With the closure of the Söderberg potlines at the Baie-Comeau Smelter, which use older technology that requires more energy than prebake anodes, combined with good performance at the other smelters, Alcoa Global Primary Products achieved a significant reduction in energy consumption per metric ton of aluminum produced by its Québec Smelters. Going forward, it will require an average of nearly 0.2 MWh less energy to produce one metric ton of aluminum in these smelters.
In 2015, Quebec smelters continued to improve their performance. The Baie-Comeau Smelter reduced electricity energy consumption, notably related to heating and homogenizing furnaces. The Deschambault Smelter’s reduction is related to optimal compressed air usage.
