The City of Tshwane says technicians are working around the clock to restore power to areas affected by a fire incident at the Olivenhoutbosch substation in the early hours of Thursday morning. Some of the affected areas include Zwartkop, Highveld and Eco Park.
The fire was caused by cable theft resulting in damage to critical electrical equipment.
City of Tshwane Spokesperson Lindela Mashigo says the restoration might take several days to complete.
