There is a low probability of rotational load shedding during the day today as a result of power station units being returned to the system.
However, the probability of rotational load shedding increases for the evening peak period from 5pm to 9pm due to the normal expected increase in demand, Eskom said.
Should rotational load shedding be implemented today it would be for a period up to four hours. Eskom will advise if rotational load shedding will be conducted in either stage 1, stage 2, stage 3 or stage 4, dependent on the capacity shortage.
Stage one requires 1000MW to be rotationally loadshedded nationwide, stage 2 requires 2000 MW, stage 3, 3000 MW and stage 4 calls for up to 4000 MW.
While safety of employees remains our first priority, recovery teams at our power stations continue to work hard to stabilise the power system and to return our generation plant as quick as possible, Eskom said on Monday morning.
Eskom’s prognosis is that the power system will take up to 10 days to recover from the effects of the recent industrial action, once all staff eventually return to work today (Monday).
The estimated ten-day prognosis for full restoration is due to the effects of the industrial action which interrupted continuous processes at the power plants. These processes have now to be cleared out and restarted which would take additional time.
• Coal management and transportation: the inability to transport coal from stock yards to coal bunkers due to the absence of operating staff. In addition, the already low coal stockpiles at some stations were exacerbated by road closures as coal delivery had to be suspended.
• Significant increase in plant outages and a bottleneck in routine maintenance due to the lack of resources to optimally operate the plant; such as ash clearing and mechanical failures that occurred during the period.
• In addition, Eskom is currently managing diesel levels at its peaking plants at 50% to ensure that sufficient diesel generation is available for emergencies.
• Increase in production and full stability can only increase and be achieved with the return of employees. Eskom will continue to re-assess the prognosis during the week.
Eskom encourages residents and businesses to use electricity sparingly to ease the demand. Switch off geysers during the day, especially during peak periods (7am to 10am and 6pm to 9pm), as well as all non-essential lighting and electricity appliances.
