Consumers May Find Smart Appliances a Dumb Idea 347

theodp writes "As GE readies appliances that communicate with smart meters in the hope of taking advantage of cheaper electricity rates, CNet asks a big question: Are consumers ready for the smart grid? Right now, most utilities only offer a flat rate, not time-of-use pricing, so the example of a drier that reacts to a 'price signal' about peak rates by keeping one's clothes wet until a more affordable time is pretty much a fantasy. And longer-term, a big question is whether consumers will want to deal with the hassle of optimizing household appliance energy usage themselves, or be willing to relinquish monitoring and control to utility companies — with a concomitant loss of privacy. After all, losing one's copy of 1984 is one thing — losing one's lights and refrigerator is another thing altogether."

    As a single guy (rare for Slashdot, I know..) I don't use much energy at home during the day because surprise surprise I'm out at work. On the other hand, I'm sure there are many people who have families where one adult is home part of the day and probably takes care of cleaning, laundry, etc. during that time, probably watches TV and/or uses the computer, has kids to entertain, needs air conditioning in the summer, heating in the winter, etc. It doesn't seem like smart electronics are going to substantially change these behaviors. Great, the dryer wants to wait until off-peak to dry my clothes, but I have 3 loads of laundry to get done..

    What may change things is something that we've discussed here several times: Electric cars that have the ability to return electricity to the grid during times of high demand. Hopefully this or other means of localized power storage will reduce the need for "peak" pricing in future. Hopefully devices will also consume less power in future. For example, if you're spending time online with your notebook you aren't drawing anywhere near the 100-200w you would if you were using a desktop system (my Eee 1000HE netbook draws 9-12 watts).

    I would rather see us find ways to better match power availability to demand instead of a short-lived period of doing the inverse. Electric cars are a great way to do so because it's a natural leverage of developments in our lives that are already taking place with widespread support.

      I agree with you... The biggest energy users in a typical home are items that pretty much need to stay on consistently day and night, anyway. My water heater is like that. No point having it if I only get hot water on demand *some* of the times I want it. The refrigerator will spoil all the food if it shuts down to save energy during "peak hours" of the day. And I already have a programmable thermostat for the A/C and furnace, but I've never seen any real cost savings by setting it up to run less often

        Tankless water heaters only heat the water when you need it.

        Your refrigerator could apply a colder temperature before peak usage period, to reduce the amount of cooling that should be needed during the peak time, or apply other measures "in anticipation" of approaching peak usage period..

        "Electric-only vehicles will be a huge drain on the power grid. "

        This meme always pops up, and is untrue as the existing infrastructure is perfectly capable of handling millions of electric vehicles.

        "Since utilities have built enough power plants to provide electricity when people are operating their air conditioners at full blast, they have excess generating capacity during off-peak hours. As a result, according to an upcoming report from the Pacific Northwestern National Laboratory (PNNL), a Department of Energy lab, there is enough excess generating capacity during the night and morning to allow more than 80 percent of today's vehicles to make the average daily commute solely using this electricity. If plug-in-hybrid or all-electric-car owners charge their vehicles at these times, the power needed for about 180 million cars could be provided simply by running these plants at full capacity."

      I don't welcome greater government oversight in my private life but I do welcome a more refined two way grid because it may facilitate a "nano" economics and the necessary infrastructure. I just made up the term nano economics and may I rot in hell if it catches on as yet another catch phrase but the idea of individuals and small groups having the means necessary to incorporate into larger entities and supply small quantities of resources for exchange over a grid or in a larger project has many attractive features. Recently /. ran a story on music indies being under fire from large corporations trying to corner markets. A sort of nano economics could have positive benefits from small business startups to undermining unconscionable copyright laws. One of the things missing is a government interface such as might develop from managing power grids at the micro level and burgeoning into a nests set of systems that would allow for a broader array of nano economic possibilities. Some developing countries have experimented with micro banking wherein community members pool small sums of monies to help startups get going. I think a nano economic revolution is available via the current technology but will require the necessary government infrastructure and a shift in thinking and practise on the part of the public. Perhaps mature, industrial countries with the requisite resources and an educated working class could bootstrap such a micro revolution.

      I see your point, but I am not sure if you see the point of the article. One issue, as I understand it, preventing the use of renewable energy is their lack of ability to supply energy at peak times. Right now, apparently, we have infracture that is mostly not used, except at certain peak times. This is a social problem, not an engineering problem. Takes roads for example. We can build roads so that people can get to work at peak times, but that does not provide a long term solution. The long term solution is social.

      Localized energy storage is not going to provide the 100% guaranteed power we require in the US. There is simply no tolerance for unreliability. Localized power returned to the grid is useful if the grid can store the power, so that the power is not wasted, otherwise it is simply an incentive for people to generate power, just like the peak power rates.

