News Summary

California’s oil refining sector is poised for significant change as Phillips 66’s Wilmington facility and Valero’s Benicia refinery prepare to close by 2026. The closures combined will eliminate 284,000 barrels-per-day of capacity, impacting around 1,300 jobs. Local legislators express concerns about economic repercussions, including rising gas prices and increased reliance on imports. The shutdowns highlight ongoing regulatory challenges within California’s energy landscape, potentially driving gas prices beyond $8 per gallon by late 2026.

California is set to experience significant changes in its oil refining landscape as two major refineries—Phillips 66’s Wilmington facility and Valero’s Benicia refinery—are scheduled to shut down by 2026. The Phillips 66 facility is expected to close by October 2025, while the Valero refinery will cease operations in the following year. These closures combined will eliminate approximately 284,000 barrels-per-day of refining capacity, accounting for nearly 20% of California’s total capacity.

The decision to close these refineries has raised concerns among local legislators, particularly with Assemblymember Mike A. Gipson emphasizing the potential job losses and their broader economic impacts. Many of the affected workers reside in Gipson’s district, which may face increased economic challenges due to impending layoffs. The Phillips 66 facility supports around 900 workers, while Valero employs approximately 400.

Both refinery closures are influenced by the increasing regulatory pressures and compliance costs. The Valero refinery, in particular, has faced several significant fines for air quality violations, including an $82 million penalty in 2024. Phillips 66 has cited strict environmental regulations as a significant factor leading to its decision to close. These regulations have fueled concerns over the future of California’s energy landscape, typically characterized by high gas prices averaging around $4.85 per gallon, significantly higher than the national average of $3.16.

As California currently processes about 24% of its crude oil requirements, the closures of these refineries may compel the state to rely more on imported fuel. This shift is likely to increase shipping costs and emissions associated with tanker vessels, further complicating California’s existing environmental challenges. Fuel prices are expected to see volatility, with estimates predicting potential increases ranging from less than $1 to exceeding $8 per gallon by late 2026 following the closures.

Experts warn that the closures will exacerbate economic and environmental challenges, including the reliance on non-local energy supplies that may not adhere to California’s stringent environmental standards. The California Air Resources Board has been criticized for failing to assess the impact of its regulations on consumers and drivers, which has fueled ongoing debates among legislators about the management of the oil and gas sector in the state.

Aside from the concerns regarding fuel supply and prices, there have also been discussions around the potential future use of the closed refinery sites. While there are suggestions for alternative industrial developments, these proposals may face community opposition due to health and environmental concerns.

As California braces for these shutdowns, the combination of job losses, economic uncertainty, higher gas prices, and increased dependence on imported fuels paints a complex picture for the state’s energy future.
