My Lords, I wanted to make a few comments about how such an obligation might work. Of course, I completely concur with noble Lords who have spoken already; this is clearly a probing amendment, and a lot of work will need to be done to think through how it might work in practice.
The one thing that I would like to illustrate is that, on the fuel disclosure requirements that we currently have, 12 suppliers are required to report and many of those report very low carbon intensities because they are specifically green suppliers. Of those that are mixed suppliers, there is a very great difference between them; at the top end of the scale, we have Scottish Power in 2011, whose CO2 intensity was 580 grams per kilowatt hour. At the bottom end of the scale you have EDF Energy, with 253 grams per kilowatt hour. Obviously, that is because the plant self-serves to those supply companies; they are both energy generators and energy suppliers, so they choose to use their own power. It would be hard to imagine giving one figure that they should all meet, but an obligation might be that they should demonstrate an improvement over time by percentage per annum on their current levels, as recorded over the past six years.
There are a couple of reasons why that idea might be a good one to explore. We know that there is an issue among independent generators, which fear that they will not be able to gain access to the market because of self-serving—the tendency to use your own plant and be vertically integrated. If they were required to shift to a low-carbon footprint and intensity, they would have an incentive to find those independent generators that can generate low-carbon electricity and reduce their footprint. That could knock off quite a few issues in one, if we looked at it in detail.
Another thing to commend that idea is that the measures in the Bill are designed to bring forward investment, but nothing is there to compel anybody to come forward. You can set up a CFD strike price and offer these contracts, but if no one wants to bother getting them they can simply carry on with business as usual. If they had this obligation, it would create a great incentive to find those CFDs, apply for them and come forward. The alternative is simply to keep offering higher and higher strike prices until the carrot becomes so attractive that they have to come forward. So it is a good insurance policy for the Bill, providing a way for the Government to link those targets that they propose to set in 2016 with an actual mechanism for delivery. Let us be honest: a target set by the Government to deliver carbon intensity of any value will be delivered only if you find a way for the commercial operators in the market to deliver it. This is one way, and it has potential supplementary benefits in giving independents confidence that their products will have a market.
I hope that we can look at this issue. As my noble friend has mentioned, this is a probing amendment and lots of the details have to be worked out, but it
would be encouraging to hear some positive signals from the Government that we might be able to continue the discussion.
