EXHIBIT 99(a) NEWS [TXU LOGO] RELEASE - -------------------------------------------------------------------------------- 1601 Bryan Street Dallas, Texas 75201-3411 FOR IMMEDIATE RELEASE --------------------- HIGH GAS PRICES LEAD TO TXU ENERGY REQUEST TXU's Price to Beat Remains Lowest in Texas DALLAS - JULY 23, 2003 - TXU Energy today filed a request with the Public Utility Commission of Texas to raise the company's electricity prices for North Texas customers, in order to reflect the higher market price of natural gas. The change would raise an average monthly residential electric bill of a customer using 1,000 kilowatt hours by 3.7 percent or $3.61 per month. The Commission has 45 days, or as soon as practical thereafter, to review the company's request. "While we understand that any increase is difficult for our customers, we work hard to keep our prices competitive," said Carl Bracy, TXU Energy senior vice president. "When this change goes into effect, our Price to Beat will still remain the lowest in the state." The Texas Electric Choice Act allows for changes in electricity prices when natural gas or purchased power prices increase or decrease beyond the threshold. This flexibility contributes to making Texas the most competitive electricity market in the United States. Natural gas is a key component in generating electricity and as gas prices rise, the price of electricity also increases. TXU Energy's request to the PUC reflects the higher market prices.
