Project Story

The Raigarh pool in Chattisgarh had been facing high-fault levels and this project aims at creating an alternative path of evacuation. The project will help address the quality of power transfer from generating stations connected to the Raigarh pool to Goa.

This project is spread across the state of Goa, Karnataka and Chattishgarh and passes through the heavy dense forest of the Western Ghats in Goa & Karnataka. Our robust surveying methods ensure that the above challenges are kept to a minimal. Multiple teams are working with different stakeholders to get timely permissions pertaining to ROW.

Project Detail

The Project entails the laying of 245 Kms of transmission lines and one high-power sub-station aiming to strengthen the current grid network. The Project comprises of four elements:

  • Construction of a sub-station at Goa with a 220 KV double circuit line of 29 Kms
  • Laying of a 400 KV double circuit line of 52 Kms spread across Goa
  • Laying of another 400 KV double circuit line of 94 Km spread across Goa and Karnataka
  • Construction of 765 KV double circuit line of 70 Km in Chattisgarh.

The overall Project is expected to be commissioned in 44 months.
