In its 2014  U.S. petroleum refinery update the U.S. Energy Information Administration - EIA - informs that capacity edges up, ownership shifts. Details as follows:

As of January 1, 2014, there were 139 operating refineries and three idle refineries with total atmospheric crude oil distillation capacity (ACDU) of 17.9 million barrels per calendar day (bbl/cd), a 101,000-bbl/cd increase in capacity from January 1, 2013. In 2013, four refineries changed ownership, continuing the trend of a handful of sales each year. This information is detailed in EIA's recently released 'Refinery Capacity Report', which surveys U.S. refinery ownership and capacity annually at the start of each year.

Valero Energy Corporation remains the largest U.S. refiner, with total ACDU capacity of more than 1.9 million bbl/cd. Exxon Mobil Corporation is second at almost 1.9 million bbl/cd. With the purchase of the Texas City refinery from BP, Marathon Petroleum Corporation became the third-largest refiner, with a capacity of 1.7 million bbl/cd. Marathon is calling the refinery Galveston Bay to distinguish it from the much smaller Texas City refinery Marathon had already owned.

Phillips 66 fell to fourth-largest and Motiva remained fifth-largest. Combined, these five companies own 45% of total U.S. refining capacity. With its purchase of the Carson refinery, Tesoro became the largest refiner on the West Coast. The concentration of refinery ownership in other regions is mostly unchanged from last year.

PBF Energy Corp and Marathon Petroleum still lead the East Coast and Midwest in refining capacity, respectively. Valero has the most capacity in the Gulf Coast region, and Suncor has the most capacity in the Rocky Mountains.

In 2013, Nustar Refining sold its San Antonio, Texas, refinery (16,112 bbl/cd) to Calumet Specialty Products Partners. BP sold two refineries in 2013, one in Texas City, Texas (451,000 bbl/cd), to Marathon Petroleum Corporation, and a second in Carson, California (251,000 bbl/cd), to Tesoro Corporation. Tesoro sold its Ewa Beach (Kapolei), Hawaii, refinery (93,500 bbl/cd) to Par Petroleum Corp.
