The current prepaid electricity voucher system will run out of voucher sequences for the unique tokens produced specifically for each meter by the 24th of November 2024. The TID (Token Identifier) system is a security measure that ensures that a token can only be used once and for the meter number it was purchased. 

This means that token purchased after this date will not be recognized by the current prepaid meter installed since 1993. In resolving this system issue, City Power will embark on a programme to upgrade Smart meters or replace older meters.

“This is a system linked limitation and not unexpected, however with the recent articles published in the media, it has caused quite a panic in the public space. We certainly do not want to scramble at the last minute and want to ensure that prepaid electricity customers continue to receive services when the new system kicks in towards the end of 2024” said MMC Michael Sun

The current Standard Transfer Specification (STS) system has been in place since 1993 and will stop dispensing voucher sequences on 24 November 2024. The STS provides the facility of generating tokens which can only be used by the intended meter, and in the case of credit tokens, can only be used once in that meter.

“When the time comes, the prepaid meters will stop accepting new credit tokens and will then stop dispensing electricity after the existing credits are used up” said MMC Sun 

Any tokens generated after this date and utilizing the 24- digit number will be rejected by the meters as being old tokens

“I urge customers with the affected meters in Johannesburg to cooperate with the City Power officials when they arrive on your premises to upgrade or replace your meters.” said MMC Sun
