The Grid

I've got to tape a segment for Fresh Air about my story on the Grid in National Geographic....I hope they don't try to stump me with questions about how electricity works. Would result in much verbal arm-waving, if you can imagine such a thing. I think it airs Thursday, fyi.

Here's my story.

I remember when the grid ("Da Grid") fell on itself a number of years ago. During this hellish weather pattern I'm trying to fax an amount of good karma in numbers entirely too huge to fathom to keep Da Grid upright and working.

Along the Columbia, whose banks are draped with wires, they have to stop the windmills sometimes when the dams are running full bore, not enough wires I guess.

Grid-related question. I just heard an NPR discussion on electric cars. The panel had about 2/3 proponents of massive switchover to electric cars by, say, 2030. About 1/3 of the panelists were highly skeptical.... they quoted articles from back in about 1910 trumpeting electric cars as the future. The skeptics scoffed that the electric car has been tried off and on for a century and has failed every time.

Here is my question: could I go to a plug-in electric car that is fueled by a stand-alone solar setup. Lots of hot water heaters are stand-alone solar. What (besides cost, of course) would prevent me from seting up a solar charging station that would charge, say, 4 batteries, allowing me about 250-300 miles of go?

That type of setup would avoid the argument made by the skeptics that switching to all-electric is pretty much just switching from a gasoline engine to a coal engine.

Surprisingly, nearly all of Central America seems to be on a single grid. It's not an easy place, physically or politically, to do that.

I'm not sure whether southern Florida's shape is a good or bad thing. It's worrisome when a proposal to enlarge a nuclear plant south of Miami runs into questions about rising sea level, already a problem.

Here is a response from Plug In America:

Q: Can I charge a plug-in car with solar or wind power?
A: Yes. The cleaner the power the cleaner the car. Using solar PV or wind power at your home or business makes even more sense with a plug-in car. The investment pays off faster, and the car becomes truly zero-emission. EVs typically can travel 3-4 miles (or more) per kWh. If you drive 12,000 miles per year, you will need 3,000-4,000 kWh. Depending on where you live, you will need a 1.5kW-3kW PV system to generate that much power using about 150-300 sq. ft. of space on your roof. In fact, many EV drivers recharge their cars from rooftop solar panels today, generating virtually no pollution for their local driving.

Back to me: this seems doable, depending on how much sun my roof gets. My guess is in NH the winter will be hard to keep up with lots of driving, as the days are short and the temperatures cold.

I gotta think you have to really want to eliminate CO2 to pay for a solar charging setup AND pay the premium for the car AND pay for the routine replacement of aged batteries. Who knows?

The one nit that I would pick with this article relates to solar power. Distributed solar generation correlates almost perfectly with periods of peak use. Peak demand inevitably occurs during hot, sunny periods in the summer from 1pm to 6pm. Amazingly, that is also the same period of time during which solar power is capable of generating the most power. Solar power is often derided as uneconomical when compared to $0.08/kWh power, but in fact, the peak power that it offsets is much, much more expensive--probably like $0.50/kWh or more.

The somewhat ironic thing about Xcel Energy, who are running the smart meter experiment in Boulder and provide (backup) power to NREL (as well as Denver and Minneapolis) is that they have all sorts of tariff rules in place to discourage solar generation, including not allowing retail customers to "sell" electricity (net meter) back to the grid. While their undertaking in Boulder is interesting, it's pure PR that doesn't stand much chance of being implemented in the rest of CO or MN.

I really enjoyed this article. I thought it was technically precise and found just the right tone.

I especially liked the explanation of how frequency works as a feedback mechanism. I think a lot of people don't realize that electricity takes the notion of "just in time inventory" literally. And as I have said before, if you wanna get rich, invent better batteries.

Although robustness is, of course, the key challenge for the aging grid, another topic of concern is something called power quality.

This has to do with how precisely the voltage and current align in alternating current, as well as how closely everything approaches an ideal sinusoid. Poor power quality leads to inefficiencies and can muck up certain precision devices.

Concerns over power quality quality have led to an increasing reliance on "power conditioners." These are the electrical equivalent of water filters. They take relatively sloppy public alternating current and turn it into the cleaner and more precise alternating current suitable for more persnickety machinery.


And Joel, if you ever get caught in a bind with a tricky question just make reference to electromagnetic flux. That usually settles 'em down.

