Here’s a dirty utility secret. Secondary distribution systems in your neighborhood serve 10-15 homes. The system was not designed for EV charging. It can handle four EV chargers, no more. The secondary distribution system was designed for the previous era when not everything was electric.

Thanks for that useful nugget of info. regarding secondary distribution systems. Does that apply to the south too? The reason I ask is because in the summer we have huge power demands to run the A/C, unlike the north which was meant to have natural gas helping with their extreme cold. Thus, I would assume, distributions in the south were already made for a heavy power demand.

That is kind of a national average. Your point about the heavy AC load in the south is a good one. But the system was designed for that load and I think the same general principal would apply — there’s enough extra capacity in your secondary transformer to handle a few EV chargers. Does the AC load go down much at night? Or is it constant through the 24 hour cycle?

Forty years ago, utilities were excited about EVs because they could run their baseload plants at higher output at night to charge EVs. But that was in the era of big nuke and coal plants which are gone now, so that economic motivation went away.
