Resources. Reliant Resources, Inc. (NYSE: RRI), which completed its initial public offering of approximately 20 percent of its shares in May 2001, expects to achieve earnings of $1.80 to $2.00 per share.
