120 kWh / 24h = 5000 W, not 500 Many houses in cold climates using electrical heaters will actually use at least 2-3x this energy. So yeah, 100 kW is quite st

  You're correct, my mistake. Still, that would be 20 times the average load on those homes, to charge a single vehicle. To move that power 100 feet, like from a busbar (I think, I'm not an electrician) to the charger would require a 3/0 AWG copper cable (which has a diameter of around 2 1/2", or 5.8mm). That cable costs around $2.59 a foot, or $259 to get power to that charger. That would be undersized, since I calculated it out at exactly capacity, and that price wouldn't include conduit (since the cable isn't direct burial) or installation. Multiply that by three chargers, which I'd consider to be on the very low end of what a commercial installment would need, and you have quite a high demand for power. Five hundred amps at 480V is no joke. On the plus side, all this could spur adoption of renewable energy; with enough demand for power, investors will shovel money into renewable energy faster than it can even be used.
