Galveston Bay Refinery

Galveston Bay Refinery



Our Galveston Bay refinery is in Texas City, Texas, on Galveston Bay, off the entrance to the Houston Ship Channel. In 2018, Galveston Bay merged with MPC’s former Texas City refinery into a single world class refining complex with a crude oil refining capacity of 631,000 barrels per calendar day (bpcd).

The refinery can process a wide variety of crude oils into gasoline, distillates, natural gas liquids and petrochemicals, heavy fuel oil and propane.  Products are distributed via pipeline, barge, transport truck, rail and ocean tanker. The refinery has access to the export market and multiple options to sell refined products.

An on-site co-generation facility currently has 1,055 megawatts of electrical production capacity and can produce 4.3 million pounds of steam per hour. Approximately 45 percent of the power generated in 2018 was used at the refinery, with the remaining electricity being sold into the electricity grid.
