Impact and Strategies in Response to Climate Change and Extreme Weather Events on EHV Transmission Lines

The global power transmission sector is facing unprecedented challenges due to accelerating impacts of climate change, reflected in increasing frequency and intensity of extreme weather events such as cyclones, severe storms, prolonged heatwaves, wildfires, icing events and large-scale flooding.[9][10] These events impose complex mechanical, thermal and environmental stresses on Extra High Voltage (EHV) transmission infrastructure, compromising tower stability, conductor performance, insulation reliability and foundation integrity, and directly affecting power system reliability.[1][2][9] by Indian powergrid, spans highly diverse climatic zones including cyclone-prone coastlines, flood-dominated river basins, snowbound
