Energy Policy — House of Lords, 2018-06-25
Topic: Energy
Oliver Michael Robert Eden (Conservative, Centre-right): My Lords, I thank both noble Lords for their contributions and for their questions. I hope that I can deal with the points they made I will start with the point made by both noble Lords about the delay in getting the decision right. I have to say that the noble Lord, Lord Stevenson, in a sense answered that point. The important thing was that we wanted to get the decision right and wanted to look at it as a whole, not just in relation to the cost of energy but also taking into account all the other factors that the noble Lord mentioned, including, for example, the amenity advantages and—this was raised in another place—the use of steel and the effect that that might have on the Port Talbot steelworks. Of course we did. We looked at those issues, which made the sums much more complicated. At the same time, we were also seeing quite a reduction in the cost of offshore wind, as the Statement made clear. I quoted those figures; the reduction complicates matters further. It also makes clearer the case put forward by right honourable friend about making this decision. That is why—at the right point, I would say—my right honourable friend came to another place and made decisions. It is my privilege to repeat them today The noble Lord, Lord Stevenson, asked about other potential benefits. There are some, which we looked at. In the end, one has to come back to them, whether they are amenity advantages or jobs in the construction phase, as mentioned by the noble Lord, Lord Teverson —or perhaps it was the noble Lord, Lord Stevenson. The benefits are necessarily limited and the jobs are limited to the construction phase. Though great, the amenity benefits are not enough to deal with the fact that, over the period of this project’s existence, we will still pay three times as much for electricity as for electricity that could be obtained from offshore wind, because the cost of that wind has reduced so much The noble Lord, Lord Stevenson, also talked about the need for diversity of supply. Again, I have discussed that at some length in this House a number of times. Occasionally, I put to noble Lords on the Liberal Benches the need to look at the advantages that might come from the extraction of shale gas. I know that the noble Lord, Lord Teverson, does not like to comment on that, but his noble friend Lord Bruce offered praise for shale gas, whereas his noble friend Lady Featherstone is not so keen. The noble Lord, Lord Teverson, looked as though he did not want to comment on this when we discussed it last week. We want diversity of supply because, as made clear by the noble Lord, Lord Stevenson, it brings us security. We want security, but not at excessive cost. I will not rehearse the figures in the Statement about the potential cost, but it is too great on this occasion The noble Lord, Lord Stevenson, also talked about new technology and the possibility of costs coming down. On this occasion, I do not think that the technology is particularly new. We are talking about boring earth, concrete and other things with steel into the ground or the sea to make barriers. That is the major cost. I do not think there is the scope for cost reduction that came with the development of offshore wind, where we saw installations getting bigger and blades getting more efficient. As a result, we saw the great advantages of technology moving forward. Here, we are dealing with what one might call relatively old technology that will not come down in cost The noble Lord, Lord Stevenson, asked what the acceptable cost was. As my right honourable friend the Secretary of State made clear in another place, he was not prepared to put a figure on the cost because other factors would be taken into account for each project, which we would look at in the context of other possible benefits and the cost of the electricity. We are not ruling out the prospect of tidal lagoons in the future but this particular one looked expensive. Other tidal lagoons might be cheaper if they are bigger. There are economies of scale in electricity costs. Each project would have to be looked at individually Both noble Lords talked about the reduction of carbon emissions. We accept that there would be such a reduction in this case. We want to go on doing what we can to reduce our emissions as much as possible. But again, as I want to make clear, we can do that only when taking costs into account. I want to comment briefly on the alleged reduction in investment. There has been a reduction but a great deal of investment was made. We have seen rapid growth in renewables since 2010. We have seen the use of renewables go up from 6.9% in 2010, at the beginning of the coalition, to around 30% today I think I have dealt with most of the points made by noble Lords. I hope they will accept that, in the end, the case is pretty clear. The scheme was imaginative and good, and it was right that we looked at it in some detail, but the cost of the electricity is just too great.
