Renewable Heat Incentive Scheme Regulations 2011

My Lords, I, too, thank the noble Baroness for her explanation of this measure, which takes up many pages, and congratulate her on taking up the cudgels for the Department of Energy and Climate Change. I have a mild interest since I have a farm, where there is obviously scope for generating various kinds of renewable energy. I was interested to hear the noble Baroness say that the plan was to reduce the periodic support payments for large biomass operations, which reminded me of something that I saw recently on a BBC web page. Perhaps the Minister can write to me if she does not have a ready answer for this. The Scottish Government have devolved powers for renewable energy, and seem to be holding a consultation on reducing the ROCs on large biomass generation because they want to devote them to marine energy. However, does large-scale biomass qualify for ROCs as well as periodic support payments? What power do the Scottish Executive have over renewables obligation certificates? Can they allocate them up and down at their own will, or is the allocation of ROCs still a UK power?
