The Tesoro oil refinery in Kapolei is still not processing crude oil this morning, two days after a power outage.

Spokesman Lance Tanaka said the plant’s backup generator was offline during the power interruption, so employees had to do an emergency shutdown.

The refinery hopes to be producing again by tomorrow, after systems are brought back up one by one. But it will be processing below its capacity of 94,000 barrels a day.

The refinery is the top supplier of transportation fuels in Hawaii, including gasoline, jet fuel and ship fuel. It has direct pipelines to Honolulu International Airport and Joint Base Pearl Harbor-Hickam.

Tanaka says supply has not been interrupted.

The facility is one of only two oil refineries in Hawaii.
