Today is Eskom's deadline to update electricity meters across the country. This entails the introduction of a new series of electricity vending codes to all meters in South Africa. The aim of the change is to  ensure that the meters' key change code does not expire. Eskoms says Zero buyers can still go to their legal vending sites with their meter numbers to buy electricity. They will then be issued their Key Change Tokens by the vending agents to make their meters KRN2 compliant.
