Energy Grid Resilience

Alison Bennett Excerpts

Wednesday 30th April 2025 Commons Chamber

[Michael Shanks]

Madam Deputy Speaker, I think you need to make a ruling on drawing marathon-related puns in the House to an end, but the subject is a really important one. Of course, that is why we are in this sprint towards building more network infrastructure—[Interruption.] Thank you.

There are two really important things to recognise with our network. First, it cannot stay in the state that it is in forever; it needs upgrading. Secondly, the demand that we fully expect to see—potentially a doubling by 2050, and maybe even more than that—means that we will have to build more grid to bring the power to where it is necessary to deliver economic growth. It is right that we move forward with that, but everyone will need to recognise that, to deliver that system—whether we are delivering clean power or not—the network is necessary, and stuff does have to get built somewhere. The Government are committed to building it and the Conservative party is committed to opposing it.

Will the Minister expand a little on a question put to him by my hon. Friend the Member for Thornbury and Yate (Claire Young)? The PSTN, or public switched telephone network, switch-off means that by the end of 2027 all landlines will require an electricity supply. This means that the mobile network becomes ever more vital for people who require their mobile phones for medical care or even to make a 999 call in the event of an emergency. What assessment has been made of the resilience of the mobile network in the event of power outages? What more needs to be done to make sure we are ready for that kind of situation?

[Michael Shanks]

I thank the hon. Lady for that important question. I was here after Storm Éowyn, when we discussed that a number of people who no longer had a copper wire line were not able to contact emergency services. It was a really important point.

There is resilience built into the mobile phone network to ensure that masts should be able to operate in circumstances when even the power to them is cut off. It is a question for Ofcom to look at and I have spoken to my colleagues in the Department for Science, Innovation and Technology and the Department for Culture, Media and Sport to make sure that that is happening. There is more that we can do. We are engaging with the Energy Networks Association, which works with distribution network operators, to make sure that all the resilience plans join up and that the practical impact that the hon. Lady rightly raises is taken into account. I will write to her with updates.
