Stage 3 of loadshedding is set to kick off from 5pm on Friday, Dan Marokane, Chief Executive Officer of Eskom, said in a media briefing on Friday afternoon.
He said this is a temporary setback, in an effort to build up reserves, which could otherwise, run out by next week.
“Loadshedding is an extraordinary occurrence” he said.
About 6 units at both Lethabo and Matimba coal-fired power stations are out. This equates to about 2,600 Megawatts (MW) loss of electricity.
Dr Kgosientsho Ramokgopa, the Minister of Electricity and Energy, said although this is a perfect storm, affecting two of the best power stations, the crux is to protect the integrity of the grid, and reserves.
He also said the trend line in the roadmap developed, points to a positive trendline.
“We are within touching distance of ending loadshedding and we are disappointed with the setback.”
Speaking about the setback, Bheki Nxumalo, head of Generation at Eskom, said the situation was aggravated by delayed units coming back from maintenance.
He also said boiler tubes failed in some units.
He also said maintenance is planned for Kandall and Kriel Power stations.
