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.

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

NDPL has AMR enabled meter base of 25000
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.
Limitations




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.
A weapon in war is a wish to destroy, not a
weapon itself.
In war, there is no substitute for victory.
