Santee Cooper strives to do more than just deliver reliable power and water. We’re invested in helping the communities we serve grow and thrive.
In the fall of 2025, Santee Cooper and Century Aluminum agreed to an extended service agreement to provide additional power to Century’s Mt. Holly aluminum smelter through 2031.
This agreement brings a boost to the Lowcountry and to South Carolina’s economy. Century Aluminum plans to restart an idled potline at its Berkeley County facility, increasing plant capacity by 25% and creating more than 100 new high-paying jobs in the Charleston region. It’s a powerful example of how strong customer relations can drive long-term growth and shared success.
“Century Aluminum is a major contributor to economic prosperity in Berkeley County and the entire Charleston region, and they are playing a leading role in regenerating America’s aluminum industry,” said Jimmy Staton, Santee Cooper President and CEO. “We’re pleased to be part of this expansion and look forward to working together for many more years.”
Santee Cooper has supplied electricity to the Mt. Holly plant since it began operations in 1980. Over more than four decades, that relationship has evolved alongside the needs of this modern industrial customer—demonstrating Santee Cooper’s ability to listen, adapt, and deliver innovative solutions that support both reliability and economic development.
“I would like to thank the entire Santee Cooper team for their efforts in reaching this power extension to allow us to restart the idle capacity at Mt. Holly, said Century Aluminum CEO Jesse Gary. We are excited to continue our relationship as we increase economic opportunity and prosperity for South Carolinians together.”
By working collaboratively with large industrial customers like Century Aluminum, Santee Cooper continues to deliver dependable service, support innovation, and operate with transparency to create value for customers, communities, and stakeholders across South Carolina.
