A least-cost option for South Africa's energy mix includes a massive amount of renewables (between 50GW and 60GW) by 2030 and no new coal and nuclear, the Presidential Climate Commission has recommended. | News24_Business

The PCC says modelling shows coal and nuclear are not the least-cost option for the country's electricity system.South Africa needs between 50GW and 60GW of renewable energy by 2030, according to the climate commission.

The commission's head of mitigation, Steve Nicholls, explained that models show the least cost option for South Africa is to roll out renewables, such as solar and wind , that are supported by storage and peaking power sources like gas . These peaking plants would also be operated at a low level and not all the time.

"We have heard some public statements that nuclear is cheaper than variable renewable energy. We can't find any reference for that in the international literature," Nicholls told News24 in response to questions. Apart from the question of affordability, Nicholls said it is important to ask whether we should include small nuclear reactors in energy planning – when we are not sure of their commercial viability.Climate Future Weekly
