Frequently Asked Questions

When was the last refinery built in the United States?

There were a total of 135 operable petroleum refineries in the United States as of January 1, 2018.

The newest refinery in the United States is the Magellan Midstream Partners LP 42,500 barrels per calendar day (b/cd) condensate splitter in Corpus Christi, Texas. Condensate splitters are distillation units that process condensate, which is lighter than crude oil. Splitter capacity is included as atmospheric distillation units in U.S. Energy Information Administration (EIA) data. The Magellan Midstream Partners LP unit, which began operating in 2017, was operable but not running at the start of the year, so its capacity was listed as idle in the 2017 Refinery Capacity Report. See the link below in Learn more to the most recent Refinery Capacity Report.

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, 2018 had a capacity of 556,000 b/cd.

Capacity has also been added to existing refineries through upgrades or new construction. Some recent examples of large increases include:

  • In 2012, Motiva upgraded its refinery in Port Arthur, Texas, making it the largest U.S. refinery, with a capacity of 603,000 b/cd as of January 1, 2018.
  • In 2015, Valero again expanded its Corpus Christi, Texas refinery after previous expansions, bringing its capacity as of January 1, 2018 to 275,000 b/cd.
