My Lords, I welcome the continuing interest shown in electricity-demand reduction. My noble friend Lord Roper’s Amendment 48 raises an issue that came up a number of times at both Second Reading and Committee—namely, that multiple pilots are necessary in order to test a variety of approaches. One of the pilot’s key aims is to test the Government’s preferred approach of delivering electricity demand reduction through the capacity market. That said, from a legal viewpoint the amendment is unnecessary as the Secretary of State is already able to design and run a pilot, or pilots, to test different approaches if this is necessary.
Before I move on, I, too, add my congratulations to the right reverend Prelate the Bishop of London on the great energy reductions he has achieved, which just shows that behaviour change towards energy usage can make a huge amount of difference. I commend what the right reverend Prelate has done. He also mentioned the very important Green Deal and smart meters. These measures will help to revolutionise the way we approach energy usage. It is about being able to ensure that consumers understand the usage of energy, which is why I listened very keenly to what the right reverend Prelate said. Where the Green Deal is concerned, 80,000 assessments have been carried out. Under ECO, many tens of thousands of homes have already benefited from the Green Deal. Like my noble friend Lord Teverson, I think the Green Deal is an excellent vehicle for being able to bring greater efficiency towards homes.
My noble friend Lord Roper and the noble Lord, Lord Grantchester, spoke about there being more than one pilot. We would rather start with what we consider the preferred option but we do not rule out there being multiple approaches simultaneously. If we have too many, it will be difficult to evaluate. We want to be sensible and see a range, if that is what is needed, but we have a preferred approach. It would be better for us as a Government to see that preferred approach dealt with first. There is nothing in the Bill to stop us having more than one approach.
I reiterate that Clause 37 is simply a spending power, required to authorise the spending of Government money. I appreciate the concern to ensure sufficient funds are available for piloting. We considered raising funds for the pilot using the capacity market powers
but rejected this approach because it would delay the start of the pilot, which we announced is expected to start next summer.
Amendments 50 and 51, from the noble Lord, Lord Grantchester, and the right reverend Prelate the Bishop of London, would require the Secretary of State to publish a strategy to reduce a stated amount of electricity demand by 2020 and 2030. While I welcome the principle behind these proposals, the Government have already published a number of documents, including on how we will meet our existing energy efficiency commitments. That is through the energy efficiency strategy which will be updated later this year, the DECC energy and emissions projections, and the Government’s response to the EDR consultation. These documents already provide a comprehensive view of Government strategy. As the pilot is designed to improve our understanding of the cost-effectiveness of EDR in relation to that of a variety of supply-side and demand-side measures, we do not consider it appropriate to set a specific EDR target.
The noble Lord, Lord Grantchester, asked about the difference in the estimates that the department has given out. The estimate of the untapped potential was revised from 92 terawatt hours to around 32 terawatt hours by 2030 because there is considerable uncertainty as to the exact level of potential for electricity demand reduction. We believe that this figure represents a much more sensible picture of what can be achieved. That analysis has also been subject to external peer review.
In conclusion, we have listened to concerns about reporting the results of the pilot and have introduced an amendment on this. Our existing legal powers already allow us to test other approaches if it becomes necessary. We believe the minimum £20 million allocated to the pilot is sufficient to support a range of projects in different sectors in these difficult times. We already have an energy efficiency strategy, which will be updated shortly. I hope that my noble friend Lord Roper, the noble Lord, Lord Grantchester, and the right reverend Prelate the Bishop of London will agree to withdraw their amendments. I beg to move the amendment that stands in my name.
