Power was later restored to only certain parts of Middelburg, leaving areas like Gholfsig, Mhluzi and other suburbs connected to the substation without electricity.

It remains unclear what led to the explosion and it is expected that these areas will be without electricity for days.

*This explosion follows on a previous electrical fire that occurred at the same substation in December 2019, which left residents without electricity for four days.

Parts of Dennesig and Kanonkop were also without electricity earlier this week due to vandalism at the Dennesig substation.
