Energy Policy

Lord Teverson Excerpts

Monday 25th June 2018 Lords Chamber

[Lord Stevenson of Balmacara (Lab)]

My Lords, the Hendry report comes out with headline figures that it is important to bear in mind as we think about and discuss what was said in the Statement. The report states:

“Across the National Audit Office’s three Value for Money tests, Tidal Lagoon Swansea Bay can match or outperform the Contract for Difference awarded to new nuclear power station Hinkley Point C with relevant support from Welsh Government …Tidal lagoon capacity can reduce UK system carbon emissions by 36% in 2035 … Lifetime CfD subsidy cost of £302-£390m achieves net positive social NPV benefits of £787-875m”.


That is a factor of more than 2:1, which is a lot better than the return HS2 and some other projects that I can think of will get.

Of course, that is not the whole story. Although the Statement was very strong on direct costs and the problems that the Government would have in justifying them, there are other benefits that would come from a project such as this. This is a first in its class—a first attempt to do something new in alternative energy production—so there is a difference there that cannot be measured in terms of the direct costs of well-tested wind or solar arrangements. There is an amenity, because clearing up Swansea Bay and costing a very small amount to provide something that is visually attractive and also rather beautiful cannot be costed. In order to give confidence to the overall task that we as a country have to make sure we have a diversity of supply, starting things that are new and different would add something that is not easily costable.

In the past two years, the Government have repeatedly kicked a decision about Swansea into the long grass, and the handling of this must surely be agreed by everyone to have been absolutely atrocious. Not only have the Government taken an inordinate amount of time to come to the House today, they have kept Tidal Lagoon Power, the Welsh Government, the trade unions and other stakeholders completely in the dark about what was happening. Indeed, they had to learn about it through leaks in the press. Indeed, it emerged in a Select Committee hearing last month that the Minister had not spoken to Tidal Lagoon Power in more than 16 months. In the last few days there have been conflicting reports indicating that a Statement was coming last week, then that it was coming this week, and then that there would not be a Statement—and now here we are. This is no way for the Government to conduct themselves on an issue that is so important for Swansea, the UK economy, the climate and therefore the world.

The key point here is that tidal lagoon power is a new, world-first technology, and yet it has been judged as if it were just one of a number of things that could be done in order to get us on the path to a carbon-reduced energy supply. The Government’s decision on Swansea tidal lagoon is of public policy importance not only because of its impact but because of the potential it offers the UK economy to meet our global climate change targets.

The project is estimated to generate and support more than 2,000 high-skilled construction and manufacturing jobs. It could engage more than 1,000 businesses in its supply chain—from figures in the Hendry report we know that the supply chain reaches right across the UK—and it could power directly more than 150,000 homes once it is constructed.

I go back to the point about being a pathfinder. The technology that is tried out successfully in Swansea could be rolled around the UK. It is not surprising that we might have problems exporting it since it is a very geography-specific solution. However, given our tides, our climate and our particular style of landscape, it seems to be something that would work in the UK.

Finally, tidal technology could make a valuable contribution to the UK’s transition to renewable energy, which is becoming ever more urgent. The UK is currently on track to miss its globally agreed climate change targets, so the Government’s plans in relation to Swansea Bay and renewable energy generation as a whole are of greater significance than they would otherwise be.

If we are going to have a diverse energy mix, tidal lagoon technology has an important part to play in our transition. The Government say that the costs are too high, but that seems to be a very narrow description of the costs involved. I understand that, even though that is the main reason why they are not going forward, they have not even met Tidal Lagoon Power to work out what additional funding could be supplied by the market. Perhaps when he responds the Minister could tell us what the acceptable cost is that would allow the project to go ahead.

[Lord Teverson (LD)]

My Lords, we on these Benches believe very much that this is the wrong decision. I will very quickly give the reasons why. First, in order to meet our climate targets, we need all technologies to contribute. We believe very strongly—as was shown in a number of studies—that there would be a reducing price in terms of scale as the technology rolled out. We have seen this very strongly with other renewable technologies.

There are other elements to the project. It is also partly an energy-storage project—an area that is particularly needed in terms of the variability of other renewables. And of course, perhaps not in Swansea but in other lagoons where something similar could have happened if this had gone ahead, there is the whole area of flood management that would also save considerable costs in terms of a holistic management approach to the coast.

Of course, the irony is that 2018, the year we are in at the moment, is 10 years after the Climate Change Act, yet between 2016 and 2017 we saw a 56% reduction in renewables investment. So the curve the Minister talked about in terms of our improved performance will go down because of lack of investment. In fact, renewables investment last year was at its lowest since 2008, when the Climate Change Act came in. We are not heading to meet our fourth or fifth carbon budget and we need to reduce our carbon emissions by 3% per annum to get to our target in 2050. So we have an investment crisis at the moment.

The noble Lord, Lord Stevenson, mentioned the time taken over this. The Hendry report came out 18 months ago. I remember that the original discussions were during the coalition Government period. What message is this to investors in renewable technologies? The way that it has been dealt with, the timescales and the opaqueness of the decision taking are difficult to understand, particularly when it was obvious that the Government were going to say no several months ago and have only just got round to giving that reaction and decision.

I come back for a moment to costs and refer to the Hendry review. Charles Hendry was a Conservative politician and Minister of State. He was highly respected across the whole of Parliament when he was an MP. He said about the project:

“I believe that the evidence is clear that tidal lagoons can play a cost effective role in the UK’s energy mix and there is considerable value in a small … pathfinder project … Most importantly, it is clear that tidal lagoons at scale could deliver low carbon power in a way that is very competitive with other low carbon sources”.


That is something that cannot be written off in the way the Minister did.

I have the following questions. Why has it taken so long to take the decision, which was clearly going to be taken some time ago? How are we going to meet the fourth and fifth carbon budgets? Given the regular quote in that Statement about the costs of technologies, when are the Government going to bring back onshore wind, which is the cheapest of those technologies and the one that would help to bring down energy bills tomorrow and in the years to come?

[Lord Henley]

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 my 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.
