Dan Clemmensen + 1,011 September 29, 2020 Today, Oilprice Carried this article: https://oilprice.com/Energy/Energy-General/Californias-Electric-Vehicle-Dream-Has-A-Major-Problem.html The article asserts that stopping the sale of ICEs by 2035 in California will impose a large burden on the electrical grid due to EVs, and that this is a big problem. The article notes that The required EVs will increase the demand for electricity by at least 25% (true) but assumes that this will increase the peak demand by 25%. This assumption is unrealistic. Peak demand occurs in the evening, just after everybody gets home. But by 2035, many EVs may charge at work, and the EVs that charge at home do not need to charge in the evening. EVs that are at home during the day can charge then, and EVs that must charge at night can charge after the peak. Basically all EVs already have network-connected computers already, and this can easily be made mandatory or can be made very attractive for new EVs. Within one or two years the vast majority of California EVs will be network-connected. My guess is that this is already true. It is straightforward to schedule these EVs to have these EVs share information about their charging needs, and for the power company to tell each EV when to charge and at what current. The electrical rate structure can be adjusted so that EVs that honor these requests will get cheaper electricity. No new hardware is required for this. There is no need to implement "V to G" to let the EV send power back into the grid. Consider a limiting case wherein all EVs in the state must charge between the hours of midnight and 7AM. That's off-peak for sure. Most EV currently get about 4 mi/kWh, and the daily drive is about 36 mi, so each EV needs 9 kWh a day. Folks using low-end chargers can still charge in 6 hours at 1.5 kW. Folks with faster chargers will charge during their assigned times at higher rates, with the same overall effect. Sure, lots of folks drive further on average, and just about everybody occasionally drives a lot further, but these are averages, so it works out. Folks on road trips will need to charge away from home anyway, and supercharger stations will have large stationary batteries to avoid using peak electricity. Conclusion: EVs will use a lot of electricity, but basically none of it is peak electricity. 1 1 Quote Share this post Link to post Share on other sites

I suggest you are assuming a level of societal compliance, as to times to plug it in etc., that is unrealistic outside of a highly regimented society. I don't see people being that disciplined. Right now BMW for example is touting a wireless re-charge system consisting of a charging coil inside a flat mat, that the driver placed his car over when in the garage. The mat emits an AC field and the bottom of the car has a corresponding AC coupler. In effect the coupler is a transformer, with the two winding coils separated. This is a lossy system but very convenient for the rich: park it, and forget it. Is anyone going to suggest that recharge current will not be supplied until midnight? What if that BMW owner wishes to go out that evening, or depart for Vegas? No, they will rig those systems to go on automatically when the car rolls over it, just as BMW has designed the system. The idea that these owners are going to show restraint is a fallacy. Cheers. 4 Quote Share this post Link to post Share on other sites

The idea that these owners are going to show restraint is a fallacy. Cheers. I had a BMW i3 for 5.5 years. I charge at home, and I am on the PG&E's EV-A rate plan. My electricity after midnight costs less than a third of my electricity from 3:00 PM to midnight. I plugged that car in every time I arrived at home. The car's computer started charging it at 12:05 AM and could charge from empty to full before 7:00AM. Why would I choose to pay more than triple the amount I was paying? I programmed this behavior one time, and the computer did the rest. If I had an inductive mat, The car would still not start using it until after midnight. On those rare occasions that I needed to charge at other times (e.g., a long drive in the morning followed by a long drive in the evening), I had to click one virtual button to override this behavior. I now have a Tesla Model Y. It can do the same thing, but in addition it can interact with Tesla's central computer to decide when and where to charge on the basis of my planned travel. Tesla's algorithms can be easily modified to know about the need to shed load and to rotate the charging of the cars in the neighborhood. I am not assuming "societal compliance" at all. I am assuming that complying consumers will be rewarded instantly by being charged less for the electricity (or penalized for using peak electricity). Remember that this approach works when most people are "complying" most of the time. Those that need to use peak power will do so, as will those who simply do not care how much money they spend on electricity. This will include the tiny percentage of arrogant rich people who choose to use inductive chargers. You can bet that Tesla (and probably others) will find a way to fully automate the wired connection process if those inductive chargers prove to be attractive. An automated wired plug would be more expensive than an inductive mat, but would pay for itself very quickly. I'm fairly sure I could design a robotic arm that could plug in the Model Y with no modifications to the car or the charging cable at all, with a total parts cost of <$500. A production system that included modifications to the car and charger would cost less. 1 Quote Share this post Link to post Share on other sites

