Global aluminium production is being fundamentally reshaped by electricity, not just its cost, but its availability, source and regulatory pressures. Smelting aluminium has always been electricity\u2011intensive, but recent market stress is forcing companies to rethink where and how they operate, with implications that ripple across supply chains and long\u2011term output.<\/p>\n\n\n\n
In 2023-24, primary aluminium smelting consumed well over 900 terawatt\u2011hours<\/strong> of power to produce roughly 70-72 million tonnes<\/strong> of metal, a footprint larger than many national grids. That intensity has exposed vast disparities in smelter competitiveness and is accelerating structural change in global capacity.<\/p>\n\n\n\n The heart of the challenge is economic. Aluminium smelting operates at a huge scale: the Hall\u2013H\u00e9roult electrolysis process that extracts aluminium from alumina relies on continuous access to cheap, reliable electricity. Even small increases in power costs squeeze margins sharply because energy is one of the largest input costs in the business.<\/p>\n\n\nElectricity costs are redefining smelter viability<\/h2>\n\n\n\n
