What caused the reduction in output at Viva Energy's Geelong refinery, and which units were affected?

The reduction in output was caused by a major fire that started in the alkylation unit — part of the gasoline complex — on Wednesday. While key processing units remained unaffected, the residue catalytic cracking unit is currently offline as operations stabilize.

What are Viva Energy's near-term production levels for diesel, jet fuel, and gasoline, and how does the company plan to manage supply continuity?

In the near term, the refinery will produce diesel and jet fuel at about 80% of capacity and gasoline at around 60%. Viva Energy stated it holds sufficient inventories to offset the reduced output and does not expect disruptions to customers.