Calling it Commiefornia is harsh but sadly prescient. Well heres what I was saying currently most electricity is claimed to be 4x cheaper outside of California across the USA. So even at 10c/kwh the average home uses 500kwh per month averaged out over the year? So if you have gasoline cars and 10c electricity say 4 tanks a week in a small fwd suv 30$ to fill? (I only know Canadian prices for gasoline) so 120$ for fuel + 500x.10 = 50$ +120$ = 170$ gasoline and electricity. VS. 500kwh and 4x 100kwh battery charges (if not more) so 900kwh x 60c/kwh = 540$ ok let's do 30c that's a soon future = 270$ .... on what planet are you saving ? On the California @18.8c / kwh. Are they outlawing nat gas appliances? https://www.spglobal.com/marketintelligence/en/news-insights/latest-news-headlines/banning-natural-gas-is-out-electrifying-buildings-is-in-59285807 "I think that the term gas ban might not work" beyond California, said Jenna Tatum, director of the Building Electrification Initiative, a group that helps its eight-member cities advance electrification efforts. "But I think that a policy that encourages or requires all electric new construction works everywhere." Despite its influence, relatively few cities have carbon copied the Berkeley gas ban. Instead, local lawmakers are developing multiple pathways to building electrification, tailored not only to their own legal framework, but also to regional political, industry pushback and cultural differences. I googled California power prices and its average in 2019 was 16.7c kWh. And just found 19c in 2020 PG&E Delivery Rate is a charge assessed by PG&E to deliver electricity to your home or business. The PG&E delivery rate depends on your electricity usage, but is charged equally to both PCE and PG&E customers. PG&E PCIA/FF represents the Power Charge Indifference Adjustment (PCIA) and the Franchise Fee surcharge (FF).

Rob, it is my prediction that the consumers will start demanding their large appliances, e.g range, oven, fridge, clothes dryer, to run on something other than electricity. So, I predict you will soon see both gas appliances, and specialized units such as propane driving ammonia-cycle refrigerators', and both propane and nat-gas clothes dryers. The ammonia cycle has a long history in the USA. Originally developed for lakeside cottages, they ran on a small flame typically driven by kerosine. Building those to run on a smallish propane tank should be easy enough. Permanent home units would run off a typical 100-gallon propane tank (permanent installation), and those tanks can be rented from the supplier. Remember that the folks went to electricity because it was convenient (no fuel supply to worry about) and because the electricity itself was cheap. Now, with the electricity getting expensive fast, and also unreliable, I suggest you will see a big resurgence in propane and nat-gas appliances. Cheers. 2 Quote Share this post Link to post Share on other sites

Problem with ammonia units is if they leak it could kill your family; safer halocarbon alternatives won out. Flammable gas clothes dryers pose a slightly increased fire risk and require more stringent exhaust systems (you are not just blowing out Bounce-fresh humid air, you now need to deal with combustion products).

