South Africa’s flagging economy could face a second recession in as many years due to a new wave of nationwide power cuts. Eskom Holdings, the State-owned power utility seen by Goldman Sachs Group as the biggest threat to the country’s economy, started a fifth day of rolling blackouts on Monday due to further losses of generating capacity at its plants. While the power cuts are implemented to prevent a collapse of the electricity grid, they have a debilitating effect on the economy by curtailing mining activity and factory output and causing crippling traffic delays.
