Domestic Renewable Heat Incentive Scheme (Amendment) Regulations 2018

Lord Teverson Excerpts

Wednesday 9th May 2018 Grand Committee

[Lord Henley]

I am grateful to the noble Lord. As I said earlier on, I will endeavour to improve; I know that the noble Lord will keep a record on these matters.

The purpose of the draft orders is to implement reforms to the renewable heat incentive, or RHI. The reforms will deliver changes that will strengthen the focus on long-term decarbonisation, offer better value for money for taxpayers, increase protection for consumers and further support supply chain growth in the renewable heat sector. Heat accounts for around half of the UK’s energy use and one-third of total carbon emissions. Increasing the share of heat derived from renewable sources is a critical challenge, both to meet our renewable energy targets and to deliver the Government’s long-term carbon goals. Building a vibrant renewable heat sector is a key objective of my department’s clean growth strategy and the industrial strategy. The RHI is the main programme to deliver those goals over this spending period. Before the RHI started, only 1% of our heat came from renewable energy sources; that figure is now around 7% of total heat.

This type of tariff-based support for renewable heat is the first scheme of its kind in the world. Inevitably, there are lessons to be learned, and these reforms are a response to some of the lessons from the early years. The National Audit Office published a review of the RHI in February this year, which we were pleased to receive. Many of its comments related to issues covered by the draft regulations, which I hope will go some way towards addressing some of the issues raised by the NAO, which were also noted by the Secondary Legislation Scrutiny Committee. The draft orders will deliver a series of important reforms that will help us to deliver a more strategic mix of technologies and improve value for money over the next three years until the scheme closes in March 2021. I will highlight the main ones.

We will increase the tariffs available for biogas and biomethane technologies while introducing new restrictions on the feedstock that those plants use. That will encourage the increased use of food and agricultural waste and will reduce the use of energy crops, making better use of farmland for food production. Alongside changes already made last year, this will rebalance deployment away from biomass in favour of heat pumps, biogas and biomethane, which will all play a much stronger role in the scheme over the long term.

Another important change is that we will bring in tariff guarantees that will allow RHI applicants to secure their place on the scheme in advance of construction. This will support investments in larger plants that deliver better value for money. We will cap the amount of heat covered to 250 gigawatt hours per year to protect the scheme budget.

In the domestic scheme, take-up to date has been dominated by owners of larger homes. To promote wider uptake, we will introduce the assignment of rights. This will allow third parties to finance renewable technology and to be repaid directly from the RHI. Crucially, that will open up access to the scheme for those without up-front capital to pay for a new heating system.

Following consultation last year, we will limit the eligibility of certain heat uses. These provisions will remove most instances of wood-fuel drying and waste processing or drying. In addition, we will remove the use of heat for drying digestate in anaerobic digestion facilities as an eligible heat use. We consider that these processes are poor value for money and that many would not exist without RHI support. We will also remove support for heating swimming pools on the non-domestic scheme, unless the pool is for commercial or municipal use.

We are also introducing changes to allow more than one heat pump to use a common or shared ground loop. This should facilitate greater deployment of that important technology. The introduction of electricity metering for heat pumps across both schemes will allow participants to better monitor the efficiency of their plant and build confidence in the technology.

Following consultation, another change will be to increase the power efficiency threshold of combined heat and power technology from 10% to 20% to reduce the risk of overcompensation and to encourage plants to run more efficiently. There is also a whole series of mainly administrative changes to tighten cost control, reduce the risk of gaming and improve Ofgem’s delivery of both schemes, including by tightening its enforcement powers.

The Renewable Heat Incentive Scheme Regulations 2018 also consolidate all previous revisions to the original regulations, as recommended by the Joint Committee on Statutory Instruments. The RHI plays a central role in the Government’s programme to decarbonise heating. These regulations are an important step in refining the scheme and I commend them to the Committee. I beg to move.

[Lord Teverson (LD)]

My Lords, in general, I welcome this secondary legislation, in that the National Audit Office report from February certainly needed some reaction from the Government on the way that the scheme operates. Just to put it in a bit of context, the audit report included some very interesting figures: between 2012 and 2017, there have been some £1.4 billion-worth of payments, which should lead to commitments of some £23 billion. To me those sound like big numbers but, as we know from smart meters, they are absolutely piffling. There have been 78,000 installations already and there were expected to be 500,000 by 2020. It is estimated that we have got to about a fifth of that original target. To give the Government their due, they have responded to reality in this area and moved some of those targets.

Although the Minister made a strong point about this being a major contributor to our carbon targets, the point I want to make is that, in many ways, it is a small drop in the ocean of what we need to do to meet our carbon budgets in future. The renewable heat incentive is certainly nothing like sufficient to meet those budgets in the heating sector, nor was it ever meant to be. That sector is so important, but it is one in which we still have so few solutions for meeting our targets. In electricity generation, we are well on our way; in transport, we at least have the solutions on hand; but in space heating, we do not yet, and the RHI is never going to get us there. There are big challenges for this scheme.

I was quite surprised to see in the audit report that Ofgem, which is the manager of the scheme, had not really managed to tackle some of the gaming issues and was uncertain on the overpayments side. I guess that all auditors have to find something. Certainly, the report praises the GB scheme in comparison with that in Northern Ireland, where clearly the scheme got completely out of control and caused the political difficulties that we now have there. However, it is estimated that we still have some £3 million-worth of overpayments.

