[South32 to Close Mozal Aluminium by March 2026, Threatening Mozambique’s Economy]
South32 has announced that its Mozal Aluminium smelter in Mozambique, the country’s largest industrial employer with over 2,500 workers, will be placed on care and maintenance when its electricity supply agreement expires at the end of March 2026. This closure could have major economic repercussions, as the smelter contributes 4% to Mozambique’s GDP and 15% of its goods exports. An additional 21,000 indirect jobs are estimated to be tied to Mozal’s operations.
The mining group cited the prolonged failure—over six years—of securing a new electricity agreement with the Mozambique government, Hidroeléctrica de Cahora Bassa (HCB), and Eskom. Negotiations have been complicated by tariff disputes and the structure of power transmission agreements, especially as two-thirds of Cahora Bassa’s electricity is exported to South Africa. A worsening drought has also reduced HCB’s capacity to supply hydroelectric power, increasing uncertainty over future supply.
Mozal produced 318,000 tons of aluminium in 2024, but output is expected to decline to 240,000 tons in FY2026 as pot relining halts and the smelter winds down. South32 will recognize a $372 million impairment on Mozal, reducing its book value to $68 million.
Analysts warn that the case underscores the vulnerability of energy-reliant industries in Africa and the urgent need for more robust and reliable power infrastructure to attract and retain maj
