The Talcher–Kolar HVDC system, otherwise known as the East–South interconnection II is a 1450 km HVDC transmission connection between the eastern and southern regions in India connecting four states namely Odisha, Andhra Pradesh, Tamil Nadu and Karnataka. The system has a transmission voltage of ±500 kV and was originally put into service in March 2003, with a rated power of 2000 MW. In 2007 the scheme was upgraded to 2500 MW.
The Talcher–Kolar HVDC system is owned by Power Grid Corporation of India and the converter stations were built by Siemens.
The scheme is a conventional bipolar system with overhead lines for the high-voltage conductors and ground return for the neutral current.
