 to undertake an investigation of exactly what has happened by CenterPoint, find out what the reason for failure was, what must be done to fix it. CenterPoint said in a Sunday news release it expected power to be restored to 90% of its customers by the end of today. The utility has defended its preparation for the storm and said that it brought in about 1,200 additional workers from outside Houston. It has said it would have been unsafe to pre-position those workers inside the predicted storm impact area before Beryl made landfall.
