Are Corporate Interests Holding Back US Electrical Grid Expansion? (ieee.org) 133

Long-time Slashdot reader BishopBerkeley writes: Though it does not come as much of a surprise, a new study highlighted in IEEE Spectrum delves into how corporate profit motives are preventing the upgrading and the expansion of the U.S. electrical grid. The full report can be downloaded here from the source [the nonprofit economic research group NBER].

Besides opening up the market to competition, utilities don't want to lose control over regional infrastructure, writes IEEE Spectrum. "[I]nterregional lines threaten utility companies' dominance over the nation's power supply. In the power industry, asset ownership provides control over rules that govern energy markets and transmission service and expansion. When upstart entities build power plants and transmission lines, they may be able to dilute utility companies' control over power-industry rules and prevent utilities from dictating decisions about transmission expansion."

The article begins by noting that "The United States is not building enough transmission lines to connect regional power networks. The deficit is driving up electricity prices, reducing grid reliability, and hobbling renewable-energy deployment. " Utilities can stall transmission expansion because out-of-date laws sanction these companies' sweeping control over transmission development... One of the main values of connecting regional networks is that it enablesâ"and is in fact critical forâ"incorporating renewable energy... Plus, adding interregional transmission for renewables can significantly reduce costs for consumers. Such connections allow excess wind and solar power to flow to neighboring regions when weather conditions are favorable and allow the import of energy from elsewhere when renewables are less productive.

Even without renewables, better integrated networks generally lower costs for consumers because they reduce the amount of generation capacity needed overall and decrease energy market prices. Interregional transmission also enhances reliability,particularly during extreme weather...

Addressing the transmission shortage is on the agenda in Washington, but utility companies are lobbying against reforms.

The article points out that now investors and entrepreneurs "are developing long-distance direct-current lines, which are more efficient at moving large amounts of energy over long distances, compared with AC," and also "sidestep the utility-dominated transmission-expansion planning processes."

They're already in use in China, and are also becoming Europe's preferred choice...

        I find it interesting that people are working on long distance DC systems, since it was direct currents weakness in that area that caused it to be replaced by AC even though Edison backed it.

        Back in Edison's time, Tesla's AC distribution system initially won the "current wars" for one reason: DC voltage couldn't be transformed efficiently. That meant there was a choice between minimizing I^2R transmission losses by delivering unmanageably high and dangerous voltages to end users, or accepting huge transmission losses. (DC was doomed to fail anyway, irrespective of transmission losses. Firstly, things like domestic radios, really needed multiple voltages. Secondly, DC motor speed varies with applied voltage, so accurate electric clocks would have been very complicated to say the least. The speed of AC synchronous motors is dependent only on the frequency).

        But these days, converting from AC to DC and back can be done much more efficiently than even a few decades ago. It's still complicated and a pain in the ass, but for long distances DC is more efficient. AC introduces skin effect, along with higher peak voltages and currents for a given amount of power delivered. These factors necessitate larger conductors than would be expected by a simplistic Ohm's Law calculation. Also, even at 60Hz, both radiative and reactive losses become significant for high voltages and long lines. So for really long distance transmission, the efficiency gain and smaller wires associated with DC are worth the cost and hassle.

          the last I read (years ago) was that at the long distance transmission voltages used back then, AC had less loss, but when you get to even higher voltages, which we would use in a new system, DC has less loss.

          The modern efficiency in converting DC is, afaik, just icing on the cake.

          the question remains, though, whether the efficiency gain would be enough to pay back the conversion costs.

          Stated a different way, the free market isn't good at infrastructure or actually indeed most things.

          I will argue the opposite. The free market, in fact, is actually good at many things. The difficulty is that too many people who see that the free market is good at many things go on to assert that therefore the free market is good at all things. This is unfortunately not true.

          (and also, as you point out later, in the real world there are really very few markets that are totally free and unregulated).

          Free markets don't care about societal good, unless that societal good happens to align with prices and supply.

          That is a key point, and your "unless" clause is also important.

          It is argued that providing goods and services to people who need them at competitive low cost is a societal good, and that a frictionless free market gives these people the ability to choose the goods and services they want from a panoply of providers, allowing them to make their own decision of price versus quality.

          But it is also worth noting that "buy stuff cheap" is not the only societal good.

          In this case of electricity transmission, the market is not a free market, as government mandated and protected monopolies are widespread. So, this market doesn't even try to optimize prices and supply. Rather, the current market focuses only on optimizing profit.

          More complicated than that. Some businesses are natural monopolies, and for these the monopoly nature isn't "government mandated," it is government regulated to avoid the bad effects of monopoly (which are many, and well known.)

          This does, as mentioned in other threads, give the possibility of regulatory capture, where the regulated industry uses the regulation to keep competitors out. But in an industry that tends toward natural monopoly, this can be the lesser evil.

          Phrased another way: it's complicated.

      • Virtually all US power supply and transmission is controlled by government enforced regional monopolies. It bears very little resemblance to a free market.
    • No, it really is corporate interests. And it isn't a market failure as much as it is companies lobbying state governments to do things which wreck the free markets. For example, some US states have laws which make it difficult to build transmission lines into that state if one doesn't have generation in that state. That has made it very difficult to make new transmission lines for wind power from the Midwest to states in the Southeast.

