Examination of Witnesses (Questions 412 - 419)

TUESDAY 8 JULY 2008

Mr Alistair Buchanan and Mr Stephen Smith

  Q412  Chairman: Welcome to Mr Buchanan and your colleague Mr Smith from Ofgem and thank you for giving up some of your time this afternoon to answer our questions. Thank you too for your written submission, but as it only reached us yesterday afternoon you will probably find that most of the members of the Committee have not had a chance to read it, if you could bear that in mind. If you could speak up, please, that is helpful, it helps with the recording, and if you could be reasonably succinct in your answers that is also helpful. Do you want to say anything by way of introductory remarks or go straight into questions?

  Mr Buchanan: We are very happy to go into your questions and thank you for inviting us here today.

  Q413  Chairman: Perhaps you could outline Ofgem's role with respect to renewable energy. We have received evidence which suggests that most sources of renewable power generation are more expensive than conventional generation; given your statutory duty to protect consumers, does the move to increase the level of more expensive renewable energy cause you any concerns?

  Mr Buchanan: I will split the answer if I may into three and try and answer that succinctly and then come back on the individual parts. In terms of our role in a way we have a multi-faceted role: we have a leadership role with regard to setting network prices and with regard to setting out the offshore regulatory framework, we have a facilitation role which is that we very much seek to understand what is the desire of the Government with regard to the renewables targets—and some of the decisions we have taken, particularly in 2004 where we broke the normal five-year price control cycle to step forward and agree nearly £600 million spend on the grid is a good example of that facilitation role. We have an advisory role, we seek to advise both Defra and BERR on elements of both energy efficiency (with regard to Defra) and renewable policy (with regard to BERR). We think we are listened to but sometimes, as you can imagine, with the critical attention we feel a little but like Nelson at Copenhagen, but we try to make an impact. A very important though often less newsworthy aspect of our job is that we administer nearly all the schemes, so we administer the ROC scheme, we administer the Energy Efficiency Committment and CERT scheme, we administer the Climate Change levy, and that is a very large part of our business, becoming an increasingly large part of our business. We are therefore very much involved, to answer your question, My Lord Chairman, in this. As regards the expense of renewable energy, in a way this will take us when we go into discussion on to various subsidy mechanisms, but the figures that I have seen most recently come from Frontier Economics from June of this year. They are very interesting figures because in terms of a megawatt hour what we are looking at at the moment—these are their figures—is onshore wind between £40 and £75; offshore wind between £40 and £85 and then we take a step up and a barrage at the low end of their charging range would be £140, photovoltaic is £275, which is at the top end of the range, and fuel cell is in the middle at around £175. Those are the latest figures, but what is interesting then is if you slip nuclear in, which is broadly in the range of £60 to £80, and if you slip coal and gas in, which at the moment is broadly in the range of £70 to £80, you have quite an interesting spread of values there. For me the interest is that you have got onshore wind arguably starting to compete with the traditional fuel sources, and that is quite interesting. The final part of your question if I may is our statutory duty, which we take extremely seriously. Clearly, as we look into this winter with wholesale prices going through the roof we are particularly concerned with regard to the fuel poor. An alarming statistic that is always worth hanging onto is that every one per cent increase in power prices that you see is 40,000 people going onto the fuel poor lists. We do take this very seriously and, clearly, one of the features of the renewables strategy is that of a £1,000 bill currently for the average household, £80 is environmental connected—it is the EU ETS, it is the energy efficiency charge and it is the renewable subsidy. I am afraid that is only going to go one way and that is up; therefore we are minded to try and ensure that consumers are very much considered within this debate. It may interest you that we carried out a survey with Henley Associates last year to find out what consumers thought about environmental issues and only 11 per cent of them thought that the environment was not worth worrying about, which in a way was a very encouraging statistic. Certainly, we have to stay very much attuned to consumers and we have just set up both a specialist consumer panel to advise Ofgem and a broad consumer panel so that we can make sure that we are very much attuned to what consumers' appetite is towards in particular environmental spend going forward.

