 Introduction to C-II
 Introduction to Project
 Deliverables
Conclusion

3. Introduction to Project
QIP to Optimize DC Backup for OPEX
Saving
 Methods and Measures Used
 Importance of DC Backup
 OPEX Saving
 Distribution of the Project into
Deliverables

4. Deliverable 1
TITLE
Data to be Compiled for Each Site in C-II with
Site Status/Dependents
 Data Compilation
 Introduction to The Servers

5. Deliverable 1 (cont.)
Introduction to M2000

6. Deliverable 2
TITLE
Ensure Uniform availability of BB on all Urban
Sites with Healthy DGs. Also ensure Intelligent
timer's operation where PTML independent​​
 Site Visits
 Intelligent Timer

7. Deliverable 3
TITLE
Identify weak backup along with the options to
swap BB
 BB (Battery Backed-up) Issues
 Monitoring of Weak Backup
on the server

8. Deliverable 3 (cont.)
Reasons and Effects of Low Battery Voltages
Battery Voltage
Level
BTS position
-53V to -47V The site runs normally
-46V The site gives Low Battery Voltage Alarm,
and most of the times, the BTS itself is
down but if it is a HUB site, it maintains
the ongoing traffic
-43.5V At this level the BTS is completely on
outage i.e. MW links are also Disabled

9. Deliverable 4
TITLE
Major HUB, PTCL Guest, DC Shared, Low Voltage
Area, Problematic Owner, Fuel theft etc... sites to
be secured for better availability
 Priority of Sites
 Importance of Healthy DG’s and BB on Priority
Basis

10. QIP Proposal
Current Power Problems in Telecom Sector
Power availability is a major challenge
Rural areas conventional grid power not
available (Sahiwal: 4531)
Wherever WAPDA supply is available, power
quality is poor and erratic
Power availability is less than 12 hours a day in
rural areas and up to 18 hours in urban areas

11. QIP Proposal (contd.)
Backup Plans for Maintaining Continual
Service
DG Set+ Its Limitations
Number of BTS
sites in C-II
929
DG Diesel
Consumption
~=
2.75Litres/hour
DG running hours 8-12 hours/ day
if BB is not
available
1 liter diesel emits 2.68kg of CO2

12. QIP Proposal (contd.)
Backup Plans for Maintaining Continual
Service
Inverter Battery Backup (BB) + Its Limitations

13. QIP Proposal (contd.)
Alternate Power Solutions(Importance)

14. QIP Proposal (contd.)
Alternate Power Solutions
Solar Photo Voltaic (SPV)
Wind Turbine Generator
Fuel Cells
Bio Mass
Hybrid Solutions

15. QIP Proposal (contd.)
Suitable Energy Resource for C-II
Solar Energy???

16. QIP Proposal (contd.)
How SPV Cells Can Help to get
High CAPEX & Low OPEX?
1KWp SPV cell generates 3.5 to 4 kWh/day
Area Required for installation: 10-12 sq mt /Kwp SPV
No maintenance required (only cleaning of panels is
necessary)
Cost of Installation: $2000/KWp
Life up to 25 Years
Payback period: approximately 4 years

17. QIP Proposal (contd.)
Case study
 There are Solar Powered Sites in Pakistan such as in
Bahawalpur, C-III.
Site 5338 in C-II
is solar powered
 The Case Study
Presented here is
from Indian State
Karnataka.

18. QIP Proposal (contd.)
Case study
 Site Description

19. QIP Proposal (contd.)
Case study(Installation)

20. QIP Proposal (contd.)
Case study(OPEX Comparison)

21. QIP Proposal (contd.)
Case study(Pay Back Period)

22. QIP Proposal (contd.)
 Conclusions from The Case Study
 To what extent is this possible to introduce
the same in C-II sites?

23. Conclusion
 Importance of QIP
 Converting Solar Energy to Electricity,
Remarkable Solution in Remote Sites
 SPV’s, A solution to Increasing Carbon in Air
 Low OPEX of SPV installation makes it
Attractive for Telecom Sector But Operators
Look for Incentives from the Government due to
High CAPEX of its Installation
 OPEX vs. CAPEX
