Route Length: 2.463 KM

Completion Status: 88.64% Completed | 11.4% Pending

Scope of Work

The project involves full turnkey execution, including:

  • Supply, erection, testing, and commissioning of LILO of both circuits of the existing 220kV Motipaneli–Sardargadh D/C line.

  • Construction using 220kV M/C (Multi-Circuit) towers with AL-59 (61/3.50) conductors.

  • Installation of 48F OPGW (Optical Ground Wire) cable to support advanced communication and protection systems.

  • Integration of the LILO section with the proposed Dhank Substation under the KSY-II scheme.

  • Ensuring safety, quality, and compliance with GETCO’s engineering standards.

Challenges

  • Managing project timelines within a tight 6-month delivery period.

  • Coordinating with live transmission infrastructure during LILO execution.

  • Navigating logistical constraints due to short route length and limited access corridors.

  • Maintaining quality and safety standards while working in operational zones.

Solution

Concord Construction employed an agile execution approach emphasizing precision and speed:

  • Detailed Planning and Scheduling to align with GETCO’s operational requirements.

  • Simultaneous Supply and Erection Execution to optimize time and ensure timely delivery.

  • Deployment of Skilled Engineers and Linemen specialized in 220kV M/C tower erection and OPGW stringing.

  • Use of Modern Equipment and Monitoring Tools for efficient resource management and quality assurance.

  • Strict Adherence to Safety Protocols ensuring zero-incident execution.

Success Story

Achieving over 88% completion within just a few months, the project demonstrates Concord’s commitment to efficiency, reliability, and engineering excellence.

Once operational, this LILO connection will provide enhanced power stability and connectivity to the Dhank region, significantly improving the transmission network’s flexibility and reliability under the KSY-II development scheme.
