JOHANNESBURG/CAPE TOWN, Oct 17 (Reuters) – South Africa will experience power cuts for a third day on Friday but is unlikely to be affected through the weekend as more generating units return to service, utility Eskom acting chief executive said on Thursday.
Eskom has since Wednesday been forced to impose power cuts for the first time in around seven months, after a number of its generating units broke down.
The power cuts show the challenge facing President Cyril Ramaphosa in rescuing the state company, which has been beset by financial and technical problems, and putting further pressure on the economy.
Eskom cut 2,000 megawatts (MW) of power from 9 a.m. (0700 GMT) until 11 p.m. (2100 GMT) on Thursday on a rotational basis across the country. The process is known as load-shedding.
Eskom Acting Group Chief Executive Jabu Mabuza said the utility will cut 1,000 MW of power from the grid on Friday, and thereafter the utility did not anticipate further power cuts.
“The system remains constrained and vulnerable,” Jabu Mabuza told journalists.
“However, some generating units have already returned to service and we are expecting more units to return to service over the next few days, which lessens the probability of load shedding towards the weekend.”
Mabuza said the decision was necessary to protect the grid from total collapse after unplanned outages.
“Our objective is not to implement load shedding. If we have to as a matter of last resort in order to protect the integrity of the system, we aim to do so at minimal levels, in the shortest duration possible,” he said.
Debilitating power cuts in February and March pushed first-quarter economic growth into contraction and raised the likelihood of South Africa losing an investment-grade rating.
Moody’s is the last of the big three credit rating agencies to have an investment grade rating on South Africa and is due to deliver its latest credit review on Nov. 1.