That power plant's cooling canals unintentionally became wildlife habitat: crocodiles love the warm water. The canal system was controversial due to fears that it would generate fog banks in winter. Other plants, all of them old, inadvertently became cold-weather shelters for manatees.

The not-in-my-backyard aspect of large power lines must be a huge barrier to improving electic grids in the US. For the same reason, I doubt that true high speed rail service can ever be provided from Boston to New York. Maybe not even from New York to Philadelphia.

Posted by: -pj- | July 6, 2010 3:15 PM | Report abuse

Awal, you are accurate on the peak demand x peak production. But it's not just for hot days.

In MN, the coldest days tend to be very clear and the solar efficiency actually improves due to the better conduction in the cold, so a sunny winter day in MN can actually produce a surprising amount of electricity (or so a Green show told me), as long as the snow is off the panels.
I think a very hot day would impair efficiency somewhat, but this is of course offset by the amount of solar energy pouring in. Unless we figure out how to use snow power, we'll probably be out of luck when blizzards hit, though.

Huge electric reservoirs or tapping geothermal energy as well may be the ticket.

Or, just owning a lot of huge, shaggy dogs for those cold nights.

Another problem with power lines, transformers, inversion, etc., is the massive amount of energy all of this loses (essentially, as heat), to the atmosphere. This is why they can not be buried, they would melt. Grid transmission loss is another argument for local/retail power generation.

Totally off-topic, you 'Merikans better stock up on Forever stamps cuz the Snail Mail Service wants to raise the first-class stamp rate to 46 cents.

I'm hoping to get a new sign for my local station. The letters wore off several years ago and were replaced with strips of gray electrical tape. Now the tape has gotten very frayed.

With the extra funds the rate increase will bring in, there oughta be a spare $1.79 for a new roll of tape with which to make new letters.

Sorry to hear about your injury. Recover quickly.

I work in a sub-field where loss of the power grid is considered Failure Zero when considering redundancy, meaning the system is assumed to not have electricity from the utility. From there, the question is how long the system can stay on and what else can break without anything else quitting.

seasea, maybe my mother was there earlier that day and cleaned them out of Forever stamps.

Just before the $0.41 to $0.42 increase in stamps, Mom went in to the Post Office to buy enough Forever stamps to last through all the mailing associated with my then-upcoming nuptials. When her turn in line came and the clerk asked her what she needed, Mom said "Forever stamps. I'd like about 400, please." The man looked under the counter and said he'd have to go get some more from the back. After a short delay, he comes back with a bag and says that he only has 180, if that would do. Thinking that that would at least get us through the invitations and response cards, Mom said that would be fine, and handed him her credit card, took the bag and left.

It wasn't until she was halfway home that she realized that the $1476 tab was awful high for 180 $0.41 stamps, and when she got home and looked in the bag, she realized why. She had just purchased 180 BOOKS of stamps.

We had more than enough stamps for my wedding, and she's supplied them to a few of my friends for their weddings. Her response to any teasing is that at least that mistake investment is beating the stock market over the same period, and she'll always need stamps.

So much cool stuff about the article and comments. Awal making important remarks, RD on power factor, baldinho's questions, and more. Joel's interest in DC transmission is interesting. Impedance is the problem and DC beats it. Maybe DC can go underground, without impedance, although as shrink says, heat is still a consideration.

Power factor is often treated by running motors with no load. This is the point beyond which I am lost, but if somehow this could be incorporated into flywheels, then problems mentioned by RD (better batteries & power factor) might combine into a single solution.

Boo on Xcel Energy, Awal.

baldinho, someone picked 40 miles as optimum range on some of our current electric car production for probably a good reason. Battery weight. I think it would take more than a rooftop for a regular 40 mi./day run.

Jumper - there are kinetic storage systems based on high-velocity flywheels. The design is similar to high speed centrifuges. And you can store a lot of energy this way. The problem is that these things are intrinsically unstable - especially when they are being spun up or spun down. One small imperfection and it all goes big-time kafluey. Which means that they have to be made with great precision, which is pricey.

My one run-in with flywheels is a memory I have from college as we were "designing" a solar field to power some mid-sized city or somethingorother. The instructor mentioned that we could size the array based on 80 or 90 percent efficiency... since we were going to use flywheels to store the energy.

It all seemed very pie in the sky then. Are flywheels actually in use that are that efficient?

That was about 22 or so years ago. I don't know if I have heard flywheels mentioned much since then.... though I don't read lots of solar industry journals.

