As an aside, we have so far really dropped the ball on level 1 electric vehicle chargers at offices. As solar power and EV numbers increase, it's pretty obvious that we want more cars charging during the day and fewer charging at night.
Our govt. really did a disservice to transition to EVs by slapping on a big tax to anyone even brushing against a charger at work: 120€/year
Not sure why you are being downvoted.
The absolutely largest peak is in the morning and then a smaller one in the afternoon.
So you might have a baseline like every 10 or 15 mins and then in rush hour it is every 3 or 5 mins.
humans have places to be. They shouldn't wait for transit. and they mostly won't.
City busses don’t need that much energy because as they don’t move quickly, the cargo is light, and regenerative breaking offsets stop and go.
Also, if it is a cold night and everyone leaves electric heating/heat pumps on, what happens then? Noone can get to work the next day?
Regardless most urban transformers are not going to have 15MW of overnight capacity spare even on a good day. The largest LV substations might be 30MVA in the UK at least - they won't just have half capacity suddenly free.
