The U.S. Energy Information Administration (EIA) expects U.S. refinery capacity to average 17.9 million barrels per day by the end of 2025, about 3% less than at the beginning of this year. In its November Short-Term Energy Outlook, EIA forecasts that after declining for several years, refinery margins (the difference between the selling price and the cost of production) for gasoline and diesel, known as crack spreads, will remain relatively unchanged in 2025.
