The ability to reroute power is already there. It's just a matter of integrating the technology together and installing it all over. That is where the problem would fall as it would cost a lot of $$$$$.

    I would fear that a "new electricity net" would be less secure than the current control systems because the control nodes would inevitably be connected to the public internet with packets tunneled via a VPN to the central office. I don't see power companies laying their own independent fibers for connectivity. And even if they use their own BPL, there is a good chance the control nodes, sensor nodes, and ccentral office will be connected to what is a public-exposed BPL net. The cost efficiency of routing packets over the public net are just too tempting. Despite best efforts, I'm sure someone will figure a way to hack into the sensor nodes, control nodes, or the central office if it is connected to a public internet.

    The current system is more secure (if unreliable and uncontrollable) because compromising it requires physical access.

      The technology they are reffering to in reality is PHM (Prognostics Health Management) or sometimes called Prognostics and Diagnostics.

      This is a form of fault detection that detects something much earlier where you can either go perform maintenance on the problem before it breaks or reroute power from the problem area and go fix it. Either way it keeps the power up and is transparent to the user

      Fault detection has come a lot way since the days of the 1950s. Hell it has come a log way from 10 years ago

      Say you can detect a problem in the power grid hours or even days before it causes something to break in the grid. You can have a repair guy go out and fix it or if you can't get someone to fix it in time you can reroute power around the problem until you can get it fixed.

      From a technical side it can be done and it is a networked approach but nothing says they will use the internet or it will have the same kind of problems from users accessing it.

      100% correct.

      Absolutely correct again. The problem is that after deregulation power companies send their power to whatever area will pay the most $$$. This is not always the place that is in the most need of power. Thus many lines have a lot more power going through them than before deregulation. In addition electricity is being carried much farther than before. This is not how the grid was designed, and is a partial contributor to the august blackout.


      I agree with the article. We need to upgrade the US power system. An alternative would be to do away with deregulation and go back to using the grid as it was designed. (This would require a political change and probably won't happen.)

      Moreover, grids are deliberately designed (1950s or not) to channel energy where it's needed. This prevents overloading or underpowering.
      I'm sorry, but the second sentence is just false. The assumption of the grid is that there is always sufficient generating capacity to meet the instantaneous demand. If demand exceeds supply for any reason, part or all of the system can be under-powered. This is what happened on 8/14/2003: lines carrying power to portions of Ohio went down, causing local plants to overload and trip off-line and beginning the cascade of failures.
      When ever there is a power outage, a grid must be brought back up slowly.
      This is why it is so important to prevent large outages. Small-scale load shedding is a vast improvement over any big failure. Systems which can react to an under-power situation fast enough to dump a few neighborhoods or plants before the generators or lines have to trip off will prevent outages from growing larger.

      Cutting off customers is a poor substitute for demand-side management [doe.gov]. When there's a run on, say, toilet paper or gasoline, prices rise or suppliers run out. Latecomers delay their consumption and everyone has an incentive to decide how important it is to have the goods right now vs. later; there is no way to bring down the toilet-paper supply system. We have no such buffer like this for electricity; because of the false assumption that electricity will always be available when you flip the switch, too many people flipping the switch can cause everyone's power to go down. We need to address this sooner rather than later.

      Although I hate calling a bug a "feature", the fact is that blackouts are often a testament to fault-detection which could otherwise overload a grid and cause more substantial problems that would take longer to resolve.
      Fault detection is one thing. A faulty response to detection of a fault is another; if the system reacts to a shortage of generation capacity by cutting off generation rather than consumption, the protective systems act to decrease reliability. We may need measures such as mandatory utility control over air-conditioners (the major loads during summer demand peaks) in order to get a handle on this problem.

Just as the internet has enabled information workers to telecommute, distributed power production can do the same for power plants (not that power plants commuted in the same sense as office workers).

    However, decentralised systems can also faile - indeed, given perfect information at the centre (a big given, which often fails) a central overview can outperform a local intelligence. With a distributed system, you would probably get smaller but more frequent outages as local subsystems panic, with a larger total number of houshold outage minutes. This migh, of course, be less damaging if humans don't panic because it is only a few tens of blocks down.

