California’s refinery sector is contracting, and the explanations are usually not as difficult as operators typically counsel. When refinery homeowners announce closures, they often level to the burden of environmental rules, the prices of compliance, or fines from state companies. These elements are actual, however they aren’t decisive. The extra basic driver is demand. Gasoline consumption in California has been declining for almost a decade. That pattern alone reshapes the economics of refining, eroding margins and making long-term reinvestment in services unappealing. The closures we’re seeing now are much less about regulators pushing corporations out and extra in regards to the market pulling the ground out from beneath them.

Two main refineries in California have introduced plans to shut, and collectively they account for a big share of the state’s gasoline provide. Phillips 66’s Wilmington refinery in Los Angeles, with a capability of about 139,000 barrels per day, and Valero’s Benicia refinery within the Bay Space, with about 145,000 barrels per day of capability, are each slated to wind down operations within the subsequent two years. Refineries sometimes produce about 45% to 50% of their output as gasoline, which suggests these two services collectively present within the vary of two billion gallons yearly. With California’s whole gasoline consumption at about 13.4 billion gallons in 2024, the closures signify roughly 15% of the state’s gasoline provide, a discount that might be felt instantly in a tightly balanced market.

Governor Newsom and California lawmakers are usually not merely watching refineries shut down with out response. The state authorities has opened discussions with operators and potential patrons in an effort to maintain services like Valero’s Benicia refinery operating, and has even floated the potential of monetary or regulatory concessions to delay closures. Legislators have thought of bailout mechanisms and incentives to protect native jobs, stabilize gasoline provides, and defend tax revenues that communities rely on. These interventions are framed as a solution to handle volatility within the quick time period, however additionally they reveal the political problem of balancing an power transition with the financial realities of cities and employees tied to the refining trade.

Gasoline consumption in California peaked across the center of the final decade. In 2015, gross sales had been simply over 15 billion gallons. By 2024, that quantity had dropped to about 13.4 billion gallons. That’s an 11% decline over lower than ten years. The change has not been erratic. It has been regular, pushed by extra environment friendly inside combustion engines, larger adoption of hybrids, and the speedy improve in electrical car gross sales. The state has layered coverage on prime of these forces, with the Superior Clear Automobiles II mandate requiring 100% zero-emission passenger automobile gross sales by 2035. That provides certainty to a pattern that was already clear. With a couple of quarter of recent automobile gross sales in California now electrical, the alternative price of gasoline-powered automobiles is tipping the stability. Yearly, extra of the fleet runs on electrons as a substitute of gasoline, and yearly the gasoline market shrinks a little bit additional.

Diesel gasoline tells a unique story. In contrast to gasoline, demand for diesel has held regular. In 2017 taxable diesel gross sales had been about 3.1 billion gallons, and in 2024 the state reported 3.5 billion gallons. That represents stability reasonably than decline, and it displays the cussed nature of industrial quality transport, freight, and agricultural sectors. Vehicles, buses, and tools nonetheless overwhelmingly run on diesel. California has made progress in introducing renewable diesel and biodiesel, that are displacing petroleum diesel within the gasoline combine, in addition to electrification of some buses and vans, however the general gallons offered haven’t dropped. Which means refinery output continues to be supported on one facet of the product slate, at the same time as gasoline erodes on the opposite. The issue for refiners is that gasoline is the most important single product from most crude runs. Dropping that anchor quantity reduces the financial justification for preserving vegetation open, even when diesel stays in demand.

California’s gasoline demand is projected to proceed falling sharply over the subsequent decade as electrical car adoption accelerates and effectivity requirements tighten. With the Superior Clear Automobiles II mandate requiring 100% zero-emission car gross sales by 2035 and EVs already making up roughly 1 / 4 of recent automobile purchases, and seven% annual inside combustion car retirements, annual gasoline demand is prone to decline by round 40% or extra by the mid-2030s. This trajectory implies that by 2035 California might be burning fewer than 8 billion gallons per yr, slicing deeply into the volumes that after supported its refining sector.

When firms declare rules are forcing their hand, they’re partly proper and partly deflecting. Compliance prices and fines for emissions improve working bills. If the marketplace for gasoline had been secure or rising, refiners would take up these prices as a part of doing enterprise. As a substitute, they face a market the place volumes are falling yr after yr and the speed of decline is accelerating, which modifications the calculation. The prospect of spending tons of of tens of millions on upgrades to maintain a facility operating is difficult to justify when the primary product is dropping clients. In that setting, rules turn out to be the excuse for closures that had been inevitable anyway. The actual story is demand destruction.

