Eskom Data: November 2025

Eskom data - November 2025

End of Diesel? According to the data, we never generated more than 350MW with the OCGT backup generators, which is the lowest I have on record except for nov 2020 which might also be a glitch.

New installed renewable record of 7.5GW - looks like all those announced installations are slowly coming online. I'm not sure exactly when they count as 'installed' from.

Thermal is dropping, but that's a usual trend for this time of year. Hopefully it starts increasing from Jan->July again if we can keep squeezing the coal plants.

Koeberg second unit is back, so we have 900MW of extra baseload to play with which is nice (and maybe related to not needing the OCGTs?)

Interruption of Supply and Manual Load Reduction looking good. I always forget exactly what these are an how they relate with each other

IOS – Interruption of Supply: all contracted as well as mandatory demand reduction resources utilised by Eskom National Control. Includes IOS due to Transmission network faults.

MLR – Manual Load Reduction. An estimation of demand that has been reduced due to load shedding and/or curtailment.

so super clear? Anyway, nice that they're low.

wait there are three

ILS – Interruptible Load Shed. This is consumer load(s) that can be contractually interrupted without notice or reduced by remote control or on instruction from Eskom National Control. Individual contracts place limitations on usage.

still playing on easy mode because there's no demand, so let's see how that changes when the sun goes away and private solar turns off.
