ITEM 5.  OTHER EVENTS.

SOUTH TEXAS PROJECT DIESEL GENERATOR FAILURE

         On December 11, 2003, Texas Genco Holdings, Inc. ("Texas Genco"), a
majority-owned subsidiary of CenterPoint Energy, Inc., announced that on
December 9, 2003, one of three standby diesel generators at Unit 2 of the South
Texas Project nuclear facility ("STP") experienced a failure during a routine
monthly surveillance test. Texas Genco owns a 30.8 percent interest in STP. STP
Nuclear Operating Company personnel have informed the Nuclear Regulatory
Commission and are completing the analysis to determine the cause of the failure
and are developing a repair plan. The unit continues to operate at full power
and has two operational standby diesel generators. At this time, we cannot
predict the cost of repairs or if this event would require an outage.
