SATIMGE
SATIMGE is a South African hybrid energy-economic model that links the SATIM energy system model with a general equilibrium model. It assesses energy pathways, emissions, and economic impacts to support low-carbon policy and planning.
The SATIMGE modelling framework consists primarily of two components:
- A whole-energy system model called SATIM (the South African Times model),
- A whole economy Computable-General Equilibrium (CGE) model called eSAGE
This approach combines the technical detail needed for energy system optimisation with the economic analysis required to assess how energy transitions affect households, industries and the wider economy. Additional modules capture emissions from waste, agriculture and land sectors, allowing for comprehensive modelling of greenhouse gas emissions across the entire economy. The models exchange information iteratively, ensuring energy and economic projections remain consistent and aligned.
