Why EVs Won't Crash the Electric Grid (msn.com) 418

"If everyone has an electric car, will the electric grid be able to support all those cars being recharged?"

That's the question being answered this week in the Washington Post's "Climate Coach" newsletter: We can already see a preview of our electric future in Norway, one of the countries with the highest share of EVs. More than 90 percent of new cars sold in the country were plug-in electric, according to the latest data, from May. More than 20 percent of the country's overall vehicle fleet is electric, a share expected to rise to one-third by 2025. So far, the grid has essentially shrugged it off. "We haven't seen any issue of the grid collapsing," says Anne Nysæther, a managing director at Elvia, a utility serving Oslo and the surrounding areas with the nation's largest concentration of EVs. The country, now almost entirely powered by renewables, has easily met the extra demand from EVs while slashing greenhouse gas emissions. That's good, because Norway will ban all new petrol and diesel cars by 2025...

To electrify everything — all these expected EVs, heat pumps and other big power draws — [the U.S.] will need to start building up our grid, according to Jesse Jenkins, an energy modeling and engineering expert at Princeton University. The United States must at least double its electricity supply by 2050, while stringing up 75,000 miles of new high-voltage lines by 2035, the equivalent of 15 round trips from Los Angeles to New York City, and connect new wind and solar generation to the grid. That sounds like a lot. But something like this has already been done. From the 1970s to the 1990s, the U.S. built new transmission capacity at a speed close to what is required today, writes Jenkins in Mother Jones, even as electricity demand grew.

    It's important to note just what exactly powers Norway that gives it such a large amount of power from renewables - to see how reproducible that is the the U.S.

    In 2021, Norway was powered 91.5% by Hydro power. [statista.com]

    It's important to note that unlike wind or solar, hydro power is constant.

    What does that mean for the U.S.? If you want to end up with the grid shrugging off EV's, better start building out lots more nuclear supply for constant load support - because lots and lots of people are going to be charging cars overnight, where solar doesn't help and wind may not provide much for weeks at a time.

        Ok, fine for Norway... how about Sweden or Denmark? ohh, they are "rich" too? and how about Spain and Portugal? they aren't rich, yet they modernized their electrical grid! It was funded by taxes on electrical prices. electricity is not cheap there, but never was, as they were dependent of external energy (coal and oil), but now they are less dependent and while the rest of Europe had huge prices increase due to the Ukraine way, both Portugal and Spain manage to keep their electrical prices from skyrocket. Their cost per kWh have been dropping from 20 years already, only increasing due to the war... but again, increasing less than the rest of the Europe, where also most of the countries had a more or less stable kWh price in the last 20 years

        Indeed, it should be much easier to build a strong, robust grid in California since it will serve far more people per kilometre of powerline. Yes, the powerlines will need to be higher voltage and/or have more cables than in Norway due to the higher density but you can serve seven times the people with it and it will definitely not cost seven times the price to build it.

        Since California has roughly the same GDP per capita as Norway there is no reason why California could not have a power grid at least as robust, if not better than Norway's due to the benefits of density and economies of scale. The difference may be that Norway has long dark winters that need light and heating so reliable electrical power is a must.

          Nope. Norway gets its electricity mainly from hydro (~91.5% in 2021). Hydro provides baseload, or if you prefer, it doesn't rely as much as solar/wind on external conditions (sun for solar, wind for. turbines). You can have that much hydropower only under very specific conditions (geographical ones mainly).

            Regardless of which electricity generation method is used, there will be a shift in spending away from gasoline and on to electricity distribution and generation. This shift will happen over a long period of time, and should allow the grid to gradually improve.

            Nuclear is much harder to build incrementally than renewables. I started out with a solar PV 6.5 kW system in 2010, increased the capacity to 9.4 kWh in 2012, and now in 2023 I'm at 20.6 kW. All the original 28 panels are still there. But now there is

            The problem with a nuclear heavy grid is that it can't react very well to demand. Hydro can, and some other renewables can.

            When everyone gets home from work and plugs in, you see a massive spike in demand. You will have to have fossil fuel plants on standby to meet it.

            Or you can shape demand with pricing. Europe does it quite successfully with EV charging. It also helps keep the price of electricity less volatile, which businesses love.

Plus the extra people would be demanding water to drink and use for crops and all that, making the situation even worse.

            Each system generates approximately the same amount of energy on any given day. Some days, the southeast produces more, others the northwest.

      I'd expect that EVs may actually help California. EVs are time-shiftable load that can charge whenever there is excess power, and stop charging whenever demand is high. So they won't contribute significantly to demand during the hours when the grid is overstrained and rolling blackouts are needed to balance consumption, but they will take revenue from gas stations and the petroleum industry and deliver it to the grid operators to fund needed buildout.
      • EVs will help California except when there are forest fires that require mass evacuation and power grid blackouts to avoid setting off more fires at the same time. We need to build adequate power and energy systems to meet all demands under the worst circumstances, inexpensively, not the average demand in average cases.

        Seriously, people are looking at this like you should calculate demand based on the average. But there's already case history on how to sort this out, from the telecommunications industry.

