As part of the development process for the 9th ASEAN Energy Outlook (AEO9), the ASEAN Centre for Energy (ACE) conducted a country visit to Singapore on 2 March 2026 in Energy Market Authority of Singapore. This visit is part of a broader series of in-depth consultations being carried out across all eleven ASEAN Member States between January and March 2025, with the aim of refining modelling inputs, validating assumptions, and fostering closer alignment between national priorities and regional energy analysis. The AEO9 Country Visits are supported by the UK Foreign, Commonwealth & Development Office (FCDO) through the ASEAN-UK Green Transition Fund (GTF).

The session continued with remarks from ACE, followed by a technical presentation by Yudiandra Yuwono, Senior Energy Modeller at ACE, who delivered an AEO9 progress update. He went through the AEO9 development timeline and modelling framework, underscoring the vital role of high-quality national data in improving the accuracy and relevance of the projections. The presentation also highlighted the country's visits as a crucial milestone in building strong national ownership of the AEO9 outcomes.

Subsequently, Silvira Ayu Rosalia, Energy Statistician of MPP at ACE, alongside Fadel Maulana, Data Officer of MPP, facilitated a comprehensive consultation on data inputs and modelling assumptions, covering socio-economic indicators, policy frameworks, energy balance tables, sectoral energy demand, and supply and transformation data. The session was aimed at validating existing datasets, clarifying methodological and assumptions approaches, and identifying any data gaps or areas requiring revision. It also promoted cross-sectoral dialogue among representatives from energy agencies, utilities, and other relevant institutions, helping to ensure that well-rounded and consistent national inputs are delivered to AEO9.
Continuing the technical session, Muhammad Ilham Rizaldi, Energy Modeller of MPP at ACE, presented the preliminary findings of the Baseline Scenario (BAS) and the AMS Target Scenario (ATS) for Singapore. The session provided national stakeholders with the opportunity to examine initial projections on energy demand, supply, and transformation, while deliberating on how existing and planned policies are captured in the modelling. Participants offered their perspectives on sectoral trends, technology uptake, and policy implementation timelines, helping to ensure that the country-level results more precisely reflect Singapore’s energy landscape.

The subsequent session focused on the Regional Aspiration Scenario (RAS), presented by Yudiandra Yuwono, Senior Energy Modeller at ACE, who outlined the proposed definition and modelling approach for a more ambitious regional pathway in line with ASEAN's long-term decarbonisation and sustainability goals. Through an interactive discussion, Singapore’s representatives identified potential policy levers, technology options, and areas for intervention that could elevate ambition levels, with the insights gathered set to inform the calibration of the RAS and reinforce its relevance to national contexts. This was immediately followed by Rhea Oktaqiara, Research Associate of MPP at ACE, who presented the ASEAN Energy Investment 2025 report with its complementing roadmap, while sought data inputs from ASEAN Member States for the 2026 edition.

The visit wrapped up with a Way Forward and Closing session led by a representative of ACE, who expressed appreciation to Singapore’s focal points and participating institutions for their active engagement and meaningful technical contributions, emphasizing that the feedback received would directly shape the refinement of country-level results and the design of the RAS. ACE also outlined the next steps in the AEO9 process, underscoring upcoming technical engagements and continued coordination with AMS to uphold transparency and foster shared ownership of the final outputs. The visit also went beyond data validation, serving as a platform for knowledge exchange on scenario development, energy planning, and inclusive transition pathways, reaffirming ASEAN's collective dedication to a secure, resilient, and sustainable energy future.
