This would need to be looked at holistically over a course of years, not just two years, especially over the worst case of LS we had, Eskoms sent out number changes drastically over the years depending on a variety of things, if you look at 2014 where sent out was 231 129 and then 2015 it was 226 300, but peak demand was 34 971 and 34 768? You can see just looking at the total sent out doesn't really give the entire picture.

Here is FYI 2025
So 2016 through to 2025, you'll see that the sent out FYI 2024 (Apr 2023 to Mar 2024) was actually 184 576, 191 307 was FYI 2023
If you look at the Total peak demand on integrated power system, MW, you'll see that demand requirements haven't changed that drastically over the years, the peak demand after all the measures has though, especially over 2023 (FYI 2024), almost as if Eskom was removing about 6 stages of load shedding from us. Looking at it FYI 2025 was a massive jump in sent out from FYI 2023, so where did your numbers come from?

Plus the difference between 2023 and 2025 is way higher than 82% (this is actually the difference between 2023 and 2024)

Yes we all like to slander Eskom, but can we do it for the right reasons? Not planning for the future, horrible pricing and and. Articles like these need more research as the info is out there and this one is wrong in so many ways.
As I'm not even sure where this number came from either?
SSEGs expanded further in 2026, exceeding 9,100MW by July, meaning there was nearly 7,000MW more self-generation online than in 2023
As in this article it states solar was at 6.8GW in 2025?
Private rooftop solar power supported more of South Africa’s electricity demand than the country’s sole nuclear power station in the first six months of 2025.

This one was 5.4GW in 2024
Driven by intense load-shedding, South Africa tripled its solar panel imports in 2023, reaching a record-breaking R17.5 billion.

And this one from 2023 saying it was 4.4GW
Private citizens have installed as much solar power in one year as the South African government has during its entire Renewable Energy Independent Power Producer Procurement programme.

So where does the 7GW come from? If in 2023 it was 4.4GW, in 2025 6.8GW in August of 2025, you're saying there was another surge in 2026?
The AI generated figures I could believe, that seems more logical, though not sure on the battery storage.
