ERIA and IEEJ Strengthen Regional Energy Modelling for Energy Outlook 2027
Jakarta, 21–23 October 2026: ERIA and the Institute of Energy Economics, Japan (IEEJ), held the second working group meeting for ERIA Energy Outlook 2027, alongside practical training in Microfit and the Low Emissions Analysis Platform (LEAP). The activities were conducted in a hybrid format, bringing together representatives from Brunei Darussalam, Indonesia, the Lao People’s Democratic Republic (Lao PDR), Malaysia, the Republic of the Union of Myanmar, the Philippines, Singapore, Timor-Leste, and Viet Nam.
On 21 October, energy expert Ms Cecilya Malik led hands-on training on using Microfit for energy demand regression and LEAP for energy system modelling. The training aimed to strengthen the capacity of ASEAN Member States in energy modelling and system analysis. Participants included representatives from Lao PDR, Myanmar, the Philippines, and Timor-Leste.
The working group meeting opened on 22 October with remarks from Dr Han Phoumin, ERIA Senior Energy Economist and Working Group Leader. He outlined the agenda, provided updates on ERIA Energy Outlook 2027, and introduced new working group members.
The first session examined the impact of disruptions to the Strait of Hormuz. Mr Kentaro Noma, ERIA Programme Manager for Energy, discussed the observed impacts, followed by Dr Phoumin’s introduction to ERIA’s study on ASEAN oil stockpiling strategies. Dr Alloysius Joko Purwanto, ERIA Senior Energy Economist, then presented an analysis of Indonesia’s oil stockpiling roadmap.
The second session featured country presentations on national energy conditions and future projections for ERIA Energy Outlook 2027. Working group members also shared progress in developing business-as-usual scenarios and updates on the Strait of Hormuz situation, including its impacts and related policy measures.
On 23 October, ERIA Research Associates Mr Ryan Wiratama Bhaskara, Ms Laksmita Dwi Hersaputri, and Ms Shafa Nabilla Haya presented approaches to improving energy modelling methodologies, drawing on benchmarks from the International Energy Agency (IEA), IEEJ, and the ASEAN Centre for Energy (ACE).
The session continued with case studies on cost optimisation methodologies. Mr Muhammad Ilham Rizaldi and Mr Lazuwardi Imani of ACE presented the approach used in the ASEAN Energy Outlook, while Mr Soichi Morimoto, IEEJ Senior Researcher, explained the IEEJ-NE ASEAN modelling workflow.
In the final session, Mr Noma led discussions on the next steps for scenario design, modelling approaches, and data requirements. Dr Phoumin then delivered the meeting summary and closing remarks.
A follow-up training session, also led by Ms Malik, further strengthened working group members’ practical skills in using Microfit and LEAP.
Building on the discussions and training, working group members will update the model’s base year, conduct regression analysis and LEAP modelling, and incorporate future projections aligned with their respective national plans.
