Domestic Renewable Heat Incentive Scheme (Amendment) Regulations 2018

Debate between Lord McNally and Baroness Featherstone

Wednesday 9th May 2018 Grand Committee

[Baroness Featherstone (LD)]

The delay to the laying of these regulations has been hard for the industry. We will not stand in their way; however, perfect they are not.

I am sure the Minister will understand the need to keep a watch on their effect as they come into being as there may be unintended consequences—some of which I shall run through. I seek the Minister’s assurance that the Government will keep them under review and make further changes and revisions where needed. I shall put forward a raft of suggestions in that vein.

One of the shocking aspects of the RHI is how far short of the expected targets it has fallen, as mentioned by my noble friend Lord Teverson. I was watching the Public Accounts Committee session on the RHI and was astonished at the BEIS response to questioning from the committee on the fact that the original target for number of installations was 513,000 by 2020 but, as was mentioned, only 78,000 had been installed by December 2017, as stated in the NAO report.

The BEIS response was even more shocking because it was that this meant we had saved money and that was a good thing. BEIS prayed in aid unsubsidised companies which were doing brilliantly. The Government would reach their targets for emissions reduction and renewable energy production anyway, so it did not matter. I thought that was a concerning approach to the desperate need to decarbonise heat.

The NAO report demonstrated that the ambition of the Government in this regard has been scaled down from their original ambition. The proportion of renewable heat that will not be eligible for RHI has gone up by 270% and the lifetime emission reduction resulting from the RHI has gone down by 44% compared to the original ambition. The Government are not on track at all to reach their fourth and fifth carbon budget targets, and they will be missed. We were all celebrating when we signed the Paris agreement, yet there has been no step change in actions to match the step change needed to meet our commitments, particularly on heat. In terms of our debate today, there is a cliff edge coming in 2021, so will the Minister say what is the Government’s plan? What is going to happen when the scheme ends? The Government have said that they will bring forward lots of studies this year and report on their review in the summer of 2018, which is nearly upon us. Can the Minister be explicit in his response and tell us what we can expect to see and when we can expect to see it?

As the Minister said, there has clearly been a lot of gaming to get subsidies that are not in the spirit of this agenda. Can he tell me how many companies have been caught gaming the system? In the committee, it seemed that most of the checking is done at the point of accreditation and there is relatively little in terms of inspection and audit. If we need regulations changed to clamp down on this, perhaps the Government should also be looking far more strictly at their compliance regime.

I want to address one of the changes in these regulations that have been brought in to address some of the gaming that was mentioned; the drying of wood. It is obviously not the intended purpose of the subsidy, and companies which game the system should be ashamed of themselves, but shame clearly is not working. I totally understand and support the Government’s desire to make changes that will exclude this type of gaming, which unfairly means that those who play by the book find themselves at an economic disadvantage, and margins are extremely tight.

However, there are potential unintended consequences of the new regulations about feedstock rules, and I should like the Minister to address this issue. The regulations in relation to AD rightly want to encourage the use of non-crop feedstock. That means that there will be a greater need for feedstock processes, such as pasteurisation or hydrolysis, to make sure that digestate is safe to lay across the land. It also means that a wider range of feedstock will be used. This is not my specialist subject, but removing potential bugs from the digestate, meeting the requirements of the Environment Agency and reassuring end users that the digestate is okay to spread to land seem pretty important.

As we rightly shift to non-crop feedstock, this will become a bigger issue and the need for these processes will increase, so companies doing the right thing may find themselves penalised economically for doing so under the new rules. Going forward, all RHI projects will use some waste feedstock, and the change to waste eligibility potentially rules out these uses. If the RHI subsidy is not allowed for plants using these processes, projects may be unable to go ahead. The original consultation referred only to withdrawing support from drying “industrial or municipal waste”, and it is a good move in these regulations to remove the ability to game in that way. Is it intended that the policy should also capture pasteurisation and/or hydrolysis in AD plants with the exclusion process for waste? If that is the Government’s intention, how will it work if only a proportion of the input feedstock is waste? Does it mean that even a tiny amount of waste feedstock would render all heat generated ineligible for support? Could the amount of support paid be adjusted based on the proportion of waste feedstock used?

There is a call from some in the industry for flexibility in the system, as there is a difference between AD projects that use heat for pasteurisation or hydrolysis as opposed to blow-drying wood. To indicate some of the financial implications, although each plant is different, this one is an example of potential financial implications on set-up. Funding projects with a current long-term investor requires returns of minimum 8.5%; it would need to be more like 9.5% to 10% on the open market. For an average plant, therefore, the overall cost to build is £12 million. The RHI heat income that would be lost if the changes are interpreted as “no RHI paid on heat for pasteurisation or hydrolysis if any waste is used” means that £880,000 would be lost over a project’s lifetime, taking 0.4% off the project’s returns. Given that these projects are only just achieving the required level, a project that is just about fundable now would not be funded as the return would fall to only just over 8%.

I know that is very detailed. I obviously want to give the Minister time to think about this, but these issues have been raised by the industry. The Minister is getting sympathetic looks from my noble friend on my right. My point is that this is detailed and close, but when margins are close, this is important. We want to encourage these people to set up new plants, not discourage them. This needs looking at and we need to keep an eye on it because it puts people out of business. As small as it seems, it is hugely important.

[Lord McNally (LD)]

I intervene to say that this matter illustrates the importance of these committees, where the industry and Members are able to put on record real concerns that both Ministers and the learned people behind them can take on board for the future.

[Baroness Featherstone]

I thank my noble friend.
