TransitionZero has launched a significant upgrade to its Scenario Builder platform, enabling comprehensive energy system modelling across the Association of Southeast Asian Nations (ASEAN). This enhancement allows for integrated analysis of power systems in 10 Southeast Asian countries, addressing the fragmented nature of the region’s cross-border electricity trade.
The ASEAN Power Grid, envisioned in the ASEAN Vision 2020, aims to create a regionally interconnected power system. However, progress has been limited and uneven. TransitionZero’s latest upgrade facilitates the testing of cross-border scenarios on a single interface, covering energy generation, transmission, and trade flows. This development eliminates the need for separate studies or fragmented national models, streamlining the planning process for energy planners.
Isabella Suarez, Head of Engagement for Southeast Asia at TransitionZero, highlighted the significance of this launch. She stated that it represents a step towards more informed cross-border planning, market design, and regional investment decisions. The upgrade is expected to reduce duplicated modelling efforts across the region, promoting efficiency and collaboration.
TransitionZero also offers insights from legal and policy experts on the necessity of robust regulatory frameworks to support a regionally interconnected power system. This initiative marks a pivotal moment in advancing Southeast Asia’s energy infrastructure, potentially transforming the way energy is managed and traded across borders.
