Powergrid Narela Transmission, a wholly-owned subsidiary of Powergrid Corporation of India (Powergrid), has commissioned an interstate transmission system (ISTS) in Rajasthan that will enable the evacuation of 8.1 GW of power from solar energy zones in the state. This marks the completion of the project awarded under the national transmission plan for renewable energy integration (Phase II Part G). The solar power will be evacuated through high-capacity 765 kV corridors and enhance overall grid stability.
The project was secured by Powergrid Narela Transmission through tariff-based competitive bidding carried out by PFC Consulting. The transmission system will function under a build, own, operate, and maintain model. The scope of work covers the establishment of a new 765/400 kV gas-insulated substation (GIS) at Narela, Delhi. The GIS will have a transformation capacity of 3×1,500 MVA, along with associated bus reactors and line bays. The transmission system also involved the construction of the Khetri–Narela 765 kV double-circuit transmission line spanning 180 km, along with the establishment of two 765 kV line bays at Khetri. Additionally, it included the loop-in and loop-out of the 765 kV Meerut–Bhiwani single-circuit transmission line at the Narela substation.
Earlier this month, Powergrid completed the acquisition of Bellary Davanagere Power Transmission Limited, the special purpose vehicle set up for the transmission project in Karnataka to facilitate the evacuation of about 0.25 GW of renewable energy at Davanagere and 2.75 GW at Bellary.
