Nuclear Regulated Asset Base Model (Revenue Collection) Regulations 2023

Considered in Grand Committee

Moved by

That the Grand Committee do consider the Nuclear Regulated Asset Base Model (Revenue Collection) Regulations 2023.

I beg to move that these draft regulations, which were laid before the House on 15 December 2022, be considered. The Government recently took the historic step of investing in the development of Sizewell C—our first investment in a nuclear project for 35 years—and have designated the project as the first to use a RAB model. In approving the instrument, we would be helping to fully establish the model for potential use on all new nuclear projects, which we need to ensure a low-carbon, low-cost and resilient electricity system, so that we can reach our emission reduction target and provide energy security.

The RAB model offers a chance to do this in a way that draws in new sources of finance at a lower cost of capital, thereby reducing the overall cost of a nuclear project for consumers compared to current funding models. A nuclear company that is designated under the Nuclear Energy (Financing) Act is entitled to receive a regulated revenue stream, overseen by the regulatory authority, Ofgem, which of course has a duty to protect the interests of all consumers. This would cover the cost of activities related to the design, construction, commissioning and operation of the relevant nuclear project, as well as activities related to an approved funded decommissioning programme. These regulations provide the framework to implement secure, long-term funding to nuclear projects.

In accordance with Section 18 of the Act, the Secretary of State may direct the designated revenue collection counterparty, the Low Carbon Contracts Company, to offer to contract with a designated nuclear company. Once the revenue collection contract is entered into, the regulations establish a mechanism for all licensed electricity suppliers in Great Britain to make payments to the counterparty so that it can pay the amounts owed to nuclear companies. The revenue collection counterparty may also return money to suppliers, hold sums in reserve and cover up its losses through requiring suppliers to post collateral and undergo a payment mutualisation process in case of supplier default. The regulations also set out the arrangements for a supplier levy to pay for the revenue collection counterparty’s operating costs.

I will try to be brief in my questions; I am happy to take answers in writing if that is appropriate. I thank the Minister for his very thorough summary of the regulations we have before us today. I agree that this is an interesting way of securing funding for what I think we are all coming to realise is going to be an important contribution to the energy crisis we face at the moment.

The Minister tried to give reassurance about the customer and the role of Ofgem in that. One of our concerns is that this model is complex and long-term. Potentially, if things go well, it could be very successful, but our concern is about if things do not go so well, costs overrun and all those sorts of things. Some reassurance on how customers’ interests will be protected would be very helpful. The other factor in terms of costs is whether we are talking just about Sizewell C or about all the other nuclear projects. Where do we stop? If £1 becomes £10 or £20, perhaps those affected might have more to say about this.

The other concern is that, if things do not go so well, projects get cancelled or other things happen, we are talking potentially about a large sum of money that could be accrued through this model. Could I have a bit more explanation about how the mechanisms could ensure that money not used in the project or any future project would be returned to the customer? There is a concern that the Low Carbon Contracts Company would just sit on customers’ money rather than handing it back. What would the mechanism be to hand that money back?

Moving on, there was a question in the debate in the Commons about whether this will be reviewed or not. There was a suggestion that a review could cause a lack of confidence, and therefore that there should not be one, but the Minister then commented that there will be a review in 2025. It would be good to have some clarification about when a review is a review or not.

I thank the noble Baroness for her questions—and for being the only one to turn up and take an interest in this statutory instrument. Of course, I assure her that we will keep a close eye on the costs. Ensuring that we do not allow the costs to run out of control is probably the most crucial aspect of the project, so both Ofgem and my department will be closely monitoring this.

We can give her the reassurance she is looking for that consumer interests will be protected if there are any cost overruns. Proposals for the RAB model include multiple mechanisms for ensuring that consumers are protected from unacceptable costs. This includes: robust due diligence before a final investment decision to be confident that the project will be effectively managed; requiring a project to move through various staged approvals; and value-for-money tests fully in line with the Treasury’s Green Book. The noble Baroness also asked about how money is returned to consumers through beneficial payments. We will ensure to do that if it is at all possible.

With regard to a review, we have decided not to include a statutory review clause in order to retain stakeholder confidence in the stability of the revenue stream. I think that that is probably in line with the noble Baroness’s thinking. There are plans for the operational costs levy rates to be next reviewed in 2025, and we will then consult on the costs for the next three financial years—that is, from 2025-26 to 2027-28. This is in addition to the other plans that we have in order to monitor and evaluate the effectiveness of the RAB policy, which we will keep under review as necessary or appropriate. As she said, these are long-term schemes, over many years—if not decades—to provide secure funding for the next generation of nuclear reactors in this country.

I thank the noble Baroness for her support. We are grateful for the support the Opposition have provided both for the legislation in the first place and for this statutory instrument. I hope I have resolved her complaints; I am very happy to write to her if there are any additional points.

Motion agreed.

Committee adjourned at 6.31 pm.
