8. Data Reading for old system
Reading
Highly person dependent.
Accessibility of meter Reading in rural /remote
zones.
Billing done mainly on estimated / average basis
Inability to monitor and control discrete loads
Billing cycle requires excessive time.

Modes of Communication in AMR
1. GSM Based Communication
• Single stage communication between Meter and
central station through GSM Modem
2. Radio frequency network
• Radio frequency based AMR (handheld,
mobile/drive by, and fixed (Star/Mesh networks)
3. PLC Based Communication
• Electronic data transmitted over power lines -- the
network being the distribution network which the
utility has built and maintains to deliver electric
power.
4. Hybrid Communication
• Two stages of communication in AMR System

Calculate transformer loading and sizing from interval
data
15 minute interval data gives accurate load information
for supply scheduling, switching operations, planning etc
Monitor voltage at each premise to know conditions
when to operate capacitor switches or regulators
Critical Benefits Of AMR
15. Which consumers require extra vigilance on account of high
commercial losses?
Which consumers have violated sanctioned demand more
than 3 times in the last month?
Which network nodes have reported more than 1 outage
event last week?
How can I accurately reconcile all my bills with actual
consumption?
How can I reduce system peak load through feeder
reconfiguration?
Benefits of AMR – Contd…
16. The Pilot AMR was started in Sector G-6/3 of G-6 sub division
Islamabad circle Islamabad in 2008.The purpose was to check the
results/benefits for future planning.
But due to some reasons it could not be completed till 2010
when Worthy CEO appointed me as SDO G-6 sub division with
task to complete the AMR project and to bring the reading
online(human free) in collaboration with Manager (MIS) and M/s
Telco net .
Task assigned
17. IESCO AMR Project
The Situation was
Meters Installed
Single Phase : 124
Three Phase : 249
CT Meter : 4
Transformers : 23
Total : 400
But proper network was not established so reading
was still taken manually by the meter readers .
18. IESCO AMR Project
Reasons were
I studied the case thoroughly and sort out that
Some of the meters installed were defective
whereas some meters were not responding due to
fault in Fire Fly (a unique identification of meter).
Gate way installed was not at the proper location
resulting slow/disturbed signal.
19. IESCO AMR Project
What I Did
I established team of trained staff who installed those meters.
Visited each and every meter at site.
Removed discrepancies i.e. burnt meters, replacement of
meters with defective fireflies.
Coding of transformers for calculating T/F losses.
IESCO AMR Project
20. IESCO AMR Project
What I Did
Feeding of transformer wise consumers.
Meeting s with different suitable building owners for relocation
of gateway.
Relocation of Gate way at suitable building which resolved the
problem of data transfer
IESCO AMR Project
21. IESCO AMR Project
• These Steps taken resolved the problem and data transfer
through AMR started and reading was done succesfully
without meter readers just on internet.
• These efforts were highly appreciated by worthy CEO of
IESCO.
• I was nominated for training on AMR in Thailand.
• I am also included in the committee constituted for purchase
of 300,000 AMR meters through ADB loan.
• I have been taken as member of working committee to
finalize the specification of AMR meters to be purchased
through USAID and ADB.
Achievements/Rewards
22. IESCO AMR Project
Results Net Improvement: 3,79,111 KWH over 12
months Revenue Generated @ Rs 8.33 per unit =
31,57,944.63 PKR Project ROI in 23 Months
Enhancement through AMR
Result
‘‘Service and Technology
23. IESCO AMR Project
Nothing is impossible if you work hard with
consistency.
If one is determined to his goals and work hard
devotedly he can achieve the Targets.
Team work and positive approach is the key of
success.
Enhance managerial skills.
CONCLUSION
24. IESCO AMR Project
It is suggested that hard to reach areas and
sensitive installations such as Parliament lodges,
atomic installations ,embassies etc should
immediately be shifted on AMR GSM based
networks so that manual system be eliminated at
once in order to avoid the errors and ensure
security and to save the precious time of IESCO’s
officers
