Commons ChamberI am sure the Minister will speak for himself on that particular point, but that is not a characterisation I would share. What the competition and Great British Nuclear are doing is giving a very strong signal to businesses such as Rolls-Royce not only that this is a sound technology to invest in, but that there is potentially a very robust market for it in the UK. That is what I would like to see and why I said earlier that when these technologies are considered we need to think about the broader impact on UK manufacturing and jobs that supporting and backing these technologies would bring, not just the manufacture of modular reactors and electricity.
I have met Rolls-Royce and seen its SMR plans and designs. They are incredibly exciting. As the right hon. Gentleman says, this is technology that has been developed for the Royal Navy, and its applications for civil nuclear are very exciting indeed. I hope that it is very successful with it. I would certainly be very happy to see a Rolls-Royce SMR in my constituency at Dungeness.
I do support the introduction of small modular reactors, but I hope the House would not want Rolls-Royce to be given preferential treatment by the Office for Nuclear Regulation in its generic design assessment, because we need to ensure that it is safe. Does my hon. Friend agree that while Sizewell C is now getting under way, it is important that the contractors do honour what they say they will do, such as sourcing the water and ensuring that skills and jobs are happening locally, in order to give people confidence? We know how long these projects have taken to get off the ground.
I agree with my right hon. Friend, particularly on her point about the labour markets, and in the Sizewell area that is incredibly important. I know from Dungeness in my constituency that it is the certainty of having long-term employment that attracts some of the best talent and encourages people, including apprentices, to join the industry. The Minister will probably want to comment on the substance of my right hon. Friend’s remarks.
In the time available to me, I want focus on the site lists consultations element of the civil nuclear road map. The Government are saying that the criteria that were applied to nuclear sites in 2011 should still apply today, and in most cases that is true. Safety, access to water—where appropriate—and grid connections could all be important considerations when it is being decided where the sites could be, along with habitat implications and, in coastal areas, flood risk. All those are constants. The one factor that has completely changed since 2011 is the size of the footprint of the nuclear facility itself.
In Dungeness, an important factor has been the existence of a special protected area as a consequence of the unique shingle peninsula on which it sits, which is the second biggest in the world and a habitat that is unique in Europe, let alone the UK—the biggest shingle peninsula in the world is Cape Canaveral, in the United States. The protections are there for areas of the shingle banks that have never been disturbed. However, there are plenty of areas surrounding existing nuclear sites that are, in effect, brownfield sites where that disturbance has taken place. As they are not in special protected areas, I believe that future development would be possible.
I commend the hon. Member for Folkestone and Hythe (Damian Collins) for initiating the debate. It may not surprise him that I will approach it from a different angle, providing the opposition, as it were.
In my view, this should be called the nuclear road map fantasy. Even if we put aside my objection and that of my party to new nuclear power, all the evidence and all the understanding of the development or non-development of nuclear power in the UK over the past decade point to the fact that this will not happen. As the hon. Gentleman rightly pointed out, the 2011 plan never came to fruition. It is obvious that the nuclear ambitions have not been fulfilled in the past 13 years.
Every pro-nuclear enthusiast seems to ignore the fairly recent market failure whereby Hitachi walked away from Wylfa and Oldbury and Toshiba walked away from Moorside. Notwithstanding the intended competition for the construction of all these new nuclear sites, EDF and China General Nuclear remained the only show in town, and EDF is still the only show in town as the only company willing to build large-scale nuclear. EDF has a blank cheque when it is at the negotiating table, because there is nowhere else for the Government to go. Large-scale nuclear ambitions also ignore the fact that as a concept the EPR design has been a failure, with every single EPR project in the world being over budget, late and experiencing technical difficulties. Finland’s Olkiluoto 3 was 15 years late. Flamanville in France is 12 years late and at four times its original budget. Taishan in China was held up as the delivery exemplar when it was commissioned, but has been plagued by safety concerns owing to rod damage, and has been offline as much as it has been online since it was commissioned.