    The big potential gain, mentioned lower down in the article, is the potential structural changes to allow small scale generators to generate and distribute power locally. Lots of places have backup power generators, which cut in only when the mains fails. If the economics are right, it would be weorth while their running these continuosly, selling surplus power to the grid, and using the grid as a backup for their own power generation rather than the other way round. This saves the capital investment required for power stations, since it is using capital already invested instead of new capital - which may therefore overcome the diseconomies of small scale. It also saves the losses of long-distance power distribution. However, where you really win is that each area hasa a large proportion of its own power generated locally, so it doesn't care if the grid goes away. Suddently, it soean't matter what happens elswehere. there is also a cewrtain natural balance, as electricity is used in workplaces dirung the day, and when the workers go home the power is available for their domestic evening peak.

    The real pie-in-the-sky payoff is when we all get hydrogen-powered cars, which generate electricity for no wear and tear on the fuel cell (we hope). If every car parked at home or work plugs into the grid, you have more generating capacity than you will need in the near future. (It is quoted that the power output of one year of US car sales exceeds the installed generating capacity of the entire world).

    Considering the costs involved and the time it will take to get it going, I think wireless broadband is going to beat it to the punch. Wireless Broadband should be pretty heavily installed (kind of like early cell companies, but faster) within the next few years, and with 802.16e coming (mobile 802.16) then it will have yet another advantage over Ethernet over power lines.

    I'd rather the drunk drivers have to drive a semi into a tower to take my internet out anyways :) At least then they won't do it again...hate to be the poor schmuck that has to go check on that equipment outage though.

    I think if the IT market moved slower, say stretched out about 10x, then there would have been room for ethernet over powerlines, but as it is it is I think the window of opportuniy for it has already come and will be gone before they manage to get major systems up and running. I've worked with power companies, I know how long it takes them to do anything.

    I mean if an OS upgrade requires 6+ months of wait time (not 6 month after it comes out, 6 months after they decide it might be safe to use) and several to many nuclear plants are still running Windows Nt 4, how long do you think it will take for them to decide to do something that will affect all of their lines?

    Encourage people to have power generation in their own homes. Solar panels, generators, etc, designed for home use, would not only ease strain on the grid during hot days in the summer, but would also make their owners money, and make them energy independent.

    This would also provide security in an attack, because the entire electrical grid will no longer be supplied by a few power plants that are large targets for any attacker.

    The only reason this wasn't implemented during the Cold War is because the technology wasn't there yet, but it is now. And what better way to promote the hydrogen economy that having people put fuel cells on their property to power their house when the main grid fails? People who don't want to have hydrogen in their cars probably won't mind having a tank in their back yard. A lot of people already have tanks of propane for heating and cooking where there's no natural gas service. (Yeah, yeah, I know it's not a cryogenic liquid, but it sure does explode like hydrogen.)

    This would create a distributed network of power generation, and no RIAA-like actions by Al Qaeda or Mother Nature would be able to bring much of the grid down at any one time.
    • Not goin' to be easy. Here in Denmark, when the grid went down last year, all the windmills came to a standstill. As long as you work with AC, you need someone to set the frequency and the phase. Switchin the whole damn thing to DC would make it easier, but that is one hell of an investment.
    • Security in an attack? Yeah, possibly. Fix blackouts by easing the strain? Pretty doubtful. I think more likely a bunch of power plants will close up shop and then all of a sudden you have roughly the same amount of available generation you did before, only its less reliable now because the wind could die or it could be overcast all week.

    Slightly offtopic, but I recently purchased one of those Phone-Line through the Power Lines adapters from Radio Shack.

    What you do is plug one adapter into the wall circuit in a room with a phone jack, and hook the phone line up to it. Then, in another room without the phone jack, you plug the 'receiver' into the wall, and you can plug a phone into it.

    Strangely enough, it works. I can even connect to the internet (at 28.8 or less, usually) through this circuit.

    BUT - and a big BUT at that, is I keep on getting mixed lines, I hear other people talking on the line, and the most annoying part of it is that whomever's line I am crossed with, when they make a phone call to somewhere else, MY phone number shows up on that person's caller ID. So then I get phone calls at 1am from shady people asking me "Did you call here?!?". At first it was fun listening to their phone calls, apparently someone's boyfriend got caught in a drug deal and needed to be bailed out, but after 4 or 5 of those 1am calls I decided to ditch the whole thing.

