An analysis by global energy think tank Ember concludes that distributed renewable energy infrastructure provides significantly greater resilience to climate-related disruptions and natural disasters compared to centralized fossil fuel power systems across Southeast Asia. The region currently relies on fossil fuels for approximately 64% of installed power capacity, creating vulnerability in one of the world’s most disaster-prone regions.
According to Ember’s modeling, renewable energy paired with battery storage and enhanced grid interconnection can isolate damage during disasters and recover more quickly than conventional plants. Under the most severe weather scenarios projected for 2030, wind and solar generation would experience less than 1% variation from typical output levels, substantially outperforming the losses that thermal and nuclear facilities would sustain under comparable warming conditions.
The report identifies two primary challenges for regional power systems: chronic climate stress that gradually reduces output across multiple generation types, and acute disaster events that can damage infrastructure. Distributed renewable networks address both threats more effectively than centralized fossil fuel systems because localized damage can be contained and repaired without disrupting the entire network.
Ember highlights specific regional examples demonstrating the case for renewable expansion. In Indonesia’s Central Sulawesi province, where a 2018 earthquake disabled a coal plant, solar and battery storage could offset planned coal capacity while offering faster deployment and repair capabilities. In the Philippines, grid interconnection projects are improving recovery speed for typhoon-affected areas. Vietnam experienced substantial solar curtailment in 2020 due to grid limitations, a situation that upgraded transmission and storage infrastructure could address.
The report recommends integrated resilience planning that incorporates energy infrastructure into regional disaster management frameworks and invests in interconnection, grid flexibility, and storage capabilities. Regional officials have indicated support for deepening cooperation on renewable integration and grid modernization as part of Southeast Asia’s energy transition strategy.