  Q414  Chairman: Could I just ask you just two quick follow-ups then? One is that in the figures that you were quoting for renewables with wind, did those figures include the back-up that is required to deal with intermittency, did they include incremental costs if any of the grid and did they include potentially any loss of power through transmission over long distances?

  Mr Buchanan: To the best of my knowledge it is no, no and no on those.

  Q415  Chairman: The second question is on the first point of your role. Is your role in Scotland and Wales precisely the same as it is in England given that a lot of renewables are expected to come from Scotland and indeed Wales?

  Mr Buchanan: We have a responsibility to all consumers in Great Britain so we do not discriminate regionally either within England or between Scotland, Wales and England.

  Chairman: Thank you. Lord Lawson.

  Q416  Lord Lawson of Blaby: I would like to follow up what My Lord Chairman has just been asking because it is clear that you were asked the question whether these costings that you gave include system costs or back-up costs because of intermittency and the answer was no to both and no to something else too, which means that really they are not worth the paper they are written on as a guide to policy although they may be of some intellectual interest. In light of that I would like to refer to something that you say in your very interesting written evidence, which I have not had time to read very thoroughly because it came a little bit late, but you say "We are unlikely to hit a limit on the amount of renewables and intermittent generation that can be absorbed given sufficient time and money. However, there could be technical challenges in the medium term, for example to 2020 [which of course is the target date] and the costs may be excessive." Can you elaborate on what you mean by these excessive costs—because that is a very strong statement—and if possible can you quantify them?

  Mr Buchanan: Yes. Could I just start with an apology which I should have given to My Lord Chairman with regard to the lateness of the document? We had been wanting to see in particular what the Government's renewable strategy was going to be before we responded and I suspect we are going to come on to talk about that. With regard to intermittency costs, you have seen National Grid, they have signalled that intermittency costs from their perspective could be as high as £1 billion extra per annum with regard to the wind targets that have been set and clearly there may well be additional balancing and system costs that may be included if the EPR design were to be used for the nuclear power stations, so you have got these costs potentially coming through and affecting the consumer. What we do say—and you rightly point to our document—is that broadly the advice that National Grid has provided to you is what we can buy into which is that if the funding is there—and National Grid used a figure of £9 billion to you and the kind of figure that we have seen is six to nine and the kind of figures we have put in our document which you have seen already is that for the offshore £2.5 billion for the first eight gigawatts of power would be the kind of scale, so these are very large sums of money. In addition to that there will be large system, balance and reserve charges, which again National Grid has given to you. It is worth stepping back and saying can National Grid handle that technically? They believe they can and we do have the advantage of starting with an exceptionally strong network, a network that handles at the moment some quite significant swings; it does handle 20 per cent of the power broadly coming from nuclear which at times can be very large base load chunks, we have got nearly five per cent of renewables already, they have quite a large flexibility within the system for voltage reduction so we are starting from quite a strong position, but that is not to deny the question which I think you are driving at which is this is going to place pressure onto the system. Technically in a way the demand is now out to see can we develop forms of storage and battery, can we take that forward, and in terms of cost is this a cost that consumers are going to be prepared to meet. Those are the challenges but it would be wrong to suggest that because of this issue the 2020 target would not be met.

  Q417  Lord Lawson of Blaby: When you say the cost may be excessive—

  Mr Buchanan: The costs will be very large.

  Q418  Lord Lawson of Blaby: Excessive was your word.

  Mr Buchanan: Yes.

  Q419  Lord Lawson of Blaby: You imply also in your written evidence that the costs of, say, nuclear may overall be less than that, you do not say whether they would be or not, you say they may be, and in your opinion it would be much better if the Government had not got a nap on wind power—supported by the Opposition I may say—but let the market decide which was the better. That seems to me to be what you are saying.

  Mr Buchanan: What we try to do—and you will not be surprised to hear me say this—is not to get into Ofgem intimating that we want to pick winners. One of the concerns that we originally had with the renewable obligation, a subsidy approach, was that there was an element of picking winners there by the Government. Certainly with regard to, let us say, balancing and system support costs, the National Grid have given you that figure, which is up to £1 billion; the figure that when I have spoken to National Grid they have discussed that the additional new nuclears may cause to the system is substantially lower than that figure.
