Summary
The electric power transmission system plays a strategic role in integrating generation centers and consumption hubs in Brazil, particularly during a period of expansion driven by the energy transition and the growth of renewable energy sources. This progress, however, occurs within a context marked by the intensification of climate change and the increasing frequency and severity of extreme events, which have made transmission lines (TLs) progressively more vulnerable.

– Pirapora 2 transmission line, which crosses the states of Bahia, Goiás, and Minas Gerais, all located in Brazil. The line has experienced recurrent damage associated with intense rainfall, lightning strikes, strong winds, and wildfires. Over its ten years of operation, the observed climate-related impacts highlight the growing challenges faced by the transmission sector and emphasize the urgent need to reassess and strengthen mitigation and adaptation strategies.
Based on this case study, key environmental factors influencing the observed damage are identified, including soil degradation caused by concentrated precipitation, increased lightning incidence, abrupt wind variations, and prolonged drought periods. The paper also examines the solutions implemented to enhance the structural and operational resilience of the transmission infrastructure.
