South32 Idles Mozambique Aluminum Smelter as Power Costs Bite

South32 Ltd.'s decision to idle its Mozambique aluminum smelter represents a watershed moment for industrial investment in Southern Africa, exposing the continent's critical vulnerability in energy infrastructure and raising serious questions about the viability of large-scale manufacturing operations across the region. The Mozal smelter, representing the second-largest aluminum production facility in the Southern Hemisphere, has ceased operations following unsuccessful negotiations to secure reliable and cost-competitive electricity supply. The facility's closure—triggered by the expiration of affordable power agreements—underscores a fundamental challenge facing multinational investors: African governments' inability to deliver consistent energy infrastructure at commercially viable rates. For European investors and entrepreneurs, this development carries profound implications. The Mozambique shutdown signals that even established industrial players with significant capital investment face insurmountable operational obstacles when energy security deteriorates. South32's decision wasn't driven by commodity price volatility or operational inefficiency, but rather by a single variable—power availability and cost—that should theoretically fall within a government's control. Mozambique's electricity sector has faced mounting pressure from aging infrastructure, underinvestment, and competing demands from growing urban populations and other industrial consumers. The Cahora Bassa hydroelectric dam, historically the backbone of the country's power supply, has experienced reduced output due to prolonged droughts and deferred maintenance. As
