Eskom's plan to build small nuclear reactors

You plug it into the Renewable power grid. Seriously, smelters don't use some kind of different kind of electricity than other users. An electron is an electron.

And when the wind don't blow and the sun don't shine? They fire up the gas/diesel

Really so they are building more coal for?

China responsible for 95% of new coal power construction in 2023, report says - Carbon Brief

China accounted for 95% of the world’s new coal power construction activity in 2023, according to the Global Energy Monitor.

Cause they like the smoke it makes?

I lot of people are wondering why they are building more - because the capacity factors on their coal plants are dropping to something like 50%, and the plants are starting to lose money.

People speculate it might have to do with local government incentives.

But it is a mystery, I will grant you that.

Or... They cannot run their production, those light shows at night with renewables... It's still not an ideal solution

Well. Batteries and storage. And luckily wind and solar is not synced. And gas plants to bridge the gap is okay. I mean we use gas today to try and bring demand and supply in balance (because coal is terrible at following demand).

I mean I am not arguing that there are no engineering challenges. But that is just it - engineering challenges.

Hell our grid was originally designed around engineering challenges of the times.The grid was modelled around "Baseload" not because it is the best way to model consumption, but because coal plants cannot easily adjust to demand and had to be run at fixed capacity.

You can also add an inefficient grid to that which is essential for renewables. They don't share enough power between their provinces.

Yup inefficient grids are not a good thing for renewables

Warnings Australia's energy transition 'out of control' as NSW market quietly melts down

It passed largely unnoticed, but a NSW energy market meltdown has sparked warnings the energy transition is veering off the road.

Why post about stuff that has got nothing to do with renewables?

Among the blows were a number of planned and unplanned outages at coal plants in NSW.

and
At the same time, Mr McArdle said there were disruptions to high-voltage power lines linking NSW to Queensland and Victoria.

So you no read further

"Mr Dimery, speaking at an oil and gas industry conference in Perth this week, said the intervention by AEMO was a portent of the disruptions to come if Australia failed to properly handle the switch away from fossil fuels and towards renewable energy."
"He said the energy system was getting more fragile as the addition of new clean sources of power failed to keep pace with the retirement of coal-fired generation."
"Mr Dimery said adding in ever more intermittent renewable energy without the capacity to back it up for days at a time was fraught."
"While batteries were extremely well suited to tasks lasting up to about four hours, he said other options were desperately needed for longer-duration requirements."

Yes, they have their timing a bit off that's all. There's no reason why a place like Australia with no big industry can't pull it off. Their demand is tiny compared to us.

Also, this "melt down" was just over 7 days because of perfect storm of factors. Did their power go off? Would this have happened if there was a million EVs with V2G plugged into the grid?

China also has loadshitting by the way. In Australia, the lights stay on when they loadshed.
