First time Im sitting in the dark again in a long time.
Seems the maid was really hard on the electricity today and the grid disappeared around 15:45 and hasn't been seen since.

Batteries went flat?

If demand shot up to 37GW - as he says; we'd be in for a world of hurt, for sure. 37-24=13 (stage 7(8))

mybroadband.co.za

Don't see 38 there from 2007 to 2022

I think we’ll probably peak at 34GW this year.

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

This shows how resources were used to build-up the demand over the past 7 days, and it includes both generation and demand side resources that Eskom has contracts with.

System hourly demand and available capacity - Eskom Data Portal

Hourly demand is compared against available capacity, to indicate the amount of surplus/shortfall there was. Available capacity must be matched with the total RSA contracted demand.

I never know what I am looking at here - is it good or bad?

I only have the one 5kwh so it takes a bit of a beating.

Still no power this morning so waiting for the sun...

I must admit, I too can't understand these graphs. Luckily for people like me these is ESP

It's bad, very very bad.

If the first graph has any MLR (loadshitting gold colour) then its bad. It shows how much generation is missing to make up the difference. Seeing OCGT's (red and beige) is also bad because that is Eskom digging its hole deeper as it costs R4/unit but they sell it for R1.50 and normally is only meant for a few hours a day during peaks, hence the name peakers. You also see Koeberg going down with the missing yellow colour.

The second graph shows how demand is exceeding supply, hence the loadshitting.

Anyway, it's not important if you understand it or not, I'm just doing it for the historians for later when they're sifting through the ashes.

The graphs look so weird without the giant yellow block isolating the coal

How about when coal was more than 20GW last Spring:

 

[R13...]

Highest was 37GW in 2011

And that decline in demand is the sound of de-industrialization and economic decimation in progress. Good time.

Actually it's a number of things

 

[ToxicBunny]

Actually it's a number of things

Yeah, I would tend towards thinking the biggest driver towards a reduction in overall demand in the last 20 years has been the general power efficiency of industrial equipment.

Power is finally back...

But placed the order for another battery I'm sure I'll need soon.

What industrial equipment?

 

[wingnut771]

I would say mainly a decline, especially when you factor in population growth.

 

[Parched]

I agree there are a lot of factors at play when it come to electricity demand, but given what's happened with increased electricity costs and increasing unreliability over the years (since the days when this was a great location for energy intensive businesses to be set up) it's perhaps not surprising what has happened with demand. I guess the next decade will see some residents and businesses reduce their demand from Eskom as they switch to generating more of their own power, but how far that is offset by demand from the growing population will be interesting to see.

when are we going to focus on skills instead of baseless platitudes. btw this solar setup is worth every cent

If only the same amount of effort was put into something productive, we would be leading the world here...
