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

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.
• • Rectification of infrastructure by ULBs
• • Full-scale Project implementation.

Key Points

• MAUD / ULBs to provide authorizations & approvals for full-scale Project
• Replacements on point to point basis
• Installation reports being signed by ULB daily basis
• Empty poles replacement shall be as per adjacent fixtures in the stretch or fixture rationing.
