My Lords, I think that I can thank both the noble Baroness and the noble Lord for supporting the regulations. They are pretty technical and complicated, but they correct perhaps inevitable imperfections in the original legislation passed in 2013.
The noble Lord, Lord Grantchester, raised a number of other more profound issues which I hope he will agree do not pertain directly to the matter in hand, but perhaps I may try to answer some of the questions that he raised. I think that his fundamental question was whether the capacity market is value for money. Using his analogy of the insurance market, the total gross premium that we have paid over the period to 2020-21 is £3.35 billion. That is the premium that we have paid to obviate the possibility of the lights going off over that period. Whether or not that is value for money, the noble Lord will have to draw his own conclusions. I think it is quite hard to assess that, except for the fact that if the lights did go off it would be a catastrophe. In the context of the British economy, that may be a premium worth paying. That is a subjective view, and he will have his own thoughts on that.
The noble Lord raised a number of other issues, to which I do not have a reply—at least, I cannot reply in the way that I would like to be able to. He asked four other questions. He answered one of them himself, fortunately, so that leaves me three other questions to address. One was: has this brought forward new investment in generation? The answer is that it has. I mentioned some in my speech. Whether it has brought forward enough is probably the question that he was asking, and he related that to the nuclear investment. I would like to think about that, if I may, and write to him afterwards. Related to that, he asked: has this brought forward new alternative capacity? I guess by that he meant wind, solar and the like. The answer has to be: yes, it has.
