I feel like you don’t know what typical load curves look like it you think the peak is in the middle of the day.
There's times when I need to charge my car on a trip during the day, but yes I intentionally charge it overnight because I have an electric rate that is extremely cheap from 11pm to 7am. It costs me like 10-20% of what it would during the day depending on if its summer or winter months. This is what I set on my charging station, it will not turn on until 11pm unless I override it. You can easily set the same thing on your car.
Yes, see my edit. Any electric vehicle almost certainly has the same setting in case your charger doesn't.
Connectivity to the power supplier to start/stop charging times work. However I don’t think a majority of the country does that.
some do, others are controlled by a hand, usually connected to a human being, that decides when to plug the car in
This is Georgia Power's electric vehicle rate you can sign up for. It generally doesn't make sense to switch to it unless you have a full EV that you charge a couple of times a month at home which adds probably 25-50% of an increase to your kWh total. Super off-peak is 11pm to 7am all year.
g8r it seems like all you do is come in here and be a chicken little because the electric utilities (or ISOs) are putting out these pearl clutching messages about how will we meet this demand. I've been hearing the same shit since I left college and started working in transmission SCADA. Since then all I've heard is the same naysaying and just see utilities constantly impede any progress and drag their feet. this is a human problem, not an engineering one. i dont feel bad one bit nor should anyone else, utilities are ran by some of the biggest degenerates in the country and will be brought along kicking and screaming.
It’s a moving target we could never understand, apparently. ‘Industry’ folks out here focused on the limitations and killing progress out of fear when they should be spending their brainpower on how to move forward.
Typical system peaks are in the morning and late afternoon coinciding with people getting up and ready for work and people getting home.
If you don’t think capacity issues we currently have won’t be exacerbated by wide scale ev adoption I don’t know what to tell you. Also if you don’t think that adoption won’t drive up electric rates across the board you are naive. I do work in the electric distribution industry but not for an IOU or a Muni.
How many people (assuming the car or charger is not programmable) are going out at 10 pm to plug up their car?
People get gas on the way to work and the way home, during peak energy hours. That’s not how EV works. We definitely need more capacity. What you’re purposely failing to acknowledge is that in the short term the extra load demand is coming when the system currently has additional capacity.
What is it? If you’re talking the charging equipment, then your argument is misguided. The car almost certainly is. The amount of non-programmable EVs in daily use is and will grow to be even more insignificant.
From October through May, it's 7am to 11pm. From June through September (summer months) it's 7am to 2pm. 2pm to 7pm during those months is the super on-peak time. The normal non-time-of-use rate changes based on how many kWh you consume during part of the year, if you go over a certain amount during those months then you pay more per kWh. Most home chargers are level 2, which requires 240V hookup and usually a circuit that can handle 40-50 amps. It pulls somewhere around 6 to 7kW during charging.
I didn’t read whatever was linked earlier, but I don’t even understand what he’s trying to argue here. Like no shit demand is going t change, so let’s evolve our systems. That’s how the world works.
I am trying to say that there is already an issue with capacity without added load and there are generators going offline due to age/regulations that will add to this shortfall. These aging facilities are not being replaced fast enough either by more acceptable generation like nuke.
Not saying that. But the push for ev needs to accompany the construction of dispatchable generation facilities. However nuke take decades to build and it is a massive financial risk to build fossil fuel generation due to potential down the road legislation. In the short term 10-20 years there needs to be some assurances by the government to the generators that they won’t be bankrupted by unforeseen regulation.
g8r are you under the impression that some switch was flipped and like 25% of all non-EV car drivers will suddenly purchase a EV this year? There has been increasing EV adoption, it's not occurring at anywhere near the pace where that alone is going to cause brown outs this summer.
Oh hell yes, give me some of that "actually the government enacting regulations is why our energy usage isn't being met by producers." It's not like the fucking wild west of Texas and ERCOT's extremely unregulated market caused people to not want to invest their own money to improve the grid and instead seek just maximum profit over everything else.
I am concerned about the adoption in the next 5-10 years along with general increases in energy consumption that will occur at the same time existing generation facilities will go offline.
It’s not even regulation he’s fretting about, it’s theoretical regulation, as if regulation that cripples power production would actually survive the rule making process
Tbh every utility company does this, it’s just that texas thinks they’re special and is on their own little island of power.
So what will take the place of fossil fuels? Please don’t say solar/wind because that ain’t happening either.
I will tell you that power suppliers are making decisions today on 100+ million dollar refurbish/replacement based on potential danger of stranded cost due to future potential legislation.
My EV charging plan with PG&E has peak rates 4-9pm, with lowest midnight-3pm. Not hard to figure out how to program the car to be charged during low rate times, just plug in the car when you get home and forget about it. PG&E's generation is 85% nuclear/wind/solar/hydroelectric and only 15% natural gas, so it's pretty clean. this shit is doable
I don’t have a good answer for that since generation is out of my wheelhouse, but surely you recognize the folly of calling for more nuke generation when you’re talking a 5-10 year time scale — it would probably take that amount of time just to get a location approved. The time to build more nuke was 30 years ago.
only 2300 sq ft but we have 2 Air conditioners. So Cal edison electric rates are just off the charts and the AC has to run non stop over half the year. We're moving in August though so wont have to deal with it much longer.
This is a specific electricity usage plan you can sign up for, this is not the normal electric plan you'd get when you sign up for service unless you request it. You'd only sign up for this kind of plan if you have a EV that would add a ton of kWhs to your bill per month.
