Abstract Scope Retrofitting older aluminum reduction cell line is an effective way to extend the productive life of an aluminum smelter. With the modification of busbar system, cathode lining design and superstructure design, the GP320 aluminum reduction cell can achieve the target of both current creep and energy saving. In July 2020, a retrofitted GP320 cell line was started up (which was initially designed in 2002 and started up in 2003), and the current has been increased to 340kA. Until June 2022, all the cells are operating at stable, high-efficient condition. The retrofit has reached the design target and shown a great example for the future of older cell lines.
