When was the last refinery built in the United States?

As of January 1, 2023, there were 129 operable petroleum refineries in the United States.

The newest refinery in the United States is the Texas International Terminals 45,000 b/cd refinery in Channelview, Texas, which started operating 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, 2023, it had a capacity of 596,000 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 626,000 b/cd as of January 1, 2023.
• In 2015, Valero expanded its Corpus Christi, Texas refinery after previous expansions, bringing its capacity as of January 1, 2023, to 290,000 b/cd.
