The UK government has announced plans to introduce its first comprehensive Energy Resilience Strategy following the North Hyde substation fire in March, which caused widespread disruption at Heathrow Airport. The incident prompted immediate action, including commissioning the National Energy System Operator (NESO) to investigate the fire and assess Britain’s energy resilience. NESO’s investigation, concluded in July, found that the fire was likely caused by moisture in substation equipment leading to an electrical fault, and it provided 12 recommendations to reduce the risk and impact of similar incidents in the future.
The forthcoming Energy Resilience Strategy will set priorities for safeguarding critical energy infrastructure such as substations and cables against evolving risks, including climate change impacts, cyber threats, and geopolitical tensions. It will also provide guidance for government and industry collaboration to prevent disruptions, enhance preparedness, and ensure rapid response and recovery during incidents. The strategy aligns with HM Treasury’s 10-year infrastructure plan and the Cabinet Office’s Resilience Action Plan, reinforcing Britain’s commitment to maintaining high standards in energy resilience while supporting its clean energy ambitions.
The government is already implementing NESO’s recommendations, focusing on regular testing, maintenance, and upgrades to ageing infrastructure. Collaboration between energy operators, emergency services, and critical infrastructure sectors will be strengthened to ensure swift restoration of power during incidents. A new Energy Resilience and Security Taskforce, chaired by Energy Minister Michael Shanks and composed of energy sector CEOs, will oversee the delivery of these actions.
Key areas of focus include improving the resilience of energy infrastructure through better asset management, enhanced fire safety processes, and reviewing design standards for critical sites. Response and restoration capabilities will be reinforced by increasing coordination among energy operators and emergency services, while the resilience of essential services to energy disruption will be enhanced through improved continuity planning and cross-sector coordination.
NESO CEO Fintan Slye highlighted that while Great Britain already has one of the most reliable electricity systems in the world, the North Hyde review identified opportunities to strengthen it further. NESO will continue working with the government, industry, and critical infrastructure sites to build a more robust energy system capable of coping with future disruptions.
The Energy Resilience Strategy will also include proposals for risk prevention, preparedness, and recovery measures, ensuring that the UK’s energy system maintains the highest standards of resilience and security. In parallel, Ofgem has launched an enforcement investigation into National Grid Electricity Transmission and commissioned an independent audit of its critical assets to review compliance with maintenance and regulatory requirements.
