Eskom achieved its highest daily EAF in 9 years on 20 July 2026

because AI tells me they are using their most reliable and efficient units now which is Medupi and Kusile.

Ah yeah AI. Yes, Eskom does put coal-fired generation units—including those at major stations like Kusile and Medupi—into "cold reserve" during periods of low electricity demand.

Like during winter?

There we go, so they could just be scaling down the load instead of bringing down units.

Yes, we know, because we have roller coaster black bars every day. It takes 72 hours to bring something out of cold reserve and sync to the grid.
I see Eskom can only count to 3 today:

The current darkies seems to be doing a pretty good job. It’s almost like race has nothing to do with it.

They doing fine because the new power stations that took 20 years to build are sort of finished so there's no shortage anymore.

Seeking praise for doing the job you are actually paid to do, pure psychopath behaviour

I've never understood this take. Should Doctors not get praised for performing life saving surgery? Should the police not get thanked if they save someone's life? Do you thank the waitress for bringing your food or do you say nothing because she is just doing her job? Who wants to live in a world like this?

Sure but they don’t praise themselves.

Sounds like you're living in a rather terrible world, cause to all of those they do get thanks. Also do you not tip the waitress? None of your examples is anywhere near remotely the same.
A better example would be the guy who fixes the potholes, or the ones who paint the lines on the side of the road, sure they should be thanked once in awhile, but they are roles people generally don't thank them for. Police, Doctors and even waitresses get plenty of thanks.
 
28GW of demand, with a peak generation capacity of 48GW, does not mean 80%, the biggest difference between the days of LS and now is that all the large industrial users, who had contracted power supply contracts, have pretty much all disappeared, so there is a big chunk of load gone, and thus that roughly 4GW drop in each day, which does make a big difference. you can still see there is a big chunk of OCGT use, which, if there was actual reserve capacity, would not need to be used, as you have enough controllable power, as you can easily use a coal power plant to still provide generation, and act as a load sink, by simply using it as a rotary capacitor, circulating current in power lines. Not the greatest, but doable, and thus you have reserve available for close to immediate despatch.

Reminds me of the late Terry Mackenzie Hoy, who was a pretty decent columnist, and who pulled little punches about competence, telling of a power station where the newly appointed boss saw the one turbine running, and the other shut off, and said he wanted both of them running all the time, so they then ran both, one running leading, one running lagging, to circulate current between them, and incidentally power the area with the difference. Ran till one needed maintenance, which was refused, till both blew up, totally unexpectedly, as to the shock of the appointee, who thought that they would run forever with nothing being done to them.

Did you read what you I was replying to? Of course I tip and I say thank you. They're exactly the same you are just being selective. Telling someone well done for fixing something that was a previous fukup should not be dismissed as them just doing their job. It's called positive reinforcement. We want more of this behavior from our government officials because it is so rare. So when it happens and things get better we need to thank them for doing their job well.
 
lol... All dressed up and nobody wants to take you out...

Because 28GW of demand has nothing to do with the EAF at all.
The EAF is the availability so out of that 48GW they have 38.4GW, that is the 80% figure, from there the demand is 28GW leaving 10GW available. Plus where can you see the big OCGT usage?
