What the heck is a Virtual Power Station?

Eskom so desperate they're counting imaginary MWs now?

That would be the mines, smelters etc that get load shedding way before the general public do

Demand shifts during load shedding, it seems the higher the load the more the shift.
Think about it, you're going to go off at say 8pm, so you start doing everything you'd do from 8, earlier cooking washing and such. Than on top of that you've got the guys who have just come off shedding at 6 now playing catchup, some of them since four hours earlier instead of 2.
This is why it's so high as they've just shifted demand, all the geysers coming back on after 2 or 4 hours, people cooking, cleaning whatever.

Definitely a double edged sword for Eskom

I've always wondered when we'll see average demand starting to rise due to all the batteries etc starting to charge up after continuous load shedding

I question how much loadshedding really helps due to this, especially as more people have battery backups

There's also a cold front.

Basically seeing it now

This is the problem, a lot of the time it's pointless as it's just shifting around it's not even consistent. If I look at say the last 2 Septembers the demand was around 28 to 30GW, this year higher than 30? What's that all about? Also people who moan their bills are the same or higher even with load shedding, it's like yeah, you're charging everything when the power comes back, putting the kettle on and and and.

There is? It's been a little cloudy the last couple of days but not cold.

Oh dear those numbers don't look good at all...

I still wonder what they'd actually look like without load shedding, as this is just demand shift. More people trying to cook supper sooner or after they have been hit with the shed.

Didn't covid wreck the economy?

It's been **** cold and raining in durban mon-wed. Today the sun is out.

Not last year September most things had ramped back up, though strangely enough it was actually lower than the previous September.

Check is pinned tweet, it explains it.

Thanks went and checked. Makes sense I suppose. They're clawing back MWs from smelters.

Yeah but your guys cold is like 21 degrees and it rains almost every afternoon

 

[Yuu]

Announcement incoming ? We supposed to shed from 11:00am to 13:30pm but went off 10mins . Something is happening ‍.

Edit: power went off again ‍ . Maybe faulty Eyebox

Yup. Though in reality a VPS is a system that fires up different power sources, turns off ripple relays, reduces power to certain big industries, ramps up power at OCTGS.
So basically it's a system to manage different power sources and means to ensure grid stability, in Eskoms case it's basically another form of ILS.

It was 15 bru, dropped to 12 at night and mornings. Had many blankets and heater on.

Doubt it, you're just lucky.

What a nice warm evening like that, blankets I don't even pull a blanket out unless it's 6