Dan - while some of what you says it true and that proper management will reduce the load there is also no doubt that the large scale switch to EVs will have a major effect on a grid that's already struggling, as I understand it, with existing demand. A major strengthening of firm supply - gas and coal plants - would be required before such a change and that would seem to defeat the purpose. Otherwise, any blackouts or brownouts would have far more serious consequences than they do now. I note, also, that your solution requires a vast expansion in charging points in just 15 years.. granted it could be done but its a major, additional cost on top of all the others required to keep the power supply on its feet in order to recharge cars. This is not an easy change, and its certainly not a cheap one. I'm glad I'm not paying for it. 1 1 Quote Share this post Link to post Share on other sites

It started from the power companies, possibly in conjunction with the appliance makers. Some subdivisions were, I think, all electric in the fifties. My Auburn home was all electric. It was rural so no gas plus a moderate climate so a heat pump combined with the air conditioning worked great. Does anyone have an idea how many heat pumps are used now. Mine was about 1976.

Thanks ... I'm used to nat gas stove , dryers, water tank and furnace (even tho my current ones are electric + induction....hot water tank and furnace is still nat gas but after all this carbon tax and customer charge debating electric replacement when it fails) . Found a chart the other day on Canadian Nat gas production 2019 15.7BCF average vs 15.3BCF average for 2020. Using simple math canada exports net 4bcf to USA so at close to 11BCF local demand if we had 10x the population like USA we'd use 110BCF vs US at closer to 90BCF.

For these chargers, the "major expansion" you speak of just happens as EV sales expand. (i.e., one EV, one home charger). This (and any other shift to using more electricity) can require heavy-up of the neighborhood distributions networks, but most neighborhoods won't be affected because they already comfortably handle the peak. We are going to have a bigger problem with increased installation and use of air conditioning as the temperatures rise. For other charging points, EV manufacturers have a vested interest in adding away-from-home charging points as EV sales expand. Tesla is the most obvious example of this, but other EV manufacturers are partnering with charging station companies to expand the nets. Given a 15-year timeline, I doubt there will be problem.

You design to MAXIMUMS!!!!! The system is sized to provide for the peak power demand, which is in August. Those two holiday periods will be not on top of a peak. In California, if you are on a time-varying rate plan, those days get off-peak rates, and drivers have no incentive to defer charging until after midnight. Therefore, during those holidays the demand will be smoothed our over the entire 24 hours. I think we might have problems on Memorial Day and Labor Day, though. We have until 2035 to solve those problems. The additional air conditioning load as the temperatures increase are a much bigger problem. Quote Share this post Link to post Share on other sites

The state currently has no debt that I am aware of associated with power generation or the grid. we have investor-owned utilities. We do have a mess on our hands as the for-profit companies do what all for-profit companies do: try to privatize the profits and socialize the losses. For natural gas, the power companies got slightly ahead of themselves on decomissioning some NG plants before getting the big new battery up and running. This caused the one and only failure to meet demand in the last 15 years. 1 Quote Share this post Link to post Share on other sites

The reality is that the utility just spends the money it chooses to, with the permission of the state and the state taxes the consumer through add on taxes on the utility bills. The prices just keep rising for no apparent reason even if the actual usage diminishes due to better insulation, lighting and appliances. The price will be paid by electric vehicles also. Soon their owners will be taxed by the number of miles they drive. Soon people move elsewhere. It would be interesting to see how an independent solar building owner or home would do if that caught on. I predict they will be heavily taxed using some green rationale. If I owned such a home I would try to power an electric vehicle with a carport or some other solar system IF the price, including installation and maintenance was below other options in the long run and if I were young.

Enthalpic + 1,496 September 30, 2020 (edited) Will a gasoline pump work without electricity, both the one in your car and the one at the fuel station? How about a forced-air natural gas furnace for your home? Everything needs electricity - not everything needs petroleum fuel. Petroleum fuel free vehicles exist. Unless you hand crank or pull start your car it already uses battery storage and a electric starter. Edited September 30, 2020 by Enthalpic Quote Share this post Link to post Share on other sites

I mean, if the "new" systems are seen to be even somewhat borderline in their ability to handle any and all peak demands, wouldn't it make sense to just keep some of the old system as backup? My understanding is that NG plants can be started up in very short order to handle such types of situations. Is that correct, or am I missing something?
