Renewables-heavy mix is South Africa’s cheapest option, yet another study confirms

A new, independently produced techno-economic model of South Africa’s cost-optimal power generation mix in 2040 outlines a system where 69% of the electrical energy is produced from onshore wind and solar photovoltaic (PV) generators, supported by batteries and gas-fired generators. Conducted by the Frankfurt Institute for Advanced Studies (FIAS), the study concludes that there will be no need for the addition of new coal or nuclear power stations beyond what is already installed.
