How to prepare for a total Eskom blackout

Yes, it's hard to imagine a scenario where Eskom wouldn't be able to get at least some limited supply going. Often cited is that the stations require power from other stations to get going, and if everything has tripped there is no way to get anything going again, but we have nuclear, solar and cross border sources of power that could surely be used for this.
100%...

I would honestly think at full blackout state, we'd be without power for 3 days maybe (if you're in a major centre)... if you live in the middle of fsck arse nowhere, then longer...

TIA... the second its heard 'all power is down', all the cables are looted and subs raided and stripped... there will be nothing left to turn it back on for
Ahhh yes, well that is a different issue now isn't it...

Don't think they'd be able to get to all the major infrastructure in time to steal it all though... thats an absolute shyteload of copper to get.

A total blackout will be akin to civil war

Robbie van Heerden, a senior energy specialist at the CSIR and Eskom’s former general manager of the national electricity system operator, previously said a blackout would be a disaster “akin to civil war breaking out”.

He explained that during a blackout, darkness, no or minimal telecoms, water schemes running dry, social unrest, and looting would occur.

Western Cape Premier Helen Zille explained in 2015 that while generators will be able to provide some reprieve, their fuel will run out.

“Cellphone companies can no longer transmit signals. Radio transmitters also die. So do ATMs,” said Zille.

Sewage pump stations would overflow, and hospitals and clinics would also stop functioning, she added.

“The criminal justice system, including courts and prisons, would grind to a standstill. Public transport would come to a halt. Shops would close.”

“Life as we know it, in a modern economy, cannot function without electricity,” she said.
I think this is very alarmist. While it wouldn't be a great situation, I really can't envisage a scenario where at least some limited generation wouldn't be running within a reasonable time frame.

What value would the copper have if there's nothing to use it for?

How would they steal electricity with illegal connections?

Black start

Besides leaving the country without power, a national blackout would leave us in a situation where Eskom would have to restart power plants without electricity – a “black start”.

This could take 2-3 weeks, said Yelland.

Power plants use some of the electricity they generate to operate equipment such as conveyor belts that feed coal into furnaces, so to start them up you need to start with a small generator.

To bootstrap a power plant, a small diesel generator is typically used to start up a larger generator, which in turn is used to start parts of the plant.

“There are procedures and protocols in place to do a black start. This matter has been carefully thought out and procedures put in place.”
If they plan on 2-3 weeks, be realistic and at least triple that considering how inept the people are we are talking about.

3 days without power, heat/cooling, shops, petrol, 7de laan - we would never recover.

Most of the shops and such around me have backup power systems.....

7de laan though, please gawd that production company mustn't have backup power... the world needs to catch a wake up and move on...

LOL, well the economy would probably never recover, but I doubt it would turn into the flat out Walking Dead zombie apocalypse scenario that some of these articles suggest.

Our stolen copper ends up in places like russia etc... its not for local electricity theft, thats small part time coat hanger and tinfoil business

lets face it, a blackstart wont be a pretty sight, if the grid cant cope now with a few generators tripped,
who says it will cope during a blackstart situation, as yes it wont be easy but trying to get everything on wont happen quickly.

civil war, yes, looting, yes, martial law, probably,
and yes even if by some miracle everything comes back, and power is restored at superhuman speeds, the damage would have already been done.
shops would have been looted, anything with copper would have been stripped, no matter how big it is,

so yes a substation is big, but your underestimating what a bunch of impoverished people will do for a buck,
ever seen lord of war, when a bunch of locals completely stripped a huge cargo plane overnight?

same thing will happen here, those places in Soweto that never pay, will have a field day. stripping and damaging equipment.
even worse will be replacing it, I doubt eskom will be able to bounce back from that.

Re this blackstart..

Would they not have to ensure that all users devices, stoves, geysers, heaters etc are off otherwise the few generators that start coming online would just collapse/trip ?

you really have zero clue about reality, in a blackstart situation they isolate the stations, and bring things online in stages. They don't try restart the whole grid all at once (that is impossible).

the rest of your post is just you giving in to fearmongering and then taking your usual "what if" nonsense to the next level.

They isolate the stations from the grid... then bring the grid online in stages so as not to overload the stations that are back online...

A restore from a national blackout is 2 weeks.. not 3 days. I’m pretty sure we are quite close to one and with just a union strike, sabotage or further generational units failing we likely head into such scenario playing out.

She is lying. Ask R13...

A complete restore of power is a 2 week affair... power will be restored in areas almost the same or the next day...
