Debate

Energy Grid Resilience

Contribution

I want to reinforce the point made by the noble Lord, Lord Wigley. He is right, and the Minister is right, that in the past we did indeed have resilience. In this sort of case, resilience means bringing in a large amount of extra supply at very short notice, such as could be performed at Dinorwig, the pump storage station, which I was told could bring in several gigawatts at two minutes’ notice and, furthermore, that even if it was never used, the entire system would allow other plants to run at a higher margin, with a higher inertia factor, and, therefore, provide even more resilience and effectiveness for the whole system. In this age, as we move into reliance on renewables on a massive scale, are we providing extra support of that kind—rapid resource mobilisation—which will give us the modern and reliable system that we are going to need to compete in the modern world?
