Challenges of Planning Future High Voltage Power Systems Networks

Growth and development within South Africa has led to an increase in the demand for electricity. This has resulted in the expansion of electric power networks and this evolution to the current power system networks. Thus far, there have been challenges, both technical and non-technical, however going forward there is likely to be challenges that are more complex. We are aware that these networks will change and the question is then how, when and how quick would they change. The paper deals with planning future high voltage power system networks. These supply cities, municipalities, large power users but also smaller communities and rural networks. The increase in electricity tariffs, load-shedding, introduction of renewable energy and the drive towards clean energy sources are among the key aspects that would have in impact on the energy sector. Policy and regulatory changes are will effect have signify key to facilitate change and can either hinder or promote these changes and the evolution of the network.
