What counts as load shedding here

These figures count Eskom's manual load reduction only, the scheduled outages households and businesses experience. Eskom also curtails large industrial customers who are paid to be interruptible, and that demand management is reported separately on this site, never as load shedding. One stage of load shedding is roughly 1 000 MW, so a peak cut of 6 800 MW corresponds to about stage 7.