      Single line infrastructure can't be private owned - that's literally a monopoly even if heavily regulated. It's billed as 'cheaper' to outsource, but we're here now and they aren't expanding it because they can't make *enough* profits. Public infrastructure doesn't need to make a profit - it needs to serve the public at reasonable cost. Also see why every municipal cable system is wildly more popular than private corps.

WAY too many people are bitching about rates paid to them for selling back extra solar to the power company. Stop using the grid as storage and backup.

    Looking at new appliances? Inductions stoves, hybrid heat-pump water heaters, mini-split heat pumps instead of A/C and heaters, condensing dryers -- lots of stuff runs off of electricity and uses WAY less power than the old stuff. Some of it may cost more up front, but ROI on these can be just a couple of years depending on how much you use them.

    Add to that the ability to break the oil/gasoline addiction, not worry about major utilities screwing you over, grid stability, or any of that shit adds a whole lot of value that needs to be considered. Take a hard look at the government incentives and tax credits available and stop leaving yourself at the mercy of multi-national corporations who don't give two shits about you.

    This is entirely unsurprising. Regulated industries love to use regulations to prevent competition. It's a strategy as old as time: get the government to grant you a monopoly and you've got a steady, predictable revenue and profit stream. Sure, you might have trouble raising rates as much as you'd like but you don't have any pesky upstarts trying to take your business.

    This is a classic example of how we think government regulation is in the consumer's best interest but open market competition might regulate the players much more effectively.

Phone manufacturers pushing 5th gen. wi-fi, or EV manufacturers pushing the Tesla charging plug. Notice the separation of services: The company that builds phones does not own wi-fi networks.

        That's a pretty happy development of the 21st century. I think we're finding fewer and fewer

    • This is a classic example of how we think government regulation is in the consumer's best interest but open market competition might regulate the players much more effectively.

      I dunno man. This isn't like a network where you could route around providers who are not offering an honest deal. Letting Jimbob run a power plant of his own choosing seems like it would be more regulatory trouble than it would be worth considering the myriad of ways it could all go wrong.

  • Yeah, I know they have problems, but they suck less than investor owned utilities

  • Any question that is essentially "are corporations screwing over something", the answer is always yer.

    The reason you may see AC described as better is that low current is more efficient, which means high voltage, and AC lets you step voltages up and down with only Victorian technology.

    If you have the tech to step DC up and down, it's got a key advantage on the high voltage leg. If peak voltage is average voltage, as it is for DC, you have less problem with corona discharge.

    • You have massively simplified power transmission. There are trade-offs everywhere for the use of both AC and DC. Efficiency for DC is king in HV transmission. But you trade off reliability (rectifiers are far less reliable than transformers) and safety (it's much easier to interrupt a high AC current than a high DC current (providing you don't have a huge reactive load). In terms of power engineering corona discharge is a far easier problem to deal with.

      That said with today's tech DC transmission is going t

        Just for fun . . . how much current would have to be suddenly interrupted for a line, say, 100 feet from the freeway, to throw a magnetic field that would give the passing cars a noticeable tug?

  • At one time, I got to eat lunch with some techs from our local electric company. They told is tales of how the company won't replace bad equipment until it cannot be patched anymore. Our city's sewer plants are supposed to be dual fed for power. A windstorm took down one for almost a month regardless of the promises.
  • The utilities are monopolists guaranteed a return on their capital investment. This is the deal that was made to get private investment in the electric grid 100+ years ago. The utilities would love to invest and spend more, take risks and even use proven technology to reduce their costs and save the environment. We have had easy ways to reduce costs and pollution for 40 years. However the public utility regulators have to approve any new capital investment. These organizations are the dumbest organizat

    If we started building new infrastructure, someone might find a job and start a family. And we can't have that now, can we?

    Recalling the last major blackout... the fault induced by a tree in a poorly maintained power line right of way propagated from Ohio (I recall) across the Northeast, taking out the lights in Ontario and elsewhere. Only the DC-DC firewall between Ontario and the Peoples Republic of Quebec blocked it from propagating further. One massive interconnected grid is great for shuffling electrons from one place to another. But when things go wrong ensures that great swaths of the country get to suffer in sympathy. The old isolated local grids were great for restricting the damage. But not anymore. And the isolation needed to contain any damage is not cheap. So if we are in a big rush to electrify the country there will be a few corners cut. Save the planet... after all. Until some hostile hacker takes the grid down.. or the Sun barfs out another Carrington event. Sigh...

  • That's the way things work these days: what matters is to make as much of a profit as possible in the next quarter. Anything beyond that is somebody else's problem.
  • That way it can be a true house of cards. Just see the recent AT&T news, now imagine it was the power grid and included T-Mobile and Verizon....
  • Those damn corporations. They expect to make a profit. Who the hell do they think they are?

      Ah, yes. Oh, our city is being besieged, and you want the food in my warehouse? No problem, you'll just pay 100 times what you would when there's no war. Can't afford that? Sorry you can starve to death.

      Insulin was discovered a century ago, and the discoverers sold the patent for $1 (that's one dollar, US), so that it would be cheap. Lilly was sued - one person "aged off his insurance, and was looking at a $1300/month insulin bill".
