U.S. Refinery Capacity by State: Operable Crude Distillation Capacity and Refineries
On January 1, 2026, U.S. refineries had 18,160,493 barrels per calendar day (b/cd) of operable atmospheric crude oil distillation capacity, the first processing step for crude oil, at 130 operable refineries. Capacity was 1.4% lower than a year earlier. The highest January 1 figure in EIA's series (from 1982) was 18,976,085 b/cd in 2020.

Texas (33.8%), Louisiana (16.5%) and California (8.3%) had the most capacity. The Gulf Coast district (PADD 3) held 54% of the U.S. total. The number of operable refineries went from 301 in 1982 to 130 in 2026, while capacity changed +1.5%, so average capacity per refinery rose from 59,434 to 139,696 b/cd. There were 141 operable refineries ten years earlier, in 2016.
Arizona, Florida, Georgia, Maryland, Missouri, North Carolina, Nebraska, New York, Oregon and Virginia reported operable capacity in earlier years but none on January 1, 2026.

| U.S. Energy Information Administration | Operable atmospheric crude oil distillation capacity and number of operable refineries, as of January 1 (petroleum/pnp/cap1) | barrels per calendar day (b/cd); count | 1982–2026 | 2026 |
EIA publishes these figures annually in its Refinery Capacity Report, as of January 1. Barrels per calendar day reflects capacity over a full year including downtime; million-b/cd figures are b/cd ÷ 1,000,000.
