Electricity Market Review

Deirdre Costigan Excerpts

Thursday 10th July 2025 Commons Chamber

[Ed Miliband]

LDES, as it is known to the super-nerds—long-duration energy storage—is really important, as indeed are batteries. We now have a cap and floor mechanism for LDES. Ofgem, along with NESO, is looking at the applications that have been made, and that will now be driven forward. That is really important. What I always say to people is that we need all the elements of the system. We need nuclear—in my view—we need renewables, we need battery storage, and we also need LDES. All of them can contribute to a clean power system.

[Deirdre Costigan (Ealing Southall) (Lab)]

I thank the Secretary of State for his statement. It is clear that zonal pricing would not only waste valuable time in the race to reduce our reliance on costly fossil fuels; it would see my constituents in Ealing Southall, many of whom are on very low incomes, and indeed families across London paying more for their bills. Does he agree that this Labour Government’s plan to invest in clean, cheap, renewable energy and to reform energy pricing for the whole country as one is a fairer and more effective way of reducing bills for everyone?

[Ed Miliband]

I thank my hon. Friend for that really important question; she makes two points that are critical. One is the time it would take to get to a zonal pricing system, and the second is the arbitrary nature of who would benefit and how, and the cost differentials. I think we can see that there would be a great sense of unfairness about that. She is also absolutely right that the choice is not reform or no reform; the choice is: what kind of reform? That is what reformed national pricing is all about.

Above all—my hon. Friend the Member for Northampton South (Mike Reader) referred to this—this is about getting on with it. It might be lost in the mists of time, but the Conservatives used to have a target for clean power. It was for 95% clean power by 2030, but they never really talked about it much, and then they sort of abandoned it quietly. The truth is that they used to understand this. We have got to build the infrastructure and the renewable power generation.
