Interestingly, the Climate Change Committee, which has looked into this matter in great depth, considers that in the overall long-term future make-up of our energy mix, about 8 to 10 gigawatts of standby power—therm power—is likely to be required in the shape of new or existing nuclear power stations. That is about the size of the difference with an overwhelmingly renewable but variable economy, with elements of firm power backing it up.
I have mentioned that one plant only that would be included in the suggested 8 GW to 10 GW is in prospect for a start before the late 2020s, because every other proposal has fallen away. However, it is not financed and is probably not financeable by private capital. It is only part financeable by a state financer, with which we do not now want to do business. Let us be clear before we go any further: this Bill is about finding a formula to fund and build Sizewell C power station. Whatever its generic pretensions, that is the issue we should be concentrating on. Even so, getting that plant going would cover most of what the Climate Change Committee considers is the presence in the mix needed.
