Refinery explosions are not just alarming local incidents — they can ripple through the entire Western region’s fuel economy, causing sharp increases in gasoline prices consumers feel at the pump. This article breaks down how refinery fires, especially recent ones in California, impact gasoline prices throughout the western United States.

The Critical Role of Refineries in Gasoline Supply
Oil refineries are complex industrial facilities that convert crude oil into gasoline, jet fuel, diesel, and other petroleum products. In California alone, some refineries supply as much as 20% of the state’s gasoline and nearly 40% of its jet fuel. Because the western United States, especially California, depends heavily on local refineries due to environmental regulations and limited pipeline imports, any disruption can have a significant effect on fuel availability.
The El Segundo Chevron refinery, for example, is one of the largest oil-producing sites on the West Coast. When it shuts down, even temporarily, the impact is felt not just in California but all along the coast, stretching into states like Oregon, Washington, Nevada, and even parts of Canada.
Recent Refinery Explosions and Their Immediate Impact
Over the past year, multiple refinery fires have disrupted production:
- The October explosion and fire at Chevron’s El Segundo refinery, responsible for about 20% of Southern California’s motor vehicle fuel, caused immediate concern about price spikes.
- A fire at Valero’s refinery in Benicia, Northern California, also reduced daily output by 145,000 barrels.
- PBF Energy’s Martinez refinery experienced damage earlier, limiting refining capacity for months.
Each of these events has temporarily reduced gasoline supply on the West Coast, triggering price increases at the pump as refineries work to repair and restart operations.
“This particular refinery, anytime it shuts down, it impacts prices all along the western coast of the United States, and even into places like Vancouver, British Columbia.”
How and Why Gas Prices Fluctuate After Explosions
The frequency and severity of refinery incidents directly affect gasoline prices with variations typically between 5 and 90 cents per gallon in the Western U.S. For example, after the El Segundo explosion:
- Initial estimates projected up to a 90-cent spike per gallon due to concerns over extended shutdowns.
- As damage assessments showed the fire was contained to a smaller area, projections adjusted to a more moderate increase between 5 to 15 cents.
- Longer shutdowns or greater damage will push prices higher, potentially surpassing $5 per gallon in California alone.
Price increases are driven by supply reduction and higher wholesale fuel costs as remaining refineries ramp up production or fuel imports increase. Consumers often see these market changes reflected directly at gas stations within days.
Wider Regional Effects Across the West Coast and Beyond
Disruptions at large refineries uniquely affect the western U.S. because gasoline supplies there rely on fewer local facilities than in other parts of the country. The ripple effect can be summarized as:
- Higher prices in California spill over to Oregon, Washington, Nevada, and even as far north as British Columbia. For instance, gas prices in Nevada and California showed some of the largest weekly jumps nationally following recent fires.
- States like Oregon have experienced increases of several cents per gallon directly attributed to refinery supply constraints.
- Even with national crude prices fluctuating due to geopolitical events, refinery-specific issues often drive short-term price surges on the West Coast.
What This Means for the Future Gasoline Market
Beyond immediate price jumps, refinery explosions highlight ongoing challenges facing West Coast fuel markets:
- Many California refineries face permanent closures or capacity reductions, elevating the risk of persistent price volatility.
- Environmental regulations, costs of maintaining aging infrastructure, and damage risks from accidents like fires will shape the long-term supply landscape.
- Experts warn that without new capacity or alternative fuel sources, California gasoline could reach record average prices as high as $8 per gallon in the coming years.
Consumers and businesses heavily reliant on fuel should monitor refinery status updates closely, as even brief outages can translate to noticeable economic impacts.
