Johannesburg - Power utility Eskom on Friday confirmed it has implemented stage 1 rotational load shedding.
The parastatal said the decision to implement stage 1 as opposed to stage 2 was due to an "small improvement in generation performance and because of lower electricity demand on Fridays".
Stage 1 calls for 1000MW to be rotationally load shed nationally at a given period.
Load shedding is conducted rotationally as a measure of last resort to protect the power system from a total collapse or blackout.
Load shedding began at 9am and is expected to end at 10pm.
