Traffic congestion costs for electricity is going to get wild if we start stacking all sorts of random >= 1.5 MW demands scattered everywhere.
This is what they already are doing, the article is behind a paywall so no clue if they say it there but you can for example see this article about it: https://www.etechvolution.com/p/byd-megawatt-flash-charging-...
Supercaps are viable for this sort of short term charge and discharge. The much maligned donut labs is suspected to be a license built Nordic hybrid supercap battery model

BYD's megawatt charging does exactly that.
Tbe best part, the "large battery" uses the same battary on BYD cars. The same electric components, cooling system, etc.
