UPDATE 1-Valero: most of Texas City refinery has power

(Adds details, spokesman's quotes, background)

NEW YORK, Sept 16 (Reuters) - Valero Energy Corp (VLO.N) said on Tuesday that power has been restored to most production units at its 245,000-barrel-per-day Texas City, Texas, oil refinery in the wake of Hurricane Ike.

Company spokesman Bill Day said in an email the company is working to restore power at its 295,000-bpd Port Arthur, Texas, refinery. Power has been restored to most production units at the 130,000-bpd Houston, Texas, refinery.

"All three refineries remain shut down," Day said.

Crews are working through other issues, such as ensuring supplies of fresh water and industrial gases, he added.

Hurricane Ike slammed into the Texas gulf coast on Saturday as a powerful Category 2 storm.

"At this time we do not have a timetable either for when startup would begin at any of the refineries or how long the startups would take," Day noted.

Valero's other Gulf Coast refineries remain in operation at planned rates, the spokesman added. (Reporting by Haitham Haddadin; editing by Jim Marshall)
