Company president and chief executive Joe Domino told The Beaumont Enterprise that the company had reconnected about 18,000 customers by Tuesday afternoon. But about 370,000 remain without service.
Entergy serves 26 counties in southeast Texas, including Ike hard-hit Galveston County and the Bolivar Peninsula.
Domino estimates power will return to customers: in the Silsbee-Lumberton-Kountze areas by Sept. 29; to the Orange-Vidor areas by Sept. 21; to the Winnie-Anahuac areas by Sept. 25; and to the Dayton-Liberty, Ames and Batson areas by Sept. 25.
Some customers in those areas can't receive power now because of Ike damage.
Domino say the company has about 7,000 people working now to restore power and another 7,000 are on the way.
