Coal-fired Power Stations

Debate between Charles Hendry and David Hamilton

Wednesday 29th June 2011 Westminster Hall

[The Minister of State, Department of Energy and Climate Change (Charles Hendry)]

It is a great pleasure to serve under your chairmanship this afternoon, Mr Howarth. I congratulate my hon. Friend the Member for Sherwood (Mr Spencer) on securing the debate and on the manner in which he introduced it. If there were any doubt about it, he has proved today that he is a very fine heir to the seat of Sherwood. The bipartisanship, expertise and understanding that he has shown on the coal industry and wider energy issues are certainly traits that Paddy Tipping and Andy Stewart had. I very much welcome the debate that he has instigated. It would also perhaps be appropriate to put on the record that the hon. Member for Ogmore (Huw Irranca-Davies) would normally reply to such a debate for the Opposition. He is understandably not here today because of family circumstances and our thoughts and prayers are with him and his family at a very difficult time.

As I say, we have had an important and useful debate. There should be no doubt that we recognise that coal has been and will continue to be an integral part of our energy infrastructure. As my hon. Friend the Member for Sherwood reminded us, coal makes up on average 35% of our electricity generation, but on a cold winter’s day that figure could readily be 50%. It is therefore vital to our energy security. As we have heard during the debate, coal is also the most carbon intensive form of electricity generation, producing around twice as much CO₂ per unit of output compared with a gas-fired power station, together with other environmental pollutants. He put the issue in an international context and outlined the role that coal is likely to play internationally over many years to come.

The imperative of tackling climate change means that we will need to decarbonise our electricity system. In the future, our energy supply will have to be diverse, adaptable and clean. The technologies that can help to deliver that are: nuclear, which should be built without public subsidy; renewable, including biomass, to which I shall return; and fossil fuels with the use of carbon capture and storage. I absolutely agree with the hon. Member for Midlothian (Mr Hamilton) that this should not be a debate about one technology versus another. We need to secure a tremendous amount of investment in our energy infrastructure, and we should be encouraging that to come from a wide balance of resources. I hope that we can agree that our energy security is enhanced by the breadth of that investment portfolio.

As my hon. Friend the Member for Sherwood mentioned, there is certainly a case for having back-up at times when the wind is not blowing, but that would not necessarily have to be coal; it could be gas. At the moment, the investment case would be much stronger for a new gas power plant than for coal with CCS because of the relative costs. That back-up supply could also be provided through interconnectors. For example, an interconnector to Norway could provide a huge amount of potential clean electricity and there could also be additional interconnectors to France or Iceland. They could be part of that process. During this decade, other storage technologies have been developed, such as battery, the use of hydrogen, compressed air or heating hot water. Those are all ways in which one can enhance the reliability of the renewables sector. Nevertheless, we recognise—and the structure we are looking to put in place recognises—that there will also need to be back-up power plant available.

We should also recognise the continuing role for gas in the mix, which has often been missed out in many of these debates. We have increased the expectation of the likely role that gas will play, which picks up the point made by the hon. Member for Blackley and Broughton (Graham Stringer). The world outlook on gas has changed beyond recognition in the past few years and it is right that energy policy should evolve to take account of that reality. When he noted that I was shaking my head, I was not disagreeing with him about the fact that there is an energy crunch, but about the time scale. My expectation is that the problem will not arise in four or five years, but towards the end of the decade.

A lot of new investment is coming through in gas plant. I opened a new Staythorpe 2 GW plant recently in the east midlands and there is also a new 2 GW plant coming onstream shortly in Pembrokeshire. A lot of new investment is coming through in gas; indeed, of the 20-plus GW of consented plant, 60% is gas. A great deal of new plant is coming through, but when we consider that we will lose a third of our coal plant by 2016—it may be more by the end of the decade—and much of our nuclear plant during this decade, there is a real urgency to secure new investment. During this decade, we are talking about an investment figure in excess of £100 billion in terms of electricity generation and the associated infrastructure.

