Maharashtra State Electricity Board (MSEB) of India have constructed a 1500 MW HVDC link between Chandrapur and Padghe near Mumbai (Bombay). The converter terminals have being constructed by ABB (Sweden and India) and Bharat Heavy Electricals Limited (BHEL) of India.

The 500 kV Chandrapur - Padghe HVDC Bipole feeds Mumbai with 1500 MW from the thermal generation plant located in the Chandrapur area, in central India,
752 km away. The HVDC link stabilizes the Maharashtra grid, increases the power flow on the existing East-West 400 kV AC-lines and minimizes the total line losses.

The power to be evacuated from the Chandrapur 400 kV Bus is around 2700 MW. The AC transmission network, comprising three 400 kV circuits between Chandrapur and Mumbai, can safely transmit around 1200 MW of power without taking into account any contingency outage. It was therefore necessary to provide an additional transmission capacity of around 1500 MW. The HVDC transmission was commissioned in 1999.
