Well everyone's inverters and **** having to charge all the time will use quite a bit extra

I have not charged my batteries from the grid in a while - maybe early last year. But if we go beyond stage 6 - I might have to charge them from grid.

I got solar and yesterday had 12 to 4pm panels charged that fine but then had 8 to 12.30 again and then after 12 it pulled from the grid...

I was more referring to people with just inverters not panels

What I normally do for stages 4 upwards is set it to charge till about 8pm from Eskom, so when the sun goes down pull from Eskom till 8, if we have 6 to 8, pull from 8 till 10 :), actually works out that I pull less from Eskom doing that then allowing it to get to 20% and pull from Eskom
 

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.

We haven't had load shedding once this week since the pylons fell. But Tshwane send a notice that it will start again this morning. So will see what happens at 10.
 
We are basically up to 5 hour blocks. Restoration always takes an extra hour.

Curtailment means they "ask" heavy users to "cut down". In this context - how is stage 4 defined, what happens if those users don't comply and how many GW does "cut down" translate to?

As far as I understand, "load curtailment" is voluntary. The industrial user agrees to reduce their load for a set period of time and in return gets compensated by Eskom for the loss of revenue.

So we renting a system and i don't believe it has these capabilities, we have 3 battery settings to play around with but can't do stuff like this unless we use the battery settings to bushfix vibes it...

We running the mid tier option generally during the day which uses like next to no Eskom and then the conservative option during the evening to ensure our battery stays as high as possible.

It's "voluntary" in the sense that you either agree to be curtailed or get load shed without notice.
He said when Eskom declares stage 4 load-shedding, it can request any major industrial consumer, such as mines and smelters, to curtail up to 20% of load.

The % depends on your stage of load curtailment.

The big industrial users usually have some pretty complex and watertight contracts with Eskom. So basically, if Eskom is forced to cut their power they get compensated.

Other users such as smelters cannot be shed without notice as that could mean writing off most of the plant.
