State-owned power utility Eskom says bulk electricity supply to Jagersfontein, in the Free State, was restored at 04:25 on September 14.
Eskom delivers electricity in bulk to Centlec, which then distributes it to Jagersfontein and Charlesville. A tailings dam burst on September 11, damaging homes and infrastructure in the area.
"Eskom technicians worked around the clock to install and energise a replacement transformer at Badplaas substation, in Jagersfontein, after Rietkuil substation was destroyed on Sunday, September 11, when mud burst through a broken wall of a nearby mining dam, flooding the area.
"Although we aimed to restore supply before midnight on Tuesday, September 13, minor complications delayed the recovery process," the utility says.
