Net Zero Transition: Consumer-led Flexibility

Julie Minns Excerpts

Tuesday 9th December 2025 Westminster Hall

[Martin Wrigley (Newton Abbot) (LD)]

It is a pleasure to serve under your chairmanship, Mr Vickers. My hon. Friend the Member for Thornbury and Yate (Claire Young) has made the case extremely well. I think I have heard unanimous opinion around the Chamber that we should not only do this, but do it now with some urgency. Flexibility first is the way to go. I will go one level further than the hon. Member for Strangford (Jim Shannon), who called this a “win-win”: I would call this a win-win-win. We can shave £1.3 billion off infrastructure costs through actions like this, which will be reflected in every single person’s bill. That is a massive win. It is also a win for producers because it is easier to balance production and consumption, and it is a win for individual consumers who will reduce their individual prices. It is three wins in one. Why would we not want to do that?

I absolutely agree with the hon. Member for Leeds Central and Headingley (Alex Sobel)—we should have done this yesterday. The best time to plant a tree was 10 years ago; the second best time is now. We are at the point of the second best time, but let us use this time and make sure that it happens. I join my hon. Friend the Member for Thornbury and Yate in pushing the Government to take action urgently.

When preparing for this debate, I remembered a geography school trip I went on where we looked at last-century solutions for balancing the grid. We went to visit Dinorwig, which is a pumped storage system—or was; I am not sure it is still going—in the hills in Wales. During the night, it pumps the water from the lake at the bottom of the hill up into a corrie at the top—aptly, as it turns out. As was quoted in the ad break in the middle of “Coronation Street”, when people switched on their kettles and created a power surge, that system could switch on in 30 seconds and provide significant amounts of power into the grid. It was a very good solution, but it is last century’s solution. What we need is an information-based solution, an individually empowering solution, such as we are talking about here, with consumer flexibility coming first.

[Ms Julie Minns (Carlisle) (Lab)]

The hon. Member makes a point about a modern solution. I have felt for some time that our supermarkets, with the installation of bi-directional chargers, could offer consumers the opportunity to bring their mobile energy source—their EV—as a power supply during peak times for supermarkets; in return, consumers could be offered a discount on their shopping for that hour. When the Minister makes his comments, I would welcome his thoughts on whether we need to go further with bi-directional chargers in supermarkets.

[Martin Wrigley]

That had not occurred to me, but it is an amazing idea; people taking their mobile power source with them—fantastic.

That brings me on to other solutions that we should be looking at, particularly community energy generation, community networks and community power consortia, as well as business inclusion—businesses that can generate more electricity during the day than they are using. We should be encouraging those things to happen, moving away from the centralised model of the past and towards the distributed and inclusive model of the future.

While flexibility is an excellent step, it will obviously not solve all the issues. We still need to fundamentally change energy generation contracts to de-link the cost of electricity from the price of gas. That will need to be done as well, but all these things are largely contractual issues, not technical ones. We do not need to reinvent something humongously different; we simply need to get the contracts right and change the energy market. I say “simply”—I understand that these changes have their complexities, but they are achievable. We know what we need to do.

The other massive energy issue is home insulation, which must not be forgotten. It is the single most important thing we need to do to reduce our fuel usage. The district council that I led demonstrated that very well—I draw hon. Members attention to my entry in the Register of Members’ Financial Interests, which notes that I am still a councillor on Teignbridge district council—when it started building council houses for the first time in 30 years. The first pair of semi-detached houses that we built are well insulated, with solar panels on the roof and air source heat pumps. At the height of the gas price crisis, the power bill for that home was just £500. We can do that with modern insulation and modern efficiencies.

Flexibility is one extra piece that we need to further reduce the cost. It is all part of a journey, and we are going in the right direction. I urge the Government to take faster action and to do everything they can to make it happen. As we have heard, industry is already looking for it. Let us make it happen.
