India has crossed five lakh circuit kilometres of high-voltage electricity transmission lines, marking a significant step in strengthening its power infrastructure. The milestone was achieved after a new 765 kV line in Rajasthan became operational, enabling additional evacuation of renewable energy from major solar zones. Since 2014, the transmission network has expanded sharply, boosting transformation and inter-regional transfer capacity. Ongoing transmission projects are expected to further support renewable energy growth and help meet the national target of 500 GW of clean energy by 2030.
India's electricity transmission network has crossed a major infrastructure milestone, with the total length of high-voltage transmission lines reaching over five lakh circuit kilometres. The network has the capability to carry power at 220 kilovolts and above, supported by a transformation capacity of 1,407 gigavolt amperes, according to the Union power ministry. Advertisement
The achievement was recorded after the commissioning of a 765 kV transmission line connecting Bhadla II and Sikar II substations in Rajasthan. This 628 circuit kilometre line was developed to facilitate the evacuation of renewable power from the Rajasthan Renewable Energy Zone, a key hub for solar generation in the country.
With this transmission line becoming operational, an additional 1,100 megawatts of electricity can now be transmitted from the Bhadla, Ramgarh and Fatehgarh solar power complexes. These regions form one of India's largest clusters of solar projects and play a central role in meeting clean energy targets.
The ministry highlighted that India operates the world's largest synchronous national grid, allowing electricity to flow smoothly across states and regions. Since April 2014, the country's transmission network has expanded by 71.6 per cent, with 2.09 lakh circuit kilometres of new lines added and transformation capacity increased by 876 GVA.
Inter-regional power transfer capacity has risen to 1,20,340 megawatts, enabling electricity generated in one part of the country to be supplied efficiently to another. This expansion has helped turn the long-term vision of a unified national grid with a single frequency into a functional reality.
Several inter-state transmission projects are currently under implementation and are expected to add nearly 40,000 circuit kilometres of transmission lines along with 399 GVA of additional transformation capacity. These projects are designed to support the rising share of non-fossil fuel-based power generation.
The ministry noted that the strengthened network will play a crucial role in evacuating renewable energy as India progresses towards its target of achieving 500 gigawatts of renewable energy capacity by 2030.

FAQ
Q1. What major milestone has India's power transmission sector achieved?
India's high-voltage electricity transmission network has crossed five lakh circuit kilometres, marking a significant expansion of the country's power infrastructure. The network carries electricity at 220 kilovolts and above and is supported by a transformation capacity of 1,407 gigavolt amperes, reflecting the scale and readiness of the national grid.
Q2. What development led to this milestone?
The milestone was achieved following the commissioning of a 765 kV transmission line between the Bhadla II and Sikar II substations in Rajasthan. Spanning 628 circuit kilometres, the line was developed specifically to enable faster and more reliable evacuation of renewable energy from the Rajasthan Renewable Energy Zone.
Q3. How does this benefit renewable energy transmission?
With the new line becoming operational, the system can now transmit an additional 1,100 megawatts of power from the Bhadla, Ramgarh and Fatehgarh solar complexes. These areas form one of the largest solar generation clusters in India and are critical to scaling up clean energy supply.
Q4. How has the transmission network evolved since 2014?
Since April 2014, India's transmission network has expanded by 71.6 per cent. During this period, 2.09 lakh circuit kilometres of new transmission lines were added, while transformation capacity increased by 876 GVA. This rapid growth has strengthened grid stability and improved power availability across regions.
Q5. What is the significance of inter-regional power transfer capacity?
Inter-regional transfer capacity has risen to 1,20,340 megawatts, allowing electricity generated in one region to be efficiently supplied to another. This capability underpins India's status as the world's largest synchronous national grid and ensures smoother power flow with a single national frequency.
Q6. What projects are currently underway?
Several inter-state transmission projects are under implementation and are expected to add nearly 40,000 circuit kilometres of new lines along with 399 GVA of additional transformation capacity. These projects are aligned with the rising share of non-fossil fuel-based power in the national energy mix.
Q7. How does this support India's long-term energy goals?
The strengthened transmission network will play a central role in evacuating renewable energy as India moves towards its target of 500 gigawatts of renewable energy capacity by 2030. Improved grid infrastructure is expected to ensure reliable integration of large-scale solar and wind power into the national system.
