My Lords, the expansion of data centres will require a significant expansion of the grid and of energy sources. In a written reply to me, the Minister indicated that, for the high-level grid, there is something like a four-year lead time for securing equipment. Furthermore, on energy sources, data centres need reliable sources of supply. Inevitably, that will mean the development of nuclear power, including small modular reactors. When will the Government get on and make a decision about the future of the small modular reactor programme?
