MONCKS CORNER, S.C. - Santee Cooper and Century Aluminum have agreed to an extended service agreement to provide additional power to Century's Mt. Holly aluminum smelter through 2031.

The deal allows Century to reopen an idled potline, increase plant capacity by 25% and bring over 100 additional high-paying jobs to the Charleston region. Santee Cooper has provided electricity to the Berkeley County plant since it came online in 1980.

"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. "Santee Cooper is proud to be the power behind Century, supporting the quality products they produce, the important contributions they make to our community, and the quality jobs they provide to our neighbors. We're pleased to be part of this expansion and look forward to working together for many more years."

Century Aluminum CEO Jesse Gary said, "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. We are excited to continue our relationship as we increase economic opportunity and prosperity for South Carolinians together."