    So, I for one would not be too interested in this technology unless I see it proven first. In someone else's house. And knowing how bad it worked for the phone, I'm scared stiff to know what people could grab off my line if I use it for the internet.

  • If the internet via electricity grid becomes more widespread in the future, will the internet become unreliable? If the power goes out (as it did during the East Coast Black Out of 2003), the internet would lose a lot of connectivity in the areas of the black out. It would no longer matter if ISPs or bandwith providers had back up generators. They would go offline as soon as the power went off. What happens if there are rolling black outs such as the ones that happened in California a few years ago? Wo

    Okay, so the reliability of this information is obviously suspect given the source, but over the weekend I caught an Art Bell show on the radio, where the President of the American Relay Radio League claimed that interference from this kind of power line networking would essentially kill broadcasting in North America over a wide spectrum- if I remember correctly, something like 20Mhz-80Mhz. Art Bell's recap is here [coasttocoastam.com].

    Looking into it now a little further, some of the American Relay Radio Leauge documents and links [arrl.org] has some mentions of problems for radio astronomy and a few other low-profile endeavors.

    Anyway, I had no idea this was a possible outcome, and these claims make me think that perhaps it's better to insist that we really work on existing non-interfering technologies before we kill one of the few sections of spectrum that an individual can use on his own.

    The Economist, which I've read for many years, used to be scrupulously neutral and very accurate. Then, a few years ago, articles started to appear which sounded like they came from the Heiritage Foundation. Like this one.

    The "electricity internet" scheme comes from the people who think free markets are the answer to everything. When free markets fail, they say they weren't free enough.

    That group architected California electricity deregulation, with a power auction every half hour around the clock. Nobody was held responsible for electrical reliability,; the "market" would insure there was enough supply.

    This was an absolute disaster. We had blackouts. The biggest electric utilities in California went bankrupt. Rates went up. Even the major energy trader, Enron, went bust. And we're still paying for the mess.

    The "electricity internet" scheme is a plan to provide more transmission facilities. But not because they're needed for power engineering reasons. The extra capacity is to facilitate energy trading.

    The basic trouble with electricity deregulation is that it encourages building inefficient power plants. Traditionally, regulated electric utilities build mostly "base load" plants, intended to run 100% of the time at high efficiency, plus some less efficient "peaking" plants brought up during peak periods. In a deregulated environment, wholesale electricity prices change by several orders of magnitude throughout the day. The optimal strategy for a generation company is to target only the peak periods, using low-cost plants burning high-cost fuel. (These are usually natural-gas fired turbines.) And there's no money in having excess capacity that's only used a few times per year. A few blackouts a year are to be expected. That's the result of a free market solution.

    In Californa, energy traders figured out how to create shortages. Buying, but not using, electrical transmission and natural gas pipeline capacity was one way used to drive up prices.

    The fanatical free-market types claim the problem is that the huge variation in daily rates isn't pushed all the way down to residential customers. You'd set your thermostat in dollars per day, and when the power price went up, the air conditioning would turn off. Bigger customers would have energy storage facilities. Most people would just suffer. That's the plan.

    As part of his Dymaxion "plan" (I dunno - the more I read about this guy, the more he seems like a "hippy" before his time), Buckminster Fuller came up with all sorts of radical and workable ideas and inventions (check out the "Fog Gun" - a shower for a family of four using only 1 pint of water!) - one of which was the idea for a "world electricity grid".

    Basically, he took his Dymaxion world map projection (one of the only map projection systems to lay out all of the continents on a flat surface with little to no distortion, showing all the continents in true size/proportion/distance to each other), and layed out the major grid interconnects for world power onto it. The idea being that if the world was using one single power system (heh, a logistic problem in itself, what with differing voltages and frequencies), that fluxuations in consumption and use would be smoothed out worldwide because when half the world was at peak, the other half would not be, thus allowing everyone the benefit of everyone's resources - basically a large power sharing network.

    Of course, as one reads more about Bucky's ideas and theories, one quickly realizes that what he puts forth is a complete system for living in harmony with the Earth, its resources, and all of the people on the planet - you can't just take portions of his ideas and use them, ignoring the rest. To do so would be folly and would insure that what you were trying to do would eventually fail...
