South32 and Eskom in Talks over Hillside Smelter Power Supply Following Closure of Mozal

Why It Matters

Securing reliable, affordable power is essential to keep Hillside operational, preserving thousands of jobs and a key aluminium supply chain, while showcasing South Africa’s drive toward industrial competitiveness and a lower‑carbon energy mix.

Key Takeaways

• Mozal closure cut 4,000 jobs, one‑third Mozambique manufacturing
• Hillside aims for new power deal by 2031
• Eskom offers flexible tariffs, renewable and nuclear options
• Hillside supports 3,650 direct jobs, 29,000 total economy
• 720,000 tonnes aluminium output fuels South African downstream industry

Pulse Analysis

The abrupt shutdown of South32’s Mozal smelter in Mozambique underscored the vulnerability of energy‑intensive industries to unstable power contracts. With 4,000 workers displaced and a significant portion of the country’s manufacturing capacity idle, the closure sent a clear signal that reliable electricity is a non‑negotiable prerequisite for large‑scale metal production. This backdrop has accelerated talks between South32 and South Africa’s state utility, Eskom, as both parties seek to avoid a repeat scenario at the Hillside facility.

Hillside Aluminium, a cornerstone of South Africa’s industrial landscape, churns out roughly 720,000 tonnes of aluminium each year, feeding downstream manufacturers ranging from automotive to packaging. The plant sustains 3,650 direct jobs and underpins an estimated 29,000 jobs throughout the broader economy. By establishing a joint working group, South32 and Eskom aim to lock in a power agreement by 2031 that balances cost‑competitiveness with the utility’s evolving generation mix, which now includes greater renewable and nuclear capacity. Eskom’s willingness to negotiate more flexible tariffs reflects a strategic shift to retain heavy‑industry customers while managing its own fiscal pressures.

Beyond the immediate stakeholder benefits, the negotiations signal a pivotal moment for Southern Africa’s energy policy. A stable, lower‑carbon power supply for Hillside could serve as a template for other energy‑intensive sectors, encouraging investment and reinforcing the region’s position in the global aluminium market. Moreover, aligning industrial demand with Eskom’s clean‑energy roadmap supports South Africa’s broader climate commitments, potentially unlocking financing incentives and fostering a more resilient, diversified economic future.
