Come try live in dbn without aircon, also keep the pool clean without running the pump.
Can't comment on how things are now but when I was a kid I was at my cousin's place every weekend and we managed without aircons in Isipingo during summer. This was over 20 years ago though, and yay, climate change...

Sorry but a pool really is a first world problem.

I also grew up in dbn north without aircon, I guess as kids we don't feel the heat. I was just pointing out how peoples' power bill can be more than your bear minimum.

Yeah I am not "power conscious" really, but I also do try keep things reasonable and I struggle to get the power bill down below R2500 per month in Durban... this is for a 4 adult household...

The only good thing De rayter has done so far is reduce Eskoms debt. Going into a considerable amount of new debt for unreliable grren tech is stupid.
Rietrot, you clearly do not understand how the REIPPP works. Eskom will not spend one cent of capital or debt interest. Wake up.

And in other news. The whole of Lesotho was glowing while SA was a black hole in space. One of the least productive countries just like Zim getting electricity from the SA tax payer.

Ill upload it myself onto YouTube today. Although it is obviously coal export, seeing thousands of coal trucks leaving SA does raise some important questions about Mantashe, his clash with de Ruyter, wet coal excuses and just how much of our own precious energy we export.
Are you sure its coal and not chrome from Steelpoort Valley?

This is what I found when I tried to find a link of what you were saying:

This was 2020 though.

Anyway, most of our coal is exported. I always thought it was by railway though.

No, I have faith that the EV's of the future will act as the "storage" as a car is parked 90% of its life. EV owners can buy and sell power.
Again, just swallowing media wishful thinking - who push their "reimagined dream world", which is free from constraints or physics or reality, but full of emotions. Maybe it will work in Zuckerberg's new Metaverse - but not in actual reality!

Some figures on EV's

I think the BMW i3 has a 42kWh battery and a range of about 200-300k's? (Just quoting from memory so that might be wrong).

Now I consume about 11kWh a day a home (I run quite an efficient home).

So to fully charge that car would increase my consumption up to 53kWh per day which is an increase of 381%.

So if the majority of home owners did that, the suburb supply infrastructure would need to be increased by about 3-4 fold. (Yes you can argue that not everyone will need to fully charge - but the trend stays the same).

In case you don't know, that's not generally technically feasible, in fact most councils are trying to reduce load on their existing infrastructure, because their networks are overloaded by unplanned high density development.

Not to mention, when is the time most EV owners would plug their vehicles in to charge - when they get home at night?

That's precisely the time that maximum load is experienced on the network, when power is in extremely short supply. And now every home has tripled their demand right at that point!

Even the most basic thinking around EV's just results in all the issues getting generally worse, not better.

As I said, if you want to "save the earth" revert back to the 1800's and adopt that life style. Toss all your appliances and ride a horse. If you are not willing to do that, then stop pretending that you are somehow solving the problem using the "thinking" that the media is giving you. It's all just a scam to set up new markets with potential government/regulatory enforced cashflow streams to global corporations who are lining up to benefit.

I have nothing against electric vehicles - they look like an interesting new technology, but they are not going to replace internal combustion engines any time soon, especially in this country. Wouldn't mind one myself as a city run-around. But they are not going to "save the planet".

Nor are they going to behave like some distributed storage device, they are going place a massive load on our already collapsing electricity supply - nothing else.

Introduce peak and off peak rates.

People will set their cars to charge during off peak.

A lot of people will have solar and WFH.

Their cars will be fully charged and when it gets rainy can feed a certain amount into the grid. This will save Eskom from running expensive OCTGs.

We can invest in geothermal power stations to replace coal as baseload.

By then the ANC will be out and we will have competent officials running things.

You know you can unlike a post...

Anyways a lot of what you posted is outdated. Coal and nuclear are no longer reliable cheap options. Renewables can be provisioned by a factor where the concerns no longer matter. But I digress, we won't be rid of coal anyway for the next 30 years in which time a lot would have changed.
What exactly does that even mean?

" Renewables can be provisioned by a factor where the concerns no longer matter."

Um when the wind stops blowing, and the sun stops shining, how do you "provisioned by a factor where the concerns no longer matter". Or is that just a new phrase which means "load shedding"?

Either you have a balance between consumption and generation on the network at every second, or you don't.

Playing with words, or saying something is "outdated", or in fact saying what ever you like, doesn't balance demand and supply.

You either have a source of power at that point, or you don't.

Hope is not a reliable strategy.

Everything you say is wishful thinking.

You need to face reality. The numbers are big, hoping that something will just materialise to justify something which right now does not look like it can work - is just an abdication of objectivity.

That's just the thing the anti-renewables keep drumming on. We don't have days where the wind doesn't blow and the sun doesn't shine. It's always one of the two at least and even if we did there are other options as well. We keep hearing about the EAF of solar and wind but the cost of renewables (most is actually initial) is so low that you can provision ten times what you need.

This will not work. Because of selfish people.

You won't use full charge over 24 hour period.
I have 2.4kwh of solar panels and they generate easy 15 units over 24 hour period.

How often do you fill your car with dead dinosaur liquid?

Daily? Or maybe once every 2 weeks?

Why would it be different for a regular EV?

Average commute in SA is 40km day.
15-20KWhr/100KM. Lets say 20., so a whole 8KW a day extra.

8KW over night is roughly 1KW over 8hrs. We have more than enough grid capacity for that.
I actually did the calcs in another post if you don't believe me.

That's precisely the time that maximum load is experienced on the network, when power is in extremely short supply. And now every home has tripled their demand right at that point!

Alternately, the cars charger could be aware of Time of Day charges, and charge at the cheapest time rate - which would be overnight, when we have plenty of excess capacity.
i.e. you come home, plug in, it starts charging at midnight as the electricity is cheaper then*.

Or just start charging after 12pm.

*We don't have time of date fee's yet, but they are coming.

If you absolutely needed a charge at 7pm, you can, but time of date fee's (its peak rate), will encourage you not to.

Voila, non issue solved.
