In recent years a competitive management of energy systems technologies has been a major challenge to South African organizations including Eskom, the National Energy Regulator as well as government departments such as the Department of Energy and Department of Transport. Eskom has been a monopoly electricity utility company in South Africa for nearly 100 years. As a result of the Eskom monopoly and regulations which prevented the entry of independent power producers, the energy mix in South Africa has effectively been fossil fuel based central generation technologies, namely coal and nuclear. In the transport sector the predominant suppliers are foreign oil companies such as Shell, Total, BP, Caltex and Mobil, which provide petroleum and diesel. Local transportation fuel suppliers are PetroSA and Sasol. Moving forward the government of South Africa is beginning to open up the power generation space to include renewable energy options. The establishment of an independent power market trading entity will allow customers to benefit from multiple generation sources. The Renewable Energy Feed-In Tariff (REFIT) will be among the tools that the energy market regulator will use in the management and selection of electricity generation technology. However, if an energy solution is to fit into the South African context, it must support the goals of sustainability of society, which means that the price of the commodity cannot be the sole criteria for purchase of generation output. This paper proposes a new energy market management model that takes into account technical, financial and socioeconomic measures that can be used by a pool regulator in deciding which power producer from which to procure electricity. The model focuses on a reliable and sustainable electricity market as its key pillar to promote energy security.
