The award comes amid continued expansion of India’s transmission network to integrate large-scale renewable power generation.
Transmission Project to Strengthen Renewable Power Evacuation
The transmission system will facilitate the evacuation of renewable power and support its integration with the national transmission grid.
The project will also strengthen inter-state power transfer capacity as renewable generation expands across Gujarat and other regions.
The new Alephata substation and associated transmission lines will add to the infrastructure required for reliable power evacuation.
