Amen, at 100kW, a single Tesla charging demands the grid provide the equivalent of ONE HUNDRED homes average power. This is a ludicrous investment in Copper wire, transformers and electrical distribution equipment just to deliver in 20 minutes, what one home's wiring could provide in one hour.
Such demand for triple the speed at ONE NUNDRED TIMES THE INFRASTRUCTURE COST is not sustainable. Hence, why such fast chargers are going to have to eventually do their own energy storage on site to not place such peak demands on the grid.