What I need in the electric car that I would buy is a battery that can be readily changed out. It has to weight something south of 40 lbs. I need to be able to charge the aforementioned 6 or so batteries with my stand-alone solar setup and have them ready to swap in and out of my car.

I charge 6 batteries, each with maybe 40 miles of go. I pop one in for the 20 mile commute to work. I store 2 more. One for the ride home. One just in case. If I get home I have 3 more ready to go. I plug the 3 I took with me to work back in, etc.

The day/night charging thing would be tricky, so I might need the ability to plug the charger in to a conventional source if my needs are too much for the solar generator.

I read recently that people envision a nationwide network of battery changing/charging stations similar in design. You drive 40 or 50 or 80 miles or whatever then pull into a charging/changing station. You offload the dead battery, plug it in and take a charged battery. You pay a fee to do so that is less than the equivalent gasoline.

My setup would restrict me to a 50 or so mile radius from my house. That doesn't bother me, as I would likely have a second car that is a traditional gasoline car anyway.

On the electric car topic - they used flywheel storage (KERS, or Kinetic Energy Recovery System) in McLaren and Ferrari Formula 1 race cars last year as an experiment in electrical suppliment to gasoline engines. Any team was allowed to use it, but only the two raced working versions of it, if memory serves.

IIRC there was a two-step system featuring batteries and regenerative braking systems to keep the flwheels spun up, and electric motors to suppliment the rear wheel drive (though they could have just as well applied it to all 4 tires, I suppose). To RD's points, there were some downsides to the systems, one of which was the dangers of high-speed flywheel storage, should things go cattywumpus (they never did in that respect) and the drivers having to learn to get themselves out of cars without making accidental paths to ground in the event that the high-capacity electrical systems find a path to the chassis. Completing that circuit to ground in those crates theoretically had enough juice to kill muy pronto, though no one tested that theory, thank goodness. Its use was suspended for this year due to some other rules changes (such as banning refueling during the race), though the FIA says they will allow for newer versions of KERS next season, and may mandate it for 2012.

Not saying those guys have all the answers, but this may be another crucible (and a lot of money) to speed up development of such technologies.

I hope that fan who fell from the second deck in Texas - and those underneath him - recover soon ... I'll be thinking about those folks, and some of my fellow Boodlers here tonight.

baldinho1 - Nothing to it, as long as you can eschew the usual addiction to improperly-short following distances and unnecessary acceleration. Unfortunately, the driving habits of those around you will tend to affect that.

Quite simply, most non-commercial-haul drivers could get around fine with petroleum-based engines getting nearly quadruple current mileage rates if they had better driving habits.

You could get around fine with a slow, heavy electric car charged by a combination of your own solar cells, small wind turby, and a primitive fuel cell, if you were willing to adopt the same (slow-but-steady) driving habits.

In case you were wondering, this is all going to happen eventually. It's just a matter of waiting until it's very obvious that it's cheaper to do it the right way than it is to do it the faster way. At the moment, it's not yet obvious to enough people. So be it. The change of commuters' mind-set is slow, but the decrease in the availability of cheap energy-dense carbon fuels is patient.

And that hydrogen storage thing that "they" keep saying isn't practical? That's also on the way.

Shrink, I took theatre history, and my professor explained that the Greeks believed that even the Gods were bound by fate.

They also tended to understand insanity and crime as caused by blood curses-- that an ancestor had offended the gods by committing sacrilege and brought down a curse on their descendants.

So, when you watch the Oresteid, it matters that Agamemnon is descended from Pelops, the son killed by Tantalus and served to the gods as a feast. Pelops was returned to life and became a king and had many children. King Atreus was one son, and he and his brother were banished after they murdered their half-brother, a favorite of Pelops.
King Atreus was Agamemnon's father, and Agamemnon himself sacrified his daughter Iphigenia, not just to mollify the gods and for political purposes-- but he himself insisted on doing the actual murder.

So, this house was sick and twisted, and incidentally ruled city-states that were foes of Athens. Orestes was handled an impossible moral dilemna-- avenge his father only by the blood-crime of killing his mum. He was damned if he did, damned if he didn't. He is driven mad by the furies. The end solution, given by the gods, is to have the state administer justice, rather than depending on blood feud or DIY justice which could lead to unspeakable crimes that could twist and haunt a family forever.

It was also a trumpet for Athenian democratic rule over these corrupt dynasties, too.