Refinery closures create provide dangers, and California has a historical past of value volatility when vegetation go offline. Taking tons of of hundreds of barrels per day of capability out of the system removes a big share of gasoline provide. In a market that’s already comparatively remoted geographically, that may set off short-term shortages and value spikes till imports or different refineries compensate. These provide shocks can really feel like crises to shoppers, however they’re truly signs of transition. Disruptions are usually not failures of coverage or planning. They’re pure options of a system transferring from one dominant expertise to a different. The identical sample has performed out in different sectors when tipping factors had been reached. Coal vegetation shut down earlier than renewable power was absolutely scaled. Movie digicam factories began shuttering earlier than digital images was perfected. Typewriter factories had been deserted lengthy earlier than phrase processing was common. Petroleum refining is now experiencing the identical course of.

The suggestions loop is necessary to acknowledge. As refineries shut and gasoline turns into dearer or much less handy, electrical autos turn out to be extra engaging. Charging infrastructure is increasing, possession prices for EVs are dropping, and coverage helps are agency. Customers weigh their choices, and the stability suggestions towards electrical. As extra EVs are offered, the gasoline market contracts additional, and the case for preserving refineries open will get weaker. Gasoline stations start to shut in parallel, upkeep retailers lose clients for oil modifications and exhaust repairs, and elements suppliers see declining demand. Insurance coverage firms increase premiums on older ICE autos as dangers rise and elements turn out to be tougher to supply. Every step reinforces the erosion of the interior combustion ecosystem.

California is forward of many of the world on this respect. With aggressive mandates and powerful EV adoption, the state is crossing thresholds sooner than others. As soon as 15% to 40% of recent gross sales are electrical, as California is experiencing now, the comfort of proudly owning an ICE car begins to erode. When 40% to 80% of recent gross sales are electrical, the unraveling of the gasoline and diesel help system accelerates. California’s refineries are closing within the midst of those tipping factors. The closures are usually not anomalies or remoted missteps. They’re alerts of systemic change.

For policymakers, the temptation is to intervene, to sluggish closures or subsidize continued operation within the title of stability. That misses the bigger level. The decline of gasoline demand isn’t reversible. Attempting to carry again refinery closures delays the inevitable and misallocates public funds. The higher use of sources is to scale the brand new system. California will want extra electrical energy era, stronger transmission, expanded charging infrastructure, and planning for workforce transitions in refining and gasoline distribution. These are the investments aligned with the trajectory of demand.

The state’s expertise with diesel might be considerably totally different, because the demand plateau isn’t but a decline. However the long-term forces are comparable. Zero emission vans and buses are scaling, mandates are in place, and low-carbon fuels are taking bigger shares of the remaining market. Diesel demand will finally observe the identical curve as gasoline, simply on an extended time horizon. Refineries can not maintain themselves on diesel alone when their economics depend on massive gasoline volumes.

Hydrogen demand can even decline as these refineries shut, eradicating a big block of consumption from the state’s industrial profile, in addition to about 800,000 tons of CO2e emissions per yr associated to its manufacturing. Valero’s Benicia facility and Phillips 66’s Wilmington plant collectively eat within the vary of 100,000 to 130,000 tons of hydrogen yearly, primarily produced from pure gasoline in on-site steam methane reformers. That may be a significant fraction of California’s refinery hydrogen load, and when the services go darkish the marketplace for that hydrogen disappears with them. In my broader projection of hydrogen demand throughout sectors, refining stays the only largest client for the subsequent decade, however closures like these speed up the autumn. As gasoline and diesel demand shrinks and refineries observe, the most important present use case for hydrogen steadily erodes. The narrative of hydrogen as a progress gasoline collides with the fact that its largest industrial market is contracting in lockstep with the decline of oil.

Each refineries refine heavy bitter crude sourced from a wide range of home and worldwide producers together with Canada. As I labored out a few years in the past, they require way more hydrogen per barrel than refineries that course of gentle, candy crude, about 7.7 kg per barrel versus 1.5 to 2 kg per barrel. As world gasoline and diesel demand contracts, the heavier crude might be first off the market as a result of it’s dearer to course of. About 60% to 70% of California’s crude consumption in its 15 refineries is of heavy, bitter crude, and it’s seemingly important that two heavy, bitter crude refineries are those which have introduced closures.

California’s refinery closures are finest understood as demand-driven, not regulation-driven. Provide shocks will include them, however these are regular options of a disruptive transition. Studying the alerts appropriately is important. What is going on in California now will occur in different areas as EV penetration deepens. The state is just displaying the remainder of the world what the way forward for gasoline and diesel refining seems to be like as soon as the tipping factors of electrification are crossed.
