Throughout a media briefing, South Africa’s Electrical energy Minister, Kgosientsho Ramokgopa, defined the explanations behind the latest Stage 6 load-shedding applied by Eskom. Ramokgopa emphasised the necessity for elevated deliberate upkeep and addressing unplanned capability losses to make sure system resilience. Eskom’s technology efficiency statistics and the battle to take care of emergency reserves had been additionally mentioned. Whereas Stage 6 load-shedding has triggered concern, Eskom goals to return to decrease phases of load-shedding as it really works to safeguard the grid’s integrity.

There isn’t a shortcut to finish load-shedding — Ramokgopa
By Myles Illidge
Electrical energy minister Kgosientsho Ramokgopa says there is no such thing as a shortcut to ending rotational energy cuts in South Africa.
Throughout a media briefing on Tuesday, 5 September 2023, the minister defined why Eskom needed to implement Stage 6 load-shedding on Monday, 4 September.
He mentioned the facility utility might preserve rotational energy cuts at low ranges in the course of the winter months as a result of it had decreased deliberate upkeep to keep away from larger phases of load-shedding.
“Now that we’ve entered the summer time interval, demand has gone down. So we’re ramping up deliberate upkeep,” mentioned Ramokgopa.
“We’re ramping up deliberate upkeep to make sure that we’re in a position to construct a level of resilience within the system, to make sure that the models are dependable, and to make sure the models give us as many hours of producing capability as attainable.”

He defined {that a} vital consider Eskom’s have to implement Stage 6 load-shedding pertains to unplanned capability loss elements (UCLF) — basically technology unit breakdowns.
“We need to make sure that we preserve the UCLF at sub-15,000MW,” the minister mentioned.
Nevertheless, for the week from 28 August to five September 2023, which excludes weekends, Eskom solely achieved this on three days.
“What has occurred over the previous few days is that the UCLF shot as much as 17,297MW, along with ramped-up deliberate upkeep,” mentioned Ramokgopa.
“The Stage 6 load-shedding that we’re experiencing now’s largely on account of, firstly, us [Eskom] ramping up deliberate upkeep, and the problems of UCLF.”
“I actually need to conclude to say that there won’t be a shortcut to the ending of load-shedding,” the minister added.
Eskom’s technology efficiency statistics, together with out there capability, deliberate outages, UCLF, and forecasted demand, for the interval from 28 August to five September, are summarised within the desk under.
Nevertheless, Ramokgopa’s figures present a shortfall of roughly 3,200MW from the forecasted night peak — equal to Stage 4 load-shedding, not Stage 6.
Bheki Nxumalo, group govt for technology at Eskom, clarified that the necessity for Stage 6 load-shedding associated to the facility utility not having sufficient emergency reserves.
“Stage 6 is one thing that we’re, in any respect prices, working to keep away from due to its impression,” mentioned Nxumalo.
“On a day if you lose extra [generation capacity], you then begin to use extra of the reserves, which created an issue.”
He defined that out there pumped storage reserves began to deplete on 29 August, which was compounded when Eskom misplaced producing models from 2 September.
“A few of these models haven’t returned. We’re nonetheless busy with them,” mentioned Nxumalo.
“In order that led to our reserves being depleted, and we didn’t have sufficient time to get better them.”
Nxumalo added that Eskom can’t let its emergency reserves go under a sure stage, which the System Operator controls to guard the grid’s integrity.
“In the direction of the tip of the week, I’m assured that we can return to decrease phases of load-shedding,” he added.
