As South Africa faces an ongoing energy disaster, issues come up over the opportunity of stage 16 load-shedding, which might entail 24 hours with out electrical energy for households. Whereas Eskom and consultants within the area emphasise that such excessive measures are unlikely until a significant disaster happens, a brand new nationwide requirements doc proposes load-shedding schedules as much as stage 16. The present system solely goes as much as stage 8, leaving municipalities unprepared. This precautionary measure goals to make sure an orderly implementation of upper rotational energy cuts if needed.
What Stage 16 load-shedding would appear like
By Myles Illidge
Stage 16 load-shedding primarily means 24 hours per day with out energy for households, though South Africa continues to be a great distance from implementing such excessive ranges of energy cuts.
College of Johannesburg physics professor Hartmut Winkler informed MyBroadband he believes one thing must go drastically mistaken within the close to future for stage 16 load-shedding to turn out to be a actuality.
On 11 Might 2023, Eskom confirmed that a brand new nationwide requirements doc proposed load-shedding schedules as much as stage 16.
The present load-shedding schedules solely go as much as stage 8, which means a push to larger phases would depart municipalities and distributors at midnight about the way to implement larger ranges.
Eskom’s system operator is answerable for the steadiness of South Africa’s nationwide energy grid and will order larger energy cuts if needed.

Nonetheless, a schedule as much as stage 16 would make sure that larger ranges of rotational load-shedding are applied in an orderly trend in the event that they turn out to be needed.
MyBroadband requested Winkler what a stage 16 load-shedding schedule may appear like. He mentioned he expects Eskom to vary the present rotational energy minimize sample to make smaller increments.
“Stage 8 means 12 hours with out energy, so if the brand new schedule follows the identical sample as the present one, then stage 16 would imply 24 hours with out energy,” mentioned Winkler.
“They might, nonetheless, change the present sample in a way that the increments are smaller.”
We additionally requested Eskom for suggestions, and it confirmed that households ought to anticipate no energy if load-shedding reaches stage 16. Nonetheless, it highlighted the truth that the proposed schedule is solely precautionary.
“On a 2-hour load-shedding schedule, at stage 16, you’d anticipate to be off for 32 hours in a 32-hour interval,” it mentioned.
“The event of schedules past stage 8 is merely a precaution to make sure that these exist in the event that they had been ever to be required.”
“The present scenario is that, ought to the necessity come up for load-shedding past stage 8, the System Operator would instruct every province to scale back by a further particular [megawatt] quantity,” Eskom added.

Nonetheless, it famous that this wouldn’t be carried out in a scheduled, systematic method and wouldn’t be recognized to the general public, therefore the necessity for the schedules.
Winkler identified that load-shedding would solely attain stage 16 — or the shedding of 16,000MW — if one thing had been to go drastically mistaken.
“Stage 8 additionally means shedding 8,000MW of energy, and in response to that scheme, stage 16 means demand exceeds provide by 16,000MW,” mentioned Winkler.
“South Africa, nonetheless, has way over 16,000MW accessible, so stage 16 implies we’re nonetheless very removed from having no energy in any respect.”
“The remaining energy goes to industrial customers with particular contracts with Eskom (e.g. aluminium smelters), who prior to now have escaped many of the energy cuts,” he added.
Winkler additionally defined that these customers could be required to hold a number of the load-shedding burden earlier than larger phases are required.

Nonetheless, he mentioned it was unclear how the burden could be shared with out seeing any draft schedule.
Eskom mentioned the brand new nationwide requirements doc additionally proposes extra phases of load curtailment, though there are some sensible limitations on industrial vegetation.
Load-curtailment is a mechanism Eskom makes use of to scale back demand from energy-intensive customers in South Africa, like mines and smelters.
In return for his or her participation, these prospects are compensated financially by Eskom and might be exempted from nationwide stage 1 and stage 2 load-shedding.
Load-curtailment schedules beforehand solely went as excessive as stage 4.
