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

Deliverable 1

TITLEData to be Compiled for Each Site in C-II with

Site Status/Dependents

Data Compilation Introduction to The Servers

Deliverable 1 (cont.)

Introduction to M2000

Deliverable 2

TITLEEnsure Uniform availability of BB on all Urban Sites with Healthy DGs. Also ensure Intelligent

timer's operation where PTML independent

Site Visits Intelligent Timer

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

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

Deliverable 4TITLE

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

QIP Proposal

Current Power Problems in Telecom Sector

Power availability is a major challengeRural areas conventional grid power not available (Sahiwal: 4531)Wherever WAPDA supply is available, power quality is poor and erraticPower availability is less than 12 hours a day in rural areas and up to 18 hours in urban areas

QIP Proposal (contd.)

Backup Plans for Maintaining Continual Service

DG Set+ Its LimitationsNumber 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

QIP Proposal (contd.)

Suitable Energy Resource for C-II

Solar Energy???

QIP Proposal (contd.)How SPV Cells Can Help to get

High CAPEX & Low OPEX?

1KWp SPV cell generates 3.5 to 4 kWh/dayArea Required for installation: 10-12 sq mt /Kwp SPVNo maintenance required (only cleaning of panels is necessary)Cost of Installation: $2000/KWpLife up to 25 Years Payback period: approximately 4 years

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.

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

QIP Proposal (contd.)

Conclusions from The Case Study To what extent is this possible to introduce the same in C-II sites?

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
