They're Frustrated with Power Utilities - So They're Leaving the Grid Altogether (msn.com) 239

Power blackouts and rising electricity costs have inspired "a small but growing number of Californians" to leave the power grid altogether for their own home-generated energy, reports the New York Times.

And thanks to "a stunning drop" in the cost of solar panels and batteries, "Some homeowners who have built new, off-grid homes say they have even saved money because their systems were cheaper than securing a new utility connection...." Nobody is quite sure how many off-grid homes there are but local officials and real estate agents said there were dozens here in Nevada County, a picturesque part of the Sierra Nevada range between Sacramento and Lake Tahoe. Some energy experts say that millions of people could eventually go off the grid as costs drop....

People going off the grid argue that utilities are not moving fast enough to address climate change and are causing other problems. In Northern California, Pacific Gas & Electric's safety record has alienated many residents. The company's equipment caused the 2018 Camp Fire, which killed dozens and destroyed the town of Paradise, about 70 miles north of Nevada City. The utility's effort to prevent fires by cutting off power to homes and businesses has also angered people. One of those residents is Alan Savage, a real estate agent in Grass Valley, who bought an off-grid home six years ago and has sold hundreds of such properties. He said he never loses power, unlike PG&E customers. "I don't think I'll ever go back to being on the grid," Mr. Savage said.

For people like him, it is not enough to take the approach favored by most homeowners with solar panels and batteries. Those homeowners use their systems to supplement the electricity they get from the grid, provide emergency backup power and sell excess energy to the grid.

The appeal of off-grid homes has grown in part because utilities have become less reliable. As natural disasters linked to climate change have increased, there have been more extended blackouts in California, Texas, Louisiana and other states.... Installing off-grid solar and battery systems is expensive, but once the systems are up and running, they typically require modest maintenance and homeowners no longer have an electric bill. RMI, a research organization formerly known as the Rocky Mountain Institute, has projected that by 2031 most California homeowners will save money by going off the grid as solar and battery costs fall and utility rates increase. That phenomenon will increasingly play out in less sunny regions like the Northeast over the following decades, the group forecasts....

Some energy experts worry that people who are going off the grid could unwittingly hurt efforts to reduce greenhouse gas emissions. That is because the excess electricity that rooftop solar panels produce will no longer reach the grid, where it can replace power from coal or natural gas plants. "We don't need everybody to cut the cord and go it alone," said Mark Dyson, senior principal with the carbon-free electricity unit of RMI.... Scott Aaronson, a senior vice president for security and preparedness at the Edison Electric Institute, a utility industry trade group, said that while off-grid living might appeal to some, it was "like having a computer not connected to the internet.... You're getting some value but you're not part of a greater whole," he said. "When something goes wrong, that's wholly on you...."

Off-grid systems are particularly attractive to people building new homes. That's because installing a 125- to 300-foot overhead power line to a new home costs about $20,000, according to the California Public Utilities Commission. In places where lines have to be buried, installation runs about $78,000 for 100 feet.

The article ends by pointing out that off-the-grid residents will soon also have a handy alternative to the giant electric batteries that store the excess energy from their solar panels: electric cars like the Ford F-150 Lightning and the Hyundai Ioniq 5.

        Yeah, it's a really small change, and they're reporting on a restricted market. But it actually is a real change, and it may be a lot larger than they're reporting, because their reported (in the summary) method of collecting data is, frankly, anecdotal.

        That said, if people are, indeed, saving money then one can expect the trend to grow. Actually, one can expect the trend to grow anyway, even at "not quite breaking even", because one of the payoffs is not having to deal with paying the bill every month or

      Most utilities would be happy not to have them connected so they don't have to worry about them messing with grid stability if enough come on line; as well as pay more for their power than other generation sources as is sometimes mandated by the rate rules. Integrating them into the grid on a large scale basis would mean having a control system that makes homes 100% interruptible, something that would probably be politically diffiult and a PR problem teh first time a home gets disconnected and something bad

  • It's not uncommon to see rural houses with giant propane tanks either above or below ground, since they can't get natural gas service. If you have solar, you can get a battery big enough to run your house for a while that would be smaller than those tanks and can just as easily be buried as long as they're thermally suited. Heck you could have both and have a propane generator on hand just in case.

