The African mining industry is undergoing a significant transformation, driven by the need for sustainable energy solutions to support its operations. As the sector continues to play a crucial role in driving economic growth, mining companies are increasingly investing in renewable energy infrastructure to reduce their carbon footprint and enhance energy security.
Key Developments in Renewable Energy for Mining
Northam Bolsters Power Supply
Northam, a leading mining firm, has signed a power purchase agreement (PPA) for 140 MW of wind power to support its platinum group metals operations in Limpopo, South Africa. This deal follows an earlier PPA signed in October 2024 for an 80 MW solar power facility to supply the company’s Zondereinde mine.
Richards Bay Minerals Expands PPA Portfolio
Richards Bay Minerals, a subsidiary of Rio Tinto, has signed its third PPA with Red Rocket, securing 230 MW of electricity from Red Rocket’s 380 MW Overberg Wind Farm. This agreement increases the company’s total contracted renewable energy supply to 500 MW and supports Rio Tinto’s commitment to reducing emissions by 50% by 2030.
Other Mining Companies Invest in Renewables
Other mining companies across Africa are driving large-scale energy projects to secure a stable power supply. These include:
- Ivanhoe Mines: Completed a 5 MW solar facility in Q1 2025 to support its Platreef PGM mine.
- Impala Platinum: Signed a five-year PPA with Discovery Green to supply wheeled renewable energy to its Impala Refineries operation.
- Trafigura: Developing a 2 GW initiative to power Angolan mines.
- First Quantum: Set to commission a 430 MW project in Zambia in 2025.
- Tronox Holdings: Plans to roll out 400 MW of energy projects in South Africa by 2027.
- CMOC: Preparing a 200 MW energy project in the DRC, set for commissioning by 2028.
African Mining Week: Showcasing Energy Security and Investment Opportunities
The upcoming African Mining Week conference will highlight the continent’s investment opportunities emerging from the mining-energy nexus. The event will emphasize the growing demand for stable, sustainable energy solutions as miners continue to invest in energy infrastructure. With key milestones in energy security for the sector on display, African Mining Week is set to be a premier platform for industry stakeholders to explore lucrative opportunities within Africa’s independent power markets.
