The issue is a little more nuanced than that. Most buildings can only install a few EV chargers before they need to upgrade the mains, and if that needs to be done, the transformers likely aren’t adequate, and the local grid may not be able to withstand it as well.
The owners costs ends at the transformers, taxpayers and the energy corp are in for the rest, and until the energy corp upgrades the grid and transformers, building owners can only do so much.
If the infrastructure can't handle it, then upgrade the fucking infrastructure! Politicians will fall at voters' feet to build new roads, highways, etc., but when it comes to the green energy transition, there's no problem too minuscule to be ignored!
I'll happily admit that there are going to be many issues in the green energy transition; we should acknowledge them, but we should also strive to address them, rather than throwing our hands up in the air and idly promulgating the status quo.
Switching from one type of car to another isn't a green transition. Car production still creates enormous co2 emissions, paving everything for cars makes heat islands, tires produce piles of particulate pollution, and so on. Fixing the car pollution problem means moving to other forms of transportation, not just slightly-less-bad automobiles.
Amen. Don't have to worry about the house, neighborhood, or city infrastructures supporting your EV if your EV is an ebike that can plug into a standard outlet in your living room, or wherever you keep it. Or if you can just walk a quarter mile and hop on a light rail. Or if instead of driving a Ford, you just use your Chevrolegs. Of course, this does also require development patterns to support it, i.e. roads that aren't fucking death traps for anyone outside a car and stuff being close enough together that you can actually get to it in a reasonable amount of time, but hey, there are also non-car-related reasons we should be doing those things too.
Hehe, reminds me of a similar joke in French, "B-M-double-pieds" (B-M-double-feet, for BMW).
They are upgrading it, as people need it and as fast as they can ahead of planned upgrades.
There shortages on parts, so most are being done as required, but to think it’s not being upgraded (in most places, local bullshit aside) is just pure ignorance.
I'm sure people are trying to address the problems, I'm not saying that's not happening. What I find maddening however is the double standard between how issues are handled when it's fossil fuels vs. green energy. Every tiny issue with green energy is breathlessly amplified, while there's no shortage of idiotic solutions to resolve issues in carbon-based energy infrastructure.
It's this atmosphere that I'm trying to raise awareness of and change!
"The grid can't handle it" is a bullshit argument that is easy to sell to people who want to keep their IC cars. The difference between highest demand and lowest demand in Ontario this week was 7000MW, if everyone charges their car at night there is power available AND it helps increase the base load which is good for the gird operators.
Even individual buildings may not need to upgrade their main service even with rapid chargers, the operators just need to keep in mind not to run the oven, dryer, AC and car charger at the same time.

Yes the power plants can pump out enough, but not all transfer stations are able to handle the load, each individual hub, may not be able to handle the load.
It’s far more nuanced than this even, but don’t believe everything everyone is selling you, everyone has an agenda and no one is going to tell you the entire truth.
If an entire block suddenly goes EV one night the infrastructure isn’t there, it’s slowly being updated which you don’t see, but there’s issues out there.
New Brunswick had a program in the 1970s/80s to get people to switch to electric home heating due to the oil shocks. That was far more ambitious than what is being proposed here.
Edit. I was curious, so I looked up recent numbers for home heating in NB, as it's the area I'm most familiar with.
From 2000-2020, the number of residences increased by 46,000 (285,000 to 331,000). Overall, 72% of which are detached houses. The market share of electric heating went from 57% overall to 79% in those 22 years.
New generation was limited to ~400MW nameplate of wind and one 250MW combined cycle natural gas plant, while several older coal/heavy oil units were mothballed, so overall output hardly changed.
There are a lot of places that grew a lot faster. Yet, the power stayed on.
Moot point, nowhere will suddenly switch to electric vehicles overnight.
Everyone in the burbs run their AC full tilt all summer and the grid holds up just fine. An EV charger used overnight, when your AC runs less, would present no more of a load than the daytime high usage. Stop pushing anti-electrification bullshit, or move to Alberta, they love that shit.
This is no different from the widespread adoption of electric clothes dryers, water heaters or domestic home air conditioning. Electrical distribution is never static.
Also, on 2400w an EV can charge a significantly large amount overnight. You mightn't need a charge point in the first place.
2400W x number of occupants is still some series draw on their main panel.
Their point still stands that their mains would need an upgrade.
Electrician here, no it would not need to upgrade your panel to add a charger. If you have an intermittent load, like a car charger, you can add it on to your panel provided you don't run it along with your other high power, intermittent loads (clothes dryer, oven).
I hadn't considered that aspect, thank you for the information!
