The South Africa model is uncalibrated. It has not been through TransitionZero’s model calibration standard, so results have not been checked against historical capacities, generation, emissions, or trade. Use it for exploratory analysis out of the box, and calibrate it for modelling work.

Capacity Expansion

  • Base year: 2023
  • End year: 2050
  • Spatial resolution: National (1 node only)
  • Temporal resolution:
    • Low resolution (24-hourly and yearly) - 1 timeslice
    • Medium resolution (3-hourly and 3-monthly) - 32 timeslices

​
Dispatch

  • Spatial resolution:
    • National (1-node)
  • Temporal resolution:
    • High resolution (hourly and single year) - 8760 timesteps
