My Lords, the excellent document Powering Up Britain talks about a 100% increase in national grid capacity to deliver an all-electric economy by 2050. National Grid itself talks about a much larger figure: a 200% or 300% addition in the national grid. Can the Minister guide us on which he thinks is the most reliable of those estimates? Can he also tell us how it is all to be financed and, indeed, how the planning system will be sped up so that we can achieve anywhere near that by 2050?
