Improvements in Eskom fleet performance amid lower residual demand minimised loadshedding in 2024; No new generation installed capacity was added by Eskom and REIPPs in 2024, the proposed NERSA tariff increase of 12. 74% takes the average tariff to c/kWh 195. This was a continuous, stable supply of electricity, overwhelmingly provided by coal-fired power stations, which formed the bedrock of our national grid. Load shedding is the deliberate stoppage of electrical power supply by system operators as a preventive measure to maintain system. Energy storage systems (ESS) play a critical role in supporting this energy transition, but South Africa is yet to realize its full potential. As the energy transition progresses, the financial and sustainability considerations of new ESS use cases become paramount. South Africa had 2MW of capacity in 2022 and this is expected to rise to 4MW by 2030.
