Energy Bill
Debate between Lord Grantchester and Baroness Maddock
Lord Grantchester
I am grateful to the noble Lord, Lord Teverson, for his introduction to the debate on the demand side of energy. He is quite right to draw attention to this. Although other noble Lords may have been teasing in their remarks, the Second Reading debate highlighted that the Government are coming rather late in their thinking to these subjects, and our later amendments will explore all the different technicalities on the demand-side responses. Therefore, we are happy to support the wider recognition of the importance of demand-side response.
I turn to the proposed new paragraph in his amendment on making the efficiency measures EU-compliant. Again, we note the position that we are in at the moment and that the directive requires member states to set an indicative national energy efficiency target based either on energy consumption or on energy savings, or indeed on energy intensity, as the noble Lord, Lord Teverson, suggests in the amendment. We wonder how that might take account of the decarbonisation challenges that we will be facing. Also, we will be monitoring more than one change at a time to take into account GDP changes. Therefore, we would be very interested in knowing how the Government view this measurement of energy efficiency.
Turning to Amendment 55ZA, which concerns pilots, once again we note that the Government are coming rather late in their thinking to the demand side and that they therefore want to make provision to help their thinking to progress by running a pilot scheme. Clause 37 gives the Government powers to run a pilot scheme for electricity demand reduction. While the clause does not specify that this pilot scheme should take the form of a pilot capacity auction, it is clear from the consultation response that that is what DECC is considering.
However, the capacity market is primarily designed to ensure capacity throughout troughs in supply, and it will therefore reward only demand reduction projects that reduce the amount of generating capacity that is needed at such times and not those that reduce demand at other times. A capacity market therefore rewards energy efficiency only for its security benefits and not its other, much larger benefits in terms of emissions reductions and affordability. Therefore, we are aware that an additional policy is needed to enable small businesses and households, and not just large infrastructure projects, to be rewarded for saving energy.
Such “premium payments” were favoured by the majority of respondents to DECC’s consultation but were then dismissed by the department. A further explanation in this regard would be welcome. Therefore we support the call on Her Majesty’s Government to clarify whether DECC should bring forward multiple pilot schemes to include premium payments, a capacity market and perhaps other forms of incentives. This would demonstrate which scheme or schemes were most effective in delivering permanent demand reduction in practice.
Amendment 55ZA also mentions how these pilots might be financed. Clause 37 states that it will be paid out of government funds rather than through consumer prices. However, following the spending review, a figure of £75 million for investment in innovative energy projects was mentioned. I understand that DECC suggests that only about £25 million of this will be available for the pilot. In any event, those sums are dwarfed by DECC’s own assessment of the cost for full capacity auction. Amendment 55ZA would allow pilot reduction schemes to be funded at least in part from capacity payments either in advance or during a capacity auction period. Will the Minister clarify to the Committee where the Government have got to in their thinking?
Baroness Maddock
My Lords, I support my noble friends in trying to highlight the importance of demand reduction and the fact that this Bill came rather late to it, as has been said by others. I was somewhat confused by some of the earlier comments from those who said that they were in favour of energy efficiency but were not sure about demand reduction. If you increase energy efficiency, you reduce demand. That is fairly logical. I find some of the comments a little curious.
I emphasise the fact that if the Government are having only one pilot that will be only around the capacity market, that will not be good enough, which is why we have tabled these amendments. As regards the amendment in the name of my noble friend Lord Roper, if the Government were to take something like that forward, we could have a demonstration about which scheme or schemes are the most effective in delivering permanent demand reduction. In a sense, that ties in with the amendment of my noble friend Lord Teverson. There was a lot of criticism of my noble friend and talk about the difference between demand management and demand reduction. They are two different things. We have had some strange logic in today’s debate.
Unless we have several pilots, there will be no meaningful comparison and we will not be able to decide which are the most cost-effective and the most effective in reducing demand. I support my noble friends in their efforts to make demand reduction more of a priority in this Bill.

Debate between Lord Grantchester and Baroness Maddock
Baroness Maddock
My Lords, my name is attached to the amendment. I was not going to speak because of time, but the noble Lord, Lord Jenkin, has reminded me of a presentation that I had some years ago. I may have got the town wrong but I think it was Barnsley. It was in a coalfield area. The local authority there used coal for the district heating in its blocks of flats. I will always remember the description of the terrible mess that the coal dust made everywhere; the women who lived in the flats hated it because they always got coal dust in their curtains. The story is that they changed over to local biomass, which was interesting biomass because it was entirely what they gleaned from trimming and pruning trees and shrubs in the local area. Enough was produced, so it did not have to travel a long way but was enough to replace the coal in these blocks of flats, and the ladies with their curtains were delighted because they did not get soot any more. That has stayed in my mind.
When people first started looking at biomass, that is the sort of thing that they were thinking about. However, when you start to go into some of the ideas about bringing all sorts of things from America—we have just heard that they do not certify their wood either—then it is a completely different issue that we need to look at more carefully. Still, I thought the Barnsley system was pretty good.
Lord Grantchester
Like the noble Lord, Lord Teverson, we agree that biomass could make a significant and important contribution to the UK’s renewable energy thorough the use of sustainable feed stocks from waste. Again like the noble Lord, we agree that biomass should be sustainable.
The current plans would result in a rapid expansion of large-scale biomass electricity generation, principally through the full or part-conversion of existing coal-fired power stations. The EPS establishes a maximum level of emissions for electricity generated by a power station over a year. However, the only emissions that it recognises are those from fossil fuels, while biomass emissions are counted as zero.
As other noble Lords have argued, emissions from biomass can be interpreted as being quite substantial, as they should include emissions associated with the planting, growing, harvesting, processing and transport of biomass. This is in addition to the increase in emissions as a result of carbon debt—that is, the time it takes for tree regrowth and recovery of carbon stocks. Indeed, the sources of the stocks are also to be taken into account in sustainability requirements.
Many coal-powered plants are planned to be converted partially or entirely to biomass to extend their operating lifetimes and to benefit from the substantial subsidies available under the renewable obligations. A conversion to biomass under these amendments would trigger the EPS to cover the whole power station, including the life-cycle emissions from biomass. The amendments would complement the Government’s own proposals for sustainability standards for biomass generators, which include a life-cycle greenhouse gas emissions standard for emissions from harvesting and processing. We entirely support the intention that the EPS is triggered should any generation from biomass take place. If that is not to be the case, there is a danger that a plant close to breaching its limit might convert to a small amount of biomass in an attempt to remain under the threshold.
