Refining Capacity by State FAQ
Which state has the most refining capacity?
Texas, with 6.13 million barrels per calendar day of operable crude distillation capacity as of January 1, 2026, or 33.8% of the US total of 18.16 million. Louisiana (3.01 million) and California (1.50 million) follow.
How much US refining capacity is on the Gulf Coast?
PADD 3, the Gulf Coast region, holds 9.88 million barrels per calendar day, or 54.4% of US capacity, across 58 refineries. That concentration is why Gulf hurricanes can disrupt fuel supply nationwide.
How many oil refineries are there in the US?
The EIA counted 130 operable refineries as of January 1, 2026, against 141 in 2016. Total capacity was 18.16 million barrels per calendar day, below the 18.98 million peak of 2020.
What is the difference between capacity and utilization?
Capacity is how much crude a refinery can process; utilization is the share of that capacity actually running. The current weekly national utilization rate is on the EIA fundamentals and refineries pages.
What is a "barrel per calendar day"?
The EIA reports operable atmospheric crude distillation capacity per calendar day, the amount a refinery can process on average over a year, allowing for downtime. Its stream-day figure, the rate on a day of continuous operation, is higher.
