This paper analyses the future electricity system of South Africa based on an energy system modelling approach. The resource potential of solar technologies is evaluated and then their interaction in the South African electricity system is assessed by using a fundamental electricity system modelling (ENTIGRIS-SouthAfrica). The model is used to analyse the South African long-term electricity generation portfolio mix, optimized site selection and required transmission capacities until the year 2050. Hereby especially the location and grid integration of solar technology (PV and CSP) and wind power plants can be analysed. A potential energy scenario is calculated to show a potential pathway of using a high share of renewable energy technologies in the electricity system by 2050.
