Many end-users have poor awareness of their consumption, and a considerable part of the existing electricity infrastructure still needs to be manually verified.

  • Customers often poorly understand their own consumption
  • Paper bills are cumbersome and unsustainable
  • Old meter infrastructure must still be checked manually

Our smart prepayment solution simplifies administrative work and minimizes customer complaints with automated billing, paperless payment, and flexible payment options.

Solution architecture


  • A customer interface unit (CIU) communicating with a metering unit by MBUS, RF, or PLC for energy consumption and credit balance monitoring, credit limitation alarming, and credit charging
  • Smart prepaid energy meters (smart prepaid gas meters, smart prepaid water meters, smart prepaid electricity meters), single or 3-phase devices measuring consumption per residence
  • A data concentrator unit (DCU) collecting data from a group of smart prepaid electricity meters, usually through G3-PLC communication
  • A network connecting the DCUs with the data center / WebClient (or POS) through either GPRS or ethernet communication.


  • Web Client, a workstation registered in the system that can charge customers, display reports, communicate with the prepay smart meters, etc.


  • Data center and head office, a virtual infrastructure for housing computers, servers and networking systems, software systems and company’s IT needs, a platform or database and application in our smart prepayment solution.