      If you use solar for heating odds are you're gonna blow through that battery bank pretty fast. Heat pumps are quite efficient but a propane tank holds a whole lot of energy.

      • by HiThere ( 15173 )

        It's legitimate to point out that you'll need a lot more battery than you might expect. and that the battery needs to be sized to the appropriate expected usage (with a bit of spare). And that batteries are expensive. This means the costs are more than a simple direct size-for-size replacement. But if you've got sufficient space, it could quite well be a reasonable approach. My grandfather used to have a propane tank in the yard (perhaps 50 feet from other buildings). It was perhaps twice the volume of

        • Propane - 25.3MJ/L
          Lithion Ion Battery ~ 2MJ/L depending on the chemistry used.

          Your battery is going to need to be at least 10x as big as the propane tank to have the same capacity.
          Maybe a lot more, because if the propane tank is running empty you just order some more, whereas with the battery, you need to wait for the next sunny day.

  • Even using every incentive available to me, and pricing the absolute cheapest solar panels I can find, I can't make the math work on this. Even if I do all of the work myself, and even if I calculate in some pretty steep power cost increases - above the 10 year trend for increases - the cheapest system I can design still costs more than 30 years worth of power bills.

    I see panel farms popping up all around me, but very few on houses. What I see going up are large-ish commercial operations. And I know why

    • If you are building a house and need to get it connected, then the costs of a grid connection can make the cost of a stand-alone, battery and solar system palatable.

      • I suspect this is only true if your new house requires several kilometers of new power line need to get strung to make your new home's electrical connection.

        • Maybe the current transformation capacity is fully loaded and they can't sell more power in the same "electric distribution" area (happened to a small company I worked for once, they proposed pulling a 12+km line from a less loaded transformer).
          Maybe aerial lines are forbidden, so you must tunnel under a road (and around some water/sewage pipes).

    • LCOE for solar is $0.07; add battery and you have an extra $0.07 for the after-hours power. The more you can do to push your loads to solar hours the less your blended energy cost.

      The challenge for being completely off-grid above latitude 30 or so is the gap between summer and winter production. You end up increasing your cost by 30-50% quickly.

    • Does the payback really matter? The main thing is that the panels pay themselves off within their operating life, and during that time period you have essentially prepaid your electricity and no longer care what happens to natural gas prices, the uselessness or otherwise of the grid operator, end of civil society etc. Over a 30 year period that is a lot of peace of mind.

      I personally find it weird how, when house prices go up by $100's of thousands during the middle of a pandemic, everyone just shrugs, but w

      • I don't see what the fuss is about payback time either, as long as you can afford it then go for it. If you factored in payback time you'd never install double/triple glazing or insulate your house.

          There's a satisfying feeling that comes with being independent of the grid. Some might even call it smug.

          But when your neighbours are throwing out the contents of their fridges and freezers due to an extended outage, and you sit on your verandah enjoying a cold beer, "smug" is the correct term.

    • and even if I calculate in some pretty steep power cost increases - above the 10 year trend for increases

      My power cost increased by a factor of 3 above the 10 year trend recently, but I can't speak for California.

      I think the thing you're missing is the "new" factor here. Initial provisioning of a grid connection can be insanely expensive. I know of one person where just the provisioning was more expensive than an entire off grid setup, to say nothing of the ongoing connection fee.

      • In the UK, electricity prices are currently increasing by more than 50% every six months. They are going up 54% from 1st April, and the next review after that will take place on 1st October.

