    Or to put it another way, the grid is becoming the most important bottleneck when it’s sunny, and that will be an opportunity for technologies that take advantage of cheap solar but somehow avoid the bottleneck.

    Perhaps countries with worse grids (like Japan) noticed the bottleneck first? I think in the US there’s been an assumption that building enough power lines is doable.

      Ultimately, it would be better for distributed storage solutions to be subsidized as much if not more than solar itself, as we still haven't solved that nasty 'sun goes down at night' problem.

        Which is why I'm so excited by grid-scale batteries becoming rapidly cheaper! Especially if space is not a concern, sodium ion batteries are significantly cheaper than lithium batteries.

          Part of the reason I want them decentralized is that having them localized at point of use reduces transmission losses.

          Having 1/10 of homes in the USA having say a 10kwh battery, which costs about $4k retail provides an overall capacity of 150GWh, in a way that makes it less prone to becoming useless in partial grid failure situations...and the tech is ready today.

            There is a utility in Vermont doing it, but it’s more about reliability in rural areas. I expect that will be the main application and utility-scale batteries will make more sense for cities.

            You make a good point. I can definitely imagine some apartment towers benefitting from a battery installation.

              Maybe a rule along the lines 'minimum 5 kwh battery installed in electric panel' for new builds as a sort of brownout/blackout insurance, even without onsite generation.

              That would potentially add $4k to a new build, but that's like a drop in the bucket.

                $4k would indeed be a drop in the bucket, especially if you want to pair ongoing forever "brownout/blackout insurance" cost as the stick that goes with the carrot.

              If it’s for pumped hydro storage you can just be using the dams to create artificial recreational lakes and streams. It wouldn’t need to be on existing rivers.

      It might be doable in theory, but requires a lot of investments. Investments that are not necessarily done (everywhere), and when the budget is made available, it is often late. To the point that it will take several years if not longer before the grid has been upgraded.

      In fact, it is interesting when you say that Japan has a worse grid when I know the US to have the reputation of having a power grid that has lacked critical investments in its core infrastructure for decades. Here in the Netherlands we already struggle to keep up. And I know for a fact that our grid has been maintained to a higher standard compared to that in many (most) places in the US. Outages here for example are extremely rare compared to the US. To the point that most people will struggle to remember when the power went out for the last time. When I went to look it up I also compared it to Japan which is interesting as a lower score here is better. For reference, it is showing the System Average Interruption Duration Index (SAIDI), which measures the average outage time per customer per year.

      When I went to investigate a bit more, I found that the Japanese grid is actually not known to be worse. In fact, it is known for its reliability (shown in the SAIDI score, amongst other things). So maybe you were thinking of a different country, but also there, I doubt it is another Western country. All sources I come across seem to indicate that the US is lagging behind when it concerns the powergrid.

          Japan’s grid reliability, as I mentioned in my earlier comment (with the SAIDI data), contrasts with the unique challenges of scaling or transitioning energy sources, which are not the same as maintaining a basic functioning grid.

          Additionally, I really want to point out that relying solely on one post from Tildes may not provide a full picture. Certainly not when referencing the US situation. Even more so, as it seems you have some unchecked assumptions about the US situation.

          I provided a variety of articles and sources that actually are applicable to the US and the unique challenges the US is facing. So I very much would like to invite you to check them out for yourself.

        Pretty sure the US grid is not so great relatively. I remember one of the key reasons being that many European countries rebuilt practically from scratch after WWIi due to damage from bombing campaigns. The US never had this so....we still have wires on wooden poles for transmission in some places.

        Other developing/recently developed countries basically skipped a few "versions" and basically started at v3.0 instead of 1.0 because that was the most cost effective method at the time. They went from "nothing" to underground eartquake proof grids rather than above ground wires on sticks.

        Size also matters, smaller countries can have mostly underground set ups, whereas larger countries pretty much have to use above ground towers and wires for long range transmission due to cost.

          Wires on poles can also be easier to rebuild after a disaster which is part of why they're the default in Japan.

        As I said, yes the Netherlands is struggling, but it really is not the same as in the US. Part of the struggle we are dealing with is upgrading the grid while maintaining the same high standard. If we would use the same standards as the US we suddenly would have much more capacity out of the blue.

    I am off grid, with solar and batteries, and I gotta say... I thought it would be much harder for some reason. I thought there would be a lot more inconveniences but it is really not that different. The only one that sucks is not being able to run my air conditioner past 6pm in July but other than that it's great. I could technically, but the battery would die and I try to only use 2kwh in the night time.

Lucky for me, I rented this place from a battery engineer so it is his job and also his hobby to build electrical shit. He sold the property 6 months ago to my next door neighbors, who are construction workers. There is always something being built, upgraded, worked on.. I would definitely have to hire someone if I ever get a property of my own. It is cool being around people who know what they're doing! My other neighbor is working on a gray water reclamation system that repurposes the water from his outdoor shower into a little fountain for the wildlife to drink from (I'm guessing it will be mostly birds and frogs though we do have foxes, raccoons, and coyotes). It will use plants as a filter. Off grid stuff is neat.

        It's a regular window unit, the kind that's on wheels and easy to set up with any window. It runs at abput 1000 watts. There are 6 other houses/RVs hooked up to the same battery which is why we try to have night time allowances. Technically I could run more, but if all of us did that without being aware of the others we would drain the battery which is not good for it. It happens every so often, usually at the very start of the summer.

        Interestingly, I do have a propane powered refrigerator which I didn't even know existed until I moved into this place.

    The challenge with electricity sources like wind and solar are that neither are reliably available, even from day to day. Snow storm or a bunch of heavily cloudy days? Insufficient solar for several days. Electricity usage is also heavily seasonal in some regions based on the needs of heating and cooling during weather. So unless you're willing to risk that to live off-grid (most people are not), you still need the same amount of electrical generation and transmission infrastructure as if you had no solar at all. The only resource that solar saves is the fuel needed to generate power during peak demands. The power plants and infrastructure still need to be built and sized at full consumer capability. The only way to avoid this would be to have enough power storage for the worst-case scenarios, like multiple days of freezing-cold temperatures with little to no usable sunlight.
