California drivers may soon face higher prices at the pump following a fire at Chevron’s El Segundo refinery, one of the state’s largest fuel producers. The blaze, which broke out on October 2, 2025, in the refinery’s Isomax 7 unit, was brought under control after several hours—but experts warn that even a short disruption could ripple across California’s tightly balanced fuel market.
Located just south of Los Angeles, the El Segundo refinery processes around 285,000 barrels of crude oil per day, supplying nearly 20% of Southern California’s gasoline and 40% of its jet fuel. Any interruption to operations can have an immediate effect on regional supply and pricing.
Chevron confirmed that parts of the facility remain offline while safety inspections and repairs continue. The company said it has made “operational adjustments” to maintain production levels but did not provide a timeline for full restoration. In the meantime, temporary flaring and reduced refining activity are expected.
Industry analysts say this could lead to a 5 to 15-cent increase per gallon of gasoline across California in the short term. “The state operates with very little spare refining capacity,” said energy economist Mark Finley. “When one of the big refineries goes down, even briefly, there’s nowhere else to turn for extra supply.”
Because California enforces strict fuel blend requirements, importing additional gasoline from other regions isn’t a quick fix. Tanker deliveries can take weeks to arrive, and imported fuels often cost more due to transportation and compliance costs.
If damage assessments reveal a longer repair timeline, the price surge could be far more severe. In past refinery disruptions, gas prices in California have spiked by 30 to 90 cents per gallon within days. Experts caution that much depends on how fast Chevron can restore normal operations.
The timing couldn’t be worse for drivers. Gas prices in California were already among the highest in the nation—averaging around $5.35 per gallon—before the fire. With refinery output reduced and supply chains stretched thin, even small shifts in production can cause noticeable changes at the pump.
The psychological impact of the incident may also fuel temporary panic buying, as motorists rush to fill their tanks before prices rise. This behavior can worsen short-term shortages and push prices up even faster.
Environmental agencies continue to monitor air quality in the El Segundo and South Bay areas, where residents reported visible smoke and the smell of burning fuel. Chevron has pledged full cooperation with local authorities and assured the public that no major health hazards have been detected.
If operations resume quickly, the impact may be limited to a brief price bump. But if repairs take weeks or months, California could face another period of volatile fuel prices—reminding consumers just how fragile the state’s energy infrastructure remains.
