They can only count up to 6... result of 30% being a pass

I'm leaning more towards they've noticed diminishing returns on shedding past 4 so therefore at stage 8 demand would be way higher then it would have been at a lower stage

That would be quite scary. It means we are hitting a wall where they cant save us from a total blackout.

Anybody got the 6pm twitter update for 17 April?
Koeberg running at 599MW.
Cahora Bassa 400MW short.

Station build-up for the last 7 days - Eskom Data Portal

This shows how resources were used to build-up the demand over the past 7 days, and it includes both generation and demand side resources that Eskom has contracts with.

System hourly demand and available capacity - Eskom Data Portal

Hourly demand is compared against available capacity, to indicate the amount of surplus/shortfall there was. Available capacity must be matched with the total RSA contracted demand.

Minileccy's next brilliant engineering recommendation - ban all backup power systems that charge from the grid...

They haven’t posted it.
 
You guys still talking about well-prevented grid collapse... huh?
If you're just joking you're still spreading the fear.

I don’t doubt a grid collapse will happen. But pretty sure we will go to stage 7/8 at some point.

Based on what? Here's how well we're protected from that, something Eskom actually does right;

Photos – Inside Eskom’s control centre during load-shedding

MyBroadband was recently invited to Eskom’s Megawatt Park head office for an overview on how the utility manages the country’s power system to prevent a national blackout.

Some paragraphs from the article (which includes photos);

In order to keep the power system in balance, the generation output is changed every four seconds to match customer demand.

Eskom said that the team managing the broader system that falls under the system operator is much larger than just those within the National Control Centre.

It is made up of around 400 people, which includes engineers, technicians, and computer scientists, working across the sectors of national control, technical operations, the grid code, and demand response.

Most of these employees have either BTech or BSc qualifications, Eskom said.


Aside from the highly skilled workforce that helps monitor the system, Eskom employs Energy Management System software that can perform automatic load-shedding in cases of severe, unforeseen capacity loss.

In order to ensure that changes can be implemented without delay, the utility even has its own dedicated telecommunications network – which it said was bigger than any of the mobile network operators’.

“If the guy in the control room pushes the button to open a breaker in Cape Town, he does so on the telecommunications network,” Eskom said.


Eskom’s general manager for production showed us that he was capable of viewing the exact status of each power plant’s various components – including turbines and extractor fans – directly from his office.

So like for the first time in a long time, we went on 2 hours early? As if we were on stage 4 schedule hmmm

Last time that happened to us, after 10 minutes we went off again :- (
But here's hoping...
