On Oct 28th 2025, Albert Payaró-Llisterri and Georg Holzner travelled to Jakarta for a special event with our repowering partners in Repower Indonesia Initiatives and Institut Teknologi Bandung (ITB).
The illustrious occasion saw speeches, and panel discussions from stakeholders including representatives of the Director of PT PLN Nusantara Power, Dr. Agus Puji (a Member of the Indonesia National Energy Council – DEN), and representatives of the Tanjung Jati B coal-fired power plant.
“In the two years since we started our collaboration, the ITB-led repowering project has successfully demonstrated a pre-feasibility techno-economic study of repowering the Tanjung Jati B coal plant, and contributed to the concept of ‘repowering’ being included in Indonesia’s National Energy Policy (KEN) and the National Electricity Supply Business Plan (RUKN).” – Albert Payaró-Llisterri, Programme Manager of the Repower Initiative
⭐ ‘Repowering’ is now considered as ‘new energy and energy efficiency mitigations’ under Indonesia’s latest Nationally Determined Contribution (SNDC) submitted to the IPCC yesterday, ahead of COP30.
⭐ Dr. Agus Puji has proposed the formation of a ‘Repower National Task Force (Pokja)‘ in 2026, to coordinate policymakers, PLN, private partners, and academia for actionable programs and policy frameworks.
⭐ Nuclear-based repowering is now recognised and endorsed at the directorate level within PLN, and they are open to explore this further as part of Indonesia’s energy transition strategy.
⭐ The Tanjung Jati B coal boiler can be replaced by a Chinese High-Temperature Gas-cooled Reactor (HTGR), due to similar steam parameters. Brownfield conversion of existing coal plants could cut investment costs by up to 30% versus a greenfield nuclear plant.
Repower Indonesia Initiatives‘ next steps with the Government and PLN:
1️⃣ Mapping 60 GW of coal-fired capacity (including 40 GW under PLN), to identify which plants to repower, with what technology, and when.
2️⃣ Advancing pilot projects, both small and large-scale (e.g., Tanjung Jati B), as national replication models.
Repowering is a practical, financeable and scalable pathway to cleaner baseload power, utilising existing coal infrastructure.
Repower Initiative, Institut Teknologi Bandung and Repower Indonesia Initiatives are united in our verve to establish repowering as central to Indonesia’s clean energy transition.
