KEY POINTS
  • Philadelphia Mayor Jim Kenney announces that Philadelphia Energy Solutions is shuttering operations at the East Coast's largest refinery after suffering severe damage from an explosion and fire last week.
  • The shutdown could result in a short-term spike in mid-Atlantic region gasoline prices, with one expert seeing a potential for a 20 cents per gallon move.
  • The national average is unlikely to surpass last year's level of $2.84.
Customers pump gasoline at a gas station in the Bronx, where gas prices are over $3.00 per gallon, June 1, 2018 in New York.

The permanent shutdown of the fire-damaged Philadelphia Energy Solutions refining complex could send gasoline prices higher across the U.S., but particularly in the mid-Atlantic region, where they could spike temporarily just around the time drivers fill up for Fourth of July holiday.

The refinery was the largest and oldest on the East Coast and accounts for about 27% of that region's refining capacity. The 330,000 barrel a day refinery was closed following explosions and a massive fire last week.