    • We installed solar panels and a Tesla Powerwall 2. For most of the year we operate nearly 100% self-powered, sending a LOT of power back to the grid. It is only the summer months when we have to rely upon air conditioning extensively that we use power from the grid. Even with that, our investment for the panels, battery, and infrastructure will be completely "paid off" in about 6 years. We're in the SoCal desert where summer temps are over 125F regularly.
    • Sorry, but you are wrong about economic viability. I know because your own post proved it. You said "the cheapest system I can design still costs more than 30 years worth of power bills." These words proved that going solar was cheaper than power bills, because otherwise you would have said "Going solar cost me more than the power bill." If it didn't save you any money at all you would have mentioned it.

      Your problem is you are pissed that the savings was too small, not that the savings did not exist.

  • ... does running overhead cable cost $66 a foot and burying it $780 a foot? Yeah, ok they might need to plant some poles or bury some conduit, but we're still talking residential conductors here. The cable is under $10 a foot, as is 3" schedule 40 PVC conduit (which you might not even need). Over $700 a foot to dig a 24" deep trench, I'm in the wrong business.

    Also, according to the NEC the power company is on the hook for overhead service entrance cabling, not the customer. Buried cable costs are the cust

    • Depends on how deep the soil is. Not far away the local mountains only have about a foot of soil before hitting solid rock. That can cause a little extra expense.
    • ... does running overhead cable cost $66 a foot and burying it $780 a foot?

      Ever done any trenching in the mountains, where the soil is full of rocks varying from pebble to boulder? It's more rock than dirt in some places.

      You know what the most expensive part of laying anything? The hole you lay it in. Mainly in the cost of getting the right of way through the land.

      When you string wires in the air in most places there are decades old laws that let power companies automatically have right away through places. These laws do not exist for burying lines. When they want to bury lines almost every foot of space has to be negotiated with someone for right of way.

    What will they do if their system breaks down?
    Do they have the tools, time and money to fix things urgently?
    Are the owners skilled enough to maintain their systems, and have they calculated that time and training in the costs?

    They may have the skill and the tools and the time to maintain and fix it properly, but it must be included in the cost. It is far more than just the bill for the solar panels.
    • by dwywit ( 1109409 )

      Solar panels are essentially large-scale semiconductors. There's not much to go wrong - no moving parts. They're also designed and built to sit in the hot sun for 20 years and still keep producing electrical energy. A well-designed system won't go down because 1 or 2 panels fail from hail damage. It's not all-or-nothing.

      Maintenance consists of semi-regular inspections, and perhaps a wash.

      Batteries come with controllers/battery management systems which look after the charge/discharge cycles, and prevent over

      • Question: when you say thirsty, just how much water are we talking here? I knew someone who was buying 60-100 gallons of distilled water a month for their home solar, and I always had a suspicion there was something wrong with their setup to be using that much water.
        • High water use in FLA batteries is caused by high C rates and/or overvoltage. They will just need more water if you're charging them near their maximums, period, but they will also go through more water if your charge voltage is excessive. These days it has become fashionable to apply much higher than recommended charge voltage to deeply discharged FLA batteries, like over 15 volts. Supposedly the studies have shown that most batteries can take the abuse without harm, but that doesn't mean they won't need m

I accept that breakdowns are unusual and unexpected, but nothing's perfect. I somehow doubt that insurance payments would cover a quick emergency repair, but without that, e.g., medical devices would be down.

        The best backup I've been able to think of quickly is to own (and keep charged) two electric cars. Switch off which one you're driving. If one of those breaks down, th

      • by HiThere ( 15173 )

        For a house to have really proper insulation, it needs to have been designed with that in mind. Add on insulation is always either extremely bulky or rather poor. Possibly the best way to add on good insulation for many houses is to add a facade to all the walls (and roof).

    • Depends on how you live. Some people use a lot more power than others. Yes, insulation matters, but if you have a family of four that install a ton of vampire e-products (things that draw power even when not in use), your 3kwh per day is way too low.

      That seems rather fanciful for the vast, vast majority of people. A refrigerator alone eats up most of that energy budget (at least 1.5 kWh per day).

      I try to not run my AC or heat at all for a couple months each in the spring and fall (so ignoring the insutlation factor). When I do, my house's electrical usage tends to bottom out around 10-11kWh or so per day.