--- Later in debate ---

[Lord Henley]

My Lords, as always, I make the offer of a letter to all noble Lords who took part in the debate, because obviously I will not be able to pick up all the points. I am grateful for noble Lords’ general welcome for the regulations and our response to the NAO report.

The noble Lord, Lord Teverson, talked about this being a drop in the ocean given the large sums of money that are involved—we all know that a billion here and a billion there soon adds up to quite a large sum. Take, for example, AD, which was mentioned by the noble Lord, Lord Teverson, and the noble Baroness, Lady Featherstone. We know that AD will never solve all our problems, but it can deal with a certain amount of waste. As was pointed out by the noble Lord, Lord Teverson, the important thing with any AD plant is to make sure that you have adequate waste as feedstock for the future. We do not want people producing waste for the sake of waste just to go into a plant. We want to use only genuine waste or, on occasion, to top it up with a certain amount of crops that are grown for that purpose. Principally, however, plants would be designed to deal with waste.

In my former life as a Defra Minister, I saw quite a number of AD plants taking in waste from very different sources. Where they were attached to a supermarket, one would see bucket loads of old yogurts or whatever else had gone past its sell-by date being tipped in. That was a good way of using it, and we want to devise schemes that will, as the noble Baroness rightly said, prevent that waste going to landfill. I saw excellent small schemes also. I remember one used by a salad producer, which took the waste from its own products—the stalks from tomatoes are actually rather difficult to break down—and used it to produce both heat and power to grow more tomatoes in due course, and used the digestate that comes out in the end to fertilise those tomatoes. It was, wonderfully, almost a closed loop. There are terrific advantages to AD, but, as we all know, it will not solve all the problems.

RHI will be an important step in helping to reduce carbon emissions and—I say this to the noble Lord, Lord Teverson—make progress towards the legally binding renewable energy targets that we have. As I made clear, we will certainly look very carefully at ensuring that there is suitable waste feedstock and that the scheme ensures current and future supplies to anaerobic digestion. If the noble Lord has a local problem in the south-west, it is important that he, and those in that world, brings it to the attention of the department when it is reviewing this matter. I assure the noble Baroness, Lady Featherstone, that my right honourable friend Claire Perry and the department will look constantly at these matters to make sure that there can be further tinkering to get it right.

The noble Lord, Lord Teverson, asked about solar thermal. My understanding is that it is eligible for both schemes, so it is already supported by RHI. If he wants to look at that for his own domestic arrangements, he is welcome to do so.

As I said, I very much welcome what the noble Baroness, Lady Featherstone, had to say. I made it clear that we will keep these matters under review. I cannot give a precise date for when and how my right honourable friend will respond. I will certainly respond to some of the noble Baroness’s more detailed questions, particularly those relating to electrolysis and other matters, most of which I shall make a complete hash of if I try to respond to them now. I think all those taking part in this debate would be far more grateful for a written response.

The noble Baroness is right to raise the whole question of detecting abuses and gaming—something touched on by other noble Lords and which the NAO was wary of. As she pointed out, with any changes that we make, there are always potential unintended consequences, and we keep that under review. It is a large and varied scheme, and the non-domestic scheme in particular has huge variation in size, heat and use and the technology used between projects.

Despite all those challenges raised by the NAO, the department—the former Department for Energy and Climate Change, which noble Lords on the Liberal Democrat Benches will know well because it was one of their great Secretaries of State who sat in that department, which is now within BEIS—is working with Ofgem and, I think, developing a better approach to identifying gaming. We will certainly respond to the NAO in due course.

The noble Lord, Lord Stevenson, also welcomed the changes, and I am again grateful. He particularly welcomed the assignment of rights, but was concerned that it might lead to a lack of access to loans or other finance for a number of businesses and that that could be a barrier for them. I can only say that we have no plans to widen the assignment of rights beyond the household sector at the moment, but we would always want to keep all matters under review.

[Lord Teverson]

What is the logic to that? The issue for small and medium-sized businesses is exactly the same as for domestic users: it is about high capital outlay, which is equally difficult for SMEs as for private, domestic householders. This has really got in the way. The Government have a great solution there now for the domestic sector; if the principle is being breached, I do not see why it is a difficulty to extend it to the SME sector.

[Lord Henley]

I appreciate what the noble Lord says about there being no logic to it. It is just that there is no evidence at the moment that lack of access to loans is a barrier to business. If the noble Lord thinks otherwise and can produce evidence, it can be looked at.

As I said, the order has largely been welcomed, and I am very grateful for that. These changes are necessary as a result of the NAO report. I think that we would all agree that there have been considerable successes this year. It is only part of the whole scheme of trying to decarbonise the system—again, we wish to pursue that even further.

I want to pick up on one final comment from the noble Baroness, Lady Featherstone. If I could persuade her and some of her Liberal friends of the benefits of what she referred to as fracking and of pursuing greater domestic production of gas—of which there is potentially a great deal in this country—in that it improves both our chances of a degree of decarbonisation and our energy security, I would feel that I had achieved a very great thing. That will no doubt come in the future. In the meantime, I will give way before I finally put these regulations to bed.
