Exxon Mobil shut its 264,000-barrel-per-day refinery in Joliet, Illinois, following a power outage that occurred on Sunday afternoon. Power was restored later that evening, but the outage triggered the refinery's safety flare and led to a plant-wide shutdown. The company is currently assessing the refinery's status, and the cause of the incident is under investigation. Units are being stabilized, and the refinery is expected to return to normal service by the end of this week, according to IIR Energy. The Joliet refinery supplies key fuels to consumers in the U.S. Midwest, producing approximately 11 million gallons of gasoline and diesel fuel daily. This disruption comes at a time of already tight global fuel supplies, exacerbated by the conflict in the Middle East and attacks on Russian refineries, alongside strong export demand tightening domestic inventories. The U.S. national average price for diesel surpassed $6 a gallon last week for the first time.
