The Ministry Of Energy And Mineral Resources Encourages The Realization Of A "super Grid" Through HVDC Technology

The Ministry of Energy and Mineral Resources (ESDM) is promoting the development of inter-island electricity transmission networks through High Voltage Direct Current (HVDC) technology, as a strategic effort to realize the Indonesia Super Grid project.

"To achieve the Indonesia Super Grid, further collaboration is required between local and international partners in developing policy frameworks, efficient transmission, green financing, and public engagement," stated the Coordinator of Electric Power Transmission Planning, Muhadi, as quoted from the official website of the Directorate General of Electricity of the ESDM Ministry, Jakarta, on Wednesday.

One of the priority projects currently being prepared by the government is the Interconnection of Sumatra and Java (ISJ).

This project aims to transmit renewable energy potential from Sumatra to the main consumption center on Java Island. HVDC technology, whether through overhead lines or underwater cables, has been identified as the most feasible technical solution for this project.

Additionally, the development of a 500 kV High Voltage Alternating Current (HVAC) transmission network is also underway in Sumatra. Meanwhile, in Kalimantan, the energy potential of 13 GW from the Hydroelectric Power Plants (PLTA) on the Kayan and Mentarang Rivers requires a large-scale transmission network to Java and to support the smelter industry needs in Sulawesi.

The implementation of HVDC technology in Indonesia is considered capable of accelerating the integration of smart grids and supporting the penetration of renewable energy, particularly Variable Renewable Energy (VRE), as part of the national energy transition agenda.

Previously, the Minister of Energy and Mineral Resources (ESDM), Bahlil Lahadalia, revealed that the construction of electricity transmission over the next decade will reach a total of 47,758 circuit kilometers (kms).

This network will connect renewable energy power plants to PLN substations, subsequently distributing power to the distribution network until it reaches customers or end users.

Among the total transmission planned for construction, the regions of Java, Madura, and Bali will have the longest stretch, totaling 13.9 thousand kms. Additionally, 11.2 thousand kms will be constructed in Sumatra, 9.8 thousand kms in Kalimantan, and 9 thousand kms in Sulawesi.

Furthermore, Bahlil continued, to strengthen the electricity system in Eastern Indonesia, there will also be an addition of transmission spanning 3.9 thousand kms in the Maluku, Papua, and Nusa Tenggara regions.
