Power transmission capacity hits 5 lakh circuit km; transformation capacity at 1,407 GVA

New Delhi: India's power transmission network has crossed five lakh circuit kilometres (ckm) with transmission lines of 220 kV and above, while total transformation capacity has reached 1,407 gigavolt ampere (GVA), the power ministry said on Thursday.

The latest addition to the network was commissioned on January 14, when a 765 kV transmission line between Bhadla-II and Sikar-II substations in Rajasthan was brought into service.

The 628 ckm line will facilitate the evacuation of an additional 1,100 MW of electricity from the Bhadla, Ramgarh and Fatehgarh solar power complexes, which together form one of the country's largest renewable energy zones. The corridor adds to transmission connectivity from western Rajasthan, a major region for solar power.


Transmission lines of 220 kV and above have increased by 2.09 lakh circuit kilometres, up 71.6% since 2014.

Over the same period, transformation capacity has risen by 876 GVA.

Inter-state transmission projects currently under implementation are expected to add about 40,000 ckm of transmission lines and 399 GVA of transformation capacity.

In addition, intra-state transmission projects are set to contribute another 27,500 ckm of lines and 134 GVA of capacity, aimed at strengthening grid reliability and power evacuation. The ministry said that the planned additions were aligned with the increase in non-fossil fuel-based generation capacity of 500 GW by 2030.
