Indonesia’s state-owned power company, PT Perusahaan Listrik Negara (PT PLN), is planning to construct a subsea cable between Sumatra and Bangka. …
The subsea cable would be 36circuitkm in length and is expected to be completed by December 2021. Its cost is around IDR1.9 trillion (where IDR1= $0.000070).Electricity from Sumatra’s low-cost power plants can be piped to the island, thus reducing the generation cost in Banka as well as increasing the island’s electricity supply by about 109 MVA.
