Sasaram back to back HVDC converter station, HVDC back-to-back converter station in Sasaram, India.
The Sasaram back-to-back HVDC converter station is a power facility that connects alternating current and direct current systems in the Bihar region. The installation converts electrical energy between different current types and allows power to flow between separate grids that would otherwise remain isolated.
Construction of this 500 MW facility began in 1999 through a collaboration between Power Grid Corporation of India and Alstom, concluding in 2002. The station's role expanded after the merger of Eastern and Northern power grids in 2006, becoming a critical link between the combined grid systems.
The station represents the integration of modern power infrastructure within northeastern India's industrial development landscape.
The facility operates at a direct current voltage of 205 kV and carries a current rating of 2,475 amperes. Access to the station is limited due to its critical power infrastructure status and high-security requirements, typically requiring prior authorization for any visits.
Following the 2006 merger of Eastern and Northern power grids, the station adapted to function as an embedded power flow management device.
