The Sasaram back to back HVDC station is a back to back HVDC connection between the eastern and northern regions in India, located close to the city of Sasaram, in Bihar state in northeastern India. The station is owned by Power Grid Corporation of India.
The converter station consists one pole with a nominal power transmission rating of 500 MW. The converter station was built by Alstom between 1999 and 2002 and has nominal DC voltage and current ratings of 205 kV, 2475 A.[1] The design is very similar to that of the Chandrapur and Vizag 1 converter stations also built for Power Grid.
Both Eastern and Northern regions are made part of NEW grid making this converter station redundant. 200 KV AC line of both grids can be directly connected bypassing the HVDC converter station. Thus the energy losses taking place in the converter station can be avoided and these converter station can be shifted to elsewhere to export/import power from other countries.
