Energy Bill [HL]

Lord Teverson Excerpts

Wednesday 21st October 2015 Lords Chamber

[Lord Howell of Guildford]

My Lords, I congratulate the noble Baroness on the ingenuity of the proposals in this amendment; they are fascinating and make one think very hard, because these are hugely complex issues. Perhaps I may put two questions to her and perhaps also to my noble friend.

First, will this switch to this way of trying to achieve our carbon obligations and decarbonisation lead to cheaper power in the power sector? That must be an important question. We discussed earlier the problems in the power sector and the fact that pushing it too far and too fast may not necessarily help decarbonisation but will have to be paid for in lost jobs. That is bound to be on people’s minds when looking at this kind of amendment.

The second and even more obvious question is whether these arrangements will get the combined-cycle gas turbines built. At present speed, under the contracts for difference regime, and the capacity payments auction and so on, will they get them built in time? We are now entering a very worrying period, with a very low margin of safety in our electricity system—I believe that it will be down to 1.2 gigawatts. When I had some responsibility for these matters, years ago, it was 17 gigawatts. That gives noble Lords an idea of how far we have come down thanks to the rapid closure of many coal-fired stations and so on. Will this pattern lead to that result? These may be layman’s questions addressed to a very complex issue but I would be interested to know the answers. If the implication is the other way, we will have additional costs on power and get further out of line with our competitors. We always have to remember that in the Climate Change Act—behind which the noble Baroness was one of the founding figures and driving forces—there was the reservation that we should not get too far out of line with our competitors. In some areas, we clearly have done; we are out of line. In the steel industry, as we were saying earlier, we have energy charges that fall on at least parts of that industry at twice the level of charges in Germany and, in turn, are far higher than those throughout Europe. I saw one figure showing that they are 10 times the levels in China—which might account for our present woes in the steel industry. In examining this, can we please be guided on whether this will deliver the goods? That is my question.

[Lord Teverson (LD)]

My Lords, I particularly wish to speak to Amendment 78UA, to which I have added my name, but I will start with Amendment 78S, which is the decarbonisation debate. I was certainly very disappointed that the Minister confirmed—he was very clear, and I welcome clarity—that the Government will not take advantage of the opportunities opened to them under the previous Energy Act and declare a decarbonisation target. We have had a lot of discussion about the Conservative manifesto, and in fact the Minister referred to it in the context of saying why that would not happen. However, the words of the Conservative manifesto were completely clear. They suggest that a decarbonisation target would meet both the Government’s objectives. The manifesto says:

“We will cut emissions as cost-effectively as possible, and will not support additional distorting and expensive power sector targets”.

That is very clear.

The point about a decarbonisation target—exactly as the noble Baroness, Lady Worthington, said—is that it moves on from the distorting targets that we had for renewables in terms of decarbonising our energy sector. In fact, because it brings in proper mechanisms in terms of markets and all of that, it is actually less expensive. So, it seems that a decarbonisation target will not only help us very specifically meet our Climate Change Act targets—which the Conservative manifesto fully supports—but provide a route for those targets to be met with a non-distorting and less expensive method than we had under the renewable targets under the EU’s 2020 system and so on. This is therefore a very good and logical amendment. It is almost a vital amendment that the Government should be able to accept to fulfil their own manifesto commitments. I do not say that to make a clever lawyer’s argument; I say it because it is how I read it. It is in plain English in the manifesto.

I move on to Amendment 78UA, to which I have put my name. I pay credit to the noble Baroness, Lady Worthington, for the great role that she played in bringing the Climate Change Act into being. I played a much more modest role in those days on the Front Bench of the Liberal Democrats in opposition—strangely, we are back in opposition again; but there we are. I was going to mention the noble Lord, Lord Taylor of Holbeach, and the fantastic work that he did with me and the noble Lord, Lord Rooker. We helped to deliver, right across the House, together with the Cross Benches, the fantastic Climate Change Act. The noble Lord, Lord Taylor, did a great piece of work.

One of the things that I did then was to try to bring to the attention of the Bill team and Ministers the fact that although those carbon budgets were great, they excluded 50% of the country’s emissions because they took into account the EU ETS trading. So, in effect, government policy only controlled, or had an effect on, about 50% of UK emissions. The Bill team did not seem to understand this—albeit that at the time the department was not DECC but Defra—and nor did the Ministers particularly take an interest in it. I think that the trouble was that, once those in the Treasury understood it—at least, they certainly understood it well ahead of anybody else—they decided that they did not want this at all. Ironically, that was under a Labour Government. However, as the noble Baroness said, the Climate Change Act was a great thing.

--- Later in debate ---

[Baroness Worthington]

My Lords, I reassure the Minister that this is not a matter on which I intend to seek the opinion of the House. It is an issue which I believe we need to discuss in the context of an energy Bill, but I hope that a discussion can be had outside the Chamber. I just wanted to alert the House to the issue because it is materially relevant to the energy policy as it is being played out.

One pillar of the Energy Act 2013 was the introduction of a new support mechanism to help fund extra capacity in the market, designed to complement the contracts being signed for low carbon. It is a very detailed policy with many aspects.

It has come to my attention that the annual auctions of new capacity under the capacity mechanism are bringing forward rather a lot of applications for 15-year contracts from distributed, very small-scale generating plant. Many of those plants are diesel-powered and many others are open-cycle gas turbines of a small scale which are much less efficient than the full-scale CCGTs that are normally built for capacity.

