South Africa’s mining sector is making a significant shift towards renewable energy to cut costs and enhance energy security.
Major companies like Anglo American, Sibanye-Stillwater, and Exxaro Resources are investing in solar and wind projects. This move aims to reduce reliance on Eskom and lower operational expenses, with investments targeting between 3GW and 5GW of renewable capacity by 2030.
Major Mining Companies Invest in Renewable Energy
South African mining companies are accelerating their transition to renewable energy. This shift is driven by the need to reduce electricity costs and emissions while maintaining competitiveness. Companies are diversifying their electricity supply through significant investments in solar and wind capacity.
Anglo American has partnered with EDF power solutions through Envusa Energy. Their renewable energy platform has developed the 520MW Koruson 2 cluster, which includes the 240MW Mooi Plaats solar project and two wind farms of 140MW each. These projects are expected to supply renewable electricity to operations like Kumba Iron Ore and De Beers.
South Africa: Key figures on renewable energy investments
- 520MW Koruson 2 cluster
- 240MW Mooi Plaats solar project
- 140MW Umsobomvu wind farm
- 140MW Hartebeesthoek wind farm
- 3GW to 5GW renewable energy capacity target by 2030

Future Plans for Renewable Energy in Mining
Mining companies are not only focused on reducing emissions but also on improving financial positions through renewable energy. Sibanye-Stillwater’s CEO emphasized that their renewable energy portfolio is a business imperative expected to deliver meaningful cost benefits.
As the industry continues to evolve, the reliance on Eskom’s grid will remain significant for baseload power. The intermittent nature of solar and wind generation necessitates a balanced approach to energy sourcing.
Next Steps for South Africa’s Mining Sector
- Continue developing renewable energy projects to meet decarbonisation goals.
- Expand partnerships for renewable energy sourcing.
- Monitor the operational performance of existing renewable projects.
South Africa’s mining companies are leading the charge towards a sustainable energy future.
