"But it depends on what happens on the systems so we cannot exclude any up in load-shedding levels as such. We are not preempting beyond stage 6 at this point in time. It depends on what happens as we move along," the power utility's Isabel Fick says.

An unprotected wage strike by workers has put a severe strain on operations at Eskom's power plants.

The walkout prompted the power utility to this week implement stage 6 load-shedding.

Stage two load-shedding will now continue throughout the weekend.

In a press briefing yesterday, Eskom's Fick said there have also been no adverse effects on the transmission grid.

Eskom spokesperson, Sikonathi Mantshansha, says eThekwini Municipality still remains exempt from the load-shedding.

"That is because of the continuous problems, they are still trying to restore their network, and load-shedding at this point might cause additional problems for the customers."
