In March 2012, EGA started seven test cells to validate the new D18+ cell technology. Designed with the latest technological advances to upgrade the original D18 Potlines, the test cells quickly met their design targets with specific energy of 12.75 DCkWh/kg Al and AE frequency <0.02 /cell/day. After the successful validation, a project was commenced in August 2015 to upgrade the original D18 potlines to the newly developed D18+ cell technology. Unlike previous capacity expansion by EGA, the D18+ project required construction to occur within the existing potrooms, which continued to operate while the upgrade was underway.Despite the challenges that this involved, full potline conversion was successfully achieved ahead of schedule and without injury. Through increased amperage to 235 kA and higher efficiency EGA production capacity will be increased by 23.3 kT per annum. Further conversion of 272 cells to D18+ in Potline 3 will commence in September 2016.
