Java-Sumatra HVDC Interconnection System

From Global Energy Monitor

The Java-Sumatra HVDC Interconnection System is a proposed 'High Voltage Direct Current' (HVDC) transmission connection from Sumatra, where major coal-fired power stations have been proposed, to the island of Java where major load centres are.

Japanese agency offers loan funding

In June 2014 the Japan International Cooperation Agency (JICA), the Japanese government’s international development agency, offered to loan US$1.19 billion of a US$2.1 billion high voltage cable to connect coal power plants in Sumatra with the main load centres in Java. The cable is proposed to cross a 35 kilometre-wide portion of the Sunda Strait. The Indonesian Minister of National Development Planning, Armida Alisjahbana, said that JICA could fund the entire cost of the project if approved by the Indonesian President.[1]

November 2016: Project placed on hold

on November 2, 2016, the Java-Sumatra HVDC Interconnection System was placed on hold for at least two years. This line would have supported the transfer of 3,000 MW of capacity from three mine-mouth plants in Banko Tengah. Due to the delay of the HDVC line, the Bangko Tengah (SS-8) project is currently shelved while new power purchase arrangements are developed.[2]
