India’s national power transmission network has achieved a significant milestone, crossing over 5 lakh circuit kilometres (ckm) of transmission lines (220 kV and above) along with 1,407 GVA of transformation capacity (220 kV and above).

The world’s largest synchronous national grid achieved this feat on 14th January 2026, with the commissioning of 628 ckm Transmission Line of 765 kV from Bhadla II to Sikar II substation for evacuation of RE power from Rajasthan Renewable Energy Zone.  With commissioning of this transmission line additional 1100 MW of power can be evacuated from RE zone of Bhadla, Ramgarh & Fatehgarh Solar Power Complex.

Since April 2014, the country’s transmission network has grown by 71.6% with the addition of 2.09lakh ckm of transmission lines (220 kV and above), boosting transformation capacity (220 kV and above) by 876 GVA. The inter-regional power transfer capacity, which now stands at 1,20,340 MW, has enabled seamless transfer of electricity across regions, successfully realizing the vision of “One Nation – One Grid – One Frequency.”

The Inter State Transmission projects presently under implementation, will add approximately 40,000 ckm of transmission lines and 399 GVA of transformation capacity, In addition to these, the Intra State Transmission projects under implementation are expected to add another 27,500 ckm of transmission lines and 134 GVA of transformation capacity, which will further enhance grid reliability and power evacuation capability.

The addition to the transmission capacity will help to evacuate the increasing non-fossil power generation which is targeted at 500 GW by 2030.

The milestone of 5,00,000 ckm of transmission lines reflects the Government’s sustained efforts towards ensuring reliable, affordable, and secure electricity supply across the country while supporting rapid growth in renewable energy integration.
