South African state utility Eskom said it would implement "Stage 2" rotational power cuts between 1600 and 2400 local time (1400 and 2200 GMT) on Tuesday, due to a shortage of generation capacity.
LONDON —
Eskom in a statement also warned that there was a high probability of power cuts on Wednesday and Thursday evenings.
Earlier this month Eskom said in a statement that there had been a delay returning several generation units to service, while others had broken down.
Eskom has an aging power station fleet comprised mainly of coal plants that are highly prone to faults.
Government efforts to add additional capacity have been slow, and this year a record among of electricity is set to be cut from the grid.
