Can hydro power mines?

Is hydropower a viable option to support mining operations’ energy needs?

Whether pumped hydroelectric, run-of-river, or small hydropower systems there is a growing need to use Africa’s vast hydro potential to boost reliability of power in remote areas, and specifically for the mining industry.

The potential is there, however, it’s not without its financial, operational and environmental challenges.

1. How can hydropower development benefit new and existing mining projects in remote parts of Africa?

2. Weighing in on the financial benefits – capex vs. opex vs. traditional diesel power supply.

3. How to incorporate hydropower into organisational corporate social responsibility for communities

4. A view on environmental impact assessment best practices for hydropower projects

5. How can hydropower projects mitigate the effects of climate change to remain a relevant source of power for mining operations?


Robert Greyling, Dams Engineer, PrENG, Knight Piésold

Robert specialises in dams and hydropower engineering. With a decade post graduate experience, he has designed all types of dams, ranging between 5m to 260m in height. His fields of expertise include flood hydrology, hydraulic design, reinforced concrete design and detailed structural dam design and analysis. He has detailed understanding in non-linear static and dynamic finite element analysis of arch, arch/gravity and arch-buttress dams and has performed a number of thermal studies for major RCC structures. He is actively engaged in hydropower and has worked on mini to large hydro installations. This includes due diligence assessments of existing installations, detailed design, transient analyses, energy simulations, economic evaluations and construction supervision of HEPP schemes in Southern and Central Africa.
