Heathrow Substation Outage: NESO Review

Contribution

I, too, thank the Minister for making this statement, and NESO for this damning report. Heathrow Airport Ltd’s power set-up internally virtually guarantees hours of disruption in a scenario like this. On 21 March, that meant over a quarter of a million passengers were affected; airlines lost significant revenue, for which they will not be compensated; and countless time-critical freight loads were also affected. Yet in Spain and Portugal, airports did not close when those countries had full power outages. By any definition, surely Heathrow airport counts as critical national infrastructure as it undeniably requires operational continuity. I note that the Minister confirmed the airport’s responsibility for its own power resilience, but does the Government have a role in ensuring that end-to-end power supply to critical national infrastructure is robust and that risks like power outages are managed adequately?
