Substations will be the gas stations of the future if you want that kind of power transfer.
Imagine that you could build a small gas turbine - just a few MW - that was almost as efficient as a big multiple-100 MW turbine at a powerplant.
If the efficiency is within a few percent the transmission losses you save make it a wash, if it is the same efficiency you can save the transmission losses - and be ahead of the big turbine.
Now imagine that those turbines are only a few tons and a couple thousand cubic feet in volume so that you can put them where you want charging stations.
They could provide power to their local grid, and when an EV pulls up that wants to charge its 100kWh pack in 10 minutes - it throttles up an extra 600kW for those 10 minutes.
I'd prefer a renewable source to natural gas, but natural gas is the best that isn't renewable at the moment. Decentralized generation for the win.
The problem with that idea might be that power plants need to be run near capacity as much as possible to be profitable and to realize good efficiency. Having a turbine oversized and underutilized most of the time is going to be expensive and inefficient, as is having a large enough pipeline that can feed it's maximum demand. It might not be a practical setup.
I don't think fast charging will have daily usage by anyone. I think that a small percentage of travelers will be utilizing fast charging. It may be possible to supplement our infrastructure with batteries that can store some power for this infrequent high draw.
