Superior Refinery Wisconsin to Reopen in 2023
In 2018 an explosion at Wisconsin’s only oil refinery injured dozens and caused thousands to evacuate. Five years later, the refinery is set to reopen following a $1.2 billion rebuild and multiple safety recommendations from federal agencies. In March 2023 the refinery, now owned by Cenovus Energy, began introducing crude oil aiming to resume full operations by the end of June.