      Such a policy of peak pricing may be temporary, but it may last long enough to change behavior. There are many tasks that can be done overnight if the automation is put in place. This will require investment, and one way to spur the investment is to make energy expensive.

      Also, such pricing does have an effect on conservative users. When I was younger, I went to great length to keep my power usage below a threshold, because below that threshold I was changed very little. As soon I crossed the threshold I was charged a lot more. It encouraged me to watch my usage.

      The reason people dislike this kind of plan is because they don't want to give anything up. They want to have low fuel consumption, but they want it in a military transport. They want low electric bills buy they want a big screen TV. They want to save money, but can't because they spend it on bottled water and energy drinks. The reality is that we need better management of power. It has to visible, not hidden so that people think there are no negative consequences. If that means lowering the energy cost for those that even out their power usage and increasing costs for those who don't, well that is one tool we have in the free market.

Customers with displays in their homes have said they've found them useful, even elderly people not quite so up on techie stuff. Many times it's just a matter of knowing to wait an extra hour before turning something on. The newer meters will also let the power companies know give different rates at different times, no more just asking people to wait until off peak, they can give cheaper electricity then.

    I was very close to someone who, in all intents and purposes, had a "smart" house. Practically every key component of the house, including lighting, air conditioning, and heating, was controlled by a computer running some Microsoft product. (I forgot the name of it, but it runs great!) Considering that most of the family was blind, this network made their lives a lot easier.

    However, I can see the benefits of "smart" houses being useful for everyone. Massive living room speakerphone connected to Skype and POTS could come in handy. Morever, appliances now a days are already "smart" to some capacity when compared with their predecessors. We see this on timers in air conditioners and refridgerators as well as cooking thermometers on ovens and stove-tops, for instance.

      The fridge consumes a lot of power in a home, but in a rather "distributed" way, does not really peak too much. Moreover, it would be possible to have the fridge relax a bit the thermostat requirement for a couple of hours if peak conditions are detected. It will not spoil your food to have it frozen at -17C vs. -18C for a few hours!

          If you don't remember, 2006 was a particularly hot summer, and New York had a series of nasty blackouts, particularly in Queens. At one point, 10 of the 22 feeder cables to Queens literally burned up due to the excessive heat and demand, leaving the residents without power for weeks. Although there indeed should have been safeguards in place to prevent this, I think that it's preferable to lose AC for a few hours than it is to suffer through a prolonged blackout.

    If you publish a schedule of prices, and I can save money by modifying my behavior, I'll do it. With the appliances I have.

    Example: Puget Sound Energy experimented with giving us peak rates, so we began doing laundry later in the evening. We used the delay timer on our dishwasher to make it start itself at about 4am. At no point did we wish we had Internet 3.0 appliances.

    By the way, PSE found that most people disliked the peak rates program. The discounts for modifying your behavior were not generous enough to make it worth the hassle for most people. I live in the suburbs near Seattle, so we have relatively cheap (mostly hydro) power anyway.

    So, for success, make up a simple table of rates vs. times; make sure the discounts for off-peak power are sufficient to adequately reward the people who modify their behavior; done. You can do this now, and no one needs new appliances.

    P.S. I did actually RTFA, and there is a bit more to their ideas than just Internet 3.0 appliances.

    That the "Smart Appliance/grid" proposals seem to be skipping the simple, obvious, and substantially less problematic option in favor of a complex mess of remote control crap.

    Fact is, the farther from base load you go, the more the marginal unit of electricity costs. No getting around that, barring amazing advances in generation or storage technology. Because of that, there are clear efficiencies to be had if load that can be moved off-peak is moved off peak. Unfortunately, the "smart grid/appliance" setups that involve utilities remote controlling your stuff are invasive, complex, and downright paternalistic.

    Far better would be a simple price signalling mechanism. The electricity company's meter would report, every period(could be simple "off peak"/"on peak" could be each hour, could be each minute, could be each second, doesn't matter in principle) the cost of a unit of electricity consumed during that period and the value of a unit of electricity sent back to the grid during that period. The reporting would be via a standardized protocol on a standardized header on the unit and/or over the powerline and/or a standard wireless mechanism(again, details aren't wildly important).

    That reporting would be all. If I wished to adjust my usage to save money, I could purchase appliances capable of interpreting the standard electricity price information(either built in to the appliance, or in the form of a smart breaker box, that could turn on and off power to specific outlets). I could then program the device or devices to respond as I wished to price signals("AC: NEVER go above 80c, go to 68 if price is less than 10cents, go to 70 if price is between 10 and 15 cents" "Dishwasher: do not run if price is greater than 10 cents, unless override button is pressed").

    This scheme would have three major virtues: First, it would avoid the invasiveness of having somebody else control your home systems. Second, it would allow each individual to set his own priorities on the value of various uses of electricity, rather than a one-size-fits-all approach. Third, it would allow unconstrained innovation/optimization by device manufacturers in what options to provide and how granular to be.

