Prepaid electricity sales back online
Johannesburg - Eskom's online vending system, which allows customers to buy pre-paid electricity, was back in operation on Friday, it said.
"Vending has been taking place normally for much of today [Friday] and progress has been made in stabilising the system," Eskom said in a statement.
"However the system continues to experience intermittent problems and customers may at times have difficulty purchasing pre-paid tokens."
The vending system was taken offline on Thursday night to allow Eskom to fix its problems.
Eskom said it was monitoring the performance of the system and had a team of experts working on finding the cause of the problems.
