-- Certain units at BP (BP.L) Whiting Refinery in Indiana, US, briefly lost electric power on Sunday night.
The oil and gas company said in an emailed statement on Thursday that power was quickly restored, with the issue attributed to electrical systems. It added that the power interruption was not due to the operator's actions.
The statement comes after media speculation regarding the event and its impact on gas prices. BP said it does not speculate on market pricing or set oil prices.
