Operational Challenges Faced by Distribution Utilities in the Era of Climate Change

This paper explores the operational challenges faced by electricity distribution utilities in the context of climate change. Due to climate change, distribution utilities encounter severe damages and interruptions to their infrastructure and services' reliability due to the increase in the frequency and intensity of extreme and adverse weather events, rising temperatures, and shifting rainfall patterns. Globally, key challenges include damage from storms and floods, increased strain on equipment during heatwaves, and the threat of wildfires. Additionally, the integration of intermittent and weather dependent renewable energy sources as well as the compliance with evolving regulatory requirements adds complexity to utility operations under adverse weather conditions. To address these issues, utilities must invest in resilient infrastructure, adopt advanced monitoring and control systems, and implement strategic planning and sustainability practices. By understanding and mitigating these challenges, distribution utilities can enhance their resilience and continue to provide reliable service in increasingly unpredictable climate events. The paper illustrates the challenges faced by AADC during the last adverse weather conditions that had the highest amount of rainfall in 75 years and the extremely hot temperatures reached in the last few summers.