So schaudenfreude, no. Just plain old-fashioned monster stories-- monsters with the faces of people, and how other people can carry pain and twists that they never asked for, except by being born to the wrong family. The release comes in seeing atonement with the gods for the wrongs done by their ancestors, seeking balance somehow. Sometimes that is simply not possible, and they suffer until the Gods step in and give them a second chance somehow-- restore the dead son, try Orestes and pardon them.

Medea, my teacher said, is an example of the monstrous women; dominant, powerful, full of warrior-passion, and dangerous. Yet she is given realistic motives for being hurt and ready to seek revenge for adultery. The difference is not in how she feels, but what she does about it. She kills their children just to hurt him. She can't think about anybody but herself; after all she betrayed her father killed her own brother to run off with Jason. That's kind of a warning sign there, but Jason was happy to use her as long as her obsession benefitted his own agenda.

My $0.01 on divorce. My 'rents never did figure out how to be married to each other and my siblings and I kept crossing our fingers with every major blow-up hoping it would be the one that would end the marriage for good. When they finally split (I was 17), we were relieved to be able to breathe.

My point is not to get concerned just because kids are involved. There are lots of dynamics involved and the kids may not always readily voice all of their feelings on the subject, especially to other adults.

[Sidebar: one 'rent has passed away, but the other has been happily married for over 30 years to someone else. Divorce is obviously a closing of at least one door, but can open so many others.]

Regarding the differences between DC and AC power transmission, what DC transmission has in its favor is the elimination of "skin effect." Skin effect is caused by the expanding and contracting electromagnetic flux (ha!) in the conductor forcing the electrons to the outside or skin of the conductor. This only happens during AC transmission. By forcing the electrons to the skin of the conductor, the conductor's cross-section electrically decreases, the resistance (not the impedance) is increased, and the conductor heats up, causing a loss.

Impedance, in and of itself, is loss-less. Impedance is a result of the inductive and capacitive elements (called reactance) of the conductor. The reactive elements of a large,(nearly) straight transmission line is really, really small. Any loss attributed to these elements is due to resistive heating of the conductors.

Skin effect increases with an increase in the frequency. This is why some RF conductors are silver-plated (silver is a better conductor than copper) or even hollow, as little current flows in the center of the conductor.

The skin effect IS very small at 60Hz but much larger than reactive losses. The total heat loss due to skin effect at multi-megawatt transmission levels is considerable. DC transmission allows smaller conductors or higher power levels because it can use all of the conductor.

Some vandalism, a few relatively inexpensive items stolen, and lots of food meant for daily snack gone. The items that teens value most were untouched, like the big flat screen TV. This leads us to believe it is the third case of some of the same kids we see every day doing the damage. Listened to Speaking of Faith on Sunday and was struck by a monk who said the difference between what he and his fellows do and the usual social justice types (me I guess) is that SJers burn out.

(http://www.mnstate.edu/gracyk/courses/web%20publishing/AristotlePoeticsEdited.htm):

7. Tragedy, then, is an imitation of an action that is serious, complete, and of a certain magnitude; in language embellished with each kind of artistic ornament, the several kinds being found in separate parts of the play; in the form of action, not of narrative; through pity and fear effecting the proper purgation [catharsis] of these emotions. By 'language embellished,' I mean language into which rhythm, 'harmony' and song enter. . . .

(Aristotle, Poetics, 1449b25f if you want to look up the Greek on the Perseus site.)

Shrink - I don't have those figures in front of me but that information may be available on the internet. The loss figure depends on where you start your measurement. If your friend is starting with the POTENTIAL power that is in the weight of the water in the dam and figure in the losses in the turbines that run the primary DC generators, the losses in the motor-generator set (or electronic inverter) that turns the DC into AC, losses in transformers and transmission lines, then yes, I could see close to a total 50% power loss, maybe more.

If you are measuring the loss from the output of the AC generator to the home (ie transmission loss) then I think you are looking at about 10%. But that is a WAG, again I don't have the figures in front of me.

The main loss would be in the turbines running the DC generators. I would think at best that they could extract only 65%-75% of the potential from the weight of the water flowing through them.

As I said though, your friend would have to clarify where his starting and ending measurements were taken from.

So, you are thinking, why bother with a 3% improvement in the efficiency of the transmission lines? The answer of course lies in the miles and miles and tons and tons of copper required to get the power from one place to another. Not to mention towers, land leasing/purchases, maintenance, on and on.
