Ergon Refining is investing $400 million to expand and optimize their operations in Vicksburg, a plan that will result in 20 new jobs.
The company is boosting its processing capabilities to include gas production. The planned upgrades will increase production capacity and include infrastructure connecting to its Vicksburg fuels terminal, where gas and diesel products are sold. The expansion also includes the addition of a dual cogeneration power complex, ensuring a reliable local gas supply while enhancing the efficiency and longevity of its facilities.

“$400 million is a lot of money – and this investment is another massive win for Mississippi,” Governor Tate Reeves said. “It really is an exciting time to be a Mississippian. We’re finalizing deal after deal and putting up win after win for the people who live here. Ergon is a Mississippi company growing right here at home, and their $400 million investment in Vicksburg is just the latest example of the special things happening in our state.
Ergon has 1,200 employees in Mississippi and serves customers in more than 100 countries. In 2024, the company celebrated the expansion of its Flowood headquarters, an $85 million investment that will create 200 new jobs.
The Vicksburg expansion is estimated to be complete by 2027.
“Today, there aren’t many places you’d go around the world that have not been impacted in some way by the specialty solutions produced at our Vicksburg refinery,” Ergon president and CEO Kris Patrick said. “I’m incredibly proud of the work our employees do to continue our legacy of quality products and services that make a positive global impact. As we move forward, we’re proud to collaborate with local and state partners, investing in the economic success of the place we call home.”
The Mississippi Development Authority will assist with road improvements related to the project, while the city of Vicksburg and Warren County are supporting the project, as well.
