Key Takeaways
- 64% of ASEAN’s power generation capacity relies on fossil fuels, making the region vulnerable to climate challenges.
- Distributed renewable energy systems can enhance resilience against climate stress and natural disasters.
- Investment in stronger grids and energy storage is crucial for an effective energy transition in Southeast Asia.
Distributed Renewable Energy Enhances Resilience in Southeast Asia
A new report by Ember, a global energy think tank, reveals that combining solar, wind, battery storage, and enhanced grid connections can significantly improve the resilience of power systems in Southeast Asia, compared to traditional fossil fuel-based networks.
Currently, 64% of power generation capacity in the ASEAN region comes from fossil fuels, leaving electricity systems vulnerable to disruptions caused by climate change and natural disasters. The report argues that decentralized renewable energy networks are more adept at withstanding both chronic climate stress and sudden disasters. They can isolate damaged assets and enable faster restoration of electricity supplies.
Under extreme climate scenarios projected for 2030, wind and solar energy sources are expected to show less than 1% output variability. This is significantly less than the expected generation losses from thermal and nuclear plants that may face even milder climate conditions.
The report identifies two critical challenges for ASEAN’s electricity sector: chronic climate stress, which gradually affects generation performance, and acute natural disasters that can damage infrastructure. Decentralized renewable systems offer inherent advantages, allowing localized repairs without disrupting the overall electricity network.
The report includes country-specific examples to showcase the benefits of distributed renewable energy systems. In Indonesia, the 2018 earthquake disrupted coal power availability, damaging extensive infrastructure. Ember suggests that deploying solar and battery solutions could replace a significant portion of coal capacity and expedite recovery.
In the Philippines, repeated typhoons have led to prolonged outages due to overreliance on diesel generators. The planned interconnection with Luzon aims to fulfill up to 22% of Catanduanes Province’s electricity demand by 2030, thus improving overall grid resilience.
Similarly, Vietnam faces challenges related to limited transmission capabilities, resulting in significant economic losses due to solar curtailment. Recommendations for enhancing renewable energy utilization include expanding transmission infrastructure and increasing energy storage capacity.
Ember emphasizes the importance of integrating energy planning into broader disaster management initiatives. Increased investments in transmission interconnections, grid flexibility, and energy storage are essential for advancing distributed renewable systems.
Dr. Dinita Setyawati of Ember highlighted the need for renewable energy and robust grid systems to form a core part of ASEAN’s energy policies, enhancing energy security and supporting green economy goals.
Philippine Undersecretary Felix William B. Fuentebella added that building power system resilience should remain central to the region’s energy transition, with a focus on renewable investments.
Brian Eyler from the Stimson Center noted that the report offers practical strategies for ASEAN nations to create more resilient electricity systems capable of enduring climate risks and facilitating the shift to clean energy.
