Frequently Asked Questions

When was the last refinery built in the United States?

There were 140 operable petroleum refineries in the United States as of January 1, 2015.

Two new simple refineries began operating in early 2015:

  • The 19,000-barrel-per-calendar day (b/cd) Dakota Prairie facility in Dickinson, North Dakota
  • The 42,000 b/cd Kinder Morgan condensate processing facility on the Houston, Texas, ship channel, with plans to double that capacity by the end of 2015

The newest complex refinery with significant downstream unit capacity began operating in 1977 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, 2015 had capacity of 522,000 b/cd.

Capacity has also been added to existing refineries through upgrades or new construction. The most recent examples are:

  • In 2012, Motiva upgraded its refinery in Port Arthur, Texas, making it the largest refinery in the United States with a capacity of 603,000 b/cd as of January 1, 2015.
  • In 2009, Marathon upgraded its Garyville, Louisiana refinery.  As of January 1, 2015, the capacity (b/cd) is more than double its original 1977 capacity.