    People that aren't as familiar with EVs might not realize it, but most people charge their cars overnight at home. They don't use fast chargers on the highway, they use level 2 chargers at home.

    The good thing about that is that's when power consumption in general is lowest so we have a whole bunch of excess capacity.

    The bad thing is that cars/charging stations have to be configured to charge at that time and not when the driver gets home at 6PM when power consumption is the greatest.

    It's a quick and easy process, but it's something that will need to be made easier if we want to keep the grid stable

    • Even more, as we move more into renewables that have variable output, EVs really need to adjust their charging dynamically, charging not just at night, but whenever there is excess capacity. In a solar-heavy grid, that will actually be early in the day, when there's plenty of sun but the full heat is still building. In a wind-heavy grid, it can be any time of day or night, though many regions (especially coastal regions) have daily patterns.

It is largely driven by a political debate dominated by an elite that both wants to protect its own interests and lifestyle and doesn't trust the rest of us to make adult decisions.

      The energy demand is from the proletariat masses, and it necesarily always increases. I see your idea is that there should be an "elite" group of "adults" who will dictate to us what we "need". What do you envision your rank will be in the Party, Comrade?

  • TFS says Norway is just fine. No problems. But then the US will have to upgrade our system. If we are to take the example of Norway to heart (Why else did it lead the story?), then we should be just fine sitting here with our thumbs up our butts.

    Scandinavian peninsula has a very unique geographic pattern, where it's salty Atlantic Ocean on one side, mountain range near the ocean granting a significant and stable rain pattern over the mountains, and it goes slowly down into flatlands and finally Gulf of Bothnia and Baltic Sea.

    This ensures that Norway (and to a lesser extent Sweden) has the following in massive excess compared to anywhere else in the world:

    1. Dammable rivers with large height differentials over short distances.
    2. Natural reservoirs on those rivers that can be used to store water for later - effectively a cheap natural gravity battery with massive total capacity.
    3. Highly profitable grid interconnects going from southern Norway to Denmark (read below to understand why).

    This leads to Norway being able to do pretty much any stupid shit it wants with electricity except for one thing. It cannot harm its relationship with Swedish grid operator. Because one problem with that geography is that Norway has no meaningful way to move electricity over long ranges in North-South direction within its borders, only East-West. So what they do is they have two national grids that aren't actually meaningfully connected to one another. What they do is connect to Swedish flatlands in the East near Gulf of Bothia/Baltic Sea, and then move electricity within Swedish grid in North-South direction.

    This is why when Norway did some really amazingly stupid shit with their dam management last year due to them guaranteeing Danish electric grid stability, electricity prices in Oslo were some of the most expensive in Europe with something like 500 EUR per megawatt/hour spot prices while in Kirkenes, they were paying something like 20 EUR per megawatt/hour. When they realised they fucked up, they promptly adjusted their water management strategy with higher backup storage for their own grid security, so this is unlikely to repeat into the next year.

    Basically, their grid is almost entirely idiot proof. They have so much overbuilt hydro with natural (and partially artificial) reservoirs that their base power is almost 100% flexible and can start and stop rapidly and can store massive amounts of energy in the natural gravity battery they have. And they've been using this alongside Swedes to absolutely rob Danes on both electricity costs and transit fees. Beggars can't be choosers, so Danes export de facto cheap/free electricity when their wind power is up, and import incredibly expensive electricity when its down. The other option is to let their grid go into full blackout every time wind is out, so they have exactly zero choice. This was very visible a couple of years ago when Swedish grid operator went full Darth Vader on them and told them they're trebling transit costs because what other choice do you have but to pay. But this also means that their interconnects are incredibly profitable money printers, so their throughput is massive (and therefore expensive) while remaining highly profitable because Danes will pay whatever they have to pay.

    But there's one problem: There are no other locations on this planet that have this sort of geography. If you go to Norway for lessons on "how to do electric grid" and attempt to export this knowledge, you'll fail miserably because you won't have nearly 100% hydro based grid with massive natural gravity batteries across the entirety of the grid and a neighbor that is begging for you to build as many interconnects as you can because you're the only one who can unfuck their fucked up grid. Which means that solutions that work there are utterly useless everywhere else.

  • Norway has about 5.4 million people. That population would make it one of the least populated states in the US. This is not a great comparison, of course a place with such a small population can generate a high percentage of their energy with renewables. More than one US state has regular brownouts in the Summer if too many people run air conditioners. This is not realistic for the US where we have a much higher population.
  • Norway not only had an over capacity of electricity, but over 95% is hydropower. This is base-load that is available on demand AND more than 75% of that can be ramped up/down without any real issues. IOW, Norway has the PERFECT situation in that they are pre-built for this.

    OTOH, multiple papers have been written on America's ability to move our road-based transportation over to EVs. First one I read was clear back in the 80s. Back then, our grid (wiring), along with power supply (which was ~80% fossil fue
    • Just accept it, buddy. There was a time when the United States would have been up to this challenge. That time has passed.

Make sure your code does nothing gracefully.
