Great British Energy Bill

Debate between Lord Hamilton of Epsom and Lord Wigley

Committee stage
Tuesday 3rd December 2024 Lords Chamber

[Lord Wigley (PC)]

My Lords, I will just intervene very briefly indeed in support of the noble Lord, Lord Ravensdale, with regard to Amendment 34 and the question of system reliability. In my previous incarnation I represented a constituency that had the Dinorwig pumped storage scheme. That scheme was brilliant in terms of being able to help guarantee the availability of electricity when it was needed. Half-time in the cup final was a traditional way of interpreting that, when there was a surge of demand. It had the capability of going from zero to full output in eight seconds.

The economic benefit of that is obvious in having a system that does not need to match the total maximum demand. The peaks of that graph are cut off and equalised in a way that makes a lower capacity, and therefore lower total capital investment, a viable proposition. The point I put to the Minister is this: a number of pumped storage schemes are being developed at the moment. There is a significant number in Scotland, including some of the larger ones, but they are also in Wales. They have been waiting for years to get the necessary information on which to base investment decisions. There is one using an old slate quarry hole in Talysarn in my former constituency. It is raring to go but, until it gets the details of the prices that will apply, it obviously cannot make an investment decision. We are talking about tens of millions of pounds, possibly hundreds of millions, and a benefit to the overall system.

In responding, can the Minister give any comfort by way of the timescale by when the framework for such decisions can be made? We really need to get on with it. I am quite sure that those in charge of Great British Energy will also need this information.

[Lord Hamilton of Epsom (Con)]

My Lords, I have always been a great supporter of small nuclear reactors, because it strikes me that they have the enormous advantage of supplying a locality and not getting involved, as the noble Earl, Lord Russell, said, with massive transmission costs. That would be all cut down, which has enormous advantage. Of course, Rolls-Royce is making small nuclear reactors to go into submarines, so we are probably better on the technology than most other people might be.

I have always had a worry that local people would react adversely to a planning application for a small nuclear reactor, because they would see it as devaluing their houses. Despite all-party support in Parliament, this will not stop local concerns raising their heads. I refer back to what the noble Earl, Lord Russell, said on that. I thought the answer was quite simply to offer people in the locality free electricity, and so immediately they would have an advantage. But from what the noble Lord, Lord Vaux, said when speaking to his amendment, that would not actually work. That is why I want to be absolutely clear about this. He seemed to say that wiring up all the local houses to the nuclear reactor—oh, he is shaking his head. Now I am confused. Could the noble Lord intervene and explain what he meant?
