Wow, the outage happened just last night. Give them time to figure it all out. I have an unofficial report that a power surge in Ohio started it from what they can tell right now. It has been traced to a house that was having a female toy party with 113 women in attendance. I guess they had some really powerful toys fire up all at once and caused a major draw all at once. J/K. My slant on this is to buy Northeast hosiptal stocks. You know in 9 months the birth rate is going to be majorly high. Have fun in the dark guys. I am confident it will be fixed soon. The Edison companies can't afford to be off line for long. Mark

How the hell does a power outage of this magnitude happen, and the don't know what caused it?
Another goddamn coverup.
folks in the USA are BABIED!! Go to a real third world country and you'll have power interuptions on a daily basis.
Also,unlike telephone and cable service-- when you don't have electricity you don't have to pay for it. I don't think it would be in utilities best interest to loose all that revenue.
I'd venture to say that most of the people on this board or country could'nt look at a simple distribution pole and tell the difference between the utilities attached to it.
Just amazes me, all the experts on news programs who don't know what their spouting. One electric linemans point of view.
Something failed-- a relay,generator,possible human error. There is no reason for a blackout this big. After the incident(what ever it was)something else failed to prevent the cascade affect.
This is a little bit more complicated than serving up a slurpy at your neighborhood store. Nobody ouside the industry really knows or cares about how it works. MAYBE that DOES more about saying how reliable the service is than anything.
I WOULD LIKE TO SAY GOOD JOB DEMONSTRATED BY THE PEOPLE AFFECTED,99 PERCENT ANYWAY.

Guys,I gotta confess.
It was me.It came down to the case of beer and the peeler or the electricity bill.
I ask you,which would you take?
Really?!

LONNNNNNNNNNNG!!!!
Fortunately it did not get to us, the lights are on and the AC is cranked.
Here's a quick explanation on how/why something like this can happen at this magnitude. Think of it as a group of 20 trucks (generators) pulling a single load (electrical load from customers) at a rate of 60 mph (generator frequency measured in Hz, North America is 60 Hz) You have a failure on one of the tow ropes pulling the load, that particular truck then speeds up until the point of overevving and blowing up (generator or group of generators on that particular grid trips). The other trucks have to push a little harder to maintain that speed of 60 mph, no problem they wont even notice it, then one starts to overheat, it breaks down and the others then have more load to carry and it CAN snowball from there.
Take this scenario....It is 100 degrees out everyone has their A/C cranking all the lights on etc etc etc. HEAVY LOAD, suppose a couple trucks are out of service and you are maxxed out on the remaining trucks, you have a tow rope failure (transmission lines become very vulnerable to failure in extreme heat and load conditions to begin with) the other trucks cannot maintain their speed, so for equipment safety reasons ( low or high generator frequency will trip a turbine/generator set to prevent damage from excessive heating or overspeed and destroying a 10 million dollar piece of equipment) they will just shut down to protect themselves. The reason it has to be so big is because the system frequency has to be maintained at 60 Hz and if you lose a couple generators,the system will compensate with the other generators on that particular grid. If it were broken down into smaller groups, say 3 generators for a city of 1,000,000 and you lost one because of a mechanical failure and then you had to take one off for maintenance, no way could one generator do it and you would have to take it off as well, then you have a city of 1,000,000 with no power until at least one other generator set was repaired and God only know how long that would be......

Should not of gotten that large that's for sure. The initial problem should have been isolated,there was a couple of failures for sure. On the bright side, for guys in my LINE of work it's easy overtime--no rain,lightning,wind,snow,cold, just easy switching.

21 units in 3 minutes, not a whole bunch of time to make decisions!!!!!!!!!!!!!!!!!!!!!
With the rate they are putting up homes/businesses here in MI, It doesn't surprize me there are failures in the system. More load in different areas. Also, don't forget that Robots make mistakes, so can humans.
I agree with a reminder on how reliable the system really is.
P.S. Buy a damn generator and keep some gas in store. Then this won't really be that big of a deal after all.
