PT PLN (Indonesia) to complete 500 kV Sumatra – Java HVDC project by 2024

Indonesia’s state-owned power company PT Perusahaan Listrik Negara (PT PLN) is planning to complete the 500 kV high voltage direct current (HVDC) project to connect the two islands of Sumatra and Java by 2024. The project involves the construction of a ±500 kV HVDC transmission line from the Bangko Tengah converter/inverter station to the Ketapang connection point in the Sumatra area. From there, an undersea cable will run to Tanjung Salira in Java where it will be further extended to the X Bogor converter/inverter station in the West Java area. The project also involves the construction of the Bangko Tengah and X Bogor converter/inverter stations. The project was halted in 2016 as PT PLN observed that the project was not economically feasible as the Java region had enough generation capacity to meet its power demand. As per PT PLN’s Electricity Supply Business Plan (2017-26), the project will now be developed to meet the increasing power demand in the Sumatra region.
