A June 2026 report from Zurich Resilience Solutions assessed 1,380 renewable energy generation sites across ten Southeast Asian countries and found that 927 of them, representing approximately 181,000 megawatts (MW) of capacity, fall into the highest climate risk categories under a 2030 scenario. That is 75% of the assessed pipeline, covering solar photovoltaic (PV), onshore wind, hydropower, and geothermal projects that are announced, planned, or under construction. The report notes the analysis is based on Zurich's proprietary climate risk modeling and the firm's commercial risk engineering work, and should be read with that context in mind.
The Association of Southeast Asian Nations (ASEAN) has set a target of 45% renewable installed power capacity by 2030, up from roughly 33% today. According to the report, reaching that target will require clean energy investment to reach approximately $190 billion annually by 2035, roughly five times current levels. The Philippines and Vietnam carry the largest combined exposure in the analysis, both because of the scale of their planned renewable pipelines and because renewables make up a significant share of each country's overall grid.
Solar Faces the Steepest Exposure; Hydropower Carries the Largest Value at Risk
Of the four technology types assessed, solar PV carries the steepest near-term risk profile. The report found 80% of all pipeline solar capacity falls into risk categories 4 or 5 by 2030, primarily driven by wind, hail, flooding, and wildfire exposure. Wind power fares better but not by much: 56% of planned wind capacity falls in the same high-risk categories, mainly from typhoon, flood, and coastal hazard exposure. Hydropower accounts for a smaller number of planned assets but holds disproportionate financial exposure given the scale and capital intensity of civil infrastructure. Approximately 55% of planned hydropower capacity lands in categories 4 or 5, and hydropower carries the largest single value at risk figure, just over $82 billion, across the assessed portfolio. Geothermal shows the lowest concentration of critical-risk assets but remains vulnerable to localized flooding, slope instability, and disruption to distributed steam field infrastructure.
The Resilience Investment Case: $13 Billion In, $82 Billion Avoided
Zurich's analysis estimates total value at risk across the ASEAN portfolio at $165 billion in the absence of resilience measures, a figure the report frames as the estimated maximum loss under a severe scenario. The firm projects that an upfront investment of approximately $13 billion, roughly 2% of total asset value, could avoid more than $82 billion in losses, an indicated return of approximately 6.5x. Resilience measures typically add between 2% and 10% to capital expenditures when embedded at the design or construction stage. The report argues the timing is significant: most of the assessed assets are still in planning or construction, meaning design choices that determine long-term climate exposure have not yet been locked in. The Asian Development Bank (ADB) estimated annual climate adaptation investment needs across Asia at $102 to $431 billion against tracked adaptation finance in 2021 and 2022 of approximately $34 billion, a gap the Zurich report uses to frame how far below need current resilience spending sits.
