Johannesburg – Eskom on Tuesday ramped up load-shedding to Stage 5.
In a power alert, Eskom said: “Stage 5 load-shedding will be implemented from 12H00 this afternoon until 21:00 tonight.
“Thereafter Stage 6 load-shedding will be implemented until 05H00 tomorrow morning.”
The struggling power utility said in the last 24 hours six generating units broke down.
Exacerbating the problem was that two units – at Duvha and Hendrina – had not returned to service.
Eskom said there was also a delay in returning generating units to operations at Kendal, Grootvlei, and Kriel power stations.
