Stage 1 load-shedding to move to Stage 2
Eskom has announced Stage 1 load-shedding will move to Stage 2 from 9:00am on Friday morning.
The power utility said the system remains vulnerable and while they have returned units to the system, they lost additional generating units on Thursday necessitating load-shedding on Friday.
On Wednesday, President Cyril Ramaphosa said sabotage at the power utility is partly to blame for load-shedding.
Ramaphosa said decisive action needs to be taken against the sabotage at Eskom.
Eskom has asked that customers reduce their use of electricity as a decrease in collective demand would ease the load on the system.
Eskom Load Shedding Today Full Details (Time, Location)Below is a detailed list and explanation of the load shedding schedules made available.
WHAT DOES STAGE 2 and 4 LOAD SHEDDING MEAN?
You will be scheduled for load shedding 12 times over a 4-day period for two hours at a time, or 12 times over an 8-day period for four hours at a time.
If more load needs to be shed than has been scheduled in Stages 1, 2, 3 and 4 then National Control will instruct additional, unscheduled load shedding. This means you may be shed outside of your scheduled times.
To prevent a nationwide blackout, Eskom needs to maintain the national power grid at the international standard of 50Hz, and when the grid is under pressure with normal measures implemented, Eskom must reduce demand, as agreed with the National Energy Regulator (Nersa).
Eskom then implements a process of load reduction which has two components:
Load Curtailment – The utility can instruct industrial clients to reduce electricity consumption when it is urgent to balance the system. This can reduce the load by up to 20%, significantly easing capacity on the grid but it can take up to two hours to implement.
Load Shedding – Load curtailment fails to ease the demand on the system, or there is not enough time to notify industrial clients of the need to reduce their consumption, Eskom implements load shedding to prevent an imbalance and subsequent blackout.
Load-shedding will be used under emergency conditions for limited periods.
Four schedules have been developed based on the possibility of risk and to ensure that load-shedding is applied in a fair and equitable manner:
- Stage 1 allows for up to 1000 MW of the national load to be shed.
- Stage 2 allows for up to 2000 MW of the national load to be shed.
- Stage 3 allows for up to 3000 MW of the national load to be shed.
- Stage 4 allows for up to 4000 MW of the national load to be shed.
Load-shedding will be implemented in most instances in 2-hour blocks.
- However, in Eskom-supplied Johannesburg areas, blocks are 4 hours long. This is to coincide with City Power’s 4-hour schedule.
Each of the time periods has an additional 30 minutes added to allow for switching of networks in a way that will not damage the power system.
- Most customers (those in 2-hour blocks) may, therefore, be without electricity for up to 2.5 hours at a time, while customers in 4-hour blocks may be without electricity for up to 4.5 hours at a time.
