The report uses the SATIMGE modelling framework to compare a least-cost Reference Case against various Policy Scenarios and an 'Ideal Energy Scenario' for South Africa. The Ideal Energy Scenario targets net zero CO2 by 2050 with a cumulative GHG limit of 8 Gt CO2-eq, featuring a systemic shift to 80% public transport, expanded social provisioning for low-income households (including 6.5 million solar water heaters), and a domestic clean energy manufacturing sector with 85% local content. Results indicate that while total system investment costs increase, an affordable and socially inclusive transition is possible, with energy sector employment increasing due to localisation measures, despite a slight relative decline in economy-wide employment compared to the Reference Case.
