India must act immediately to build climate resilience into its 267 GW renewable energy pipeline, as 90% of planned sites face high or critical physical climate risk by 2030, according to a new report by Zurich Group.
Critical Risk Assessment of 871 Sites
The analysis covered 871 sites across ten Indian states, with a combined planned capacity of about 267 GW. The report found that 66% of these sites are rated critical by 2030. Zurich emphasized that this is not a reason for alarm but a reason to act now, while many assets are still in planning or construction, allowing resilience to be built in at the lowest cost.
Solar Dominates the Pipeline
Solar energy accounts for 593 sites and 182,286 MW, nearly 70% of total assessed capacity. Wind comprises 230 sites and 44,177 MW. Hydropower, though only 48 sites, contributes 40,188 MW and carries disproportionately high financial exposure due to the capital intensity of civil infrastructure.
Key Hazards Identified
Zurich identified tornadoes, wildfires, floods, and hail as the main hazards. For solar projects, hail creates both direct visible damage—shattering glass layers—and hidden defects that degrade performance over time, only appearing later through reduced output. Wind projects face extreme wind events, flooding, and the consequences of intensifying monsoon and cyclone patterns. Hydropower increasingly depends on recognizing that historical hydrology is a weak guide to future performance.
Five-Step Resilience Framework
The report outlines five steps: make climate risk screening mandatory at the planning stage, stress-test the highest-risk assets first, build hazard-specific resilience into procurement, treat system resilience as part of asset resilience, and use resilience quantification to unlock capital.
Cost-Effective Resilience Investment
Zurich estimated that an indicative resilience investment of around 2% of CAPEX could reduce severe-loss exposure by as much as 75%, corresponding to an avoided-loss multiple of approximately 38x. A case study of a 2.5 GW solar project showed that without resilience measures, Value at Risk was approximately USD 178.5 million, but with a hail-storm tracker, the loss was reduced to USD 43 million. The incremental cost was about USD 34 million, or a 30% increase relative to a fixed-tilt system.
Resilience as an Enabler
"Resilience, embedded at the design stage, is not an additional cost. It is a practical enabler of bankable, insurable and sustainable energy infrastructure," Zurich said in the report.
