ITEM 5.  OTHER EVENTS AND REGULATION FD DISCLOSURE

On May 13, 2004, the Public Utility Commission of Texas approved TXU Energy's
request to raise electric prices for North Texas residential and business
customers. Continuing high natural gas prices led to TXU Energy's request.

This change will be implemented immediately and will raise the average monthly
residential electric bill of a customer using 1,000 kilowatt hours by 3.4
percent or $3.39.
