UK Electricity Distribution Networks Under Increased Threat from Extreme Weather Events
London, UK – August 1st, 2025 – The UK’s electricity distribution networks are facing a growing and significant risk from an escalating frequency and intensity of extreme weather events, according to a stark warning issued today by VisNet. The national infrastructure consultancy’s analysis highlights that a combination of heatwaves, storms, and other climate-related phenomena are placing unprecedented pressure on the systems responsible for delivering power to homes and businesses across the country.
Published by Electrical Times, the VisNet report, titled ‘Electricity distribution networks face increased risk from heatwaves, storms and other extreme weather, says VisNet’, outlines a concerning outlook for the resilience of the electricity grid. As the UK experiences more volatile weather patterns, the infrastructure that has historically served reliably is being pushed to its limits, creating potential vulnerabilities in power supply.
The report details how rising temperatures during prolonged heatwaves can lead to increased demand for electricity due to air conditioning use. Simultaneously, the elevated temperatures can also reduce the efficiency of electricity transmission and distribution equipment, such as transformers, making them more susceptible to overheating and failure. This dual impact creates a challenging scenario for network operators.
Furthermore, VisNet’s findings underscore the detrimental effects of increasingly severe storms. High winds can bring down power lines and poles, while heavy rainfall can lead to flooding, inundating substations and critical infrastructure. The report suggests that the intensity and frequency of these events are exceeding the original design parameters of many existing network components.
The analysis also extends to other climate-related impacts, such as drought conditions, which can affect the cooling systems of power generation facilities, and changes in precipitation patterns that can influence the performance of renewable energy sources connected to the distribution networks.
VisNet’s call to action emphasizes the urgent need for proactive investment and strategic planning to bolster the resilience of the UK’s electricity distribution networks. This includes upgrading aging infrastructure, implementing advanced monitoring and control technologies, and developing more robust emergency response and restoration capabilities. The report also suggests that a greater focus on distributed energy resources and smart grid technologies could play a vital role in enhancing the overall stability and flexibility of the system.
The implications of these findings are far-reaching, impacting not only the reliability of power supply but also the nation’s ability to meet its climate targets and ensure the smooth functioning of the economy and society. As the UK navigates the challenges of a changing climate, ensuring the robustness of its electricity distribution networks is paramount to securing a sustainable and resilient energy future.
