Eskom has confirmed that it will implement Stage 2 load-shedding between 9pm tonight and 6am on Friday due to "system contraints" and "depleting emergency resources".
The power utility added that the risk of load-shedding remains for tomorrow into the weekend.
"We have been using pumped storage schemes and open cycle gas turbines extensively over the past few days in order to supplement capacity, and we need to replenish these overnight," said the power utility in a statement.
Eskom said unplanned outages were reduced at 12 683MW at 13:30 on Thursday afternoon.
