The about 200 km long HVDC connection will be India's first direct current link using voltage-sourced converter (VSC) technology. VSC is the latest innovation in HVDC technology offering a very stable and highly-flexible reactive power control independent of active power control and additional features to support the AC systems like blackstart capability. Furthermore, this solution is ideal to be combined with XLPE cable technology.

Siemens will be supplying two converter stations with two parallel converters, each rated 1000 Megawatts (MW), using its VSC HVDC technology while Sumitomo Electric will be responsible for XLPE HVDC cables in the DC circuit. The grid connection is scheduled to go into operation in the first half of 2020.
