On the evening of October 2, a massive fire broke out<\/a> at Chevron\u2019s El Segundo refinery<\/a> just southwest of Los Angeles. The blaze was visible across the South Bay and drew a large emergency response, but it was ultimately contained without injuries<\/a>. While the fire was limited to a single process unit, the facility\u2019s importance to California\u2019s fuel supply means the incident could ripple through regional gasoline markets almost immediately, exacerbating an already challenging situation<\/a>.<\/p>\n Built in 1911, the El Segundo refinery is Chevron\u2019s largest on the West Coast, with a processing capacity of about 290,000 barrels of crude oil per day. (Contrary to multiple news reports, the facility does not produce oil–it processes oil). The facility plays an outsized role in California\u2019s fuel economy, supplying roughly<\/a> 20% of Southern California\u2019s gasoline and more than 40% of its jet fuel. Any disruption there carries implications far beyond Los Angeles County. Even a short-term outage can tip the balance in a state where fuel supplies are tightly constrained<\/a>.<\/p>\n California\u2019s gasoline market is unique in several respects that magnify the impact of such accidents. The state is effectively an island when it comes to refined products, with only limited pipeline connections to the broader U.S. refining system. On top of that, California requires its own specialized blend of gasoline to meet stringent environmental standards. CARB-compliant fuel cannot be easily substituted with supply from other states, and imports from Asia or the Gulf Coast typically require weeks to arrive. This leaves the state unusually exposed when local refineries experience disruptions.<\/p>\n The timing of this fire could hardly be worse for consumers. Inventories of gasoline in California were already running about 10% below their five-year average<\/a> in late September, according to federal data. Seasonal maintenance at refineries is also underway, which typically reduces output heading into the fall. Add in steady demand from motorists and elevated jet fuel consumption at Los Angeles International Airport, and the system has very little cushion. Even if Chevron brings the damaged unit back online quickly, the short-term effect is likely to be tighter supply and higher prices.<\/p>\n
