National Grid says "foundational technologies" like AI and quantum computing are driving power demand.
Chief executive John Pettigrew said the grid was becoming "constrained" and "bold action" was needed to create a network able to cope with "dramatically" growing demand.
"Future growth in foundational technologies like artificial intelligence and quantum computing will mean larger scale, energy-intensive computing infrastructure," Mr Pettigrew said.
so far there is no significant quanum advantage, i.e. most things you can do on a quantum computer, you can do cheaper on a regular computer. Therefor there is not much value in quantum computing. Therefor I doubt we will see a significant surge in power-use due to quantum computing in the next 10 years
