The HVDC Sileru–Barsoor is a high voltage direct current transmission system between Sileru, India and Barsoor, India, which went in service in 1989 as the first HVDC line in India. The HVDC Sileru–Barsoor is a bipolar HVDC with a voltage of 200 kV and a transmission rate of 400 megawatts. The HVDC Sileru Barsoor couples two asynchronously operated parts of Indian electricity mains over a 196 kilometers long overhead line, which was originally a double-circuit 220 kV AC line from which three conductors are parallelized.

On 1 January 2014, The NEW grid is synchronised with the Southern regional grid making this HVDC link redundant. 200 KV AC line of NEW grid can be directly connected to the 200 KV line of Southern grid bypassing the HVDC converter stations. Thus the energy losses taking place in the converter stations can be avoided and these HVDC converter stations can be shifted to elsewhere to export/import power from other countries.
