A recent study published in ‘iScience’ has unveiled a strategic roadmap for the Association of Southeast Asian Nations (ASEAN) to achieve a decarbonized power sector by 2050. The research, led by Sheng Zhong from the Energy Studies Institute at the National University of Singapore, highlights how cross-border transmission and renewable energy can significantly impact the region’s energy transition.
With the ASEAN countries facing ambitious energy transition objectives, the study employs an integrated power system capacity expansion model to explore various decarbonization pathways. The findings reveal that while transmission infrastructure represents a marginal share of overall costs—up to 0.5%—it can lead to a remarkable 11.9% reduction in cumulative system costs. This underscores the potential for cost-effective solutions in the transition to net-zero emissions.
“The investment requirements for a carbon-neutral power sector are substantial, amounting to 29.6%–44.6% of ASEAN’s 2018 GDP,” Zhong noted. This figure illustrates the economic scale of the challenge, yet it also emphasizes the opportunity for investment and growth within the energy sector. The uneven distribution of investment needs across member countries suggests that tailored strategies will be essential for each nation to meet its decarbonization goals.
The research identifies key technologies such as renewable energy sources, carbon capture and sequestration, and enhanced cross-border transmission capabilities as critical components in this transition. By strategically leveraging these technologies, ASEAN can not only reduce its carbon footprint but also enhance energy security and foster regional cooperation.
As Southeast Asia grapples with the dual pressures of energy demand and climate change, the implications of this study extend beyond environmental benefits. It presents a compelling case for investors and energy companies to engage in the region’s evolving landscape. The potential for reduced costs and increased efficiency could attract significant capital, driving innovation and job creation in the green energy sector.
Zhong’s insights shed light on the necessity of collaborative efforts among ASEAN nations to share resources and technologies. “A coordinated approach to energy transition can unlock new economic opportunities while ensuring sustainability,” he emphasized. This perspective is critical as the region strives to balance growth with environmental responsibility.
As ASEAN moves toward its net-zero targets, the findings from this study could serve as a pivotal guide for policymakers and stakeholders alike. By embracing a comprehensive and integrated approach to energy management, the region stands to not only meet its climate commitments but also enhance its economic resilience. The research serves as a clarion call for action, urging countries to invest in their energy futures while fostering collaboration across borders.
