220kV Dhank Substation – Civil & Erection Works

Project Overview

This project involves complete development of the 220kV Dhank Substation, including civil infrastructure construction and erection of all primary and secondary electrical equipment under GETCO. The civil scope ensures durable foundations, control rooms, residential quarters, and essential substation structures. The erection phase transforms the civil works into a fully operational high-voltage substation capable of enhancing regional transmission reliability.
