New analysis conducted using updated cost assumptions for solar photovoltaic (PV), onshore wind and batteries shows that the share of renewable energy in an electricity mix that would also be the least cost for South Africa could grow to above 90% by 2050. Such a portfolio, the study indicates, will be 30% cheaper than the generation mix currently outlined in the Draft Integrated Resource Plan (IRP) Base Case, published by the Department of Energy (DoE) in November 2016.
