India’s national power transmission network has ?????? achieved a major milestone, crossing more than 500,000 circuit kilometres (ckm) of transmission lines at 220 kV and above, along with 1,407 GVA of transformation capacity at 220 kV and above. The world’s largest synchronous national grid reached this landmark on January 14, 2026, with the commissioning of a 628 ckm, 765 kV transmission line from Bhadla II to Sikar II substation for the 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 now be evacuated from the renewable energy zones of Bhadla, Ramgarh and the Fatehgarh Solar Power Complex, strengthening grid integration for large-scale clean energy generation in the region.

Since April 2014, India’s transmission network has expanded by 71.6 per cent, with the addition of around 209,000 ckm of transmission lines (220 kV and above), while transformation capacity has increased by 876 GVA. This rapid expansion has significantly strengthened the country’s power infrastructure and enhanced grid reliability.

The inter-regional power transfer capacity now stands at 120,340 MW, enabling seamless electricity flow across regions and successfully realising the vision of “One Nation – One Grid – One Frequency”. The continued expansion of transmission capacity will play a critical role in evacuating rising non-fossil power generation, supporting India’s target of achieving 500 GW of non-fossil energy capacity by 2030.

The milestone reflects India’s strategic focus on building a resilient, future-ready power grid capable of supporting large-scale renewable energy integration and long-term energy security.
