What Would Happen If the UK Lost Power? DEI Director, Simone Abram, Calls for Preparedness and Resilience

Recent global events, from large-scale blackouts in Europe to growing climate and geopolitical pressures, have prompted fresh discussion about how resilient modern energy systems really are. While the UK operates one of the most reliable electricity grids in the world, the reality remains that no system is entirely immune to disruption.

Energy systems are highly interconnected and carefully managed, but their complexity means that unexpected events can still occur. As Professor Abram notes in the feature, even well-designed systems can be vulnerable to rare, unforeseen triggers that set off wider failures. Rather than seeing blackouts as purely technical failures, this perspective emphasises the importance of understanding how interconnected systems behave under stress and how quickly disruption can escalate.

Events such as the widespread outage across Spain and Portugal illustrate how deeply electricity is embedded in everyday life. Transport networks stall, communications break down, and basic services become difficult to access - all within a short space of time.

These incidents also demonstrate that resilience is not just about preventing failure, but about how systems, and societies, respond when disruption does occur. This is a key focus of research at the Durham Energy Institute , where interdisciplinary approaches bring together technical expertise with insights into policy, behaviour and society.

One of the most significant challenges during a large-scale outage is maintaining clear and trusted communication. In a world where people expect instant updates, sudden information gaps can quickly lead to uncertainty.

Professor Abram’s contribution to the iNews feature highlights how a lack of clear information can increase anxiety and create space for misinformation. In such situations, maintaining public trust becomes just as important as restoring power. At the same time, research suggests that communities often respond positively in times of disruption, with people supporting each other and adapting to challenging circumstances, particularly where there is strong social cohesion.

While energy providers and policymakers continue to strengthen the UK’s infrastructure, there is growing recognition that resilience also depends on preparedness at a local and household level. Experiences from countries such as Norway show that a stronger culture of everyday preparedness, such as keeping basic supplies and having access to alternative sources of information, can make a significant difference during outages.

Simple steps, including having a torch, spare batteries, a battery-powered radio and essential supplies, can help households stay safe and informed while systems are restored.

As the UK transitions towards a lower-carbon energy system, incorporating renewable technologies and increased electrification, ensuring resilience remains a key priority. These changes bring long-term benefits but also introduce new complexities that must be carefully managed.

At Durham Energy Institute, research continues to explore how technical innovation, policy development and societal engagement can work together to strengthen energy security. Contributions to national media discussions form part of a wider effort to inform public understanding and support evidence-based decision-making.

Although large-scale blackouts are rare, the possibility highlights the importance of being prepared and informed. Building resilience is not solely the responsibility of infrastructure providers; it is a shared effort that includes communities, households and individuals.
