NG isn't the problem, the transmission network was built to take hugely demanding steel and aluminium smelters that (largely) don't exist anymore - hence has significant spare capacity on many routes. The exceptions to that are the critical boundary circuits which are already being reinforced to serve new interconnections, wind, and Hinkley Point if by some miracle the project is not canned by our incompetent government. There is good reason why NG are looking at putting in huge arrays of charging stations at motorway services, direct connected to the 275 and 400kV networks.
Your distro network however, that's a much nastier problem. Capacity on 33kV and below networks down to the 240 to your street is not nearly capable enough of delivering massed charging points, and especially not fast chargers en masse at similar times of day. Cramming more infrastructure into our already narrow and overcrowded streets will require absolutely bucketloads of roadworks and disruption to service that shortfall.
Too many problems, too many people. It's a land of confusion. Thanos and Zorin may, one hesitates to say, may have been right.