    For instance, a computer could be set to manipulate its own ACPI settings according to the current price level, wifi devices could trade off between throughput, range, and power in response, AC could adjust target temperature, etc. Devices that store or generate electricity on site would know their own costs of operation, and only operate when economically viable. If a utility, for whatever reason, was facing capacity problems, they could simply raise the price of a unit sent back to the grid, to encourage local generators to start up.

    Obviously, serious configuration of the details in each device would be substantially beyond the interests(and quite possibly the capacity) of a lot of people. For them, manufacturers could simply provide a suitably small set of sane default options(probably the same ones that a one-size-fits-all policy would apply across the board). For complex programmable devices like computers and game consoles, interested organizations could even distribute suggested settings packages over the internet.

    I love the entirely ignorant and self-absorbed "I'm alright Jack" and "Keep the Gubmint Outta My Fridge" and "I want the right to burn dioxins on my own lawn" comments.

    Goodness.

    For a start there's at least two sorts of appliance smartness that are useful.

    1) For example, load-shifting use until there is low demand on the gird. Sometimes that electricity can be practically free (or even negative price) and reduces infrastructure costs (hardware built to cope with a smaller peak) and reduces use of often dirty and expensive 'peaking' plant. You don't have to subscribe to Climate Change to see this as a good idea. And yes, for the average family home the main candidates are the dishwasher and the washing machine. Just avoiding running your dishwasher right after dinner (until you go to bed or optimally ~3am) in the UK right now saves circa 100g CO2 emissions each time for no inconvenience at all usually:

    http://www.earth.org.uk/note-on-UK-grid-CO2-intensity-variations.html [earth.org.uk]

    http://www.earth.org.uk/_gridCarbonIntensityGB.html [earth.org.uk]

    And indeed right now since the highs and the lows are at fairly fixed times then a simple timer will do a good job: not much Big Brother smartness there.

    But as more intermittent power such as wind comes on line, those 'excess power available' moments will be less predictable. A really smart dishwasher lets you run it just when you want to, but if you're not in a hurry you could set it for "make sure it's done by the morning, but try to pick the time for minimum costs/emissions". I already do this in my house.

    2) Balancing the grid cycle by cycle is a separate issue. In the UK fridge/freezers alone correspond to a base load of ~2GW. If a 'smart' fridge notes that the power frequency has dropped because the grid is struggling then it can postpone restarting the compressor so as to stay within normal temperature limits but coast a little while on its store of 'cool'. It might also suspend any auto-defrost for example. That helps keep the house lights on (yours and everybody else's) without spoiling your butter or denying you any rights at all. Last year we had a major nuke trip out in the UK and 500,000 people across the UK were 'load shed' and lost supply entirely. If all the fridges had been smart they may well have stayed on line without anyone noticing.

    This is not to deny that such a mechanism can be royally f**ked up by individual governments and utilities, but going purple in the face while ignoring that the alternatives may well include more blackouts or higher prices, even ignoring climate-change issues, doesn't help.

    Note: I already do some of this at home. I still haven't voted communist (though they may have had a local candidate here for the last elections).

      A well written & informative comment - to which I thought that I would reply rather than mod up.

      The big thing to note is that we are not talking about the white meter system that we have had in the UK for decades, this gives you cheaper electricity at night for powering storage heaters and the like — although I have known people also run washing machines, etc, off them.

      The big new innovation is getting appliances to switch off for short periods, eg when the adverts come on in a popular TV programme many kettles are switched on. Also when a major generator trips out it can take time to bring something else big on-line, the smaller quick-start generators are costly. Currently this is done by bringing in more expensive generators for short periods [wapedia.mobi], also large industrial users (eg Aluminium smelters) will get cut at very short notice.

      So the idea is to switch off your freezer/washing-machine for 5-30 minutes so that other more important appliances do not need to be switched off. Thus we all gain at little inconvenience.

      However it is something that is to the benefit of everyone if we work together. Those freetards who do not cooperate get the benefits without the cost or inconvenience, but this happens elsewhere, eg: vaccination, if most of the population is vaccinated against mumps then the best strategy for an individual is to not get vaccinated and thus avoid the small risk of vaccination side effect; however if everyone does this then mumps becomes endemic again.

      Come on guys - we are civilised and know how to act in the common good!

      I think we can distinguish between two types of "smart" meters:

      - (a) meters that let information flow *into* our house from the electricity company (like "supply is currently tight, minimize your usage"). To which we can either instruct our own appliances to respond like "Ok, if it's really tight now I'll wait 20 minutes", or empower the "smart" meter to tell an appliance "Appliance XXX, switch to standby until I tell you to restart".

      - (b) meters that let information flow *out* of our house to the electri
