California is now importing gasoline through roundabout shipping routes, including tankers routed via the Bahamas, as the state’s refining capacity shrinks under a wave of permanent plant closures. The Valero Benicia refinery, one of Northern California’s last major fuel producers, will keep making gasoline only through April 2026 before shifting entirely to imports. With Phillips 66 also shutting down its Los Angeles-area refinery, the state faces a supply gap that is already pushing costs higher and raising hard questions about whether regulators planned adequately for the transition.
Benicia Refinery Winds Down by Spring
Governor Gavin Newsom confirmed in a January 2026 statement that Valero’s Benicia facility will keep producing fuel through April 2026, after which the refinery will be fully idled. Under Valero’s updated plan, the Benicia site will then supply Northern California through a combination of existing inventories and imported gasoline and diesel. That timeline gives the region only a short remaining window of in-state production before a key source of locally refined fuel goes dark and the Bay Area becomes far more dependent on marine deliveries.
Newsom’s statement explicitly referenced the state’s refinery transparency and resupply policy framework, built on legislation known as SB X1-2, which was designed to prevent price spikes during refinery outages. But that framework was crafted around temporary maintenance shutdowns and unplanned disruptions, not the permanent retirement of a major plant. Once Benicia stops processing crude, Northern California will depend on fuel shipped in from other states or overseas, a structural shift that no inventory mandate was originally designed to manage over the long term, especially if several facilities exit the market in close succession.
Phillips 66 Closures Shrink State Capacity
The Benicia wind-down does not exist in isolation. Phillips 66 has announced it will close its Los Angeles-area refinery, a move that state energy officials have cited as removing a substantial share of California’s total refining capacity. That decision comes on the heels of the Phillips 66 Santa Maria facility, which ended operations in early 2023 and is now headed for demolition under a formal environmental review process in San Luis Obispo County. The decommissioning work underscores that these closures are not mothballings, but permanent exits from the state’s fuel production system.
Industry executives and analysts point to a combination of stringent emissions rules, carbon reduction mandates, and uncertainty about future compliance costs as key reasons for this retreat. California’s long-term policy trajectory is explicitly aimed at phasing down fossil fuels, which makes multimillion-dollar refinery upgrades harder to justify. Operators like Phillips 66 and Valero have responded by reallocating capital to other regions rather than extending the life of plants facing a shrinking operational horizon. The result is a rapid contraction in in-state refining that outpaces the build-out of replacement import infrastructure, leaving the system more exposed to global market swings.
Bahamas Shipping Route Fills the Gap
The supply consequences are already visible on the water. U.S. gasoline cargoes are now being routed through the Bahamas before heading to California, adding distance and cost to the state’s fuel supply chain. That circuitous path reflects both a tight tanker market and the geographic reality that California, isolated on the West Coast with limited pipeline connections to Gulf Coast refineries, must compete for seaborne cargoes when local production drops. Chartering vessels for these longer voyages is expensive, and those premiums ultimately show up in retail prices.
Federal data from the U.S. Energy Information Administration’s weekly petroleum status tables for the West Coast region provide one of the clearest public windows into how rapidly imports are replacing domestic refinery output. In that dataset, California sits within the PADD 5 market, where shifts in refinery utilization, stock levels, and product imports can be tracked week by week. At the same time, the California Energy Commission’s own accounting of foreign crude supplies feeding state refineries shows that California has long relied heavily on overseas oil; as refineries close, that dependence is shifting from imported crude to imported finished gasoline and diesel, layering new logistical risks onto an already complex system.
State Inventory Rules May Worsen Short-Term Costs
Regulators are trying to get ahead of these risks. The California Energy Commission convened a pre-rulemaking workshop on refinery resupply planning under AB X2-1, a law that gives the state authority to require refiners and importers to hold minimum inventories and submit detailed resupply plans. The intent is to reduce the frequency and severity of price spikes when individual plants go offline, by ensuring there is always a buffer of fuel in storage and a clear schedule for replenishing it. Workshop materials and staff presentations outline how these obligations would fall on the remaining operators as the refinery fleet shrinks.
However, the design of these rules introduces trade-offs. A proposed framework released to stakeholders, summarized in a commission staff concept document on inventories and resupply, would effectively require companies to buy and store more gasoline and diesel than immediate demand justifies. During a period when multiple refineries are shutting down and imports must cover a growing share of consumption, those mandates could force traders to compete more aggressively for cargoes in a global market where tanker space is already scarce. The state’s broader policy framework for energy and climate treats these inventory cushions as a consumer protection tool, but without ample local refining to refill tanks cheaply, the buffers can become another cost multiplier that front-loads high-priced imports into the system.
$8.43 Per Gallon: A Warning From Sacramento
The price trajectory has drawn sharp warnings from Republican lawmakers. Senate Minority Leader Brian W. Jones of San Diego argued in May 2025 that average pump prices could jump by three-quarters to roughly $8.43 per gallon as refineries close and supply chains lengthen. His projection, issued through his official Senate office, frames the refinery exodus as a predictable outcome of state policy choices rather than an unavoidable response to global energy trends, and it has become a touchstone in the political fight over California’s climate agenda.
Whether that specific $8.43 figure materializes will depend on a volatile mix of crude benchmarks, shipping rates, and how quickly alternative supply sources can be secured. But the direction of the pressure is not in dispute: less local refining capacity means more imported fuel, and imported fuel costs more to deliver. For consumers, the partisan blame game offers little comfort. Drivers will experience the transition primarily as higher and more erratic prices, with limited options to reduce their exposure in the short term beyond driving less, carpooling, or shifting to more efficient vehicles where possible.
What Drivers Should Expect Next
The Benicia refinery’s April 2026 deadline is the next major inflection point for Northern California. Once that facility stops producing gasoline, the region will rely entirely on fuel trucked from the Central Valley and Southern California or shipped in via marine terminals around the Bay. Southern California faces a similar reckoning as the Phillips 66 Los Angeles-area refinery completes its shutdown, tightening supplies in a region that already contends with unique fuel specifications and heavy traffic demand. Each closure removes not just barrels of refined product but also the operational flexibility that comes from having production close to major consumption hubs.
In practical terms, drivers should prepare for a market where seasonal price swings become more pronounced, and where unplanned disruptions at the remaining refineries or along key shipping routes can trigger sharp, if temporary, spikes. Over the longer term, state policies aimed at accelerating electric vehicle adoption and expanding public transit are intended to reduce gasoline demand and, eventually, the importance of refineries altogether. But that transition will unfold over many years. In the meantime, California is entering a period in which its commitment to decarbonization coexists with a heightened reliance on imported fossil fuels, and the costs of that overlap will be felt most directly at the pump.
