Heathrow Substation Outage: NESO Review

Richard Tice Excerpts

Wednesday 2nd July 2025 Commons Chamber

[Michael Shanks]

I thank the right hon. Gentleman for his remarks and for the way he made them. He is absolutely right to recognise the heroic role that our emergency services played on the night—I am sorry that I did not say that at the start of my statement—as well as the engineers, who worked in incredibly hard in difficult circumstances in the hours that followed the fire to try to get services reconnected as quickly as possible. There are very serious questions to answer, and I hope that came through in my statement—it certainly came through in the conversation I had with National Grid earlier. We are seeking urgent assurances that the work that should have been done is being done, and that there are no other similar situations. Ofgem is taking the matter seriously, with two reviews, one into National Grid and the other into the wider energy system, to see if there are any further lessons to learn.

However, the right hon. Gentleman is right and I completely agree with his point that the Government need to be front-footed and take a leadership role in driving the work forward: we cannot leave it to individual companies to mark their own homework. We are doing that partly by bringing together our resilience work across Government, and I will soon be chairing a new group that brings together everyone who has responsibility for critical national infrastructure in our energy system, to ensure that energy security, cyber-security and other threats to our infrastructure are taken seriously, so that action is taken at the highest level of Government to ensure that we do not have a repeat of the incident in future.

The substation by Heathrow is probably one of the most important in the country, yet this damning report says that there was a “catastrophic failure” of maintenance. Given that National Grid also failed to recognise how close we came to a national blackout earlier this year, we have to ask: is National Grid grossly negligent and does the Minister still have full confidence in its management?

[Michael Shanks]

The hon. Gentleman may be confusing two things. The National Energy System Operator is no longer part of National Grid, as it was made into a publicly owned company by the previous Government, which was introduced by us when we came into Government. So the National Energy System Operator is responsible for managing the energy system and it is different from National Grid, which is a private company that operates the electricity network in England, so those two organisations are slightly different. Of course, he is right to highlight the scale of the failure. That is why I have given a statement today and why a number of serious actions are being taken, which will be followed up in a serious way.

We did not come close to a blackout earlier this year. It is important to repeat that, because there is a lot of misinformation about a particular set of statistics that were misunderstood by some people. We have never come close to that and we have never had a national power outage in our history. The aim of all the work that we do is to build as safe and resilient an electricity system as we can, so that when circumstances like this happen—because fires and accidents do happen—we will have done everything that we could have done to have mitigations in place. When such a fault is down to a failure of maintenance, we must ensure that is taken account of and never happens again.
