Assessing the Impact of Extreme Heat Events on Energy Demand and Power Grid Resilience

As climate change intensifies, the increasing frequency and severity of extreme heat events are significantly impacting energy infrastructure, critically challenging the resilience of power grids altering patterns of energy consumption. The Southern United States is becoming increasingly vulnerable to the impacts of extreme heat events, which have become a major factor affecting regional energy demand and the reliability of the power grid. This study integrates historical weather data, energy demand data, and power outage records, and climate projections to examine the impacts of these events on energy consumption across the Southern United States. Using advanced deep learning models, this study investigates both current and future scenarios to understand the relationship between extreme heat events, including heatwaves and shorter periods of intense heat, and their effects on energy consumption and power outages across the Southern United States. Our results show that extreme heat leads to increases in electricity consumption, mainly due to higher air conditioning use. These surges often push the power grid to its limits, leading to frequent outages and exposing critical vulnerabilities in the region’s energy infrastructure. By incorporating climate projections, we forecast that these challenges will intensify, with increasingly frequent and severe heat events likely to exacerbate grid instability and energy shortages in coming decades. This research highlights the urgent need for targeted strategies to enhance grid resilience, optimize energy management, and prepare for a future characterized by more extreme and frequent heat events. These findings provide critical insights for policymakers, energy planners, and utility companies, emphasizing the importance of proactive measures to protect regional energy security from the increased risk posed by climate-induced extreme heat.
