A major fire broke out at Chevron’s El Segundo refinery the night of October 2nd, disrupting operations during a pivotal moment for West Coast fuel supply. The incident, which occurred at the refinery’s Isomax hydrocracker unit, has drawn significant attention due to Chevron’s critical role in supplying gasoline and jet fuel to Southern California and beyond.
Immediate Impacts on Fuel Supply
Chevron’s El Segundo refinery processes roughly 290,000 barrels of oil per day, accounting for about 20% of Southern California’s gasoline and 40% of its jet fuel supply. The fire was reported in the Isomax unit, a hydrocracking process. EIA lists the refinery as having 55,000 barrels per day of hydrocracking capacity. The fire primarily affected jet fuel production, with experts estimating that maximum jet mode yields may be 50% or more from the Isomax unit. As a result, short-term losses are expected in both jet fuel and gasoline volumes. Chevron and other suppliers are actively scrambling to secure replacement volumes, and market participants reported Chevron buying from North/South CARBOB spot markets immediately following the fire.
Market Dynamics and Resilience
Stillwater expects spot fuel prices, particularly jet fuel, to spike in the short term, with longer-term price movement hinging on the damage assessment and repair timeline. Some estimates suggest gasoline pump prices could rise by 5 to 15 cents per gallon but little retail price movement happened over the weekend.1 While the gasoline market is currently buffered by ample inventory and high RVP supply just weeks away, Southern California remains vulnerable as the nearby Phillips 66 Wilmington refinery permanent shut down in process, removing crucial production buffers from the system.
Supply Chain Adjustments
With El Segundo curtailed, Northern California refineries are expected to pick up the slack to help supply Southern California, but this could tighten supplies in the Bay Area as product is rerouted. Substantial volumes of gasoline are on the water headed to California, according to Vortexa. Longer term, logistical constraints and California’s stringent fuel standards limit rapid replacement from external sources.
Uncertainties and Lessons Learned
Chevron has not provided a specific timeline to resume normal operations, and the true impact on supply will depend on the extent of equipment damage and duration of repairs. Although the dramatic nature of the fire suggests severe consequences, initial reports indicate the damage may be limited and not to the main refinery infrastructure, potentially enabling quicker inspection and repair. But Stillwater’s industry veterans note that, in today’s operational and regulatory environment, any outage due to such events create more severe impacts – a reflection of California’s increasingly constrained refining landscape.
The Value of Forward-Looking Market Intelligence
Events like the Chevron El Segundo fire underscore how essential it is for industry stakeholders to have access to up-to-date, expert analysis of the evolving West Coast fuel market. Stillwater Associates’ comprehensive West Coast Supply/Demand Outlook through 2040 provides crucial guidance for navigating supply disruptions, refinery closures, and market transitions while incorporating regional flows, imports, and policy dynamics. As California faces mounting pressures from declining refinery capacity and shifting fuel regulations, Stillwater’s long-term outlook equips fuel suppliers, policymakers, and regulators with the insights needed to anticipate challenges, adapt strategies, and maintain energy resilience during periods of rapid market change.

Bottom Line: The El Segundo fire poses a risk of tighter jet fuel and gasoline supply for Southern California, likely creating volatility in prices until the situation stabilizes. Market resilience will depend on prompt repairs, alternative supply logistics, and ongoing adaptation by West Coast refineries as California continues to grapple with shrinking conventional refining capacity. In this environment, Stillwater Associates’ expert Supply/Demand Outlook through 2040 is an essential resource: it equips stakeholders with actionable forecasts and scenario analyses to navigate uncertainty, assess risk, and plan strategically for future disruptions and policy shifts in the region’s complex fuel market.
