It’s been six days since a fire at a substation in Eldorado Park left large sections of Johannesburg without power. And, to make matters worse, an explosion at the same substation could lead to another seven days of work before the electricity is fully restored. The fire, which initially started at around 05:00 on Friday, caused widespread power outages and water cuts in Johannesburg. City Power had hoped to restore the electricity on Wednesday, but the explosion could have derailed that plan.
