However, the company is still working to restore power at its Port Arthur, Texas, refinery.
Refinery employees are continuing to work to ensure the units have supplies of fresh water and industrial gases to begin manufacturing products again.
As such, all three refineries remain shut down.
Valero spokesman Bill Day says the company does not yet have a timetable as to when the three Gulf Coast refineries will be back online. The company shut down the refineries in response to Hurricane Ike.
Valero¬ís other Gulf Coast refineries, which include facilities in Corpus Christi and St. Charles, La., are operating at normal rates.
To date, the company has also reopened 64 company-owned retail stores in the Houston region and is continuing to open more as quickly as it can.
San Antonio-based Valero is an oil refining and marketing company that owns and operates 16 refineries in the United States, Canada and the Caribbean.
