The UK’s electricity grid has developed over 140 years, now shifting from fossil fuels to clean energy, which requires significant infrastructure upgrades to meet rising demand and ensure secure delivery across a highly connected landscape. This presentation focuses on the real-world vulnerabilities of the UK’s energy infrastructure, including both physical and cyber threats, without relying on speculation or media-driven narratives. It will explore key components of the energy network, examine past and present attacks, and efforts being made to strengthen and secure the our national infrastructure.
