    It’s exactly the same. You’re adding one 30-50A circuit to residential that will be used intermittently, and primarily during off peak hours. Very, very few vehicles will need a full charge every night, and the software on the charger side typically meters in current at much less than capacity if it’s on a schedule, as the lower the current, the less heat, and less stress on the battery . Large charging stations are on par with commercial/light industrial, and we add that sort of load all the time.

    I’ve worked for power utilities for 25 years on the generation side with some on the T&D side. The planners spend a pile of time on analysis to determine where additional load and/or sources are being added and triage based on that. When old stuff is scheduled for replacement, sometimes an upgrade is warranted, sometimes not, based on that analysis.

    A lot of electrical equipment currently has long lead times. I’ve got quotes for up to 70 weeks on some stuff. It’s been a side effect of relying on dodgy suppliers overseas. It has been improving.