We were told that the lessons learned from all the problems with all the other EPR projects would be put into place in Hinkley and that it would be much more efficiently delivered, so let us look at Hinkley Point C. In 2016, its estimated cost was £18 billion, but EDF has recently updated that estimate to £48 billion in today’s prices—a mere £30 billion overspend. Instead of generating power in 2025, it will now be as late as 2031. As costs have continued to spiral, the Government’s attitude remains that it does not really matter for the taxpayer, because all the risk sits with EDF.
However, China General Nuclear, which is a partner in the project, has already reached its cap on the money and capital it is willing to put in, so clearly EDF is now having to find a lot more borrowing than it anticipated. Frankly, it beggars belief that the Minister and the Government claim not to be speaking to EDF about this, especially when just last week the chief executive of EDF, Luc Rémont, stated:
“We’re confident we can find a pathway with British authorities on Hinkley Point C and Sizewell.”
When will the Government admit that Hinkley Point C will need some sort of bailout to allow it to get to completion, or is the intention to throw more money at Sizewell to offset Hinkley’s financial black hole for EDF? The Government also need to come clean on why they put back the contractual payment cut-off dates for Hinkley by six years. Do they know that there is potentially further bad news for Hinkley?
The lessons learned have not worked out for Hinkley, but now we are told that it has been a good learning project and that Sizewell C will be different and will be delivered efficiently, learning from the lessons of the delivery of Hinkley. Again, this is head-in-the-sand stuff. The last Government estimate for Sizewell C was £20 billion, but we now know that Hinkley will cost nearly £50 billion, so it is quite clear that Sizewell C will cost £50 billion—a lot more capital than the Government have intimated they are required to raise. It is no wonder that pension funds have been running a mile from investing in Sizewell C.
It is not a straightforward comparison, because I think Sizewell C is still in line with its 2015 prices. It is fairly standard to try to stick with an estimate, but I agree with the hon. Gentleman. As the local MP for Sizewell C, I am concerned that there have been significant delays at Hinkley. I appreciate that the SNP does not approve of nuclear power at all, but I would like to understand why he is concerned that the Government will have to bail out Hinkley C, when that is clearly not the situation. I would be interested to explore why he thinks that is the case.
I quoted the chief executive of EDF, who says he hopes to find a pathway with the British authorities, which suggests that EDF wants to be talking about getting more money. The reality is that if there is a £30 billion overspend, EDF must recover that money somewhere, if it can afford to deliver the project without getting a bailout and in line with the 35-year contract it has for selling electricity. If the company has been able to swallow that level of overspend, it shows that the site rate originally agreed in the £18 billion estimate for construction was way too high, because the original £18 billion was supposed to cover contingency as well. Something does not stack up, given that there is such an overspend and such a delay. The delay means that it will be even longer before EDF starts getting payment for the project, so something is not quite right and we need to get a better understanding of that.
I disagree that Sizewell C is still in line with its 2015 prices. At the end of the day, although some lessons can be learned and replicated, the site for Sizewell C is smaller, more constrained and geologically different. It is surrounded by marshes and adjacent to an internationally renowned nature reserve. It is also in one of the fastest-eroding coastlines in Europe, which is subject to rising sea levels and more extreme weather events. In other words, I would argue that Sizewell C is a daft location for a new nuclear power station. With the groundwork and initial civil engineering that will be required, it is not a straightforward carbon copy of Hinkley. We need to know the official estimate for Sizewell C. Taxpayers deserve some transparency, especially given that the Government have already allocated £2.5 billion of taxpayers’ money to EDF for the development of the project, just to get to the stage of a final investment decision. Enough money has already been ploughed into Sizewell C, yet there is still a lot of uncertainty.
On the wider programme delivery considerations for these large-scale nuclear sites, Hinkley will have taken 15 years to complete, if it is completed, by 2031. Even if we are optimistic about Sizewell C, which will be delivered much more quickly, it is still going to take at least 10 years, so it could be between 2035 and 2040 before it is delivered. These timescales alone show the folly of relying on nuclear for decarbonisation and of planning for nuclear to deliver 25% of generation output capacity by 2050, as set out in the road map. It also shows the folly of the road map stating a delivery target of 3 GW to 7 GW every five years. It is a fantasy target, as is 24 GW overall, unfortunately.
