A total power failure from utility provider ComEd stopped production at a key Midwest refining site operated by ExxonMobil. The outage at the 275,000 bpd Joliet plant halted the delivery of 11 million gallons of gasoline and diesel per day, which the company clarified was not a scheduled shutdown. The firm is losing tens of millions of dollars every day output remains impacted, per a statement.

U.S. national average diesel prices reached a record $6.45 per gallon as the region entered peak demand season. Market strain is compounded by a partial outage at BP's Whiting refinery in Indiana, global refining shortages, and a Russian ban on diesel exports.
