Mining is therefore set to expand in the coming years. Africa's power generation capacity is 80 GW, of which 40GW is in South Africa and 23 GW is allocated to mining projects, mainly in Sub-Saharan Africa. Thus, about 50% of the electricity production in Sub-Saharan Africa is generated by the mining sector.
