Implementation Plan

Proposed to be implemented in two phases:

Phase -1: Implementation of Pilot stretches in 12 ULBs

Phase -2: Implementation of full scale Project in 12 ULBs

Objectives of Pilot :

To understand the practical issues while at site and incorporate

the rectifications in full-scale project

To demonstrate energy consumption, savings and monitoring of

the same which would form basis for annuity payments to EESL

in full-scale project

Implementation Steps

Rectification of infrastructure by ULBs based on survey findings

EESL to initiate installations in ULBs, for Phase-1

Demonstration for 15 days; 7 days for each existing & retrofit fixtures

Rectification of infrastructure by ULBs

Full scale Project implementation

Survey of balance street lights to identify infrastructure requirements

Key Points

• MAUD / ULBs to provide

authorizations & approvals

for full scale Project

• Replacements on point to

point basis

• Installation reports to be

signed by ULB daily basis

• Empty poles replacement

shall be as per adjacent

fixtures in the stretch or

fixture rationing

FINDINGS

• Average operating hours in 4

municipalities is < 50%.

• In fact, except for Karimnagar,

the operating hours are way

below 80%. The following are the

possible causes for such high

downtime :

o Non – working lights

o Improper lamp operation

o faults in cables, fuses, etc

o power availability

• Siddipet : Operating hours are

at 289% (~ 32 hours daily).

Energy consumption is 2.57 lakh

units against computed 0.89 lakh

units

• This is technically not possible,

except for the following reasons :

o Pilferage and power theft

o Mixed load connected to

meter

• Cost per unit electricity is in ranging from Rs 7.22 / unit to Rs 10.76 / unit.

• Possible reasons are : Additional charges on account of low power factor, interest

charges & low connected load

• Electricity duty : 6 paise / unit

» » 12 hours operation, energy consumption would be 3.38 MUs; instead of 1.72

MUs as per bills
