Stage 6 load-shedding will continue for a while as Eskom struggles to meet the higher demand for electricity as a result of the cold weather.

Power utility spokesperson Daphne Mokwena says although higher demand was expected, it has exceeded their forecast.

“Eskom is obliged to carry generation reserves to cater for unforeseen events. These reserves were used on Monday and Tuesday to buffer the effects of the cold weather. Unfortunately, due to the failure of additional generation units since Sunday, the reserves have been depleted and can no longer buffer the lingering effects of the cold weather and make up for the lost generation capacity,” she explains.

Mokwena says that as a result, stage 6 power cuts will be implemented continuously this weekend – and until depleted reserves recover enough to warrant a reprieve.

“Breakdowns are currently at 17 679MW of generating capacity, while the generating capacity out of service for planned maintenance is 3 090MW,” she adds.

Eleven generating units (one each at Grootvlei, Hendrina, Lethabo and Tutuka, two each at Arnot and Matla, and three at Kriel) have been taken out of service since Sunday.

In addition, there have been delays in returning three generating units to service (one at Kendal and two at Tutuka).

“Eskom teams are working tirelessly to return these generating units to service. It is anticipated that eight generating units will be returned to service in the next few days,” Mokwena says and appeals to the public to lower their demand.
