Data source: U.S. Energy Information Administration, Refinery Capacity Report
Note: Data reflect refinery capacity as of January 1 of the indicated year.
According to our latest annual Refinery Capacity Report, U.S. operable atmospheric distillation capacity, the primary measure of refinery capacity, totaled 18.4 million barrels per calendar day (b/cd) on January 1, 2025—essentially flat compared with last year.
We publish two measures of refinery capacity in the report: barrels per calendar day and barrels per stream day. Calendar day capacity represents the operator’s estimate of the input volume that a distillation unit can process in a 24-hour period under usual operating conditions, factoring in both scheduled and unscheduled maintenance. The calendar day capacity reported by companies may differ slightly from other published figures because of differences in estimation methods.
