EPC Line Project – 220kV LILO at Veraval Substation

Project Overview

This project involves the design, supply, erection, testing, and commissioning of a 220kV LILO (Line In Line Out) of one circuit from the existing 220kV D/C Visavadar–Timbdi line and 220kV S/C Keshod–Timbdi line at the proposed 220kV Veraval Substation, under the transmission circle of Junagadh.

The project is being executed for GETCO and aims to enhance the region’s transmission capacity, improve reliability, and ensure uninterrupted power flow to Veraval and surrounding industrial and coastal regions.

Status: Mobilization and Planning Phase

Scope of Work

  • Survey, design, and engineering of 220kV transmission line route.

  • Supply of towers, conductors (AL-59), and 48F OPGW cable for communication and protection systems.

  • Erection and stringing of M/C and D/C tower structures.

  • Testing and commissioning of the complete line to integrate with the Veraval Substation.

  • Quality assurance and safety compliance as per GETCO standards.

  • Coordination with substation and line teams for seamless grid integration.

Challenges

  • Managing long-distance line erection across varied topography and coastal conditions near Veraval.

  • Maintaining alignment precision between intersecting circuits from Timbdi and Keshod.

  • Ensuring synchronization with substation construction progress to avoid delays.

  • Meeting project milestones under challenging weather conditions in the coastal zone.

Solution

  • Deployment of advanced survey technology (GPS & total station) for route accuracy.

  • Strategic resource mobilization and phased construction plan to manage multiple work zones.

  • Close coordination with GETCO officials for real-time design validation and progress tracking.

  • Implementation of safety-first protocols and quality assurance systems to ensure reliability and efficiency.

Success Story

The 220kV LILO at Veraval Substation Project is a critical infrastructure upgrade for the Junagadh transmission circle, enhancing connectivity between existing power lines and new substations.

Upon completion, it will strengthen Gujarat’s western grid network, support industrial development in the coastal belt, and ensure reliable, high-capacity power delivery for years to come.

Key Highlights

  • Strategic 220kV LILO project strengthening the Junagadh transmission network.

  • 18.9 km line connecting Veraval Substation to Timbdi and Keshod lines.

  • Integration of AL-59 conductors and 48F OPGW cables for superior performance.

  • Enhances grid reliability, stability, and future scalability.

  • Executed under GETCO’s transmission modernization program.
