Mr Paul Kohler

I thank the Secretary of State for advance sight of her statement. I echo her words and those of others in expressing my gratitude to the firefighters and other emergency workers who fought the fire and to the airport, airline and other staff for all their hard work in the face of this catastrophic systems failure. What has happened is clearly a rare occurrence, but it raises a number of significant questions about the security and management of our critical national infrastructure. While I am pleased to hear that no foul play is currently suspected, the event has revealed vulnerabilities in our national security that may be exploited in future by terrorists and hostile state actors. It is consequently vital that lessons are learned to ensure that an incident like this does not happen again, and I welcome the announcement of a full investigation. It is deeply concerning that the failure of a single piece of infrastructure has taken down the entire airport. Heathrow is connected to three substations, and while two were impacted, the third was running and had enough capacity—thought to be around 72 MW—to power the whole of Heathrow, which requires a little more than 40 MW. It is evident that Heathrow’s power set-up could not be swiftly reconfigured to allow the third substation to be used. We need to understand why that was, and whether it could be remedied in future. While Heathrow claims that it is normal for airports not to have sufficient back-up capacity to power all of their needs, other industries that require even more power than Heathrow—such as data centres—take more robust steps to ensure they have sufficient back-up systems to counter such failures. Should our key international transport hub not have the same safeguards? We must also not forget those whose journeys were disrupted. It is estimated that over 200,000 passengers have been impacted by the event. However, under current regulations, most of those passengers will not be eligible for compensation. As such, I have three questions for the Secretary of State. First, what impact, if any, will this incident have on the Government’s plans for expansion at Heathrow? Can the national grid infrastructure cope with a third runway, or will the airport become more prone to failure? Secondly, does the Secretary of State believe that UK airports should be taking steps to increase their back-up capacity, in order to ensure that an incident like this does not happen again? Thirdly, does she believe that the current regulations around passenger compensation are sufficient?