The hon. Member for Liverpool, Wavertree (Luciana Berger) said that we had been drifting in terms of some targets, but I believe it is hard to see that drift. She talks about drifting on the CCS time scale, but in fact, we will secure that first project much quicker than was anticipated under the previous Administration. She talked about us drifting on the renewable obligation review; in fact, we have brought that forward by a full year from the time scale we inherited precisely to give clarity to investors. Where there was ambition before, we have decided to match that with a delivery programme, and put in place a road map for the development of carbon capture and storage, a dedicated Office of Carbon Capture and Storage and a developers forum to identify the barriers to investment, so that we can directly focus on those. I hope that we are putting in place a clear programme whereby we are saying, “We understand what the challenges are. How do we make dealing with those a reality?”

As I said, coal generation remains an important part of our energy mix. UK coal production to date is much stronger this year than last, with surface mine output up 400,000 tonnes and deep mine output up by almost a million tonnes. Consequently, this year, there has been a significant drop in the volume of imports, which I think we would all be pleased about. That is partly a result of destocking and partly because of a steady output from Daw Mill colliery—I was pleased that my hon. Friend the Member for Nuneaton (Mr Jones) was here to pay tribute to that. We very much welcome the development plans that UK Coal has announced for Thorseby and the extension of its life that that might bring about.

Total production in 2010 was up on 2009 at a little over 18 million tonnes, and total coal use was also up. The net effect of contributions from indigenous production and the use of stocked coal was to reduce UK coal imports from 38 million tonnes to 26.5 million tonnes, which is a significant fall of 30%. The generating sector continues to be the main market for coal from all sources, particularly from indigenous production. Some 80% of the coal we consume is used in electricity generation. I want hon. Members from all parties to be in no doubt whatsoever that I, and the Government, believe that there is an important continuing role for coal, including indigenous coal, in the energy mix. We need to put in place the right structure to secure the investment that will bring that forward. Indeed, we also need the right approach to carbon capture and storage.

We know that a third of our coal plant is closing as a result of the large combustion plant directive and that the industrial emissions directive will result in the closure of additional plant. If we reduce the sulphur oxide and nitrogen oxide emissions, it will improve air quality and bring environmental benefits.

I question my hon. Friend the Member for Sherwood when he calls flue gas desulphurisation a simple technology. I have been to Drax to see it. The technology may, indeed, be simple from a chemical and engineering point of view, but it is vast. It covers many acres and costs many hundreds of millions of pounds. The companies that are looking at such technology have to think carefully about the long-term viability of their plant before they decide to go through that process.

It is clear that the market structure as it currently stands will not enable enough new investment to come through in these low-carbon technologies. That is why, during the past year, we have started the process of electricity market reform. Although the old market structure brought benefits to consumers—we had some of the cheapest electricity and gas prices in Europe, although it did not always feel like that—it did not attract important investment in low-carbon technology.

The key elements that make up the electricity market reform process are, first, long-term contracts for low-carbon generation through a feed-in tariff—a contract for difference—linked with a capacity mechanism. That could be used to provide for the additional plant that is needed on stand-by for those cold days when the wind does not blow, for half-time during a world cup football match or whenever additional capacity is required. Alternatively, we could find better ways of spreading the demand more evenly across the day and using that additional plant more sensibly.

The electricity market reform process will also look at the emissions performance standard, which the hon. Member for Liverpool, Wavertree raised. We will set out our plans on that in the forthcoming White Paper. We have listened carefully to the industry. I agree with her that if we set the EPS at the right level, it could be a strong steer towards new investment. Such an approach will make this country more attractive to investors because they will know what is expected of them over the longer term—for example, what the approach to grandfathering will be and when the reviews might happen. The EPS could be a very important steer and plus point in terms of attracting investment into this country, although I think I heard her indicate that there may be a case at this stage for applying it to gas as well. My anxiety about that is that we are not in the position to turn away investors who want to invest in gas at this time, too. We need to be very clear and careful about how it is introduced. The main drivers for low-carbon technology would be less from the emissions performance standard, and more from the feed-in tariff arrangements that we will introduce. We have also said that we will introduce a carbon floor price in 2013, and increasing gradually to 2020. That gives an early and credible long-term signal to investors that we are serious about encouraging investment in low-carbon technologies.

