Keep in mind that, at least currently, most EVs charge at home, off hours, when there's a surplus. It's not much power, on average it's less than a single 120v

Keep in mind that, at least currently, most EVs charge at home, off hours, when there's a surplus. It's not much power, on average it's less than a single 120v socket. Sadly only Tesla knows the totals, but I'd be surprised if supercharging is (on average) 1/20th of the home charging. Around 1/3rd of the Tesla owners I know have solar panels, although many of those are in California and they changed the rates to be 1/4th or less of what they were, so they no longer contribute to the grid, but instead time shift with batteries. The power production folks are lobbying for lower rates, which lowers the amount of solar that enters the grid, which increases demand for electricity, which makes more profit for the power companies. Sad.
