Enabling Indonesia's Energy Transition with HVDC

Indonesia is taking big steps to build a cleaner, more reliable energy system. One of the key projects is the Sumatra–Java interconnection, which will use High Voltage Direct Current (HVDC) technology to transmit electricity between islands. This project is part of the government’s recently launched 2025–2034 Electricity Supply Business Plan (RUPTL), which outlines a plan to build 48,000 kilometers of transmission lines to support renewable energy and improve access to power across the country. It’s also a major part of the Indonesia’s Green Enabling Supergrid program, aimed at strengthening national energy resilience.

To support this important initiative, we’ve been working closely with relevant key stakeholders through collaboration, partnership and knowledge sharing.

Following up on our MoU with PLN signed in 2023, we have conducted a series of activities to share our expertise in HVDC. Recent highlights was a seminar titled “Fundamentals of HVDC Transmission Technology”, where we invited Shanthakumar, HVDC Market Product Manager for South Asia & India, to lead a full day session hosted by PLN. The event opened with remarks from PLN’s Executive Vice President of Java-Sumatra Transmission, Eko Yudho, and our Country Managing Director Predrag Grupkovic. The session sparked active discussions and gave PLN teams a deeper understanding of how HVDC can support Indonesia’s future energy needs.

We also participated in a roundtable organized by Business Sweden, where our Country Managing Director, Predrag Grupkovic, spoke about our HVDC leadership and how our technology can help deliver efficient, long-distance power transmission across islands.

To take this collaboration further, we coordinated a visit to our HVDC Center in Ludvika, Sweden, organized by Business Sweden. The Indonesian delegation included PLN’s Director of Technology, Engineering & Sustainability, Evy Haryadi, along with representatives from the Ministry of Energy and Mineral Resources, LAPI ITB, Swedfund and Business Sweden.

These activities show our strong commitment to supporting Indonesia’s energy transition—not just with advanced technology, but through real partnerships, shared knowledge, and long-term collaboration.
