Blackout tracker tells you where the electric grid is down

The other day, someone asked me what the most surprising thing was that I learned while writing Before the Lights Go Out, my book about America's electric infrastructure and the future of energy. That's easy. The most surprising thing was definitely my realization of just how precarious our all-important grid system actually is.

There are two key things here. First, the grid doesn't have any storage. (At least, none to speak of.) Second, the grid has to operate within a very narrow window of technical specifications. At any given moment, there must be almost exactly as much electricity being produced as there is being consumed. If that balance is thrown off, by even a fraction of a percent, you start heading toward blackouts. There are people working 24-hours-a-day, 7-days-a-week, making sure that balance is maintained on a minute-by-minute basis.

That's a long way of explaining why I find Blackout Tracker so fascinating. Put together by Eaton, a company that makes products that help utilities manage different parts of the electric grid, this little web app shows you where the electric grid has recently failed, and why. The Blackout Tracker doesn't claim to include all blackouts, but it gives you an idea of the number of blackouts that happen, and the wide range of causes blackouts can have. For instance, in the picture above, you can see that Wichita, Kansas, had a blackout earlier this week that was related to a heatwave—hot weather meant more people turned on their air conditioners in the middle of the day, and, for whatever reason, there wasn't enough electrical supply available to meet that demand. The result: Blackout.

One major flaw: Most of the time Blackout Tracker can't tell you how long a blackout lasted. But that's probably got more to do with what information the utility companies are willing to release than anything. Still, I think this program is a nice primer for people who aren't aware of all the hard work that goes on behind the scenes to make sure electricity remains flowing, nice and steady.

  1. Cats cause more than keyboard failure, earthquakes and internet tube hairballs:

    “A frightened cat was responsible for a power outage: A car crashed into a utility pole, and the driver reported that her cat jumped on the floor on the driver’s side, causing her to lose control of the car.”

    “Frightened” my ass; the driver might have been frightened but the cat was aiming.

  2. This thing isn’t working in Indiana.  We’ve got something like half the eastern side of the state without power since yesterday, with estimates of repair times stretching to next Wednesday, and it’s not there at all.

  3. Definitely not the level of detail that anyone would find useful in this.  For the entire DC/MD/VA region, which still has over 500k people out, it’s showing very little info.
