AMR & Meter data interoperability B.N. Prasanna North Delhi Power Ltd.

 Usage of Static meters data storage capability for utility needs/ Challenges.  Many makes of meters in use – Different methods of data storage and data transfer.  Meter vendor Software deals with same information in different formats.  Different S/W needs parallel processes and leads to duplication of work.  Meter Vendor S/W cant be customized and utility needs are dynamic.  Protect investments through common IT infrastructure.

 Common Language Translated Language Language A Language B Language C  Translator approach ◦ APIs ◦ Universal meter reading format. ◦ IT support H/W & S/W

Interoperability

 Data calling by one S/W  All meters data in to one format Interoperability

 Improved accuracy of billing and better Revenue Cycle Management.  Automatic data analysis and theft detection for loss reduction.  Simplify complex processes of billing and data analysis process through complete automation.  Flexibility to add new version of meters or new make of meters. Advantages

 NDPL has AMR enabled meter base of meters of three different meter makes.  Common S/W for data collection, processing and analysis developed jointly by NDPL and CMC.  This S/W uses APIs for reading and data conversion of different meters into common data format.  Automatic data analysis through system as per schedules.

 Selective data collection from meters is not possible.  APIs cant be used to limited programming of meters.  Standards for performance and testing of API are not available.  Trouble shooting / improving performance of API always necessitates support from meter supplier. Limitations

In war, there is no substitute for victory. A weapon in war is a wish to destroy, not a weapon itself.