The concept of 24 GW, or 25% of generation output, is the wrong model, given that nuclear power is so inflexible. Such a large nuclear output on the grid means that, at times, even greater constraint payments will be paid for renewable energy companies to turn off their turbines.
Large-scale nuclear cannot deliver the intended five-year targets, so how will those targets be met? As the hon. Member for Folkestone and Hythe (Damian Collins) outlined, the road map talks about small modular reactors. The name sounds innocuous, but do people really believe that a footprint the size of two football pitches is small? It clearly is not, and there is not yet a single licensed prototype in the UK. Good luck in the competition for SMRs, considering that none has been licensed and approved for construction in the UK.
Of the designs that the Office for Nuclear Regulation is considering, the only one to have reached stage 2 is the Rolls-Royce proposal, with the ONR’s stage 2 assessments due to conclude in July 2024. Stage 3 timescales are still to be confirmed, so the reality is that SMRs are just a glint in the UK’s eye at the moment. There is no understanding or certainty on timescales, even if SMRs do come to fruition.
NuScale is supposedly the world leader in SMR technology, and it has just given up on its proposed SMR in Utah because costs have ballooned to £7 billion. The cost of electricity generation has rocketed, too. Our road map tells us that the UK will pioneer and lead the way on new nuclear and SMRs, but that does not make sense. The Government estimate that SMRs will cost £2 billion a go, which makes no sense given the cost of the project in Utah. The Chair of the Environmental Audit Committee, the right hon. Member for Ludlow (Philip Dunne), is in his place, and I welcome the questions he has put to the Government. The Government need to consider this closely, and I look forward to their response.
Why does the road map outline two possible funding models—contracts for difference and a regulated asset base? At a £92.50 per megawatt-hour strike rate over 35 years, Hinkley Point is way more expensive than renewable energy at circa £40 to £50 per megawatt-hour over just a 15-year concession period. When we debated the legislation on the regulated asset base funding model, the Government told us that the CFD model does not work for nuclear as it is too expensive, and that switching to RAB would save £40 billion to £80 billion over the lifetime of a nuclear project. If that is the case, why are two funding models listed in the road map? Are the Government now concerned that RAB transfers too much risk to the bill payer? Are they concerned about repeating what happened in South Carolina where, under a regulated asset base model, a company abandoned the construction of a nuclear power station and ratepayers were left paying for a power station that was never completed? What is to stop that happening at Sizewell?
The road map outlines the need for a geological disposal facility, but there are no plans in place to show how such a facility will be identified, constructed and paid for. What is the estimated cost of a GDF? How big will it need to be? Will it be one facility or will there be more, depending on how many nuclear power stations are built? Worryingly, the road map talks about having interim storage in the meantime. This shows that there is still no solution in place for disposing of radioactive nuclear waste, other than burying it for hundreds of years. Our current decommissioning legacy is estimated to be £124 billion, so why do we want to create another generation of nuclear waste for future generations to pay for? There is always a risk that a future Government will need to pick up the tab for decommissioning, no matter what companies sign up to at the outset.
Finally, we are told that nuclear is required because of its reliability and because it produces power when the wind does not blow and the sun does not shine. Over the last 12 years, however, each nuclear reactor has been offline for roughly a quarter of the year, so the dependability of nuclear is not a given. Indeed, Heysham and Hartlepool power stations are offline and have been since December, so two out of three in the existing fleet in England are offline. Before Hinkley comes online, seven of the original eight nuclear stations operating just a few years ago will have gone offline. If we can operate with such a depletion of the existing nuclear fleet before Hinkley comes online, that undermines the argument that we need nuclear to supply the baseload. The Government clearly do not think that the lights will go out when the rest of these nuclear stations are being decommissioned before Hinkley comes online. To me, the road map seems to be all false aspiration and not enough substance, and it flies in the face of the reality of what we know about the operation of nuclear in the past few years and how the market really sits at the moment.
