I get it! Your post solidifies what I’m saying about the demand increases.
One point I did not mention is that in Britain they way that EV charging is being managed is that all new EV chargers have to have its own smart meter that has the ability to be turned on or off remotely. This allows the power dispatching centers to control when and how fast EV charging can be brought on line. That’s one way to keep the load demand within the frequency demand response of the ACE equation. The diversity a lot of these engineers speak of still incorporates a “smart” grid wherein the batteries in electric cars are used to help support the grid when generation resources are low.
I also want to be clear here, if people want an electric car because they think they are trick I have no issue with that, that’s an individual choice. What I have a problem with is when it’s put out that EV’s are zero emission vehicles, and that the current grid infrastructure can handle this load increase. Again I had these discussions with EV interest groups about making the place where I worked electric car friendly, and I as the supervisor over the grid control center was brought in as the subject matter expert. When I started asking the logical questions about how the existing switchgear in the car parks was going to have to be upgraded by 80% to handle these loads and why, I was then attacked for being anti EV. I told this one person that these are the laws of physics and electrical theory, those things don’t have feelings, people way smarter than me figured all this stuff out, people like; Volta, Ampere, Kirchhoff, Westinghouse and most of all Nikola Tesla, I’m just telling you THE facts, not my facts, THE facts.
Lastly, I was thinking last night how I would go about expanding the grid to handle this load increase and realized I left something out of my previous mention about fault studies and fault duties, about the only way to handle the increase in fault duty is to further break the distribution substations out into many more stations with the associated relay coordination, transfer trip schemes that utilize pilot wire comms as well as SPS / RAS (special protection schemes / remedial action schemes) to help manage fault duty. This would also involve breaking the sub transmission and transmission systems out into isolated systems as all that supply would be subject to the overall fault duty, these systems could be tied together in certain very limited scenarios for redundancy in the N-1, N-2, N-3 etc..planning.
EVs can be easily charged overnight assuming you charge at home. That is when grid is not overloaded and consumption goes down.
Very easy to influence behavior of people charging.
Like in MD they offer almost 3 different programs for you and you can participate in all 3 at the same time.
If you charge during off peak ours basically 9pm-7am or anytime on weekend you get 50% off on your car charging consumption.
If you charge 90% of your time during off peak they give you $50 a year reward.
If you connect your electric charger to local utility and they control you charging basically 12am-7am you get additional $10 bill credit.
In all these cases you can override and charge whenever you want but in 99% of cases that would fit avg driver. After all these incentives you are basically paying $0.05 -$0.06 per kWh vs $0.40 at charging stations.
Now when you talk about public transportation, commercial fleet, police vehicles and so on that will drive the consumption through the roof.
Also knowing our government they will incentivize something to the point when it doesn't make any sense and after start taxing the shit out of you.
Right now EVs do not contribute anything to road infrastructure and they are heavy as hell. ICE vehicle do that at the pump. Some states trying to fix it by charging higher registration fees for EVs.
What I expect is that soon owning EV will not bring you any savings vs GAS, they are more expensive to begin with, Rivian for example is an energy hog and with increase demand on the grid the price of electricity will go up even more. No one is building new Nukes it is just not economically feasible, old Nukes will start retiring since they are all 50-60 years old. And new generation AKA solar panels and wind is a total joke. Solar panel performance degrades like crazy plus you need to clean those panels from dust and dirt, if not their efficiency drops even more.
Except for cool electronics, being "environmentally friendly", ease of maintenance there is no point owning EV. You can get 2 Priuses for the price of one Tesla and those provide same fuel savings.
