Nuclear Energy (Financing) Bill

Debate between Matthew Pennycook and Robert Goodwill

2nd reading
Wednesday 3rd November 2021 Commons Chamber

[Matthew Pennycook]

I listened carefully, as I always do, to what the hon. Gentleman said in his speech. I think what he misses is the fact that the demand for electricity will double, so I do not think that his argument about the amount of baseload or firm power that is required necessarily follows.

[Mr Goodwill]

Will the hon. Gentleman give way?

[Matthew Pennycook]

I will, but then I must make some progress.

[Mr Goodwill]

Does the hon. Gentleman also appreciate that we may need to generate large amounts of hydrogen, or indeed use nuclear energy for direct carbon capture, and perhaps synthesise jet fuel in that way?

[Matthew Pennycook]

I think we will need a range of technologies. Let me return to a point that has been made by several Members. I think we must take a lead from the Committee on Climate Change, which made its view very clear in its balanced pathway scenario for the sixth carbon budget. It estimates that we will need 10 GW of nuclear power by 2035. We will have a predominantly renewable energy system, but we do need the firm power that comes from a limited degree of nuclear to support that.

My second point relates to what has been the elephant in the room today, namely China’s involvement in UK nuclear power. As we debate the principle of the Bill today and scrutinise its provisions in the weeks to come, that issue cannot be set aside. Members in all parts of the House want to understand more fully precisely where the Government now stand on the deeply flawed deal that they struck with China General Nuclear in relation to Sizewell, which has been mentioned several times in the debate.

The CGN stake in Sizewell was without doubt a sweetener for the far larger prize of unfettered Chinese ownership and operation of a nuclear plant at Bradwell, but while it seems certain that the very notion of a Chinese-run UK nuclear plant is now dead, we have yet to hear Ministers say so explicitly, or tell the House how the Government intend to disentangle themselves from the 2016 investment agreement signed by the then Secretary of State, the right hon. Member for Tunbridge Wells (Greg Clark). We deserve to be told, and I hope that the Minister will at least make some reference to that issue in his closing remarks. We also need to know how the Government plan to divest CGN of its minority stake in Sizewell C, and what the estimated impact of that divestment will be on the overall financing of the project, because that issue has very real implications for the mechanism that the Government have chosen to enable Sizewell to progress, namely the RAB model.

That brings me to my third and final point. A number of Members, including the hon. Members for South Cambridgeshire (Anthony Browne) and the right hon. Member for Kingswood spoke clearly and forcefully about the advantages of the RAB model. It is not in dispute that the proposed model will lower the cost of capital on nuclear projects—I fully accept that—and it is also not in dispute that it would lower overall costs, although Labour Members take issue with the frankly heroic assumptions that underpin the claimed £30 billion to £80 billion in long-term savings vis-à-vis coal-fired financed projects. However, it is also undeniably the case that these advantages would be secured as a result of shifting a proportion of risk on to consumers.

It is worth emphasising not only that the RAB for which the Bill would provide, and the risk therefore entailed in it, are of a different order of magnitude from RAB arrangements utilised on other infrastructure projects, but also that when it comes to the yearly surcharges levied on customers on those projects financed via RAB arrangements—for example, the Thames tideway tunnel, which has been mentioned

several times today—there is an inherent degree of uncertainty about the level at which those charges might peak. That is why it is important that the right hon. Members for Vale of Glamorgan (Alun Cairns) and for Clwyd West (Mr Jones) and the hon. Member for Waveney (Peter Aldous) rightly emphasised the need to scrutinise the precise arrangements that will be brought forward and the need for safeguards when doing so.

While we on this side of the House acknowledge the advantages of the RAB model for new nuclear compared with contracts for difference financing, we have concerns about the potential exposure of customers if costs rise significantly or if serious overruns take place. We do not oppose the principle of the Bill, and we have no intention of voting against it this evening, but we intend to look very carefully in Committee at precisely how the Government intend to implement the RAB model in question, at whether its benefits are as significant as has been claimed, and at how many investors the Government expect to return to the UK market if this legislation passes. Most importantly, we want to work with the Government to explore ways in which consumers might be better protected from escalating costs in the event that things go wrong. New nuclear must provide secure and affordable low-carbon energy, but it is still by no means clear that the Bill stands to deliver in both those respects. It is imperative that it should do so.