I understand absolutely the point made by the hon. Member for Liverpool, Wavertree. We have been talking closely with the coal industry and other people who are intensive energy users. We have to balance the urgent need to bring forward investment at twice the rate in this decade than was achieved in the previous decade, to meet the security of supply requirements that this country faces, and to do so in a way that does not create carbon leakage. It would not be sensible to drive away from the United Kingdom industries that can be a critical part of our manufacturing process—carbon emitters and heavy energy users. That would only result in that carbon being produced somewhere else in the world. There would be no net gain to the world. We would lose the jobs and have to import the products at the end of it—there would be no gain. That is why we have committed, over the course of the rest of this year, to put in place a series of measures to protect critical industries that are energy intensive users.

That lays the foundations for a sustainable economy, and will help to bring billions of pounds of investment into the United Kingdom through greater certainty. It will help to safeguard jobs, and will help to bring some of that supply-chain investment to this country, too. That is a right and proper target and objective for the Government. It also means that we have to develop carbon capture and storage.

Carbon capture and storage is not a luxury add-on; it is a fundamental part of our energy approach. We recognise the role that coal and gas will play for many years. That is possible with CCS in a way that could not happen without the development of CCS technology. I am pleased to see the progress in this country at a time when we see CCS deployment slipping back in other countries—Norway has put it back to 2018, and Holland is just delaying it, as are other projects elsewhere in the world. Britain remains one of the leaders on this. The £1 billion is the largest contribution that any Government anywhere in the world has committed to a single project. We have built on the work of the previous Government. Paddy Tipping referred to this as the competition without end, because it was going on for so long. I am glad that, in the course of the next few months, we hope to bring that to an end, although it is a complicated process.

The issues raised by the hon. Lady on shared access for infrastructure all need to be tied up in legal contracts with a variety of partners. We want to bring that to a close as soon as we can, ideally in these summer months.

[Mr David Hamilton]

Will the Minister encourage us to find out just exactly what contribution the Scottish Government are making? I believe that the Scottish Government are entitled to make a contribution, if that is the first big project of its kind to go. Of course, never shall the day come when we have separation—because I am a Unionist through and through—but surely it is right for this Government to check and make sure that the Scottish Government make a contribution if that day ever did come.

[Charles Hendry]

Energy remains a retained power. Clearly, the Scottish Government have decision-making powers on planning. That is why they have ruled out such things as new nuclear in Scotland. Nevertheless, energy policy is driven from Whitehall and Westminster. We therefore believe that if this is something that we want to achieve as a national Government, then we should be in the driving seat. If the Scottish Government were to say, “Here is a few million pounds to make it happen”, we would of course be very enthusiastic and grateful to them, although there are not many indications so far that the cheque is in the post. Nevertheless, this will be taken forward by us, as a Government and as the Department of Energy and Climate Change, with a cross-party approach here, and I hope that we can find that agreement in the course of the next few months.

We have a range of technologies, an issue touched on by my hon. Friend the Member for Sherwood. This should not just be about post-combustion technology. We need to look at oxy-fuel combustion and pre-combustion technologies, and that is what we want to see coming forward. In the course of the rest of this year we will set out the nature of the competition for the remaining projects—projects 2 to 4—and look at where we would like that to add to our knowledge, the type of technology that we may wish to see coming through with that, and to apply that to gas, too. Again, the world outlook on gas has changed a great deal and we need to take account of that.

I would say to my hon. Friend the Member for Sherwood that this is a technology that is still in its infancy. We know that the individual parts of it can work. We know that it can be separated—we have seen that done on a small scale. We know that it can be transported and we know that it can be injected into the sea bed. However, nobody in the world has done that at scale, so we do not yet know what the challenges are of doing that at scale, or what the costs will be. In terms of a time scale, to have four projects running by 2020 is extremely ambitious. We are not going to arrive at a stage where we can move it beyond that. We can absolutely see this technology moving forward in the 2020s. Global ambition suggests perhaps 100 projects by 2020, but 3,000 projects by 2050. This is therefore a process that will inevitably start carefully, but then build up dramatically over time. Everything that we are doing here is determined to ensure that the United Kingdom can be in a real leadership position. What we also see from industry shows that it wants to be part of that process. The NER300 process is a European competition, and almost half of the schemes coming forward for CCS are in the United Kingdom. That shows the appetite among our industry, our universities and our whole supply chain to help lead in this area.
