As of 12:00 on 8 May 2023, Stage 6 loadshedding is the highest stage of loadshedding to be implemented in South Africa. Stage 7 or 8 load-shedding have never been implemented. The NRS048-9 Code of Practice differentiates between loadshedding and load curtailment, the latter being the instructed, partial reduction of demand from large industrial customers. On occasion, load curtailment, up to Stage 4, has been implemented in conjunction with Stage 6 loadshedding. Each stage of load curtailment is approximately 5% of the large customer demand with Stage 4 load curtailment being up to 1000MW of demand that is removed from the power system.
