Increased solar and wind power making grid stability management trickier

The answer is right there. Batteries.

Move with the times Eskom.

Yes, or use the power to pump the water back up to the high dam at drakensberg when demand is low, and use the hydroelectric power when demand is higher.. And.. Build a few more water batteries like this.. Why don't ya..
Or
Stop complaining about everything and do your job.
I could go on..

Yeah cause building dams is easy, especially for pumped water.
They already do use the solar where they can to pump water if necessary.

You have all that power at your finger tips :) have you got nothing that can run during the day to use the sun while it's up?

Pretty much everything is always on, Looking at getting a aircon, maybe 12K btu....

I personally do not think the previous government found it easy either, but It would be a reality if they started with the extra new hydro and other powerstations and dams many years ago..
And so they should, but much more important to create new ones to cater to demand.. Nothing dramatic or new has been done in 30 years.
Who would've thought I was just idly dreaming of possibilities and then verbalizing it all for a friend.

Something isn't right with those numbers then. I've only got 4.3 installed solar and today with some on and off clouds I've already pulled more than your average.

Do they? Or could it just be because they have backup from other areas?

Well, yes, competent employees would arrange backup too, all in a days work. An unremarkable part of the job.

I dont use alot of power. my geyser averages 1.5Kw per day. fridge and freezer uses 200W max

Weird it's not showing on the results. Cause you should be easily drawing 21kWh a day with your array

Definitely more

I have a 3.65kwp array and this time of year i do 20kwh ish on sunny day

With 100% utilisation
That is the hard part with bigger arrays having enough load to use it

More batteries solves it at a price though

It does indeed seem so, we need to get you a bitcoin miner or something

That they do
 
So on the one hand they want to say solar isn't solving the loadshedding problem

And on the other hand want to say the solar dip is adding to their headaches of maintaining the stability

As jou oggend en aand praatjies nie op match nie :)

It becomes a bigger problem if grid feed is incentivised properly

Which they aren't
Doing , they are however incentivising the dip with exorbitant prices

They are making their own bed

Do you use any eskom power or is your load just this low?

Don't expand the solar for the EV

Just use what you have first
You may be surprised how much is going to waste

With 100% utilisation you should be able to generate

36kwh (sunny day naturally) a day depending on your daily km driven you may find current setup can handle the daily top up already

Yea either get the car or more batteries

Then he can carry sunny days over to rainy days

I have a 7.2kwh battery and 3.65kwh and it takes effort to use what i generate

I reckon the ideal battery size for my current load and array size is 15kwh minimum

So with bigger arrays more is needed or more load

Otherwise lots of wasted capacity

Nice for rainy weather though
