California operates the fifth largest oil refining network in the Western Hemisphere, a complex system that quietly powers the state’s economy and daily life. Understanding how many oil refineries are in california requires looking beyond a simple number, as the landscape is defined by scale, location, and strict regulation. This overview provides a clear picture of the facilities that transform crude oil into the fuels and products millions of people rely on.
Current Refinery Count and Capacity
The direct answer to how many oil refineries are in california is that there are 14 operating refineries. These facilities are not distributed evenly across the state but are concentrated in regions with deep industrial history and major transportation hubs. Collectively, they process approximately 2 million barrels of crude oil per day, giving California a refining capacity that ranks among the top states in the nation. This capacity is essential for meeting the demands of a large population and a significant transportation sector.
Geographic Distribution
The geography of California’s refineries tells a story of ports and historical industrial zones. The largest cluster is found in the Los Angeles Basin, including refineries in Wilmington, Carson, and Torrance, which benefit from proximity to imported crude shipped through the Port of Los Angeles. Another major concentration sits in the San Francisco Bay Area, with refineries in Richmond and Martinez, connected to the Port of Richmond. Smaller operations are located in Bakersfield and the Central Valley, closer to inland production areas.

Central Valley: Bakersfield.
Regulation and Environmental Context
How many oil refineries are in california is a question often answered alongside discussions of environmental policy. California’s refineries operate under the strictest emissions regulations in the United States, managed by the California Air Resources Board (CARB). This framework means that refineries here are among the most technologically advanced for pollution control, though these compliance costs contribute to the state’s historically higher fuel prices. The regulatory environment continuously pushes the industry toward cleaner processes and lower carbon intensity.
Economic and Strategic Importance
Beyond fuel, these 14 refineries are critical infrastructure supporting jobs and state revenue. They employ thousands of skilled workers in high-wage positions and generate significant tax income that funds public services. The state’s refining sector is also strategically vital, ensuring a degree of energy resilience and reducing dependence on out-of-state fuel sources during supply disruptions. Maintaining this infrastructure is considered essential for California’s energy security.
Challenges and Future Outlook
The landscape of how many oil refineries are in california exists in a state of flux, shaped by evolving market forces and climate goals. Some facilities have closed permanently, while others have adapted by processing different crude streams or blending biofuels. Refinery expansions face rigorous scrutiny, and the long-term trajectory points toward a gradual transition in business models. This evolution reflects the broader shift within the energy sector as California pursues a lower-carbon future.
Key Operational Metrics
To grasp the scale of these facilities, it is helpful to view specific metrics. The table below outlines the approximate daily processing capacity of the major refinery clusters, illustrating where the highest volume operations are located.
