The question, then, is what has driven refinery capacity down, and therefore profit margins and gas prices up?
The multifaceted story involves inaccurate predictions of demand, extreme weather events, disinvestment in new capacity, and yes, refineries taken offline in Russia during the war. But the ongoing story in refineries, according to Diana Moss of the American Antitrust Institute, is one of rampant consolidation.
“There has been a dramatic loss of numbers in physical refineries since the early 1980s,” Moss explained, pointing to Energy Information Administration statistics. Operable refineries narrowed from 301 in 1982 to 129 in 2021, and the reductions were even more pronounced in the diesel heating oil–reliant Northeast, with a 74 percent reduction over the same time frame. An Oil & Gas Journal article from 2015 demonstrates 20 years of consolidation, from 26 major refinery players to 11. In California, two firms control half the refinery capacity.
