The Increasingly Critical Role of Communication Networks in Enhancing Power Grid Resilience Under Climate Change

The increasing frequency and severity of extreme weather events, driven by climate change, pose significant challenges to the resilience of power grids worldwide. As critical infrastructure, power grids must adapt to these disruptions while meeting the growing demands of renewable energy integration, distributed energy resources (DERs), and energy system electrification. This position paper highlights the important role of communication networks in enhancing power grid resilience and the integration of renewable energy resources. Advanced communication technologies, such as 5G, IoT, and AI-driven analytics, enable real-time monitoring, fault detection, demand forecasting, and resource optimization, all of which are crucial for grid reliability under dynamic and extreme conditions. The paper analyses the vulnerability of electricity grids to climate-related disruptions, examines technical solutions to these challenges and provides strategic recommendations for the design of robust com munication infrastructures. With a focus on redundancy, supporting technologies such as 5G and AI-powered analytics and decision support, this paper makes the argument for prioritising investment in resilient communication systems to future-proof power grids. By presenting communication networks as an essential part of grid modernisation, this paper underlines their crucial role in ensuring reliable, efficient and adaptable energy systems in the face of climate change.