The amendment was tabled to enable us to have a debate on the Floor of the House on an issue which is time-critical, because the next auction will take place in December. Three gigawatts’ worth of small generating plant are prequalified. That is on top of a number of megawatts that were granted in the previous auction that took place last year. So my fear is that, over time, we are starting to see a substantial amount of distributed thermal energy coming forward under the capacity mechanism. Of course, the capacity mechanism creates an incentive to new-build. Having read the Government’s gas strategy, I believe that the Government intended those 15-year contracts to be made available to larger-scale, very efficient, state-of-the-art gas turbines to be there as back-up and to provide us with base-load power. Instead of that, we are seeing coming forward, as a result of significant market distortion, investment in much smaller kit that is far less efficient and much more polluting. The danger is that this drift towards distributed diesel generators and open-cycle gas will significantly affect our ability to decarbonise.

One argument that will be made will be that such generators are there just to catch the peaks and will not operate more than that. However, there is nothing in government policy or legislation that prevents them operating for far longer periods. My fear is that, because of the scale of these plants, they will not be paying a carbon price: they are not subject to the EU carbon price, nor are they subject to the Government’s carbon price support mechanism, which tops up the EU price. That is a significant distortion that we should be mindful of. Markets are nothing if not efficient and nothing if not good at finding loopholes. It will be an unintended consequence of the capacity mechanism rules as they are currently drafted that this will be the market’s answer to our capacity issues.

I visit my mother-in-law in India. Building an energy system in which diesel generators are providing back-up is not a modern-economy solution. There are many other ways to provide safe and reliable power. We should not rely on diesel generation, which is much more what you would find in developing countries that have fewer options and are not able to deliver secure and stable supplies of electricity. We have been doing that for decades and have a world-class grid that enables us to do it. So we are concerned that while we are not letting contracts for clean power, we are continuing to let contracts for traditional fossil-fuelled power, and that there is this loophole in the capacity mechanism rules which allows a far greater volume than anyone would have anticipated of small distributed diesel generators.

In addition to paying no carbon price, such generators also have very loose air-quality standards applied to them—far looser than are applied to larger plant. I do not need to bring the House’s attention to the fact that we have had a rather high-profile problem with diesel in the past few months. “Dieselgate” and VW’s cheating on the standards is a serious issue which helps to explain why we might be struggling to hit our legally binding air-quality standards in the European Union, because if everyone is cheating it is no wonder that our emissions are higher than we thought they should be according to our inventory calculations. So we have an air-quality issue; in fact, the Government have been taken to court over their failure to comply with those air-quality standards. Having a large number of distributed diesel generators operating potentially for long periods through the winter months will not do anything to alleviate our air-quality problems. There is a definite correlation between exposure to the particulates that emerge from diesel and ill-health, especially in younger and older people. So, not just for climate reasons but for air-quality reasons, we should not allow a huge proliferation of this very inefficient and very polluting smaller generating plant—and that we should be giving them 15-year contracts really concerns me.

We know that all Governments in the UK hold as sacrosanct the fact that if you sign a contract with the private sector, you will not then go back on it. That is a tenet that we hold dear in order to preserve our investor credibility. Once those contracts are signed, there will be nothing we can do for 15 years, which worries me greatly. I am not expecting a full and detailed response from the Minister today; I hope that I can just convey the reason for my concern. I hope that I will hear some reassurance that the department is alive to this problem, that it is indeed seen as an unintended consequence and a loophole, and that we are not simply saying, “Ah, well, that’s what the market’s delivering”. That is not sufficient, especially as there are distortions in relation to carbon and not paying the carbon price, and especially in relation to air quality.

Amendment 78V would therefore require that any fossil fuel-generating plant granted a 15-year capacity contract under the capacity mechanism created under the Energy Act 2013 would be subject to a carbon price, so that the Government would apply a taxation policy to such plant; that such plant would be required to fit best-available technology to mitigate air pollutants; and that the Government’s emissions performance standard as was introduced in the Act would apply as well, which would act as a constraint and a break on the number of hours that such stations could run—it would not be a full answer to the problem because it would still allow them to run for considerable periods, but certainly it would not allow them to run unimpeded for an entire year.

Given the position of leadership that the UK rightly enjoys in terms of our sensible policies for decarbonisation and our Climate Change Act, the idea that the energy policy in front of us should lead to us relying on diesel generators fills me with alarm. I hope that we can do something collectively, across all sides of the House, to address this issue before the contracts are signed in December. I think that I have said enough. I do not wish to detain the House any further and I look forward to hearing a response from the Government.

[Lord Teverson]

My Lords, I shall not detain the House very long. I am not sure that the amendment as written is precisely right, but the important principle that comes out of it—I come back to what I said briefly at Second Reading—is that, at the end of the day, the UK economy has to crowd out coal by other generating fuels. Before the election, the Prime Minister, the then Deputy Prime Minister and the then leader of the Opposition together bravely pledged that coal should come out of UK generating capacity. For whatever reason, after the election only one of those people is left in office—the Prime Minister—so on his shoulders rests that responsibility as our Prime Minister to achieve that pledge.

I do not see a great deal of movement from the Government in fulfilling it. It needs to be addressed and this amendment goes some way towards that. But it is a much larger issue which we could solve so easily, probably by using an active emissions performance standard rather than one that is fixed, as it is at the moment, in primary legislation. I hope that the Government—indeed, the Prime Minister and the Cabinet Office—will bring forward proposals to deliver this. In Scotland, they talk about vows; I see this as a vow that is fundamental to our climate change obligation not just to the UK but to the rest of the world.

[The Lord Bishop of Chester]

My Lords, once again very briefly, could the Minister also make some comment in his response about what the cost to the consumer will be of electricity which is generated by plant under contracts under the capacity mechanism?
