In the media briefing earlier today the Eskom manager mentioned they planned to increase maintenance during the winter months if demand was lower. He mentioned they did this over the long weekend.

That would explain the higher shedding on weekends, except last weekend

2300MW over what we had on Friday and 1010MW from the last update on the 11th. Let's hope that the extra planned is the Kusile stuff cause it does kinda add up

Didn't know you can do maintenance over a long weekend seeing it takes a whole summer season to do it normally.

I guess they would ramp or down on maintenance based on based on demand. Is maintenance supposed to be fixed over a few months?

AFAIK maintenance takes weeks not days. Doesn't it take days just to synchronise a generator to the grid?

The planned maintenance schedule is usually for the entire year, on a week-by-week basis (there is some document floating around where you can see it). But they can adjust that number if, for example, they really need the power.
 
I'm sure maintenance includes small isolated jobs. What I think we can call a fact by now though is there's an endless stream of bullshyte from them too, best to just get on with our lives and take it easy until it actually hits the fan.

*takes a back seat*
 
Lets see if this drop in coal output is just weekend maintenance, biggest ILS usage (LC?) I've seen so far 800MW, not enough wind to save us:

Station build-up for the last 7 days - Eskom Data Portal
