India’s national power transmission network has crossed a major milestone, surpassing 5 lakh circuit kilometres (ckm) of transmission lines (220 kV and above), along with a transformation capacity of 1,407 GVA (220 kV and above). The achievement underscores the rapid expansion of the country’s grid infrastructure to support rising electricity demand and renewable energy integration.
The milestone was achieved on 14 January 2026 with the commissioning of a 628 ckm, 765 kV transmission line from Bhadla II to Sikar II substation. This line has been developed to facilitate the evacuation of renewable energy from the Rajasthan Renewable Energy Zone and enables the additional evacuation of 1,100 MW of power from the Bhadla, Ramgarh and Fatehgarh Solar Power Complex.
Since April 2014, India’s transmission network has expanded by 71.6%, with the addition of 2.09 lakh km of transmission lines (220 kV and above). During the same period, transformation capacity has increased by 876 GVA. The inter-regional power transfer capacity has now reached 1,20,340 MW, enabling seamless electricity transfer across regions and supporting the vision of “One Nation – One Grid – One Frequency.”
Further strengthening of the grid is underway through Inter-State Transmission projects currently under implementation, which are expected to add around 40,000 ckm of transmission lines and 399 GVA of transformation capacity. In addition, Intra-State Transmission projects under execution are set to contribute another 27,500 ckm of transmission lines and 134 GVA of transformation capacity, enhancing grid reliability and power evacuation capability.
The expansion of transmission capacity is critical to supporting the evacuation of increasing non-fossil power generation, which is targeted to reach 500 GW by 2030. The achievement of 5,00,000 ckm of transmission lines reflects the Government’s sustained efforts to ensure a reliable, affordable and secure electricity supply across the country while enabling rapid growth in renewable energy integration.
