Overview
- The unidentified small-scale generator was taken offline for four days last month, and staff worked to restore operations while officials kept the site location secret for security reasons.
- UK ministers and the Department for Energy Security and Net Zero said the outage never risked Britain’s overall electricity supply because the site was well below legal thresholds for critical generators.
- Reporting attributes the intrusion to hackers linked to the Iranian regime, and the episode coincided with US investigations into July attacks on water systems that US officials tied to Iran-affiliated actors.
- The National Cyber Security Centre was notified but declined to comment on the specific incident; the government briefed energy CEOs and sent firms guidance on next steps and resilience measures.
- Security officials point to a wider rise in state-linked activity, the NCSC’s handling of hundreds of infrastructure attacks last year, and concerns that tools such as AI can speed and lower the cost of such operations.
