“There will be no load shedding today [Monday]. We managed to restore coal supplies to two of the six units at the [Majuba] power station. This means that one third of the power station’s normal capacity is back in service,” said spokesman Andrew Etzinger.
“As a result Eskom is not needing to implement load shedding during the day. However, the power system remains under pressure and consumers are urged to use electricity sparingly for the remainder of the week.”
A coal storage silo at the Majuba power station in Mpumalanga cracked on Saturday and later collapsed. Etzinger said as a result coal conveyor systems were damaged.
On Sunday, alternative measures were put in place to deliver the coal needed.
“For units one and two, we had to bring in coal through an alternative delivery mechanism involving the trucking of coal,” he said.
“Then the coals were placed on mobile conveyors using front-end loaders, and the current rate 1200 tonnes of coal per hour were being brought in.”
Eskom was working on a similar solution for delivering coal to units five and six.
FIND YOUR LOAD SHEDDING SCHEDULES:
The Citizen has compiled a list of load shedding schedules from across different municipalities. Due to the fragmented nature of the information available, not all schedules may be accurate or up to date. If your schedule does not appear here or is not up to date, let us know.
Should you be powered directly by Eskom visit the Eskom load shedding site to find out when you’ll be out. Type in your suburb/area in the search box to easily locate your area, i.e. Pimville or the Midvaal municipality.
Eskom has also collated a list for municipal customers which can be accessed here.
He said units three and four were not affected.
The operation involved excess manpower and cost but Etzinger could not immediately provide figures.
The following slides from the Eskom presentation show how the system works and where the collapse happened:
The coal is fed by a double conveyor belt from the stockyard to a central silo. The central silo feeds coal into units 3 and 4 and to two other silos on either side of it that respectively feed units 1 and 2 and 5 and 6. The green arrows indicate the coal feed.
The central silo, market with a red circle, collapsed which disrupted the whole supply system.
The blue blocks indicate the alternative coal feed Eskom hopes to implement utilising trucks. Unit three can be fed from unit two, although that will only allow it to operate at 75% capacity. Unit 4 will be out of service for the time being. Eskom will use the opportunity to do the planned maintenance on it that was scheduled for the end of November.
