When was the last refinery built in the United States?

A total of 135 operable petroleum refineries were operable in the United States as of January 1, 2019.

The newest refinery in the United States is the Targa Resources Corporation 35,000 barrels per calendar day (b/cd) condensate splitter in Channelview, 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 Targa unit, which began operating in 2019, was operable but not running at the start of the year, so its capacity is listed as idle in the 2019 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, 2019, it had a capacity of 564,000 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 607,000 b/cd as of January 1, 2019.
• In 2015, Valero again expanded its Corpus Christi, Texas, refinery after previous expansions, bringing its capacity as of January 1, 2019 to 290,000 b/cd.
