A report by Ember emphasizes the importance of expanding renewable energy and strengthening grids in Southeast Asia to enhance power system resilience. Examples from Indonesia, the Philippines, and Viet Nam showcase the benefits of distributed renewables in offsetting fossil fuel capacity, improving disaster recovery, and reducing costs related to solar curtailment. The report underscores the need for renewable energy and grid upgrades to be central to policymaking in the region, while also highlighting the significance of investments in renewables, storage, and grid interconnection for building power systems that can withstand climate risks and disruptions. Practical guidance is provided for ASEAN governments to protect energy security and promote a more resilient clean energy future.
