Eskom Data: September 2025

Eskom data - September 2025

Another dip in unplanned outages takes us close to 2020 levels!

I think the best EAF in september since 2018, top of the chart for my curve graphs as they don't go back that far.

We're hardly using the OCGT backup generators any more, with very low average and max use (relatively speaking).

Very low imports too. Is everything down.

Massive demand drop.

I need to go double check that I'm not missing data that causing this, because it looks sus.

also weird, IOS (interruption of supply, a mechanism that lets Eskom cut off business users) went up a bit compared to last month.

but ILS (interruptible load shed) went down 🤔

I'm not sure I totally understand each of these, but maybe it's because iOS includes transmission network faults.

The transmission network seems to be the bottleneck now instead of generation which everyone has been focusing on, as many people predicted?

As always all data and graphs from unofficialeskom.com. Feel free to let me know any questions or answers.
