I'm sure that battery storage is having an effect.

During power-off periods, people are still consuming the same or similar number of kwh from their batteries as they would have from the grid.
When their power comes back, they need to pull those kwhs back from the grid to charge their batteries. Their net energy consumption has not been affected by the loadshedding, but their peak consumption has been time-shifted (to after the load shedding slot) and probably also increased (I drained batteries at 700w and charged them at 4KW...)

So my 700w steady state consumption has changed to zero for the load shedding period, then multiplied by 6 for the first hour or two post loadshedding.
You can't tell me that this, multiplied by how many thousands of battery/inverter systems are out there, has no effect on peaks.

Not forgetting that after 4 hours things like geysers kick in to warm back up, fridges kick in. Also around 6pm people start cooking. But now there is a bit of a problem, not everyone cooks at 6pm, but the people who were off from 2 to 6pm now do, so do the ones that were from 4 to 6, so do the ones who go off at 8, plus at lower stages you've only got less areas coming back at the same time, stage one would be 10, stage 6 is 60 areas all coming back at the same time.

Its also why everyones accounts are staying the same or increasing, no one has gone really from R1500 a month to R500 because they never have power...

Yup and even those silly little inverters will use 10 to 20% more then the power you actually draw from them. Plus it's all the alarm batteries, gate batteries.

No point trying to explain this to someone who fails are reading comprehension and basic understanding of things. You guys are going round in circles.

Eskom belongs to the taxpayer. We should be able to see what is going on and able to check on it's progress. It should be public knowledge what our power stations are doing (or not doing).

Why don't you drive to your nearest power station and demand to be let into the control and examine their production and maintenance information because they're a publicly funded company? Do you, for example, know what shareholders of publicly listed companies can't do the same?

Hahaha :p in general where there has been less pollution over certain areas it's showing more smog.

Come to our area in the middle of winter, where the vagrants that take up residence on the Braamfontein Spruit, start burning anything and everything to stay warm :rolleyes: the sweet smell of plastic and tyres in the air...

That is very inefficient, and why would I want to go to a useless power station anyway? They wouldn't let me in anyway because I could be a danger. Just let me log into the screen the national control room centre looks at.

Didn't you move though?

Again that is not true
There was practically no LS over Easter weekend, it spiked by 3000 straight after
That is production playing catch up of 4 days of losses
The following weekend Tutuka and Koeberg were offline
It is also why eskom and news were throwing around load curtailing terminology
Load curtailing is only directed at the manufacturing and agriculture sector not households
Load shedding reduces demand, it is what it is designed to do

I'm 100% behind you here. What's needed is public pressure to force govt. (it IS them in charge, completely as we know) to ensure Eskom becomes sufficiently transparent, all the time. How is debatable, when is now

I have my moments. But that isn't reading comprehension - that's me being lazy to proof read what I type. Typos happen...

Also, the post was not aimed at you.
