Briefing reporters on Wednesday, 17 June 2015, acting Eskom CEO Brian Molefe said that the power utility will conduct 5,500MW planned maintenance over the winter period. This as the utility has a volatile and aging plant.
The maintenance to be conducted is three times more than the maintenance that has been done in previous winters.
Molefe said that the prospect of a blackout, is non-existent, while adding that the company's build programme is the ticket out of loadshedding.
"There is no prospect of a blackout in South Africa; that is virtually non-existent. We will have stage one, stage two and when things are really bad maybe stage three loadshedding but not a total blackout which represents total system collapse that is out of the question," he said.
Going into the winter season, the parastatal anticipates this winter to be colder than previous winters with this expected to have an impact on the demand for electricity.
"We anticipate to supply 100% of electricity on most days and 96% during peak periods. We will endeavour for 100%," explained Molefe.
Molefe said that even when there is loadshedding, the utility provides power to 96% of the country.
The acting chief executive further added that illegal electricity connections also increase in winter thereby also impacting on the demand for electricity in winter.
While the utility will continue with planned maintenance, it will do so with minimum loadshedding.
"We will continue with maintenance during this winter with minimal or no loadshedding. We will use all resources including IPPs, and open gas turbines to minimise loadshedding," said Molefe, adding that the current coal stock levels were at healthy stock levels.
Molefe said that the company had performed better than expected in the first half of the year.
Open cycle gas turbines has been used extensively to prevent loadshedding and to minimise loadshedding.
He said that Independent Power Producers (IPPs) play a role to the energy grid contributing about 1,872MW when the system is constrained. Medupi's unit six is on track to be commissioned, coming into commercial operation by the end of August. The synchronisation of the second unit will happen in 2017.
The build programme continues to contribute positively to the grid with 100MW coming from the Sere wind farm. "The built programme is our ticket out of loadshedding," he said.
As long as the utility does maintenance under 7GW in winter, it is able to do maintenance without loadshedding.
"We have an immediate solution for Majuba and as a result we are able to enable that all units of 3,800MW run at full load. That has been implemented," said Molefe.
This after one of the three silos, which housed over 10,000 tons of coal each, cracked and later collapsed, impacting coal supplies to six units last year.
Molefe said the investigation into what happened at Majuba has been concluded and will be presented to the Eskom board and shareholder department soon.
The utility has also amended its loadshedding stages. Stage one loadshedding is still at 1,000MW shortage while stage two is still at a 2,000MW shortage while stage three was only put in place where there was a shortage of 4,000MW. "From now on stage three will be declared when there is a shortage of 3,000MW."
When coming to tariff application, Eskom had only applied for 6.8%.
"Our actual application is actually 6.8%. We applied for additional money for diesel to avoid loadshedding, we were only granted about 0.1% or R1. 5bn. R1.5bn for diesel to avoid loadshedding is not enough, R1.5bn is what we use in one month, and in fact it is finished.
"If we do not get the additional R10.9bn for the rest of the year and we switch off the open gas turbines because the regulator is not allowing it, then we will go into loadshedding quicker than we are at the moment," he said.
