本論文は、エネルギートランジションにおいて、予期せぬ事象に対してもロバストな初期段階の意思決定を特定する枠組みを提案する。ベルギーを対象としたエネルギーシステムモデルを用い、コスト最適解より最大10%高い代替経路を生成し、マルチアームドバンディットによりロバストな選択肢を抽出。結果、多様な発電ポートフォリオと早期の電動化・e-fuel輸入が重要と示した。
English
This paper proposes a framework to identify robust early-stage decisions in energy transitions under unexpected events. Using a whole-energy system model for Belgium, it generates near-optimal pathways up to 10% costlier than the optimum and applies Multi-Armed Bandits to find robust choices. Results highlight the need for a diverse generation portfolio, early BEV adoption, and e-fuel imports for robustness.

📄 Abstract（原文）
Although rare, unexpected events such as financial crises, geopolitical conflicts, and pandemics have reshaped reality in recent years. Despite their strong potential to affect the energy transition, such events are still largely overlooked in energy planning studies. Ignoring them can lead to poorly informed decisions that may jeopardize the transition. Identifying early-stage decisions that remain robust under unexpected events is therefore essential. To address this challenge, EnergyScope Pathway, a whole-energy system model with limited foresight, is applied to Belgium. To increase the likelihood of a successful transition, the Modeling to Generate Alternatives approach is used to diversify early-stage decisions in 2035. These alternatives are allowed to be up to 10% more expensive than the cost-optimal solution. However, the large number of alternative designs is difficult to navigate for decision makers. To address this, a decision-support framework based on the Multi-Armed Bandit framework is used to identify early-stage decisions that are most robust to future unexpected events. In this step, the remaining transition phases are optimized under unexpected events sampled within predefined impact ranges. The results show that, under normal conditions, there is a high degree of flexibility in the decision space for the 2030–2035 phase, with many technologies or resources that can be entirely omitted. However, robust early-stage decisions rely on a diverse energy generation portfolio, with a stronger emphasis on wind deployment, early mobility shifts toward battery electric vehicles, and the import of e-fuels. These insights can help decision makers steer the energy transition toward a robust path from the beginning. While Belgium is used as a case study, this framework is transferable to other contexts.
