The supply of South Africa’s energy demand is broadly determined by the energy mix as set out in The Integrated Resource Plan (IRP) 2019. Based on the 2019 IRP, Coal constitutes 43% of installed capacity followed by Wind (22.53) Solar PV (10.5) CSP (0, 76) Nuclear (2,36) and Gas and Diesel (8.1) Hydro (5.84).
Whilst the IRP is currently being reviewed, Coal, Nuclear and Gas is expected to continue to be significant contributors to SA’s base load demand in the foreseeable future, with investments in cleaner technologies to mitigate negative environmental impacts, coupled with and battery storage to neutralise and solar/wind hybrid solutions to stabilise the intermittency challenges of renewables.
