Rolling blackouts are costing South Africa dearly. The electricity crisis is a barrier to growth, destroys investor confidence and handicaps almost every economic activity. It has raised input costs for producers and retailers, and has triggered a new round of inflation and interest rate increases.
Any solution will obviously incur cost because it will require the adoption of new technologies, such as large-scale grid-connected solar farms that are linked to battery energy storage. But these technologies are expensive. A solar farm consisting of 50 MW of photovoltaic panels with 240 MWh of storage capacity will cost R2.6 billion. Batteries are the biggest outlay, accounting for about 40% of the total cost.
