My question has always been....If the majority of vehicles become EV, where is all the electricity going to come from?
A friend of mine is a retired Arizona Public Service (APS) lineman. He lives on a cul-de-sac with 6 homes. He said if everyone on the cul-de-sac drove an EV, the local infrastructure could not handle the load. He doesn't believe the nation's electrical infrastructure can handle the demand if EVs become the majority of the vehicles on the road.
Also with the shutting down of a lot of coal and gas fired power plants there is going to be a shortage of electricity. Wind & solar can't produce enough to meet the demand.
While EVs becoming the majority of the vehicles on the road is a ways down the road it's something to think about how we generate the power to charge them.
Yah I’m sure it will take some adjustments. Utilities are projecting that if every personal vehicle on the road was to magically become electric overnight the additional load on the grid would go up about 19 to 22 percent. But it won’t happen overnight. More like 3 or 4 decades. So utilities project 1/2 to 1 percent a year depending on the area.
As far as charging in a neighbourhood. The average 240 volt home charger draws less than a stove 27 - 32 amps. Or 6 to 8 Kw. It wouldn’t be much different than everybody sticking their Christmas turkey in at the same time.
Plus many are on time of use plans. So energy is cheaper after midnight and before 5 AM. The average North American commuter uses about 8 kw per day in their EV. We charged our commuter for years between 2 and 5 AM on a 12 amp 240 circuit. 3 Kw or so. Worked great. Plugged it in when we got home and the timers looked after the rest. Plus in the winter the preheat would come on 5 minutes before I went to work so the windows were always defrosted and it was toasty inside.
Generally speaking utilities are not concerned about it. It will be a slow transition.
