India’s national power transmission network has achieved a major milestone, crossing over 500,000 circuit kilometres (ckm) of transmission lines (220 kV and above) along with a transformation capacity of 1,407 GVA (220 kV and above).
This landmark was achieved by the world’s largest synchronous national grid on 14 January 2026, with the commissioning of a 765 kV, 628 ckm-long transmission line from Bhadla-II to Sikar-II substation for evacuation of renewable energy from the Rajasthan Renewable Energy Zone. With the commissioning of this transmission line, an additional 1,100 MW of power can be evacuated from the renewable energy zones of the Bhadla, Ramgarh, and Fatehgarh solar parks.
Since April 2014, the country’s transmission network has expanded by 2.09 lakh ckm of transmission lines (220 kV and above), registering a growth of 71.6 per cent, along with an addition of 876 GVA in transformation capacity (220 kV and above). The inter-regional power transfer capacity, which now stands at 120,340 MW, has enabled seamless transfer of electricity across regions, successfully realizing the vision of “One Nation – One Grid – One Frequency.”
Inter-State Transmission System (ISTS) projects currently under implementation will add approximately 40,000 ckm of transmission lines and 399 GVA of transformation capacity. In addition, upcoming ISTS projects are expected to further add about 27,500 ckm of transmission lines and 134 GVA of transformation capacity, significantly enhancing grid reliability and power evacuation capability.
The expansion of transmission capacity will support the increasing generation of electricity from non-fossil fuel sources, in line with the national target of achieving 500 GW of non-fossil fuel-based installed capacity by 2030.
