Meridian undertook a detailed analysis of the role for gas-powered generation in the South African power system. This study built on Meridian’s own power system analysis conducted with the Council of Scientific and Industrial Research (CSIR) as well as interpretation of results from peer studies conducted by the National Business Initiative and UCT’s Energy Systems Research Group. The analysis included a detailed assessment of the gas supply alternatives, associated value chains and integrated this with the power system needs from the modelling results to conclude that the rational economic role for gas is very small and limited to a partial supply of the peaking demand.
