Eskom Data: May 2025

Eskom data - May 2025

• Unplanned outages still looking bad
• Small bump from new wind installations
• Diesel use trending down again

🧵

Planned maintenance is dropping (as expected as we head into colder months), which increases EAF, but not in the good way - unplanned outages still at 13.4GW - slightly higher than last month.

Thermal generation is up a bit, slightly higher than a year ago, and best so far this year, but looking a bit doubtful we will get back to a regularly >22GW peak from last winter.

New wind installations are helping a bit - highest peak of 3.2GW (from an installed base of 3.7GW), and ~200MW more on average than this time last year is nice to see

Still using those diesel generators for generating up to 3GW during peaks, but on average looking better than the last two months.

Exports up a bit - higher than May 2024, but still far below the November peak

Overall generation and demand is flat and the same as last year, so take your pick on whether the glass is currently half full or half empty I guess 🙃

As always - this data and more available on my site, unofficialeskom.com.
