SATIMGE Model Adaptation for South Africa

The Energy Systems Research Group (ESRG) in South Africa has developed the SATIMGE model to support the country’s energy transition, integrating the TIMES model with the eSAGE Computable General Equilibrium model. This tool provides comprehensive analyses of trade-offs for reducing reliance on coal, which currently supplies 90% of South Africa’s primary energy. SATIMGE is actively used in policy processes, including the 2030 and 2035 NDC updates. The team is enhancing the model’s power sector detail with hourly demand projections and spatial analyses to optimize renewable integration, making it a critical resource for sustainable planning.
