"Our first quarter earnings were significantly better than the first quarter of last year," said David Tees, president and chief executive officer of Texas Genco. "We continue to benefit from higher wholesale electricity prices which are driven by high natural gas prices. In addition, our solid fuel baseload generating units operated well, which when combined with the higher electricity prices, produced a significant improvement in our financial performance for the quarter."

Texas Genco reported increased revenues compared to the same period of 2003, continuing to benefit from increased prices for baseload products. Operation and maintenance expenses for the first quarter of 2004 were lower than the prior year. The first quarter of 2004 had lower expenses associated with planned and unplanned outages compared to the same quarter of 2003.

2004 OUTLOOK

The company reiterated its full year 2004 earnings estimate of $3.35 - $3.75 per share. This estimate reflects over $1 billion of capacity revenues under contract for 2004, including approximately 94 percent of its available baseload capacity. Earnings for 2004 will be highly dependent on the operating performance of the company's baseload generating units.
