My Lords, I thank the Minister for his excellent introduction to these regulations and other speakers who have contributed. It is a truism to say that these regulations are an important part of decarbonising the economy and reducing greenhouse gas emissions in line with our international commitments and targets. The key question has to be whether these regulations before us will help us in our drive to achieve the Government’s stated aims, which include a,
“focus on long-term decarbonisation, promotion of technologies with a credible role to play in that transition, and offering better value for money for taxpayers”.
I couple that observation with a question to the Minister: does he agree that the evidence before us—which, as has just been said, is not complete by any means—seems to show that we have been less successful in reducing carbon from heat in this country than we have been in decarbonising electricity generation? It may be that that is a lesson that we need to learn and expand upon during this process.
The noble Baroness, Lady Featherstone, has just said that we are approaching a cliff-edge. Not only is this scheme time limited, but we have had very little information on how the Government are going to drive this policy through to 2030 and beyond and, indeed, on whether they are focusing sufficiently on decarbonisation or are falling into the trap of choosing some current technologies over others, which experience tells us is not the way to go. We need to go single-mindedly for the higher carbon-generating technologies and stick with that before we start playing around with too many other options that may well not be as efficient in getting us to the target.
Turning to the regulations, we do not disagree with the proposed changes. There have already been delays that have been far too long, revisions and seemingly endless consultations. The most important thing is to get on with delivering progress in renewable heat generation. However, we have to bear in mind, as the NAO report, which has already been mentioned, has brought into clear focus, that this reset of where we currently are translates into a very severe overall reduction in ambition. Can the Minister give us some indication of the longer-term plan that the Government have for renewable heat, and of what exactly the plan will consist? The ambition, which I thought all parties shared, of a substantial decarbonisation of heat cannot be achieved on the RHI alone. Indeed, as has been mentioned, these regulations are going to end, and will be closed to new entrants in March 2021. This is very short-term target and few, if any, new projects can be expected to be devised, tested and financed, or even introduced, in that timeframe. So, while we welcome what is being done, the Government need to answer some key questions: what is going to happen next and when will it happen? Where is the research on different
heat-demand scenarios? What is the future for hydrogen, which recent reports have talked up? What changes will be needed in the grid, for example, if there is a large- scale uptake of heat pumps, and who will pay for that? What is the proper role of bioenergy, given its sometimes adverse impact on the natural environment? All we know is that the Government intend to publish a full report on the evidence by summer 2018, which is not, frankly, enough, and is, of course, already too late.
We have, as the Minister said, the benefit of a NAO report, which was picked up by the Secondary Legislation Scrutiny Committee. The key point that emerges from that is that the amount of renewable heating funded by the RHI will have reduced to 65% by 2020, and the lifetime carbon emission reductions achieved by the RHI, in terms of the current ambition compared with the original starting ambition, is a reduction of 44%. This is a substantial downgrading, which is very disappointing. As a country, we surely deserve better.
I have some specific questions for the Minister, some of which have been raised already. On the assignment of rights, which we agree is important, surely it is important for both domestic and non-domestic RHI, but the regulations restrict it to domestic. Can we have an explanation of why that is the case? On tariff guarantees, the regulations are sending the wrong signals; people need certainty, and making these TGs subject to closure if the guarantee amount is exceeded in any particular period is obviously is helpful in capping the costs, but will be disastrous because they leave investors and operators uncertain about the likely financial return they will obtain from their investment. We welcome the geothermal element in the non-domestic scheme, but the funding identified seems very ineffective and insufficient. Can this be looked at again? Finally, I am surprised at the outturn position of 20% adopted on the CHP efficiency threshold, as 71% of the consultation responses disagreed that the level should be returned to 20%. The argument goes that CHP, because of its variable outputs, does not work on the basis of a known level of electricity certainty. By setting the level at 20% as if it were achievable across the board without exception, the scheme potentially undermines the viability of good CHP schemes that cannot operate entirely on that basis. I would be grateful for a comment from the Minister on that.
I look forward to the response from the Minister, but I echo what has just been said by the noble Baroness, Lady Featherstone: if he wants to add to his letter-writing, I am sure that we can wait for that.
