Eskom says probability of daytime load shedding is low

But the utility says the probability of loadshedding is higher for the evening peak period due to increased demand.

Eskom says there is a low probability of rotational load shedding during the day as a result of power station units being returned to the system after last week’s wage strike, but the probability was higher for the evening peak period because of increased demand.

Eskom said at the weekend the system remained constrained and that it would take up to 10 days to recover from the effects of the strike, which was characterised by sabotage on its stations.

“Should rotational load shedding be implemented today it would be for a period up to four hours,” it said on Monday, adding it would advise if rotational load shedding would be conducted in either stage 1, stage 2, stage 3 or stage 4, dependent on the capacity shortage.

Stage one requires a load of 1 000MW to be rotationally shed nationwide,  stage 2 requires 2 000MW, stage 3 requires 3 000MW and stage 4 calls for up to 4 000MW to be rotationally hed nationally. Load shedding is conducted as a measure of last resort to protect the power system from a total collapse or blackout.

“While the 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 quickly as possible,” Eskom said.

“Eskom’s prognosis is that the power system will take up to about 10 days to recover from the effects of the recent industrial action, once all staff eventually return to work today.”

The government and unions have agreed to resume negotiations that had stalled over Eskom’s decision to not award salary increases due to financial constraints. At the weekend, the National Union of Metalworkers of South Africa said the zero-percent proposal by Eskom was now “off the table”.

Labour unions are demanding a 15 percent increase for workers at Eskom, saying their members should not suffer for a financial crisis brought on by corruption and mismanagement by senior executives who have since been fired.

It said the strike had interrupted continuous processes at power plants, including coal management and transportation, which would now have to be cleared out and restarted, taking additional time.
