Pelindo, onshore power supply at Tanjung Priok

Port of Tanjung Priok, Jakarta, Indonesia2020 to present (commercial service launched September 2026)

Tanjung Priok in Jakarta is Indonesia's main port and is run by the state port company Pelindo. Indonesia's Ministry of Transportation has made onshore power supply (OPS) a main policy for decarbonizing shipping. It links OPS to Minister of Transportation Regulation PM 50 of 2021 on seaport operation (ANTARA, 2022a). In 2022 the state utility PLN agreed with Pelindo to build 27 MVA of shore connection capacity at major Pelindo ports in Java, Kalimantan, NTT and NTB (ANTARA, 2022b).

Approach

Early low-voltage pilot. In 2020 the former Pelindo II (IPC) began a shore-to-ship facility at the domestic container berth in Tanjung Priok. It could supply both 50 Hz and 60 Hz ships (ANTARA, 2020).

Industry agreement. In October 2022 Pelindo's maritime services subholding signed a memorandum of understanding with the Indonesian National Shipowners' Association (INSA) on OPS use at Indonesian ports (ANTARA, 2022a).

Pilot berth with tests. A 500 kVA OPS facility was built at Berth 004 of the multipurpose Nusantara terminal. It passed a site acceptance test and was trialed on commercial ships in July 2026 (ANTARA, 2026).

Dedicated operator. Pelindo gave its subsidiary PT Energi Pelabuhan Indonesia (EPI) the job of running the service and the port's internal power network. PLN supplies the power (ANTARA, 2026).

Phased roadmap. Pelindo plans up to 24 OPS units at Tanjung Priok by 2027 and an indicative 123 units nationally by 2050 (ANTARA, 2026).

Results

Pelindo launched commercial OPS service at Berth 004 on 16 September 2026 (Pelindo, 2026; ANTARA, 2026). Based on testing, Pelindo estimates that OPS can cut ship exhaust emissions by up to 75 percent; this is an owner estimate of exhaust emissions at berth, not a measured lifecycle greenhouse gas reduction. ANTARA reports that measurements on two test ships showed possible energy cost savings of about 40 to 64 percent compared with ship generators, depending on engine and fuel type (ANTARA, 2026).

Transferability

DMC ports can start with a small pilot berth, test it on real ships, and then expand in phases. A clear national policy, an agreement with shipowners and a partnership with the power utility help build both demand and supply. Giving one entity responsibility for running the service and the port power network makes it easier to manage. Supplying both 50 Hz and 60 Hz ships increases the number of vessels that can connect.
