South Africa's government has announced plans to prioritize 9.6 gigawatts of battery storage and gas-fired power in its energy sector. This move aims to address the country's electricity delivery challenges, with a focus on providing power when it is needed most. The decision was made to ensure a stable and reliable energy supply, particularly in areas where the grid is constrained.
The initial allocation comprises 4.6GW of battery storage and 5GW of gas-to-power, with further wind and solar allocations to follow in a later round. Electricity and Energy Minister, Kgosientsho Ramokgopa, announced the approach, emphasizing the need for a practical solution to the country's energy challenges. The minister highlighted that building more generating plants does not guarantee that their electricity can reach customers due to grid constraints.
Grid constraints are a significant challenge in South Africa, with some renewable electricity unable to reach users due to limited network capacity. Renewable projects are often concentrated in areas where the network has little room to carry additional power, leading to curtailment. This is where batteries can help by storing electricity for later use, although their contribution depends on their location and operation.
The government is encouraging developers to consider locations with available grid capacity, such as Seriti Green's wind development in Mpumalanga. This approach aims to spread investment beyond areas where renewable resources have attracted projects faster than the network can accommodate them. By doing so, the government hopes to optimize the use of existing infrastructure and reduce the strain on the grid.
Gas plants will play a crucial role in supplying electricity when renewable output falls or demand rises. Their usefulness will depend on fuel availability and cost, as well as connections to ports, pipelines, and the grid. The procurement assessments will consider these requirements, along with construction schedules and the plants' ability to adjust output.
The Department of Electricity and Energy has outlined a procurement programme covering the 2026–2037 planning period. The programme proposes a state-led Power Parks programme aimed at lowering entry barriers for emerging developers and coordinating projects with supporting infrastructure. While this is a stated objective, it remains to be seen how it will be implemented and what impact it will have on the energy sector.
The announcement provides insight into the government's intentions, but it does not establish when the full 9.6GW will become available or what customers will pay for its services. For businesses planning around more dependable electricity, the government's plans offer a sense of direction, but further details are needed to understand the full implications of the 9.6GW energy push.
