Question from Duane Jonlin:
If we were to start providing for future large-scale EV charging infrastructure in new and renovated buildings, what’s a reasonable electric load per 100 spaces to assume? It would be different for apartment buildings, office buildings, retail & entertainment, hospitals, schools…
Would we assume that the great majority of drivers would charge up overnight at home, and not really need charging at the office or clinic or movie theater? In that case, we’d just assume a small proportion of cars (5% or less) would be charging at commercial establishments at any one time, but that a large proportion (50% or more) would need charging sometime between 7:00 PM and 7:00 AM at an apartment building.
In the garages, it doesn’t seem reasonable to provide for outlets at every single parking space. Maybe there’d be a few short-term parking spots for those cars that needed active charging (in case someone needed to drive to an appointment that morning), and a larger number of parking spots for people who only wanted to have their cars charged sometime before they left the office at 5:00…
But I digress. I’m really trying to figure out what exactly I will be asking City Light to provide for new buildings, and I don’t want to operate under assumptions that wouldn’t bear up under questioning at a City Council meeting! For, say, a 200-car office building garage, how much charging power will we need 10 years from now?
