South Africa faces highest level power cuts as generation units fail

On Saturday, Eskom applied Stage 3 power cuts, effectively cutting 3,000 megawatts to the national grid.

"Of the 10 units that we lost overnight we have essentially returned six units," Dan Marokane, Eskom group chief executive officer told reporters on Sunday.

He said five to six units were expected to become operational during the course of the day, bolstering the 3,200 MW of capacity recovered overnight.

"We anticipate to get out of this stage by the end of the week," he said, adding that given the pace of recovery Eskom would consider dialling down its power cuts by Monday.

Regular breakdowns at Eskom's fleet of ageing coal-fired plants, providing the bulk of electricity in Africa's most industrialised economy, are often the cause of loadshedding - an incremental system where stage 1 sees 1,000 MW cut from the system, with stage 6 the highest implemented to date.
