When was the last refinery built in the United States?
As of January 1, 2026, there were 130 operable petroleum refineries in the United States.
The newest refinery in the United States is the Texas International Terminals 45,000-barrel per day (b/cd) refinery in Galveston, Texas, which started operating in February 2022.
However, the newest refinery with significant downstream unit capacity is Marathon's facility in Garyville, Louisiana. That facility came online in 1977 with an initial atmospheric distillation unit capacity of 200,000 b/cd, and as of January 1, 2026, it has a capacity of 617,000 b/cd, making it the third-largest refinery in the United States.
Existing refineries have added capacity through upgrades or new construction. Examples of large capacity increases include:
- In 2023, ExxonMobil upgraded its refinery in Beaumont, Texas, making it the fourth-largest U.S. refinery with a capacity of 612,000 b/cd, as of January 1, 2026.
- In 2012, Motiva upgraded its refinery in Port Arthur, Texas, making it the largest U.S. refinery with a capacity of 656,400 b/cd, as of January 1, 2026.
